Mangohud fails to build under LLVM profiles; with Clang, it's due to what seems like libc++ and, for GCC, mangled symbols. Reproducible: Always Steps to Reproduce: 1. emerge mangohud::guru Actual Results: Package fails to emerge both with Clang and GCC Expected Results: Package to build with at least one compiler Portage

Created attachment 885089 [details] LLVM Build Log
Created attachment 885090 [details] GCC Build Log
@Neko-san That is a LD error in the linking stage, I don't know how to really solve it. Most probably is a bug upstream to solve I the full gcc toolchain, using ld.bfd instead of ld.lld. Bellow is my gcc-full.conf env, pls update for your make.conf settings: ``` COMMON_FLAGS="-march=native -O3 -pipe" CFLAGS="${COMMON_FLAGS}" CXXFLAGS="${COMMON_FLAGS}" LDFLAGS="-Wl,--as-needed" CC="gcc" CXX="g++" CPP="gcc -E" AR="ar" NM="nm" RANLIB="ranlib" LD=ld.bfd OBJCOPY="objcopy" ```
With some experimentation, it appears that `-fPIE` and `-pie` are the reason why with GCC. Not ideal, but removing those solves it. As for Clang, it's straight up a source code issue.
Strange I don’t use that COMMON_FLAGS and still have problems linking using the llvm linker
Using gcc as the compiler
I just tested mangohud-9999 using gcc (Gentoo 13.2.1_p20240113-r1 p12) with COMMON_FLAGS="-O3 -march=native -pipe -fno-plt" And not other setting and I had no issue emerging and installing. I will try llvm now.
Just tested with clang 17.0.6 (CC and CXX overrides), same flags as my previous message, no issues. I cannot build as soon as I use lld. This is most definitely an upstream issue.
Are you using stdlibc++ or libc++? On LLVM profiles, this is a big difference and that reflects in the Clang build log
(In reply to Neko-san from comment #9) > Are you using stdlibc++ or libc++? > On LLVM profiles, this is a big difference and that reflects in the Clang > build log Yes libc++ can get a big effect, for exemple even using the full gcc stack, obs-studio fail to compile in the LLVM profile (Bug 922163)
Okay I tried to build directly from source and got the same errors, it's an upstream issue. I opened a bug report in Github [1] please chime in if you can help. [1] https://github.com/flightlessmango/MangoHud/issues/1240
That's not the same Clang error associated with this issue but it's good to know regardless.
For now I did not even attempt using `libc++`, one thing at a time :P
@adel.ks@zegrapher.com I can try the patch and see if works with libc++
