make
sudo make install- GIT编译
PREFIX=/usr/local
PATH=$PREFIX/bin:$PATH
git clone https://github.com/mono/mono.git
cd mono
./autogen.sh --prefix=$PREFIX
make
make install兴冲冲的按照以上步骤，会发现根本没有办法编译。怎么回事？正确办法是：
cd mono/external/bdwgc
PREFIX=/usr/local
./autogen.sh --prefix=${PREFIX}
./configure
make
sudo make install
