Clang 6.0 Support for Linux

[mrkmg]

I am trying to test CoreRT on Arch Linux.

When I run dotnet publish -c Release -r linux-x64 I get:

.../microsoft.dotnet.ilcompiler/1.0.0-alpha-26405-01/build/Microsoft.NETCore.Native.Unix.props(100,5): error : Platform linker ('clang-3.9') not found. Try installing clang-3.9 or the appropriate package for your platform to resolve the problem...

I currently have clang 6.0 installed on my machine.

I agree that we need to have some kind of auto-detection for this.

In the meantime, you should be able to work around this by doing export CppCompilerAndLinker=clang-6.0. This will override the hard coded clang-3.9 default.

Now I am running into #5224.

Trying to follow the directions there to build my own version of llvm. I will report back what I find out.

+1 to this issue. Clang 3.9 simply isn't available on reasonably recent Fedora distributions (fc27, fc28). The earliest version available is Clang 4.0 through copr, which still isn't compatible with corert even with export CppCompilerAndLinker=clang-6.0

export CppCompilerAndLinker=clang

seems to work fine. why is the tool version-dependent by default?

Hitting this issue aswell. Using a recent clang version shouldn't be that difficult.
