Hi,
It sounds like you've installed a hardened profile system from a normal stage3 (non-hardened) tarball.
Did you donwload a tarball with "hardened" in the name??
Either way, it shouldn't damage your computer by removing it as long as you really are setup for a hardened profile.
Rich. |

Didnt know that there is a hardened tarbals...I thought a normal gentoo install then convert it using[url] http://www.gentoo.org/proj/en/hardened/selinux/selinux-handbook.xml?part=2[/url]

Switching profile to non hardened and use the 4.1.2 (the omitted one) to build a hardened compatible gcc. Switch back to hardened.
Or use a livecd and chroot into your system then build gcc or quickpkg the one on the livecd.
Always quickpkg before removing a package you think you need. Helps greatly in recovery.
PS: I see I'm a little late. |

What command do you use to remove Gcc?
From what you've told us, gcc-config is looking for the old 3.x gcc which should still be there.
does 'equery list gcc' show any gcc packages left installed[/code]? |

The original result was coming from emerge --depclean....which listed 2 gcc, and I just say ok clean up everything...it was not only gcc but with lots of other packages.But I have never succeeded removing 1 gcc version, if I have 2 of them in the box I always break it haha....
Thats why I asked it, but I was still a little rushy to "Enter"....but I am reinstalling the box now, may be its a good idea then I can improve some stuffs on it.
Thanks guys...really appreciate it

I'm sorry I didn't speak up earlier, I could have saved you some hassle. You were given ample warning you were headed for trouble. Here is how to interpret the signs.
| depclean wrote: | sys-devel/gcc
selected: 3.4.6-r2
protected: none
omitted: 4.1.2 |
"Selected" indicates the version(s) selected for removal. "Protected" and "omitted" show the version(s) depclean (really emerge) will leave installed.
| gcc-config -l wrote: | [1] i686-pc-linux-gnu-3.4.6 *
[2] i686-pc-linux-gnu-3.4.6-hardenednopie
[3] i686-pc-linux-gnu-3.4.6-hardenednopiessp
[4] i686-pc-linux-gnu-3.4.6-hardenednossp
[5] i686-pc-linux-gnu-3.4.6-vanilla |
Take note of your current (at the time) selected compiler, denoted by the asterisk (*). Notice the version matches the "selected" version reported by depclean.
Interpretation: Proceeding with depclean will break your Gentoo. As you discovered.
Also, richard.scott indirectly warned you to keep gcc-3.4.6: | Quote: | | Ah, that'll be why you have gcc-4.x installed then... a hardened profile is restricted to gcc-3.x |
gcc-4 would not have been present had you installed from a hardened stage tarball. Thus, the later version was the one to remove.
depclean selects versions to clean based on version numbers, slots and masking. Some situations, like this one, require you to decide whether depclean wants to do something stupid--like remove the active C compiler (and only supported one for your profile).
Hope this helps you avoid getting burned in the future.

Ok this is now obvios that depclean wanna do the same crap for the 2nd time...this one I am suppose to really take all precautions, as the server is localted totally in different continent then where I am ...so screwing up gcc will make me pay lots of money to travel to get down there and reinstall the system
So how to get rid of that 4.1.2 without corrupting 3.4.6....??
P:S
The only way I can fully trust this is to test it on my VirtualBox and see with my own eyes ... 
for now I took a break from this server until I am pretty sure that I wont break it this time...
Edit:
I have the same situation on my VB...nice emulation 
Edit:
Ok tested against my VB...its perfectly safe ..oooosah

I'm interested to know which document you've read that tells you to remove the unwated GCC?
There's no harm (other than disk space being used up) to leave it there AFAIK.

No document ofcoz...but its pretty logic if you have 4.1.2 (from stage3) ...and then you have 3xx...emerge --depclean will try to remove the old version....whereby in this case is a hardened profile....so no choice 4.1.2 has to be removed as its blocking me from using depclean....otherwise I have to remove every package manually then why do I have depclean for... 
...cheers
