安装 OpenMPI：C C++ 编译器不 link 兼容
Install OpenMPI: C C++ Compilers not link compatible
我正在我的 Amazon EC2 服务器上安装 Open MPI。安装最新的 gcc-7.3 编译器后，我尝试从他们的官方网站安装 openmpi-3.0.1。
这是我输入的代码：
wget "https://www.open-mpi.org/software/ompi/v3.0/downloads/openmpi-3.0.1.tar.gz"
tar -xvf openmpi-3.0.1.tar.gz
cd openmpi-3.0.1
./configure --prefix="/home/ubuntu/.openmpi"
按照此处的说明指南进行操作http://lsi.ugr.es/jmantas/pdp/ayuda/datos/instalaciones/Install_OpenMPI_en.pdf
结果说 C 和 C++ 编译器不 link 兼容（见图）
问题已修改。首先，按照@Gilles Gouaillardet 的想法，如果我输入 dpkg --list | grep compiler，它会显示
ii g++ 4:5.3.1-1ubuntu1
amd64 GNU C++ compiler
ii g++-5 5.5.0-12ubuntu1~16.04
amd64 GNU C++ compiler
i gcc 4:5.3.1-1ubuntu1
amd64 GNU C compiler
ii gcc-5 5.5.0-12ubuntu1~16.04

ii gcc-5-multilib 5.5.0-12ubuntu1~16.04
amd64 GNU C compiler (multilib support)
ii gcc-7 7.3.0-16ubuntu3~16.04.1
amd64 GNU C compiler
ii gcc-multilib 4:5.3.1-1ubuntu1
amd64 GNU C compiler (multilib files)
ii gfortran-7 7.3.0-16ubuntu3~16.04.1
amd64 GNU Fortran compiler
ii libecj-java 3.10.1-2ubuntu1

ii libllvm5.0:amd64 1:5.0-3~16.04.1
amd64 Modular compiler and toolchain technologies, runtime library
ii libxkbcommon0:amd64 0.5.0-1ubuntu2

其次，这里是config.log@Zulan的建议

generated by GNU Autoconf 2.69. Invocation command line was

如果你想使用 GNU 7 编译器，你首先必须安装 g++-7，然后告诉 Open MPI 使用它们
./configure --prefix=/home/ubuntu/.openmpi CC=gcc-7 CXX=g++-7 FC=gfortran-7
