Failure on maketest: c-dynamic-dylib

[retep998]

When running make check on Windows 8.1 x64 with MSYS2 using the 64-bit toolchain (also tested with external mingw-w64 toolchains and alternate msys tools), I get the following error:

Attempting to run the exe for that test in gdb results in a failure during startup.

I get the exact same issue on Win8 x64

My 64-bit build passes tests without any errors.
BTW, 0xc0000139 means "DLL Entry Point Not Found", i.e. a missing exported function in some dll. What happens if you just run bar.exe without gdb?

[retep998]

I think I figured out the issue. Apparently the problem was that my installed Rust was in the PATH, so if I removed that from my PATH, it worked just fine. Fortunately I installed it to a separate location so it was easy to do so, although if someone installed it without a custom prefix in msys2, it could be a bit tricky.

[oli-obk]

if you installed it without a custom prefix, make uninstall will do the job, too

[retep998]

I tried to do make check-stage1-std today, and it failed with a similar error and went away once I removed my existing Rust from my PATH.

[Diggsey]

I ran into this problem as well. Why is it looking in the path for rustc at all, it should know the exact path to the version of rustc currently being tested?

[bombless]

@Diggsey I think it's the dynamic linking part that makes it fail, not the rustc part.

[Marwes]

Still an issue and I could not get the workaround that retep998 posted to work.

[Diggsey]

edit:
Actually, this was caused by something else, ignore me.

This still happens even if there is no rust installation on PATH: I've reconfigured msys so that it doesn't inherit my windows environment variables, but I still get the exact same error:

I think this was fixed in #27553, so closing.
