@subsection install_src_deps Getting the Dependencies
Recompiling an official archive is not much more complex. SimGrid only uses very standard tools:
- - C compiler, C++ compiler, make and friends.
+ - C compiler, C++ compiler, make and friends. SimGrid is rather
+ demanding on the compiler. We use the C++11 standard, and older
+ compilers tend to fail on us. It seems that g++ 5.0 or higher is
+ required nowadays (because of boost).
- 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)).
commands before launching cmake:
@verbatim
-export CC=gcc-4.7
-export CXX=g++-4.7
+export CC=gcc-5.1
+export CXX=g++-5.1
@endverbatim
Note that other variables are available, such as CFLAGS and CXXFLAGS to add options respectively for the C and C++
@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.
- @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.
+ @li <b>enable_mallocators</b> (ON/OFF) has to be disabled when tracking memory issues within SimGrid,
+ or our internal memory caching mechanism will fool the debuggers.
- @li <b>enable_model-checking</b> (ON/OFF) if you actually plan to
- use the model-checking feature of SimGrid. This execution mode
+ @li <b>enable_model-checking</b> (ON/OFF) This execution gear
is very usable now, but enabling this option at compile time
will **hinder simulation speed** even when the model-checker is
not activated at run time.
