Linker errors on using C compilers apart from zig cc
#10

Would it be possible to remove the dependency on compiler_rt? |
|
@Shinyzenith to my knowledge "compiler_rt" is necessary for Zig, executables just happen to automatically build it in while it doesn't when you build a library. You should be able to add '-fcompiler_rt' to zig build in order to resolve those symbols |
|
Ok, I tried |
|
Edited the build.zig to add |
See What is your minimal c program and what is your target system? |
Hi!
First of all, this is a really cool project and I'd love to contribute!
(Commit hash of ziglibc: d6b6959)
I was wondering if it'd be possible to make ziglibc work in contexts outside of zig such as with clang or any system
$CC?Currently on attempting to link with
clangI get the following linker errors:clang -nostdlib -I ../../inc/libc -I ../../inc/posix/ -I ../../inc/linux/ -L. -static -lstart -lcguana main.c/usr/bin/ld:

Naturally I assumed the above errors with clang introduced due to not linking with compiler_rt and attempted to compile a simple hello world
main.cintomain.oand then used a zig compiled libcompiler_rt.o file and it indeed reduced my errors with clang significantly to the following:EDIT:
After some experimentation, linking with
libcompiler_rt.ausing-fuse-ld=lld/-fuse-ld=moldwhile using the above command fixes the issues but I'm still intrigued as to why that's the case.The text was updated successfully, but these errors were encountered:
