Build Simit

To build Simit you must install CMake 2.8.3 or greater and LLVM 3.7 or greater. You must then make sure llvm-config is available in your path.

If you want to build LLVM yourself you can check it out using SVN:

svn co llvm3.7

then build it:

cd llvm3.7
mkdir build
cd build
make -j8

then point Simit to it:

export LLVM_CONFIG=/build/bin/llvm-config

To perform an out-of-tree build of Simit do:

mkdir build
cd build
cmake ..
make -j8

To run the test suite do (all tests should pass, but ignore disabled tests):


To check a Simit program:


For example:

./build/bin/simit-check apps/springs/isprings.sim

To make the Simit bin directory part of your PATH:

export PATH="$PATH:`pwd`/build/bin"

To build Simit's documentation:


This will create a doc directory containing HTML documentation. Open
