I am using the latest master (Last commit - https://github.com/OmniSharp/omnisharp-roslyn/commit/e8507177962cda27804f930dc58bce090f910c75) . I followed the steps as listed to build omnisharp-roslyn and on running ./build.sh, I get the error:

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
=================================================================

Error: One or more errors occurred.
	GitVersion: Process returned an error (exit code 134).

Please help.

I managed to get GitVersion working using techniques described here:

Install libgit2, which on my system is done with
```
sudo pacman -S libgit2
```

Edit tools/gitversion.commandline.4.0.0-beta0012/GitVersion.CommandLine/tools/LibGit2Sharp.dll.config to point to the installed libgit2.so

<configuration>
    <dllmap os="linux" cpu="x86-64" wordsize="64" dll="git2-baa87df" target="/usr/lib/libgit2.so" />
    <dllmap os="osx" cpu="x86,x86-64" dll="git2-baa87df" target="lib/osx/libgit2-baa87df.dylib" />
</configuration>

I suspect that a build on Ubuntu would now have worked, but on Arch there is no Version, so I had to change build.cake#L51 to the following (added the ? to make Version nullable):

        var version = platform.Version?.ToString();

Following that, I can build! I need the --use-global-dotnet-sdk flag, or the .dotnet/dotnet-install.sh script errors out (again because archlinux uses rolling releases and has no version):

./build.sh --target Quick --verbosity Verbose --use-global-dotnet-sdk

Success!

I just created a VM and can reproduce the problem. It looks like this is due to https://github.com/GitTools/GitVersion/issues/1408. There are various solutions we could employ to workaround the problem, but I think we should probably just wait until GitVersion is fixed.

“There are various solutions we could employ to workaround the problem” – could you please provide one or some of them? This would get me past this issue. Thanks.

I have not investigated deeply enough to find any workarounds. @david-driscoll, do you have any ideas? It feels like GitVersion is dropping the ball on Linux.

DustinCampbell on Aug 14, 2018

@DustinCampbell could you provide @hifall and I some possible workarounds? I’ve updated to the most recent master branch and it seems that this issue with GitVersion has yet to be fixed because I’m getting the same error.

I could resolve DllNotFoundException by installing libcurl3 by apt-get, but another problem is occured. downloading dotnet-runtime-1.1.2 was failured because it was not supported in ubuntu-18.04. Here is error message.
