Method 1:

Install gcc4.4 and galleys 4.4

The code is as follows:

Modify the version with default gcc and Gmail + of 4.4

Sudo update-alternatives-config gcc

Sudo update-alternatives-- config gathers +

Method 2:

First of all, take a look at which versions of your Debian are installed with the gcc command: ls / usr/bin/gcc*-l my display is

The code is as follows:

Lrwxrwxrwx 1 root root 7 2011-08-14 15:17 / usr/bin/gcc-> gcc-4.7

-rwxr-xr-x 1 root root 224544 2011-10-06 05:47 / usr/bin/gcc-4.4

-rwxr-xr-x 1 root root 237072 2011-09-17 17:25 / usr/bin/gcc-4.5

-rwxr-xr-x 1 root root 302104 2011-09-17 05:43 / usr/bin/gcc-4.6

From the above, you can see that the default installation is gcc-4.7, now change it to gcc-4.4

Delete the soft connection file / usr/bin/gcc for gcc-4.7. (just delete the soft connection)

Command: sudo rm / usr/bin/gcc

Then make a soft connection and point to gcc-4.4.

Command: sudo ln-s / usr/bin/gcc-4.4 / usr/bin/gcc
