OpenBSD-specific notes

These information apply to OpenBSD. Feel free to contribute and add instructions for other BSD distribution if general information found in the main Readme do not directly apply.

Global configuration

  • Download and install the following tools from the OpenBSD packages directory :

      $ export PKG_PATH=http://ftp.openbsd.org/pub/OpenBSD/$(uname -r)/packages/$(uname -m)/
  $ pkg_add -i jre jdk cmake git subversion boost gcc g++ emacs tcl tk

    Make sure, when choice is offered, to install the latest version available of these tools, as required in the main Readme. Please note that default gcc version included in OpenBSD is too old for Mozart to compile.

  • The directory layout suggested in main Readme will be assumed here.

Compilation of Gtest

  1. Download Gtest in your <projects>/externals/gtest directory as suggested in the main Readme.

  2. In your terminal, launch Gtest compilation by typing :

     $ cd <projects>/builds/gtest-debug
 $ cmake -DCMAKE_C_COMPILER="egcc" -DCMAKE_CXX_COMPILER="eg++" -DCMAKE_BUILD_TYPE=Debug ../../externals/gtest
 $ make

    Note that the recent gcc you have installed is identified by egcc on OpenBSD and no confusion must be made to avoid compilation errors.

Compilation of LLVM

  1. Download LLVM in your <projects>/externals/llvm directory as suggested in the main Readme.

  2. In your terminal, launch LLVM compilation by typing :

     $ cd <projects>/builds/llvm-release
 $ cmake -DCMAKE_C_COMPILER="egcc" -DCMAKE_CXX_COMPILER="eg++" -DCMAKE_BUILD_TYPE=Release -DLLVM_TARGETS_TO_BUILD="X86" ../../externals/llvm
 $ make

    Please note that compilation may fail due to resource limitation. Use ulimit to temporarily change these values.

Compilation of Mozart 2

  1. Download Mozart in your <projects>/mozart2 directory as suggested in the main Readme.

  2. In your terminal, launch Mozart compilation by typing :

     $ cd <projects>/builds/mozart2-release
 $ cmake -DCMAKE_C_COMPILER="egcc" -DCMAKE_CXX_COMPILER="eg++" -DCMAKE_BUILD_TYPE=Release -DGTEST_SRC_DIR=../../externals/gtest -DGTEST_BUILD_DIR=../gtest-debug -DLLVM_SRC_DIR=../../externals/llvm -DLLVM_BUILD_DIR=../llvm-release -DCMAKE_CXX_FLAGS="-I/usr/local/include -I/usr/local/include/c++/4.8.2 -I/usr/local/include/c++/4.8.2/x86_64-unknown-openbsd5.5 -I/usr/X11R6/include -pthread -O3" -DCMAKE_INSTALL_PREFIX=../../redist ../../mozart2
 $ make

    Replace 4.8.2 and x86_64-unknown-openbsd5.5 by the folders corresponding to your gcc installation. You may need to add parameter -DCMAKE_CXX_LINK_FLAGS="-latomic" on some versions if linking fails with undefined references.

  3. To copy all the binaries in the redist folder, type :

     $ make install
