I also had the same issue on Alpine. Here's a workaround you can do:
odin build your_dir -reloc-mode:pic -build-mode:obj
clang -fPIE your_dir.o -o your_executable
I have no idea why it's trying to link -lgcc
.
git bisect
pointed me to d1a1e8f646c5b959be638aa955856f686b11a4f3
as the first faulty commit. Updating to LLVM 18.1.6 did not resolve this issue. Don't see where it tries to link -lgcc
either.
I can't replicate it on Ubuntu 24.04. For LLVM 18:

LLVM 17 either:

It can be temporarily fixed by specifying your target triple here. On my setup it's x86_64-alpine-linux-musl
, so it should look like this:
bc->link_flags = concatenate3_strings(permanent_allocator(),
str_lit("-target "), str_lit("x86_64-alpine-linux-musl"), str_lit(" "));
Tried to compile ols
with it, works fine. Can't really come up with a better solution yet, as I'm not very familiar with the codebase.
Thanks. I can confirm that this temporary fix works.
@laytan Seeing as you have worked on this part of the codebase before, do you know how we could make a more permanent fix to this issue?
From the temporary fix it seems like using the -gnu
suffixed targets makes it link in gcc?
Maybe this line needs changing: https://github.com/odin-lang/Odin/blob/d99e1616cf0199895ede2a82490197a9e5ccebd9/src/build_settings.cpp#L968
Something like x86_64-pc-linux-elf
instead?
But these are just initial guesses, I will try to find some time to test/reproduce this
Problem
./build_odin.sh
succeeds on dev-2024-04a and prints the demo../build_odin.sh
fails on dev-2024-05 with the following output:Somewhere between dev-2024-04a and dev-2024-05 an issue was introduced, or have the build requirements changed?
