Mac APE installation error >> configure: error: installation or configuration: C compiler cannot create executables

Question

I am installing APE (Ajax Push Engine) on my MAC. But it is giving me an error during installation,

configure: error: installation or configuration problem: C compiler cannot create executables. 

I have gcc installed on my machine: gcc -v gives 'gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00)'

How can I remove this error?

Answer 1

As Mat said, check the config.log. I had a similar issue while building SpiderMonkey on ML, and the error turned out to be to do with the configure expecting the C-compiler executables to be called gcc-4.2 and g++-4.2 which is not the case in OSX, they are called gcc and g++ instead.

To fix the problem I did:

$ export CC=gcc
$ export CXX=g++
$ ./configure

This way it worked and succeeded. Thanks to Mat.
