OpenMandriva Can Now Clang Its Linux Kernel Build For This LLVM Focused Distribution

Mon, 09/30/2019 - 14:24
OpenMandriva is one of the few Linux distributions (and arguably the only prominent one) that uses LLVM Clang as its default compiler toolchain over GCC for building its packages and the preferred C/C++ compiler exposed to its users. One of the last hold outs for this Clang'ed Linux distribution has been the kernel build but that is now no longer a blocker...
