我尝试使用命令在Debian 9.3上编译mono
apt-get install git autoconf libtool automake build-essential gettext cmake python
cd /usr/local/src
wget https://github.com/mono/mono/archive/mono-5.18.1.0.tar.gz
tar -xvf mono-5.18.1.0.tar.gz
cd mono-mono-5.18.1.0
./autogen.sh --prefix=/opt/m518
./configure --prefix=/opt/m518
make
但是会抛出奇怪的错误
...

如何解决这个问题，以便单声道可以编译？
/usr/local/src/mono-mono-5.18.1.0/external/boringssl目录为空。
更新
我按照答案中的描述编译了Mono。 MVC应用程序无法启动。 Apache errorlog包含找不到string.split的错误（下面的完整错误）。如何解决这个问题，以便应用程序可以运行。
