confliction between gcc 3.4.6 and gcc 4.1.2

[mostafa_dv]

Hi
I am making porting from gcc 3.4.6 to gcc 4.1.2 but there are alot of problems as while i am building an executable it uses libraries of the old gcc (3.4.6) so the executable crashes as it built by mixing 2 versions of gcc. I removed the old gcc (3.4.6) but the problem didn't solved so how can i be sure that all the libraries used in the building are for the new gcc (4.1.2)
i.e how can i be sure that the old gcc is completly removed and all the libraries that it was using.

Thanks

The GCC toolchain is designed so that you can have multiple versions of GCC on the system at once. In my case I have 3.4, 4.1, and 4.4 installed and use them as required. So, removing 3.4 did not likely help. To migrate an application from 3.4 to 4.x, you will need to recompile all of your sources, including any shared or static libraries that are not part of the standard system. You will need to review your Makefiles to be sure that it is linking to generic library versions, such as -l xyz and not -l libxyz.so.8.0. And finally, you may need to make some code changes, or specify some compiler/linker flags to support deprecated constructs since 4.x is much more standards-compliant than 2.95 or 3.4.x. In effect, this is a platform port. Treat it as such.
