Rust library hashes

[Sandro Mani]

Hi

I'm packaging mingw-rust, and while everything compiled, the RPM build 
fails with

BuildError: The following noarch package built differently on different 
architectures: mingw32-rust-debuginfo-1.38.0-1.fc32.noarch.rpm
rpmdiff output was:
removed 
/usr/i686-w64-mingw32/lib/rustlib/i686-pc-windows-gnu/lib/std-667f9119009aea97.dll.debug
added 
/usr/i686-w64-mingw32/lib/rustlib/i686-pc-windows-gnu/lib/std-adb8e1a97c54d6f2.dll.debug
[etc]

So indeed I suppose the hashes used in the libraries vary depending on 
various factors, possibly the architecture of the host system. Anyone 
has an idea how to deal with this, or make the hashes stable between 
host arches?

Thanks
Sandro

Hi!

I don't have a solution for you, but I did see a similar difference when I
once experimented with building WebAssembly targets along with the main
rust toolchain. Something in the result seems to be including the host
information, and that should probably be fixed, but I'm not sure where that
is coming from.

Regarding mingw-rust, would you really want an entirely separate toolchain?
Or should we see about adding mingw targets as a subpackage of the main
rust.srpm? We would still need to solve this hash difference, but I'm
curious about your approach.

Thanks,
Josh
