Building SOAAP and related tools

We are pleased to announce that an early prototype version of the Clang/LLVM- based SOAAP toolchain is now available to try out. Please send any queries to Khilan Gudka and Robert Watson.

Some preliminary notes:

  • Currently SOAAP is built, run and tested on FreeBSD 10.0.
  • Create a directory in which all soaap-related files will reside. In these instructions, we will assume the directory '/home/me/workspace' is used for this purpose.
  • CMake >= 2.8.9 and Ninja 1.0.0 are required to build Clang/LLVM and the Soaap LLVM pass.
  • SOAAP requires libc++ r194154 or newer. If you cannot build SOAAP, it might be because your libc++ isn't new enough. A more recent version can be installed from ports. The -DCMAKE_PREFIX_PATH=/usr/local below takes care of finding a ports installation of libc++.

SOAAP tool

[me@mymachine ~/workspace/llvm/Build]$ cd ../..
[me@mymachine ~/workspace]$ git clone --recursive
[me@mymachine ~/workspace]$ cd soaap
[me@mymachine ~/workspace/soaap]$ mkdir Build
[me@mymachine ~/workspace/soaap]$ cd Build
[me@mymachine ~/workspace/soaap/Build]$ cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=ON -DLLVM_DIR=`pwd`/../../llvm/Build/share/llvm/cmake -DCMAKE_C_COMPILER=`pwd`/../../llvm/Build/bin/clang -DCMAKE_CXX_COMPILER=`pwd`/../../llvm/Build/bin/clang++ -DCMAKE_PREFIX_PATH=/usr/local ..
[me@mymachine ~/workspace/soaap/Build]$ ninja

Everything is built and ready to use! Note that because SOAAP depends on submodules, you will need to ensure that they are updated when you pull from the SOAAP repo. This can be achieved by passing the --recurse-submodules flag to git pull, as in:

git pull --recurse-submodules
