What distro are you using? Most distros ship with multiple GCC versions. Eg. Debian 5.0.8 (old stable) comes with 2.95, 3.2, 3.4, 4.1. 4.2 and 4.3. The latest 6.x also includes 4.4. You just have to apt-get install gcc-4.3 and ensure symlink /usr/bin/gcc points to /usr/bin/gcc-4.3. To make the changes only to your user account, "export CC=gcc-4.3" before calling make. Or you can also create a the above symlink in ~/bin/gcc pointing and ensure PATH is set to ~/bin first. > what are the changes to include paths , macros , flags libs when i upgrade to > gcc 4.4.4 or in simple what changes i should do in my makefile or > application when i migrate to newer version of gcc . You don't have to change anything in your Makefile to use a new version of gcc. You will reuse the same system libraries with the new compiler as well. Unless your app is using features which are tied to a specific gcc release, the migration to a new compiler is seamless. If you want to use new features available in gcc 4.4, then consult the manuals. - Raja _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
