| | 86 | |
| | 87 | Although the {{{build.sh}}} script should be sufficient in more cases, sometimes it can not |
| | 88 | detect where certain libraries are located. This is often true for the MPI example and for |
| | 89 | compiling the MTO with Boost. |
| | 90 | The build settings can be modified by setting the following environment variables: |
| | 91 | |
| | 92 | ||= Variable ||= Setting ||= Example || |
| | 93 | || BOOST_INCLUDEDIR || Location of Boost headers || {{{/opt/boost/include}}} || |
| | 94 | || BOOST_LIBRARYDIR || Location of Boost libraries || {{{/opt/boost/lib}}} |||| MPI_C_COMPILER || Compiler used for the C MPI example || {{{/usr/bin/mpicc}}} || |
| | 95 | || MPI_C_FLAGS || Flags to give the C MPI compiler || {{{-O3 -Wall}}} || |
| | 96 | || MPI_C_INCLUDE_PATH || Location of include files for C MPI || {{{/usr/include}}} || |
| | 97 | || MPI_C_LIBRARIES || All libraries needed to link with for C MPI (semicolon separated) || {{{/usr/lib/libmpi.so;/usr/lib/libm.so}}} || |
| | 98 | |
| | 99 | Possible build options can be evaluated by going to the build directory and running |
| | 100 | {{{ |
| | 101 | cmake -L .. |
| | 102 | }}} |
| | 103 | |
| | 104 | Even more detailed build options are found with |
| | 105 | {{{ |
| | 106 | cmake -LA .. |
| | 107 | }}} |
| | 108 | |
| | 109 | These options can be passed to cmake by setting the environment variable |
| | 110 | {{{ |
| | 111 | export MUSCLE_CMAKE_OPTIONS="-DOPTION=VALUE -DOPTION2=VALUE2" |
| | 112 | }}} |
| | 113 | For example, to build the python extension: |
| | 114 | {{{ |
| | 115 | export MUSCLE_CMAKE_OPTIONS="-DBUILD_PYTHON=ON" |
| | 116 | sudo ./build.sh |
| | 117 | }}} |
| | 118 | And if the libraries can not be found |
| | 119 | {{{ |
| | 120 | export MUSCLE_CMAKE_OPTIONS="-DBUILD_PYTHON=ON -DPYTHON_INCLUDE_DIR=/usr/include/python2.7 -DPYTHON_LIBRARY=/usr/lib/libpython2.7.so" |
| | 121 | sudo ./build.sh |
