 Posted: Mon May 02, 2016 6:21 am Post subject: GCC no more installed-[SOLVED] |
 |
|
Dear,
I uninstalled GCC by mistake.
My fault !
Now, I get :
gcc-config -l
* gcc-config: Active gcc profile is invalid!
emerge --info
!!! No gcc found. You probably need to 'source /etc/profile'
!!! to update the environment of this terminal and possibly
!!! other terminals also.
Which procedure to follow to install it again?
Thank

Do you have another Gentoo machine available?
If so you want to build gcc on that machine with the binary package option set (-B) and then copy the binary gcc package onto your broken machine (-k) and emerge the binary package. It will be put in the /usr/portage/packages directory
If you don't, my recommendation would be to make a gentoo chroot. Just download and untar a fresh stage3 in an empty directory and use that to build your binary package. Do NOT overwrite your current root as that will make it worse. You can bind the /usr/portage directory between the host and chroot to save syncing and save the trouble of copying the package.

you can use a livecd, mount your root on it and
PKGDIR="/mnt/gentoo/usr/portage/packages" quickpkg gcc
it will create a binary of the livecd gcc.
now chroot and ask portage to install that version (using -B option), if any deps are needed, grab them from another shell the same way (PKGDIR=...) |

good question Buffon 
now that you ask, i doubt, gcc might comes from the stage3 file, been a long time i didn't use any. |

Dear,
Thank a lot for your advices.
I tried several time but I'm not able to compile GCC in the CHROOT.
I also take several binary GCC on "tinderbox.dev.gentoo.org" and untar on my root, but it says Invalid profile after I select it "gcc-config 1"
| Code: | gcc-config -l
* gcc-config: Active gcc profile is invalid!
[1] i486-pc-linux-gnu-4.8.3
|
My system Hard disk is like this :
SDA1 = /boot (grub) --> I don't need to mount this partition.
SDA2 = SWAP
SDA3 = root + usr
SDA4 = Extended
SDA 5 + SDA6 = Home --> I don't need this partition
So, I think I just need the SDA3 in the CHROOT
This is what I have realized :
Boot with the “Minimal boot CD” (last version).
Mount the broken install :
• mount /dev/sda3 /mnt/gentoo
Create a folder for the Chroot which will be used for emerge packages.
• mkdir /mnt/gentoo/home/rescue
Untar stage 3 which is on the Hard Dik root :
• cd /mnt/gentoo
Remark : it's the stage 3 I used to realize my system "stage3-i686-hardened-20151020.tar.bz2"
It's a "hardened" I don't remember why. Is it important to take a similar and how can I check I have a hardened system or profile?

Mount bind portage :

• mount -o bind /mnt/gentoo/usr/portage /mnt/gentoo/home/rescue/usr/portage
copy :
• cp -r /mnt/gentoo/etc/portage/* /mnt/gentoo/home/rescue/etc/portage
Chroot :
• chroot /mnt/gentoo/home/rescue
• source /etc/profile
• env-update
Change make.conf so portage will create binary packages
FEATURES="buildpkg"
• Emerge –buildpkgonly -av gcc
I didn't do it already, but next step would be :
Mount the broken system to /mnt/Gentoo
• mount /dev/sda3 /mnt/gentoo
• chroot /mnt/ gentoo
• source /etc/profile
• env-update
Emerge : emerge -k sys-devel/gcc

Hi,
You didn't posted an actual error.
Please post the results of
| Code: |
emerge --info '=sys-devel/gcc-4.9.3::Gentoo
emerge -pqv '=sys-devel/gcc-4.9.3::Gentoo
cat /var/tmp/portage/sys-devel/gcc-4.9.3/temp/build.log
|
as requested by the error message.
Thank you. |

esa,
Fix My Gentoo should work for you.
It describes how to rescue a system that won't boot. Its simpler if your system boots but you can use it as is if you prefer.

Dear,
Finally, I am able to compile the gcc 4.9.3.
I followed the same procedure but I downloaded the last stage 3 (in place of using my original stage3).
Maybe it wasn't the cause of the issue.
Thank for your help |

esa ... for the sake of completeness ... the issue here is that the previous 'profile' is gone, and you hadn't set it to the available profile (via 'gcc-config i486-pc-linux-gnu-4.8.3'). Doing so whould have resolved the issue (and saved you having to take the stage3 route).
Also, keeping a binpkg handy is ... well ... handy, 'quickpkg =sys-devel/gcc-4.9.3' will then allow you to 'emerge --usepkgonly sys-devel/gcc-4.9.3'.
best ... khay |
