Actually, I do not know what "ICE" means.

Can anyone tell me about that? I had google it but got nothing. :)

philberty commented 3 years ago

ICE means "internal compiler error" which could be a variety of reasons from crash or an assertion was hit.

It would be interesting to see what the errors are here, there should be a gccrs-build/gcc/testsuite/rust/rust.log to find more information.

philberty commented 3 years ago

I think we could spin a github automation for this for free.

philberty commented 3 years ago

Since they are all execute tests it could be some configuration thing.

Got it. Then this is not a ICE issue, LOL. Let me change the title.

thomasyonug commented 3 years ago

Thanks @philberty , I see the rust.log. It's my env issue about ld.

philberty commented 3 years ago

I think it still thinks it's valuable to keep this issue open until the issue is resolved. Was there a fix you were able to do?

thomasyonug commented 3 years ago

I'm trying to reconfigure the project for macos. It seems like I miss some flag about the library location. The root cause of all these errors is gccrs cannot find the libSystem.B.dylib.

Here is the verbose about gccrs ./xx.rs -B ./gcc/

I think I got it.

../gccrs/configure --prefix=$HOME/gccrs-install --disable-bootstrap --enable-multilib --enable-languages=rust --with-native-system-header-dir=/usr/include --with-sysroot=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk

Configure project with above command can solve this issue. Should we change the README with a mac version building command?

philberty commented 3 years ago

Nice detective work :D, yes please if you create a PR to update the README you can link against this issue the PR can close this issue at the same time.
