 Posted: Mon Dec 16, 2024 7:33 pm Post subject: [SOLVED] llvm, clang 19 fails to compile |
 |
|
all of the llvm-core and llvm-runtimes packages fails to compile on my system
llvm and clang are in path, tested for both 18 and 19 versions (19 compiled once with gcc, now it does not idk why, haven't changed a thing)
for context - this is a headless server
changing CFLAGS and other to default (as on the wiki) does not change a thing

Is x86_64-gentoo-linux-musl-clang in your PATH? Is it in PATH in the environment that portage is using when configuring a package?
What is your profile? Are you using an llvm one? |

Why are these absolute pathnames? The LLVM profiles set them to just "clang" and "clang++", where is this being overridden? /etc/portage/package.env?

This is an annoying issue. Your clang-19 toolchain is incomplete and cannot be used. You have to use clang-18 to finish compiling the -19 toolchain. It is doable with package.env.
That's my guess at least. |

In package.env, just tested in case it was a problem and just forgot to change really.
I recompiled all of the toolchain version 18
| Code: | | emerge -av llvm-core/llvm:18 |
, but still nothing, it seems that for some reason the compiler looks for x86_64-gentoo-linux-musl-clang instead of x86_64-pc-linux-musl-clang and ++ variants respectively, just did | Code: | ln -s x86_64-pc-linux-musl-clang x86_64-gentoo-linux-musl-clang
ln -s x86_64-pc-linux-musl-clang++ x86_64-gentoo-linux-musl-clang++ |
and it has compiled.
In /usr/lib/llvm/19/bin there is no x86_64-gentoo-linux-musl-clang and x86_64-gentoo-linux-musl-clang++ either. I wonder if it's to do with the ebuild.
It is also worth mentioning that today when I tinkered a bit with it I read in the log that I need to set CMAKE_CXX_COMPILER to an absolute path, so I did
| Code: | | export CMAKE_CXX_COMPILER="/usr/lib/llvm/18/bin/x86_64-pc-linux-musl-clang++" |
and it still was complaining about missing x86_64-gentoo-linux-musl-clang++. |

These also seem overridden / set elsewhere, amd64 musl profiles set CHOST to "x86_64-pc-linux-musl" and do not set CBUILD. This unusual triplet (quadruplet technically) was right in the thread's title and I didn't see it.
The instructions for migrating to 23.0 profiles also specified the removal of any assignment to CHOST in make.conf.

Oh, I haven't read those, but still I wonder why I stumbled upon this problem just now lol.
Now I know why on my desktop PC I have no CHOST in make.conf.
Marking as SOLVED. Thank You all for helping me out! |
