配置：错误：C编译器无法创建可执行文件（OSX El Capitan）

Question

I'm trying to install some software on my Mac (OS X El Capitan 10.11) and when running its configure script, I'm getting a message that it cannot create executables. I'm passing:

../configure \
--disable-diablo \
--download-essential  \
CC=/usr/local/bin/mpicc  \
CXX=/usr/local/bin/mpicxx  \
F77=/usr/local/bin/mpif77  \
FC=/usr/local/bin/mpif90  \

from a build directory. I had to specify where the compilers are located as it would also return an error if I didn't. Also, I am very new to this material so I would like to ask for a bit of patience if I take a while to understand whatever help is sent my way.

Also, I'm having trouble posting my config.log, so help with that would be appreciated as well.

Answer 1

This error usually means that the compiler failes a simple test of compiling a test code and running the resulting binary. You are trying to use mpicc to compile your project (is it necessary?) and it is only a wrapper for regular compiler, You have to have gcc or clang already in the system.

The easiest way to get all "Command line tools" including clang for macOS is to just install XCode and follow with xcode-select --install in terminal.
