I was wondering if it is possible to do away with gcc 3.3.5. I think

I read something in a post about overriding gcc version used to
compile the kernel and maybe it had to do with some make.conf flag. I
spent some time googling, searching gentoo forums (cannot seem to
search for version numbers there) and gentoo wiki but I havent turned
up much. Surely my searching skills have gone bad, I cannot imagine
being the first to ask this question. What I am asking is:
0. Is there a HOWTO that I have blatantly missed?
1. Does the kernel compile with gcc and is it stable?
2. Is there a gentoo way to override compiler version used for the
kernel compilation. If not but it is perfectly ok to compile the
kernel with gcc 3.4 how does one get the kernel compile system to use
particular gcc version?
3. Are there other packages that override the default gcc, maybe
like ?
Thanks,
Eugene.
Hi,
GCC is slotted so you can have both 3.3.5 & 3.4.3 (i have them too).
See gcc-config package which is a dependency of GCC-any-version.
Just run 'gcc-config -l' in order to list/see all available versions,
"gcc-config -c' outputs the active one (gcc-config --help). To change
the active gcc use: "gcc-config 1|2|3|..6| ..9 depending on how many gcc
versions/sub-vers. are there.
Didn't had any problems with both 3.3.5&3.4.3, IIRC there are some new
CFLAGS in gcc-3.4.X (mtune ?) which could be put in 'make.conf' but
overly there're no problems with any of them.
For about half an year 3.4.x is stable for me (kernel too).
HTH. Rumen
Thanks, I made a mistake. I do have gcc 3.4.3 set as default and it is
being used to compile the kernel. When I checked which compiler was
being used during the kernel compile I ssh'ed into a gcc 3.3.5 machine
to test it so I thought it was switching back to 3.3.5... Tragic really. :)
Eugene.
