llvm dev - Sep 2017 - Build clang front end only for few languages ( say C and C++ )

Hi,

 I am trying to build clang, however the build size is quite large. As
clang supports non-C family languages as well ( e.g. Java, Fortran ), is
there a way to turn that off during the build. I just want to have support
for C and C++ and don't care about other languages.

Is there a CMake option that needs to be set to do that??

Thanks a lot!

Best Regards,

Nitish

Hi,

Are you sure you ar not mixing things? Clang is the frontend for C 
family languages (and name of compiler using it) . There are LLVM based 
compilers for other languages but those are different projects and  not 
part of clang or llvm repositories. According to 
https://github.com/llvm-mirror/clang/blob/2c146e57031cf4692ecf1924c3d6d7e79851a984/docs/Toolchain.rst#id15
clang contains small amount of code for invoking GCC based fortran and 
java compilers and clangFormat but I doubt those add a significant size 
increase compared to the rest of clang.


Best regards,

Kārlis Seņko
