Building libmraa
libmraa uses cmake in order to make compilation relatively painless. Cmake runs build out of tree so the recommended way is to clone from git and make a build/ directory.
You'll need swig version 3.0.1+, currently I'm using 8d226e39dc7a958013ff9ffd15e231ef206ba265 from the swig master branch. This is only required for javascript support and can be disabled with a cmake define (see below).
mkdir build
cd build
cmake ..
make
Our cmake configure has a number of options, cmake-gui or ccmake can show you all the options. The interesting ones are detailed below:
Few recommended options: Changing install path from /usr/local to /usr -DCMAKE_INSTALL_PREFIX:PATH=/usr
Building debug build: -DCMAKE_BUILD_TYPE=DEBUG
Using clang instead of gcc: -DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang
Building with an older version of swig (swig 2.0+) requires the disabling of javascript: -DBUILDSWIGNODE=OFF
Disabling python module building -DBUILDSWIGPYTHON=OFF
Building doc, this will require sphinx & doxygen -BUILDDOC=ON
Using a yocto/oe toolchain
In order to compile with a yocto/oe toolchain use the following toolchain file. This works well on the edison 1.6 SDK. First source the environment file, then use our cmake toolchain file.
source /opt/poky-edison/1.6/environment-setup-core2-32-poky-linux
mkdir build
cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchains/oe-sdk_cross.cmake ..
make
Using coverity
Static analysis is routinely performed using coverity on libmraa's codebase. This is the procedure to submit a build to coverity. You'll need to install coverity-submit for your OS.
mkdir covbuild/ && cd covbuild
cmake -DBUILDDOC=OFF -DBUILDSWIG=OFF ..
cmake -DBUILDDOC=OFF -DBUILDSWIG=OFF ..
cov-build --dir cov-int make
tar caf mraa.tar..bz2 cov-int
