Whatever is installed on your system doesn't change unless you uninstall the packages.

Is that true? \-- When building a gcc compiler, there are dependency packages. The development/release cycle of these dependent packages is independent of each other. So, not all releases will be able to produce a compiler for you.

I was trying to identify which are these dependent packages. glibc seems to be one. binutils too is perhaps sensitive to gcc/glibc version. Are there any other packages I should be specifically worried about? Syam ___ Fedora-india mailing list Fedora-india@redhat.com https://www.redhat.com/mailman/listinfo/fedora-india
