GCC > 4.7

[Franco Selem]

As you can tell from line 1 in the following log, my gcc version is evidently greater than 
4.7. It's 4.8.1 But near the end it tells me that my GCC version needs to be greater than 4.7.

Can you please attach the config.log file?

Is the g++ binary of the same version (4.8.1)?

[Alberto Garcia]

Please provide the config.log file, or the output of this command:

gcc -x c++ -dM -E - < /dev/null | grep GNU

Thanks!
