这两天尝试在Mac/Linux/Windows三大平台上编译.NET跨平台三驾马车(coreclr/corefx/dnx)之一的corefx(.NET Core Framework),结果三个平台的编译都失败了。后来一一都解决了,在这篇博文中分享一下。
(一)
在Mac上编译corefx遇到的错误如下:
/git/dotnet/corefx/dir.props(214,5): warning : The Roslyn targets do not exist- Roslyn will not be used for this build, but the package should be restored if you build again. [/git/dotnet/corefx/src/dirs.proj] /git/dotnet/corefx/dir.props(214,5): warning : The Roslyn targets do not exist- Roslyn will not be used for this build, but the package should be restored if you build again. [/git/dotnet/corefx/src/Microsoft.CSharp/src/Microsoft.CSharp.csproj] /var/folders/c4/lf8cm6lx5178xsswpzfs2f_c0000gn/T/tmp257bf798c8da46a7baf3954722152b21.exec.cmd: line 3: /git/dotnet/corefx/packages/dnx-mono.1.0.0-beta5-11760/bin/dnu: Permission denied /git/dotnet/corefx/packages/Microsoft.DotNet.BuildTools.1.0.25-prerelease-00050/lib/packageresolve.targets(31,5): error MSB3073: The command ""/git/dotnet/corefx/packages/dnx-mono.1.0.0-beta5-11760/bin/dnu" restore --packages "/git/dotnet/corefx/packages" "/git/dotnet/corefx/src/Microsoft.CSharp/src/project.json"" exited with code 126. [/git/dotnet/corefx/src/Microsoft.CSharp/src/Microsoft.CSharp.csproj] ... 6 Warning(s) 5 Error(s)
删除corefx中packages文件夹重新编译,错误变成了:
System.IO.InvalidDataException: Unable to read package from path 'Microsoft.Net.ToolsetCompilers.1.0.0-rc3-20150510-01.nupkg'. ---> System.IO.FileFormatException: The specified archive is invalid. at System.IO.Packaging.Package.OpenCore (System.IO.Stream stream, FileMode packageMode, FileAccess packageAccess, Boolean ownsStream) <0x1055e4fd0 + 0x001df> in <filename unknown>:0
再次编译,又回到了之前的错误。
怀疑问题是Mac电脑与NuGet服务器之间的网络问题引起的,于是从另外一台Linux服务器上将corefx所需的所有packages下载下来之后,编译就取得了成功。
scp -r root@server:/git/corefx/packages/ /git/dotnet/corefx
./build.sh ... 1 Warning(s) 0 Error(s) Time Elapsed 00:07:33.93 Build Exit Code = 0
(二)
在Linux CentOS上编译corefx遇到的错误如下:
Restoring MSBuild... WARNING: Error: SendFailure (Error writing headers) WARNING: Error: SendFailure (Error writing headers) WARNING: The request timed out WARNING: Error: SendFailure (Error writing headers) Unable to find version '14.1.0.0-prerelease' of package 'Microsoft.Build.Mono.Debug'. Failed to restore MSBuild.
这个问题是由于没有在Linux上安装根证书,无法以https访问nuget服务器,运行下面的命令就可以解决问题:
mozroots --import --sync
(三)
在Windows上编译corefx遇到的错误如下(电脑上安装的是Visual Studio 2015):
corefxsrcCommonsrcSystemSR.cs(19,67): error CS0117: 'SR' does not contain a definition for 'ResourceType' [corefxsrcMicrosoft.CSharpsrcMicrosoft.CSharp.csproj] ...
这个问题比较怪,竟然是前段时间编译corefx时在bin文件夹生成的文件引起的,删除corefx中的bin文件夹,重新编译,问题就消失了。
