[Insight-users] building error : CC and CXX must be set before running ccmake.

[Luis Ibanez]

Hi Bing,


Thanks for sending your CMakeCache.txt file.

Here is the source of your problem:

    //C++ compiler
    CMAKE_CXX_COMPILER:STRING=c++

You are invoking "c++" as the C++ compiler. This
is not bad in itself, the problem is that the same
is later used as the C++ linker.

You should be using "g++" instead of "c++".

Before running "ccmake", please set the CC and CXX
environment variables like:

    export CC=/usr/bin/gcc
    export CXX=/usr/bin/g++

or

    setenv CC  /usr/bin/gcc
    setenv CXX /usr/bin/g++

depending on the shell that you are using.


Please wipe out the binary directory
before you do this configuration.


Regards,


   Luis
