 |
|
I followed https://wiki.gentoo.org/wiki/Clang#Advanced_examples
/etc/portage/env/compiler-clang-lto
| Code: | CFLAGS="${CFLAGS} -flto=thin"
CXXFLAGS="${CXXFLAGS} -flto=thin"
# -O2 in LDFLAGS refers to binary size optimization during linking, it is NOT related to the -O levels of the compiler
LDFLAGS="${LDFLAGS} -Wl,-O2 -Wl,--as-needed"
CC="clang"
CXX="clang++"
CPP="clang-cpp" # necessary for xorg-server and possibly other packages
AR="llvm-ar"
NM="llvm-nm"
RANLIB="llvm-ranlib" |
and have added
/etc/portage/package.env
sys-apps/less compiler-clang-lto
When I try to emerge it I get this | Code: | | clang: error: linker command failed with exit code 1 (use -v to see invocation) |
(Build log) https://paste.gentoo.zip/tTOdJgbS
This happens on any pakage Ive tried adding to /etc/portage/package.env
Any help would be greatly appreciated

| You need -fuse-ld=lld in *FLAGS or to set default-lld on clang-common. |
