Hello, I'm using the IKVM 8.2.0 nuget and seeing an issue when trying to build a project that uses the IKVMReference tag on Linux. I've been able to reproduce on the following hosts:

Debian 11

dylan@debian11:~$ uname -a
Linux debian11 5.10.0-10-amd64 #1 SMP Debian 5.10.84-1 (2021-12-08) x86_64 GNU/Linux
dylan@debian11:~$ dotnet --version
6.0.101

Amazon Linux 2

[ec2-user@amzn2-dylan ~]$ uname -a
Linux amzn2-dylan 4.14.281-212.502.amzn2.x86_64 #1 SMP Thu May 26 09:52:17 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
[ec2-user@amzn2-dylan ~]$ dotnet --version
6.0.301

When I go to build I'm seeing this:

dylan@debian11:~/Downloads/IKVM-TikadotNet-Harness/Tikadot6$ dotnet build

It looks to be failing on line 403 of the IkvmCompilerLauncher when trying to load Mono.Unix. I've verified Mono is installed in both the environments I tested with however. Anyone else attempted building on a Linux host yet and had any success?

I don't believe the ikvmc compiler inside the NuGet package was intended for any other purpose than from <IkvmReference>. @wasabii - correct me if this is wrong.

The bin directory is missing the following DLLs that ikvmc depends on:

  • IKVM.Java.dll
  • IKVM.Runtime.dll
  • IKVM.Runtime.JNI.dll

The quick workaround for a build script would be to copy these 3 DLLs from the corresponding location in the lib directory for the target framework into the ikvmc directory you intend to use.

Alternatively, a stable place to download ikvmc from for build scripts is on the release page.

@wasabii - I realize this is most likely about preventing duplicates of IKVM.Java in the NuGet package to avoid bloating the package size. Could we use the AssemblyResolve event to make ikvmc probe for the missing dependencies in the lib folder so we don't have to have multiple copies of these DLLs in the package?

Looks like a native library isn't being loaded by the tool on Linux. Will check. Might have been left in the wrong place.

Nope. It's there. The story is that MSBuild tasks don't load the dep context properly, so still cannot resolve native libraries unassisted.

dotnet/msbuild#5037

Will have to load it by hand under the right circumstances it seems. Will have a patch shortly to test.

Oh. If anybody can figure out how else to make an executable in a NuGet package +x on extraction, let me know.

@wasabii Would running chmod +x work - something like this?

wasabii commented Jul 6, 2022

That's still a hack: that you have to write code to modify the extracted package at runtime is what I'm trying to avoid. The native library is no big deal.

If .nupkg's were tar files, for example, they would support simply marking the +x bit within the tar. But they're ZIP files. Which have no such standard mechanism.

Oh, @dylanlangston. You said this:

I've verified Mono is installed in both the environments I tested with however.

Mono isn't required. The issue is simply that it isn't loading a .so file in the NuGet package.
