Hi
These are the installed gcc/g++ on my system
$ ls -l /usr/bin/g++*
lrwxrwxrwx 1 root root????? 7 Mar 13? 2012 /usr/bin/g++ -> g++-4.6
-rwxr-xr-x 1 root root? 94808 Mar 16? 2006 /usr/bin/g++-3.4
lrwxrwxrwx 1 root root???? 52 Feb? 6 23:32 /usr/bin/g++-4.1 -> /opt/gcc-4.1.2/host-x86_64-unknown-linux-gnu/gcc/g++
-rwxr-xr-x 1 root root 263328 Apr 16? 2012 /usr/bin/g++-4.4
-rwxr-xr-x 1 root root 357312 Apr 16? 2012 /usr/bin/g++-4.6
The default g++ should point to g++-4.6, however:
$ which g++
/usr/local/bin/g++
$ g++ -v
Using built-in specs.
Target: x86_64-unknown-linux-gnu
Configured with: ./configure --disable-multilib
Thread model: posix
gcc version 4.1.2
How can I change the default g++ to 4.6?
Is it safe to create a symbolic link from /usr/local/bin/g++ to /usr/bin/g++ ?
Or there may be some libc incompatibilities?
?
Regards,
Mahmood
