-\section faq_installation Installing the SimGrid library
-
-Many people have been asking me questions on how to use SimGrid. Quite
-often, the questions were not really about SimGrid but on the
-installation process. This section is intended to help people that are
-not familiar with compiling C files under UNIX. If you follow these
-instructions and still have some troubles, drop an e-mail to
-<simgrid-user@lists.gforge.inria.fr>.
-
-\subsection faq_compiling Compiling SimGrid from a stable archive
-
-First of all, you need to download the latest version of SimGrid from
-<a href="http://gforge.inria.fr/frs/?group_id=12">here</a>.
-Suppose you have uncompressed SimGrid in some temporary location of
-your home directory (say <tt>/home/joe/tmp/simgrid-3.0.1 </tt>). The
-simplest way to use SimGrid is to install it in your home
-directory. Change your directory to
-<tt>/home/joe/tmp/simgrid-3.0.1</tt> and type
-
-\verbatim
-./configure --prefix=$HOME
-make
-make install
-\endverbatim
-
-If at some point, something fails, check the section \ref faq_trouble_compil .
-If it does not help, you can report this problem to the
-list but, please, avoid sending a laconic mail like "There is a problem. Is it
-okay?". Send the config.log file which is automatically generated by
-configure. Try to capture both the standard output and the error output of the
-<tt>make</tt> command with <tt>script</tt>. There is no way for us to help you
-without the relevant bits of information.
-
-Now, the following directory should have been created :
-
- \li <tt>/home/joe/doc/simgrid/html/</tt>
- \li <tt>/home/joe/lib/</tt>
- \li <tt>/home/joe/include/</tt>
-
-SimGrid is not a binary, it is a library. Both a static and a dynamic
-version are available. Here is what you can find if you try a <tt>ls
-/home/joe/lib</tt>:
-
-\verbatim libsimgrid.a libsimgrid.la libsimgrid.so libsimgrid.so.0 libsimgrid.so.0.0.1
-\endverbatim
-
-Thus, there is two ways to link your program with SimGrid:
- \li Either you use the static version, e.g
-\verbatim gcc libsimgrid.a -o MainProgram MainProgram.c
-\endverbatim
- In this case, all the SimGrid functions are directly
- included in <tt>MainProgram</tt> (hence a bigger binary).
- \li Either you use the dynamic version (the preferred method)
-\verbatim gcc -lsimgrid -o MainProgram MainProgram.c
-\endverbatim
- In this case, the SimGrid functions are not included in
- <tt>MainProgram</tt> and you need to set your environment
- variable in such a way that <tt>libsimgrid.so</tt> will be
- found at runtime. This can be done by adding the following
- line in your .bashrc (if you use bash and if you have
- installed the SimGrid libraries in your home directory):
-\verbatim export LD_LIBRARY_PATH=$HOME/lib/:$LD_LIBRARY_PATH
-\endverbatim
-
-\subsection faq_compiling_java Java bindings don't get compiled
-
-The configure script detects automatically whether you have the
-softwares needed to use the Java bindings or not. At the end of the
-configure, you can see the configuration picked by the script, which
-should look similar to
-\verbatim Configuration of package simgrid' (version 3.3.4-svn) on
-little64 (=4):
-
- Compiler: gcc (version: )
-
- CFlags: -O3 -finline-functions -funroll-loops -fno-strict-aliasing -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 -g3
- CPPFlags:
- LDFlags:
-
- Context backend: ucontext
- Compile Java: no
-
- Maintainer mode: no
- Supernovae mode: yes
-\endverbatim
-
-In this example, Java backends won't be compiled.
-
-On Debian-like systems (which includes ubuntu), you need the following
-packages: sun-java6-jdk libgcj10-dev. If you cannot find the
-libgcj10-dev, try another version, like libgcj9-dev (on Ubuntu before
-9.10) or libgcj11-dev (not released yet, but certainly one day).
-Please note that you need to activate the contrib and non-free
-repositories in Debian, and the universe ones in Ubuntu. Java comes at
-this price...
-
-\subsection faq_compiling_snapshoot SimGrid development snapshots
-
-We have very high standards on software quality, and we are reluctant releasing
-a stable release as long as there is still some known bug in the code base. In
-addition, we added quite an extensive test base, making sure that we correctly
-test the most important parts of the tool.
-
-As an unfortunate conclusion, there may be some time between the stable
-releases. If you want to benefit from the most recent features we introduced,
-but don't want to take the risk of an untested version from the SVN, then
-development snapshots are done for you.
-
-These are pre-releases of SimGrid that still fail some tests about features
-that almost nobody use, or on platforms not being in our core target (which is
-Linux, Mac, other Unixes and Windows, from the most important to the less
-one). That means that using this development releases should be safe for most
-users.
-
-These archives can be found on
-<a href="http://www.loria.fr/~quinson/simgrid.html">this web page</a>. Once you
-got the lastest archive, you can compile it just like any archive (see above).
-
-\subsection faq_compiling_svn Compiling SimGrid from the SVN
-
-The project development takes place in the SVN, where all changes are
-committed when they happen. Then every once in a while, we make sure that the
-code quality meets our standard and release an archive from the code in the
-SVN. We afterward go back to the development in the SVN. So, if you need a
-recently added feature and can afford some little problem with the stability
-of the lastest features, you may want to use the SVN version instead of a
-released one.
-
-For that, you first need to get the "simgrid" module from
-<a href="http://gforge.inria.fr/scm/?group_id=12">here</a>.
-
-You won't find any <tt>configure</tt> and a few other things
-(<tt>Makefile.in</tt>'s, documentation, ...) will be missing as well. The
-reason for that is that all these files have to be regenerated using the
-latest versions of <tt>autoconf</tt>, <tt>libtool</tt>, <tt>automake</tt>
-(>1.9) and <tt>doxygen</tt> (>1.4). To generate the <tt>configure</tt> and
-the <tt>Makefile.in</tt>'s, you just have to launch the <tt>bootstrap</tt>
-command that resides in the top of the source tree. Then just follow the
-instructions of Section \ref faq_compiling.
-
-We insist on the fact that you really need the latest versions of
-autoconf, automake and libtool. Doing this step on exotic architectures/systems
-(i.e. anything different from a recent linux distribution) may be
-... uncertain. If you need to compile the SVN version on a machine where all these
-dependencies are not met, the easiest is to do <tt>make dist</tt> in the SVN
-directory of another machine where all dependencies are met. It will create an
-archive you may deploy on other sites just as a regular stable release.
-
-In summary, the following commands will checkout the SVN, regenerate the
-configure script and friends, configure SimGrid and build it.
-
-\verbatim svn checkout svn://scm.gforge.inria.fr/svn/simgrid/simgrid/trunk simgrid
-cd simgrid
-./bootstrap
-./configure --enable-maintainer-mode --prefix=<where to install SimGrid>
-make \endverbatim
-
-Then, if you want to install SimGrid on the current box, just do:
-\verbatim make install \endverbatim
-
-If you want to build an snapshot of the SVN to deploy it on another box (for
-example because the other machine don't have the autotools), do:
-\verbatim make dist \endverbatim
-
-Moreover, you should never call the autotools manually since you must run
-them in a specific order with specific arguments. Most of the times, the
-makefiles will automatically call the tools for you. When it's not possible
-(such as the first time you checkout the SVN), use the ./bootstrap command
-to call them explicitly.
-
-
-\subsection faq_setting_MSG Setting up your own MSG code
-
-Do not build your simulator by modifying the SimGrid examples. Go
-outside the SimGrid source tree and create your own working directory
-(say <tt>/home/joe/SimGrid/MyFirstScheduler/</tt>).
-
-Suppose your simulation has the following structure (remember it is
-just an example to illustrate a possible way to compile everything;
-feel free to organize it as you want).
-
- \li <tt>sched.h</tt>: a description of the core of the
- scheduler (i.e. which functions are can be used by the
- agents). For example we could find the following functions
- (master, forwarder, slave).
-
- \li <tt>sched.c</tt>: a C file including <tt>sched.h</tt> and
- implementing the core of the scheduler. Most of these
- functions use the MSG functions defined in section \ref
- msg_gos_functions.
-
- \li <tt>masterslave.c</tt>: a C file with the main function, i.e.
- the MSG initialization (MSG_global_init()), the platform
- creation (e.g. with MSG_create_environment()), the
- deployment phase (e.g. with MSG_function_register() and
- MSG_launch_application()) and the call to
- MSG_main()).
-
-To compile such a program, we suggest to use the following
-Makefile. It is a generic Makefile that we have used many times with
-our students when we teach the C language.
-
-\verbatim
-all: masterslave
-masterslave: masterslave.o sched.o
-
-INSTALL_PATH = $$HOME
-CC = gcc
-PEDANTIC_PARANOID_FREAK = -O0 -Wshadow -Wcast-align \
- -Waggregate-return -Wmissing-prototypes -Wmissing-declarations \
- -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations \
- -Wmissing-noreturn -Wredundant-decls -Wnested-externs \
- -Wpointer-arith -Wwrite-strings -finline-functions

-
-%: %.o
- $(CC) $(INCLUDES) $(DEFS) $(CFLAGS) $^ $(LIBS) $(LDADD) -o $@
-
-%.o: %.c
- $(CC) $(INCLUDES) $(DEFS) $(CFLAGS) -c -o $@ $<
-
-clean:
- rm -f $(BIN_FILES) *.o *~
-.SUFFIXES:
-.PHONY : clean
-
-\endverbatim
-
-The first two lines indicates what should be build when typing make
-(<tt>masterslave</tt>) and of which files it is to be made of
-(<tt>masterslave.o</tt> and <tt>sched.o</tt>). This makefile assumes
-that you have set up correctly your <tt>LD_LIBRARY_PATH</tt> variable
-(look, there is a <tt>LDADD = -lm -lsimgrid</tt>). If you prefer using
-the static version, remove the <tt>-lsimgrid</tt> and add a
-<tt>$(INSTALL_PATH)/lib/libsimgrid.a</tt> on the next line, right
-after the <tt>LIBS = </tt>.
-
-More generally, if you have never written a Makefile by yourself, type
-in a terminal : <tt>info make</tt> and read the introduction. The
-previous example should be enough for a first try but you may want to
-perform some more complex compilations...
-
-\subsection faq_setting_GRAS Setting up your own GRAS code
-
-If you use the GRAS interface instead of the MSG one, then previous section
-is not the better source of information. Instead, you should check the GRAS
-tutorial in general, and the \ref GRAS_tut_tour_setup in particular.

+The first two lines indicates what should be build when typing make
+(<tt>masterslave</tt>) and of which files it is to be made of
+(<tt>masterslave.o</tt> and <tt>sched.o</tt>). This makefile assumes
+that you have set up correctly your <tt>LD_LIBRARY_PATH</tt> variable
+(look, there is a <tt>LDADD = -lm -lsimgrid</tt>). If you prefer using
+the static version, remove the <tt>-lsimgrid</tt> and add a
+<tt>$(INSTALL_PATH)/lib/libsimgrid.a</tt> on the next line, right
+after the <tt>LIBS = </tt>.
+
+More generally, if you have never written a Makefile by yourself, type
+in a terminal : <tt>info make</tt> and read the introduction. The
+previous example should be enough for a first try but you may want to
+perform some more complex compilations...
