rustup fails with `fatal: libgcc_s.so.1: open failed: No such file or directory` on Sun 10 about rustup HOT 3 CLOSED

@shanebishop Thanks a lot for filing this issue!

As you've already found out, according to our current target policy, Solaris 10 is not supported by the Rust project as a whole (i.e. neither as a host nor as a target), so even if Rustup happens to work, there will be no officially distributed rustc and other components, thus it's out of our project's scope to make it possible for a Solaris 10 machine to be used as a compilation host.

If you would like to run Rust programs on such a machine, I personally recommend using the "custom target" feature on a supported host platform, and then find a way to cross-compile for the target in question.

Thanks a lot for your comprehension, and have a nice day!

Thanks @rami3l.

In that case, are there instructions somewhere on how to build rustc from source?

@shanebishop Here are some links that might be relevant to your custom target cross-compilation usage:

• https://docs.rust-embedded.org/embedonomicon/custom-target.html for defining a new custom target;
• https://doc.rust-lang.org/nightly/rustc/platform-support/mipsel-sony-psx.html for being able to use std and friends with build-std.

OTOH compiling rustc itself would be a more involved process, I suggest you make a new post on the Zulip server (https://rust-lang.zulipchat.com) if that's what you need.
