-\subsection install_installing_cmake Installing cmake
+SimGrid should work out of the box on Linux, Mac OSX, FreeBSD, and Windows (under windows, only the Java interfaces are
+available at the moment).
-You must have cmake in order to compile SimGrid. If you cannot find a
-binary package of cmake for your system, you'll need to recompile it.
-In turn, cmake has a few dependencies:
+The easiest way to install SimGrid is to go for a @ref install_binary "binary package". Under Debian or Ubuntu, this is
+very easy as SimGrid is directly integrated to the official repositories. For other Linux variants, you probably want
+to go for a @ref install_src "source install". Please contact us if you want to contribute the build scripts for your
+preferred distribution. If you just want to use @ref install_binary_java "Java", simply copy the jar file on your disk
+and you're set.
-For Unix and MacOS:
- \li make
- \li perl and libpcre
- \li c and c++ compiler
- \li ccmake for graphical used of CMake
- \li cmake <a href="http://www.cmake.org/cmake/resources/software.html">(download page)</a>
+@section install_binary Installing a binary package
-On MacOSX some users reported that it is still possible to build with clang, provided that you
-use at least clang3.0 installed with macport or with xcode. If it fails on you, try to
- use gcc47.
-\verbatim
-port install clang-3.0
-port install gcc47
-\endverbatim
+@subsection install_binary_linux Binary packages for linux
-For Windows:
- \li cmake 2.8 <a href="http://www.cmake.org/cmake/resources/software.html">(download page)</a>
- \li MinGW <a href="http://sourceforge.net/projects/mingw/files/MinGW/">(download page)</a>
- \li perl <a href="http://www.activestate.com/activeperl/downloads">(download page)</a>
- \li git <a href="http://msysgit.googlecode.com/files/Git-1.7.4-preview20110204.exe">(download page)</a>
+Most of the developers use a Debian or Ubuntu system, and some of us happen to be Debian Maintainers, so the packages
+for these systems are well integrated with these systems and very up-to-date. To install them, simply type:
-Note that if you want change the compiler, you can simply specify the environment variables CC and CXX.
-\verbatim
- export CC=gcc-4.4
- export CXX=g++-4.4
- export CC=clang
- export CXX=clang++
-\endverbatim

+The easiest way to install the Java bindings of SimGrid is to grab the jar file from the
+[download page](https://gforge.inria.fr/frs/?group_id=12) and copy it in your classpath (typically, in the same
+directory as your source code). If you go for that version, there is no need to install the C library as it is already
+bundled within the jar file. Actually, only a bunch of architectures are supported this way to keep the jar file size
+under control and because we don't have access to every exotic architectures ourselves.
- \li enable_gtnets: set to true implies that user wants to use gtnets.
+If the jarfile fails on you, complaining that your architecture is not supported, drop us an email on
+<mailto:simgrid-devel@lists.gforge.inria.fr>. We may extend the jarfile for you, provided we have access to this
+particular architecture to build SimGrid on it.
- \li enable_ns3: set to true implies that user wants to use ns3.
+If the error message is about the boost-context library, then you should install that library on your machine. This is
+a known issue in the 3.12 release that will be fixed in the next release.
- \li enable_lua: set to true implies that user wants to add lua language into simgrid compilation.
+You can retrieve a nightly build of the jar file from our autobuilders.
+For Windows, head to [AppVeyor](https://ci.appveyor.com/project/mquinson/simgrid).
+Click on the artefact link on the right, and grab your file. If the latest build failed, there will be no artefact. Then
+you will need to first click on "History" on the top and search for the last successful build.
+For non-Windows systems (Linux, Mac or FreeBSD), head to [Jenkins](https://ci.inria.fr/simgrid/job/SimGrid-Multi).
+In the build history, pick the last green (or at least yellow) build that is not blinking (i.e., not currently under
+build). In the list, pick a system that is close to yours, and click on the ball in the Debug row. The build artefact
+will appear on the top of the resulting page.
- \li enable_compile_optimizations: add flags "-O3 -finline-functions -funroll-loops -fno-strict-aliasing"
+@section install_src Installing from source
- \li enable_compile_warnings: add flags "-Wall -Wunused -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wcomment -Wformat -Wwrite-strings -Wno-unused-function -Wno-unused-parameter -Wno-strict-aliasing -Wno-format-nonliteral -Werror"
+@subsection install_src_deps Resolving the dependencies
- \li enable_smpi: Set to true if you want to use smpi lib. Actually on simgrid v3.4.1 Mac doesn't support lib smpi.
+Recompiling an official archive is not much more complex. SimGrid only uses very standard tools:
+ - C compiler, C++ compiler, make and friends.
+ - perl (but you may try to go without it)
+ - We use cmake to configure our compilation
+ ([download page](http://www.cmake.org/cmake/resources/software.html)).
+ You need cmake version 2.8.8 or higher. You may want to use ccmake
+ for a graphical interface over cmake.
+ - LibBoost:
+ - osX: with [fink](http://www.finkproject.org/): `fink install boost1.53.nopython`,
+ or with homebrew: `brew install boost`
+ - debian/ubuntu: `apt-get install libboost-dev libboost-context-dev`
+ - Java (only needed if you want to use the Java bindings): Grab a
+ [full JDK](http://www.oracle.com/technetwork/java/javase/downloads)
- \li enable_maintainer_mode: set to true it remakes some files.
+For platform specific details, please see @ref install_cmake_mac and @ref install_cmake_windows.
- \li enable_tracing: To enable the generation of simulation traces for visualization.
+@subsection install_src_fetch Getting the sources
- \li enable_coverage: When set to true this option enable code coverage by setting -fprofile-arcs -ftest-coverage flags.
+You can download the *@SimGridRelease.tar.gz* archive from the
+[download page](https://gforge.inria.fr/frs/?group_id=12).
+Then, recompiling the archive should be done in a few lines:
- \li enable_memcheck: When set to true this option enable tests for memcheck.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.sh}
+tar xf @SimGridRelease.tar.gz
+cd @SimGridRelease
+cmake -DCMAKE_INSTALL_PREFIX=/opt/simgrid .
+make
+make install
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- \li enable_model-checking: Enable the model checking when set to true.
+If you want to stay on the bleeding edge, you should get the latest git version, and recompile it as you would do for
+an official archive. Depending on the files you change in the source tree, some extra tools may be needed.
- \li enable_debug: If enable_debug is set to 'off' Simgrid compile flag has '-DNDEBUG' option.
+@verbatim
+git clone git://scm.gforge.inria.fr/simgrid/simgrid.git simgrid
+@endverbatim
- \li enable_jedule: To enable jedule mode, which creates visualizations of task schedules with Simdag.
+@subsection install_src_config Configuring the build
- \li enable_latency_bound_tracking: Set to on if you want to be warned when communications are limited by round trip time.
+Note that compile-time options are very different from @ref options "run-time options".
- \li enable_lib_static: Enable generated Simgrid and smpi static libraries.
+\subsubsection install_cmake_howto Setting compilation options
- \li enable_supernovae: Set to true make one file for each lib and compile with those generated files.
+The default configuration should be fine for most usages, but if you need to change something, there are several ways
+to do so. First, you can use environment variables. For example, you can change the compilers used by issuing these
+commands before launching cmake:
- \li enable_msg_deprecated: Simgrid is compiled with msg deprecated functions.
+@verbatim
+export CC=gcc-4.7
+export CXX=g++-4.7
+@endverbatim
- \li enable_print_message: When set to true configuration print more debug output.
+Note that other variables are available, such as CFLAGS and CXXFLAGS to add options respectively for the C and C++
+compilers.
- \li gtnets_path: Path to gtnets install directory (ex /usr)
+Another way to do so is to use the -D argument of cmake as follows. Note that the terminating dot is mandatory (see @ref
+install_cmake_outsrc to understand its meaning).
- \li ns3_path: Path to ns3 install directory (ex /usr)
+@verbatim
+cmake -DCC=clang -DCXX=clang++ .
+@endverbatim
- \li CMAKE_INSTALL_PREFIX: Path where are installed lib/ doc/ and include/ directories (ex /usr/local)
+Finally, you can use a graphical interface such as ccmake to change these settings. Simply follow the instructions after
+starting the interface.
- \li pipol_user: specify your pipol username if you want to use the pipol-remote command.
+@verbatim
+ccmake .
+@endverbatim
-\subsubsection install_cmakeoption3 Initialization
+\subsubsection install_cmake_list SimGrid compilation options
-Those options are initialized the first time you launch "cmake ." without specified option.
+In addition to the classical cmake configuration variables, SimGrid accepts several options, as listed below.
-\verbatim
-enable_gtnets on
-enable_lua on
-enable_smpi on
-enable_tracing on
-enable_compile_optimizations on
-enable_debug on
-enable_compile_warnings off
-enable_maintainer_mode off
-enable_coverage off
-enable_memcheck off
-enable_model-checking off
-enable_jedule off
-enable_latency_bound_tracking off
-enable_lib_static off
-CMAKE_INSTALL_PREFIX /usr/local
-gtnets_path null
-pipol_user null
-\endverbatim
+ @li <b>CMAKE_INSTALL_PREFIX</b> (path): Where to install SimGrid (/opt/simgrid, /usr/local, or elsewhere).
-\subsubsection install_cmakeoption4 How to reset the cache of options
+ @li <b>enable_compile_optimizations</b> (ON/OFF) to request the compiler to produce efficient code. You want to
+ activate it, unless you plan to debug SimGrid itself. Indeed, efficient code may be appear mangled to debuggers.
-When options have been set they are keep into a cache file named "CMakeCache.txt". So if you want
-reset values you just delete this file located to the project directory.
+ @li <b>enable_compile_warnings</b> (ON/OFF) to request the compiler to issue error messages whenever the source code
+ is not perfectly clean. If you are a SimGrid developer, you have to activate this option to enforce the code
+ quality. As a regular user, this option is likely to bring you issues only.
-\subsection install_cmakecompilation Cmake compilation
+ @li <b>enable_debug</b> (ON/OFF) allows to discard all log messages of gravity debug or below at compile time, if
+ simulation speed matters. As there is quite a bunch of such log messages in SimGrid internals, this can reveal
+ faster than discarding them at runtime as usual. However, it obviously becomes impossible to get any debug
+ message from SimGrid if something goes wrong.
-\subsubsection install_cmakecompilation1 With command line.
+ @li <b>enable_documentation</b> (ON/OFF) to generate the documentation pages.
-On Unix or Mac platform:
+ @li <b>enable_java</b> (ON/OFF) to enjoy the java bindings of SimGrid.
-\verbatim
-cmake -D[name]=[value] ... ./
-make
-\endverbatim
+ @li <b>enable_jedule</b> (ON/OFF) to get SimDag producing execution traces that can then be visualized with the
+ Jedule external tool.
-On Windows platform:
+ @li <b>enable_lua</b> (ON/OFF) to enjoy the lua bindings of SimGrid. It adds an extra dependency on the lua library
+ and developer header files.
-\verbatim
-cmake -G"MinGW Makefiles" -D[name]=[value] ... ./
-mingw32-make
-\endverbatim
+ @li <b>enable_lib_in_jar</b> (ON/OFF) to XXX
-\subsubsection install_cmakecompilation2 With ccmake tool.
+ @li <b>enable_lto</b> (ON/OFF) to XXX
-\verbatim
-"ccmake ./"
-\endverbatim
-Then follow instructions.
+ @li <b>enable_maintainer_mode</b> (ON/OFF) is only needed if you plan to modify very specific parts of SimGrid
+ (e.g., the XML parsers and other related elements). Moreover, this adds an extra dependency on flex and flexml.
-\subsubsection install_cmakecompilation2bis Build out of source.
+ @li <b>enable_mallocators</b> (ON/OFF) has to be disabled when tracking memory issues within SimGrid, or the caching
+ mechanism used internally will fool the debuggers.
-As cmake generate many files used for compilation, we recommend to make a build directory.
-For examples you can make:
+ @li <b>enable_model-checking</b> (ON/OFF) if you actually plan to use the model-checking feature of
+ SimGrid. This execution mode is still under heavy work, but should be rather usable now. Be <b>warned</b> that
+ this option will hinder simulation speed even if you simulate without activating the model-checker. We are
+ working on improving this situation.

-\endverbatim
+By default, the files produced during the compilation are placed in
+the source directory. As compilation generates a lot of files, it
+is advised to put them all in a separate directory. It is then
+easier to cleanup, and this allows to compile several configurations
+out of the same source tree. For that, simply enter the directory
+where you want the produced files to land, and invoke cmake (or
+ccmake) with the full path to the SimGrid source as last argument.
+This approach is called "out-of-source-tree compilation".
-If you want to test before make a commit you can simply make "ctest -D Experimental" and then you can visualize results submitted into Cdash. <a href="http://cdash.inria.fr/CDash/index.php?project=Simgrid">(Go to Cdash site)</a>.

+\subsubsection install_cmake_mac Building on Mac OS X
-\subsubsection install_cmakeinstall1 From Git.
+SimGrid compiles like a charm with clang (version 3.0 or higher) on Mac OS X:
-\verbatim
-git clone git://scm.gforge.inria.fr/simgrid/simgrid.git simgrid
-cd simgrid
-cmake -Denable_maintainer_mode=on -DCMAKE_INSTALL_PREFIX=/home/navarrop/Bureau/install_simgrid ./
+@verbatim

-\endverbatim
-
-\subsubsection install_cmakeinstall2 From a distrib
-
-\verbatim
-wget https://gforge.inria.fr/frs/download.php/28674/simgrid-3.6.1.tar.gz
-tar xf simgrid-3.6.1.tar.gz
-cd simgrid-3.6.1
-cmake -DCMAKE_INSTALL_PREFIX=/home/navarrop/Bureau/install_simgrid ./
+@endverbatim
+
+With the XCode version of clang 4.1, you may get the following error message:
+@verbatim
+CMake Error: Parse error in cache file build_dir/CMakeCache.txt. Offending entry: /SDKs/MacOSX10.8.sdk
+@endverbatim
+
+In that case, edit the CMakeCache.txt file directly, so that the
+CMAKE_OSX_SYSROOT is similar to the following. Don't worry about the
+warning that the "-pthread" argument is not used, if it appears.
+@verbatim
+CMAKE_OSX_SYSROOT:PATH=/Applications/XCode.app/Contents/Developer/Platforms/MacOSX.platform/Developer
+@endverbatim
+
+In the El Capitan version of Max OS X, Apple decided that users don't
+need no /usr/include directory anymore. If you are hit by this pure
+madness, just run the following command to restore that classical
+UNIX directory: `xcode-select -install`
+
+\subsubsection install_cmake_windows Building on Windows
+
+Building from the source on Windows, may be something of an adventure.
+We never managed to compile SimGrid with something else than MinGW-64
+ourselves. We usually use the
+<a href="http://www.activestate.com/activeperl/downloads">activestate</a>
+version of Perl, and the
+<a href="http://msysgit.googlecode.com/files/Git-1.7.4-preview20110204.exe">msys</a>
+version of git on this architecture, but YMMV. You can have a look at
+the configuration scripts in the appveyor.yml file, but you are
+basically on your own here. Sorry. We are not fluent with Windows so
+we cannot really help.
+
+The drawback of MinGW-64 is that the produced DLL are not compatible
+with MS Visual C. If you need it, <a href="http://clang.llvm.org/docs/MSVCCompatibility.html">clang-cl</a>
+sounds promising. If you manage to get something working, please tell
+us how you achieved it.

-\subsection install_Win_compile1 Compile a project "HelloWorld"
-
-In the SimGrid install directory you should have an HelloWorld project to explain you how to start
-compiling a source file. There are:
\verbatim
-- HelloWorld.c The example source file.
-- CMakeLists.txt It allows to configure the project.
-- FindPCRE.cmake This finds and links to the pcre library (Normally included
- into Simgrid directory "GnuWin32").
-- README This explaination.
+ctest # Launch all tests
+ctest -R msg # Launch only the tests which name match the string "msg"
+ctest -j4 # Launch all tests in parallel, at most 4 at the same time
+ctest --verbose # Display all details on what's going on
+ctest --output-on-failure # Only get verbose for the tests that fail
+
+ctest -R msg- -j5 --output-on-failure # You changed MSG and want to check that you didn't break anything, huh?
+ # That's fine, I do so all the time myself.
\endverbatim
-Now let's compile this example:
-\li Run windows shell "cmd".
-\li Open HelloWorld Directory ('cd' command line).
-\li Create a build directory and change directory. (optional)
-\li Type 'cmake -G"MinGW Makefiles" \<path_to_HelloWorld_project\>'
-\li Run mingw32-make
-\li You should obtain a runnable example ("HelloWorld.exe").
-
-For compiling your own code you can simply copy the HelloWorld project and rename source name. It will
-create a target with the same name of the source.
-
-\subsection install_Win_compile2 How to add and compile a new example
-
-\li Put your source file into the helloWord directory.
-\li Edit CMakeLists.txt by removing the Find Targets section and add those two lines into this section
-\verbatim
-################
-# FIND TARGETS #
-################
-#It creates a target called 'TARGET_NAME.exe' with the sources 'SOURCES'
-add_executable(TARGET_NAME SOURCES)
-#Links TARGET_NAME with simgrid and pcre
-target_link_libraries(TARGET_NAME simgrid pcre)
-\endverbatim
-\li To initialize and build your project, you'll need to run
-\verbatim
-cmake -G"MinGW Makefiles" \<path_to_HelloWorld_project\>
-\endverbatim
-\li Run "mingw32-make"
-\li You should obtain "TARGET_NAME.exe".

-\section install_mac Installing the SimGrid framework on Mac OS X
-
-The Mac OS X system is part of the UNIX family, but it exhibits some

-but recent OS X version provide only an ancient version of that tool
-in the hope to see the users switch to the LLVM compiler family. The
-problem is that SimGrid uses internal libraries of GCC, for stack
-manipulation for example. We are working on removing this dependency
-onto gcc to ease the build process, but this is still ongoing.
-
-For the time being, you need to get a recent version of GCC on your
-system to build SimGrid. Version 3.7.1 was successfully built on Mac
-Lion 10.7.4 using a GCC compiler retrieved from macport. The package
-used were gcc47, and the binary in the package were gcc-mp-4.7.

outside the SimGrid source tree and create your own working directory

-The first two lines indicates what should be build when typing make

+where i686-linux-gnu-gfortran can be implemented as:
+
+@verbatim
+#!/bin/sh
