The instructions below assume you are in $HOME/hcc. The compiler would be built under $HOME/hcc/build. The OpenMP runtime would be put under $HOME/hcc/openmp.
Build HCC and OpenMP runtime
HCC now comes with OpenMP support by default. But to run OpenMP programs, you’ll need to build OpenMP runtime separately.
- HCC: HCC compiler
- OpenMP runtime
git clone https://bitbucket.org/multicoreware/hcc.git src mkdir build cd build cmake ../src make -j4 world make -j4 sudo make install export HCC_HOME=/opt/hcc export PATH=$HCC_HOME/bin:$PATH
The instructions below assume you are in $HOME/hcc. The build assumes x86-64 architecture.
svn co http://llvm.org/svn/llvm-project/openmp/trunk openmp cd openmp svn up -r238878 cd runtime make compiler=clang arch=x86_64 export C_INCLUDE_PATH=$HOME/hcc/openmp/runtime/exports/common/include:$C_INCLUDE_PATH export CPLUS_INCLUDE_PATH=$HOME/hcc/openmp/runtime/exports/common/include:$CPLUS_INCLUDE_PATH export LIBRARY_PATH=$HOME/hcc/openmp/runtime/exports/lin_32e/lib:$LIBRARY_PATH export LD_LIBRARY_PATH=$HOME/hcc/openmp/runtime/exports/lin_32e/lib:$LD_LIBRARY_PATH
Note: You need to set all environment variables mentioned above with HCC-OpenMP Compiler and OpenMP runtime.
This step compiles and runs the OpenMP samples required:
cd src/omp-sample ./compile_exec.sh
You should be able to see all samples compiled and executed without error message.
OpenMP3.1_Validation (OpenUH OpenMP test suite)
cd src/OpenMP3.1_Validation make clean make ctest
Note that you will encounter a build error with make clean in the first time, that’s a normal situation.
S Number of failed tests should be 7. These test cases are not supported by upstream clang-omp, so the we cannot yet be supported in Kalmar, and we consider this being regression-free.
