SkiaSharp build on linux error

[zhangevanone]

Hi dear,
When I running bootstrapper.sh -t anything going to MSBuild, I got follow errors. Anyone to help me?
Thanks!

NuGet Version: 4.1.0.2450
MSBuild auto-detection: using msbuild version '14.0' from '/usr/lib/mono/xbuild/14.0/bin'. Use option -MSBuildVersion to force nuget to use a specific version of MSBuild.

The new build requirement is MSBuild 15.

If you are running a relatively new version of Linux, our native library may work for you:

• (Release Notes) https://github.com/mono/SkiaSharp/releases/tag/v1.59.1
• (CI Build) https://jenkins.mono-project.com/view/Components/job/Components-SkiaSharp-Linux/51

In addition, you can also try out @kekekeks 's builds on NuGet:

• https://preview.nuget.org/packages/Avalonia.Skia.Linux.Natives/

[zhangevanone]

My running environment: Ubuntu 16.04.1 For X64, Mono's version 5.0.1.1 and SkiaSharp is v1.59.1, how can I using MSBuild 15 going todo. Thanks!

[kekekeks]

@mattleibow Could you please switch your build agent to use Ubuntu 14.04? Also, please link libstdc++ statically. That should cover most of the distros.

[mattleibow]

@kekekeks The build agent should be 14.04 already. And will linking libstdc++ statically cause any issue with dynamic bits? I may be confused, but some people (on the internet) say that if I link statically then we can't use dlopen (which is used for the GL bits). Or, is this just for libgcc?

[kekekeks]

You need to build libstdc++ with -fvisibility=hidden, so it won't cause conflicts.

[kekekeks]

See more information about the issues there: https://github.com/phusion/holy-build-box/blob/master/LINKING-CXX.md

See libstdc++ compilation flags here: https://github.com/phusion/holy-build-box/blob/master/image/build.sh#L357
