hi... a basic question. fc6 comes with gc4.1 . i'm looking to test gc4.2, and would like to have a parallel dev environment so i have both 4.1 and 4.2. i'm trying to find pointers on what needs to be done, to make sure i don't screw up the current 4.1 environment. it appears that all i need to do is to set a prefix dir when i do the initial configure. --./configure --prefix=/gcc42 --make --make install this appears to place everything under the gcc42 top level dir. however, what will i need to do to actually be able to hook into the libs/objs created by the gcc4.2 build. what will i have to insert into my paths, or rather where should the information be placed.. in the bashrc/profile files/etc...
The standard way in this case is to follow the supplier's advice:FSF in this case. It should install to /usr/local, well out of your way and defined by standards to be used this way.
pointers/sites on this would be helpful. haven't been able to find a good site that walks through this... once i test 4.2, i'll just rebuild, and rewrite gcc4.1. are there any issues that i'm going to run into when i do that!
If the versions are in different locations, there is no problem at all. You'd choose the one you want by setting PATH appropriately.
You could even contemplate a virtual machine just for the occasion: over there, across the room, I have a 64-bit system running F8T3 for just this sort of thing.
