Install the package.
Build packages with Clang
export CC=clang and (for C++)
export CXX=clang++ to your
/etc/makepkg.conf. If you are building with
debug also remove
DEBUG_CXXFLAGS as clang does not support it.
NB: For packages that specify GCC-specific build options, there may be build errors that require either editing the source package, the pkgbuild or commenting out the clang lines in makepkg.conf.
Using the Static Analyzer
To analyze a project, simply place the word
scan-build in front of your build command. For example:
$ scan-build make
scan-buildwon't rebuild and won't analyse it. To force recompilation and analysis, use
$ scan-build make -B
It is also possible to analyze specific files:
$ scan-build gcc -c t1.c t2.c
