Nixpkgs: [Guix] msbuild outdated mono dependencies?

Created on 27 Feb 2020 · 8Comments · Source: NixOS/nixpkgs

I'm trying to package msbuild (the build tool for Mono) for Guix and I essentially copied all the Nix definitions to Guix. It really helped getting started, so thank you Nix! :)

Now I have a Guix definition that should be ready (https://gitlab.com/nonguix/nonguix/-/blob/wip-mono/nongnu/packages/mono.scm#L348) but it fails at the build stage with

Some command line switches were read from the auto-response file "MSBuild.rsp". To disable this file, use the "-noAutoResponse" switch.

...

And many more complaints like this that the packages are outdated.

Looking at https://github.com/mono/msbuild/blob/xplat-master/eng/Packages.props, it seems true that the versions don't match those used by Nix here:
https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/tools/build-managers/msbuild/nuget.nix

So how does Nix manage to build msbuild then?
Any idea?

Thanks in advance.

Oh, just got it: The nuget.nix file defines multiple versions for many deps, e.g.
system.reflection.metadata version 1.4.2 and 1.6.0 are defined.

I'll try again later then.

I assume that Nuget is capable of registering multiple versions, correct?

I managed to build msbuild. However, when trying to package a simple library like https://github.com/protobuf-net/protobuf-net, it fails with:

I'd like to highlight a few things here:

The warning

/tmp/guix-build-protobuf-net-2.4.5-1.706684b.drv-0/source/src/protobuf-net/protobuf-net.csproj : warning MSB4242: The SDK resolver "Microsoft.DotNet.MSBuildSdkResolver" failed to run. hostfxr assembly:<unknown assembly> type:<unknown type> member:(null)

echoes this line in the Nix package:
ln -s $(find ${dotnet-sdk} -name libhostfxr.so) artifacts/mono-msbuild/SdkResolvers/Microsoft.DotNet.MSBuildSdkResolver/.
While the symlink is set at runtime, it's not present in the final package. Are we supposed to include it?

First error is

Seems that Nuget needs to run, but maybe fails because of the lack of network. Any clue what to do about this?
It seems to be trying to build Debug/net461, so maybe if I somehow provided this as input it would not try to build it.

Another error which stands out is

The RuntimeIdentifierGraph.json file is in the source but is not included in the final package. Any clue why?

Is your question still relavant @Ambrevar? You didn't get much help and now I have a problem with msbuild too. It seems the provided mono contains msbuild 14 instead of msbuild 15.

Yes, I'm still stuck with msbuild. I haven't tried a different version yet.
My guess is that I need to give a proper read to the msbuild documentation to understand what it requires to run properly.

On gitter's #mono channel, someone recommended to either use the packages that were built for other distributions or to follow Debian's recipe to build the .deb files.

Hello, I'm a bot and I thank you in the name of the community for opening this issue.

To help our human contributors focus on the most-relevant reports, I check up on old issues to see if they're still relevant. This issue has had no activity for 180 days, and so I marked it as stale, but you can rest assured it will never be closed by a non-human.

The community would appreciate your effort in checking if the issue is still valid. If it isn't, please close it.

If the issue persists, and you'd like to remove the stale label, you simply need to leave a comment. Your comment can be as simple as "still important to me". If you'd like it to get more attention, you can ask for help by searching for maintainers and people that previously touched related code and @ mention them in a comment. You can use Git blame or GitHub's web interface on the relevant files to find them.

Lastly, you can always ask for help at our Discourse Forum or at #nixos' IRC channel.
