Hello Experts,

I am trying to use a different compiler other than gcc to compile gem5.
Is there a way to edit the Sconscript or some other config file to do this
easily ?
I want to set CC=<my new compiler>
The purpose is to add some instrumentation code while compiling to collect
coverage info.

Thanks

Hi,

I'm not sure if there's a way of compiling gem5 using clang via scons in a
system having both clang and gcc. However, the compiler tests do test
compiling gem5 in containers having either gcc or clang as the primary
compiler.

Hoa Nguyen

Hi,

Here is a patch from my personal modifications to SConstruct. It makes scons use the system-wide cc/c++ aliases that you can rebind to your liking with, e.g., update-alternatives on ubuntu. I’ve tested it successfully with several flavors of gcc/clang together with the ld or lld linker (the later being noticeably faster on my system). In any case, you can adapt the patch to hardcode your compiler in it. Beware with the compiler version checking that is a bit picky ;)

Can I use another c++ compiler to build gem5 ?
