I think you are right that gcc and g++ are two different versions on this
machine.:
$ gcc -dumpversion
4.8.0
$ g++ -dumpversion
4.2.1
$ which gcc
/usr/local/Cellar/gcc48/4.8.0/bin/gcc
$ which g++
/usr/bin/g++
Also when I did as suggested by Sebastian:
$ echo $CXXFLAGS
Nothing returned
I didn't know why this was happening. I have just installed the latest
version of gcc4.8,and thought it should have all the C++0x and C++11
features.
How can I fix this up? Can you please help me with this? Thanks a lot
Austen
