一、编译coreclr
成功！
Repo successfully built.
Product binaries are available at /data/git/coreclr/bin/Product/Linux.x64.Debug
二、编译corefx
失败！15231个错误，编译结果如下：
/data/git/corefx/bin/obj/Linux.AnyCPU.Debug/Microsoft.CSharp/_AssemblyInfo.cs(3,11):

问题未找到解决方法，在GitHub上提交了Issue：#2073 。
更新：这是 corefx 的一个bug，后来被修复了。
三、编译dnx
失败！
第一次build的第1个错误：
Determining latest version
Latest version is 1.0.0-beta6-12082
Downloading dnx-mono.1.0.0-beta6-12082 from https://www.myget.org/F/aspnetvnext/api/v2
Installing to /root/.dnx/runtimes/dnx-mono.1.0.0-beta6-12082
dnvm needs unzip to proceed.
再次build的第1个错误：
dnx-mono.1.0.0-beta6-12082 already installed.
Cannot find dnx-mono.1.0.0-beta6-12082, do you need to run 'dnvm install 1.0.0-beta6-12082'?
这个错误是由于Ubuntu上没有安装unzip，通过下面的命令解决了问题：
apt-get unzip
dnvm upgrade -u
接下来的编译错误未找到解决方法：
warn: Dynamic view compilation failed.

在GitHub上提交了Issue：#2080 。
更新：删除dnx文件夹并重新git clone后问题解决。
rm -rf dnx/
git clone --recursive https://github.com/aspnet/dnx.git
cd dnx
./build.sh
