https://github.com/gcc-mirror/gcc/blob/c18c53db823b22204405e015cbb4d7b039f875c0/gcc/rust/Make-lang.in#L57 I removed -ldl -lpthread in make-lang.in and it compiles. It isn't very clear. I did not enable rust languages in the configure since I do not use rust at all, but why does the grust settings still impact on GCC build? ________________________________ From: pifminns deettnta <tstndeemkssz@xxxxxxxxxxx> Sent: Monday, August 5, 2024 01:22 To: gcc-help@xxxxxxx <gcc-help@xxxxxxx> Subject: Re: Why does gcc build try to link lpthreads and ldl for x86_64-w64-mingw32 host? https://github.com/gcc-mirror/gcc/blob/c18c53db823b22204405e015cbb4d7b039f875c0/configure.ac#L2040C1-L2041C37 I think this is where it is wrong.
