It tries to compile and link rustc via bootstrap rustc and gcc, via a i686 compiler (also on x86_64). What the error message means is that it is only picking up the x86_64 glibc - and not the i686 glibc - even though the "cc" command line contains "-m32". I've even added a custom linker command to the rust config (also in the patch) but that doesn't help either - apparently that setting is not even picked up. Maybe that's the reason... Rust has support for Nix somewhat, and I've enabled it in the bootstrapper. I've also added cross-libc for i686 and fixed up environment variables (in a hacky way - maybe that's the reason). So I guess my actual question is how to do this cross compilation correctly. Note that the rust bootstrap compiler are binaries from upstream. (There's a project "mrust" that is a reimplementation of Rust in C++ that we could use in the long term in order to remove this binary) ----------------------------------------------------------
