从源代码构建 gcc 5.4.0 时出错

Question

I have to build gcc 5.4.0 from source on a server because I don't have root permission. The server is running on CentOS 6.5.

I try the following commands:

tar xzf gcc-5.4.0.tar.gz
cd gcc-5.4.0
./contrib/download_prerequisites
cd ..
mkdir objdir
cd objdir
$PWD/../gcc-5.4.0/configure --prefix=/ghome/mypath/software/try_gcc/installed/ --enable-languages=c,c++,fortran,go --disable-multilib
make
make install

一切正常，直到我运行

make

。我遇到了数百行错误消息，但我不知道发生了什么。部分错误信息如下：

unset LIBRARY_PATH CPATH C_INCLUDE_PATH PKG_CONFIG_PATH CPLUS_INCLUDE_PATH INCLUDE

在您的终端中运行此命令。你会得到它
