Hello. I tried to compile a program (plugger), but I don't have *any* sort of compiler installed. This is on Cent5.3. So, I used Package Manager, concentrating on gcc. But, it seems that I have a choice, thus: gcc-4.1.2-46.el5.i386 gcc-4.1.2-46.el5_4.1.i386 gcc-4.1.2-46.el5_4.2.i386 gcc-c++-4.1.2-46.el5.i386 gcc-c++-4.1.2-46.el5_4.1.i386 gcc-c++-4.1.2-46.el5_4.2.i386 ... along with some others (Fortran, Ada, Java, and Obj-C). I'm thinking that I need only 1 'flavor' (say, gcc-4.1.2-46.el5.i386 and gcc-c++-4.1.2-46.el5.i386) - correct? I tried a google.com/linux search - the only link that seemed helpful was http://gcc.gnu.org/ -- where I found only this: "The core distribution includes the C language front end as well as the shared components." I have no clue which package would be the FE, and what the shared components are. Perhaps 1 of those packages is the core?
