 Posted: Mon Jul 29, 2013 10:59 pm Post subject: [Solved] Gentoo installation from within Debian |
 |
|
I'm trying to install Gentoo amd64 from within Debian Jessie also amd64.
The problem is - I cannot compile anything inside chroot. There's always the same GCC error no matter what I try to emerge:
| Code: | checking for x86_64-pc-linux-gnu-gcc... (cached) ccache gcc
checking whether the C compiler works... no |
Is it because there's different gcc version in my Debian than in Gentoo?
Gentoo:
| Code: | # gcc-config -l
[1] x86_64-pc-linux-gnu-4.6.3 * |
Debian:
| Code: | # dpkg -l | grep gcc
ii gcc 4:4.7.2-1 amd64 GNU C compiler
ii gcc-4.7 4.7.3-4 amd64 GNU C compiler
ii gcc-4.7-base:amd64 4.7.3-4 amd64 GCC, the GNU Compiler Collection (base package)
ii gcc-4.7-plugin-dev 4.7.3-4 amd64 Files for GNU GCC plugin development.
ii gcc-4.8-base:amd64 4.8.1-2 amd64 GCC, the GNU Compiler Collection (base package)
ii libgcc-4.7-dev:amd64 4.7.3-4 amd64 GCC support library (development files)
ii libgcc1:amd64
|
It is Debian's fault for sure, because from within Gentoo-livecd everything is working as it should.

from the chroot, what does | Code: | | grep -i ccache /etc/portage/make.conf |
show?

No ccache here just plain stage3.
As I said everything works fine when I'm using gentoo-minimal-install.iso, so make.conf is ok I guess. Anyway here it is:
| Code: | CFLAGS="-march=k8 -msse3 -O2 -pipe"
CXXFLAGS="${CFLAGS}"
# WARNING: Changing your CHOST is not something that should be done lightly.
# Please consult http://www.gentoo.org/doc/en/change-chost.xml before changing.
CHOST="x86_64-pc-linux-gnu"
# These are the USE flags that were used in addition to what is provided by the
# profile used for building.
USE="bindist mmx sse sse2"
MAKEOPTS="-j3" |

I did that several times both on my custom 3.10 and distro 3.2
Chroot steps for both Debian and Gentoo-minimal-install.iso:
| Code: | mount -t proc none /mnt/gentoo/proc
mount --rbind /sys /mnt/gentoo/sys
mount --rbind /dev /mnt/gentoo/dev
chroot /mnt/gentoo /bin/bash |

Alright, let's make sure all facts are correct. You can boot from Gentoo CD and everything is fine in chroot? If this is true, why don't you go forward and install Gentoo next to your Debian installation? Or I'm missing something here?

Yes it's true, and I already did that, but now I'm trying to setup Gentoo inside encrypted LVM, and I have some issues with generating proper initrd.
It seem that I'll need to use Dracut which is completly new for me. So I really need access to firefox to setup dracut properly. It would be prefect if I could do that from Debian where I've got all the links and stuff about dracut. I don't want to use live cd even with gui, because I'll have to retype my insanely long password to wifi every time.
So it's a matter of convenience for me. |

|

Why are you way back on march=k8? Is this an old athlon core that doesn't support svm? If worst comes to worst, you could always install one and then use xen or kvm or something with libvirt to virtualize the other.
Can you even get the gcc in the chroot to -dumpspecs or --version? |

Isn't march=k8 a proper flag for this CPU?

you might need to recompile the gentoo gcc using debian's gcc before starting. There are a LOT of kernel settings that influence how your compiler was built. Debian's kernel is probably set up differently than the gentoo minimal install kernel. Trying to run a compiler binary compiled for gentoo's min install kernel is almost guaranteed to fail at some point.
I think that's what Tractor Girl might have been getting at.
What happens is when you run ./configure, it examines alllll your kernel settings when configuring the source. Very important stuff. Then, gcc compiles it based on how the source is configured which is configured based on how the kernel is set up. So gentoo's gcc in the stage3 might be configured bass ackwards to work with the debian kernel. Remember gcc is compiled from source too, so it has to be configured for the kernel you are using to run the compiler binary.
generally you want to use the gcc that was built for the kernel that is running, to compile anything. That's why you need to recompile gcc pretty soon after you compile your kernel.
I'm actually surprised you got this far using a debian kernel with stage3. This is called "binary compatibility" and isn't guaranteed between distributions.
from: http://luv.asn.au/overheads/compile.html
"There is no easy way to find out the options used to configure your current kernel."
I can attest to this. even if you have the source package for the current kernel running in your distro, there's no guarantee that the makefile and .config is remotely similar to the running kernel.
If you don't believe me, fire up a red hat distro and recompile the kernel using the src rpm from the cdrom you installed from, without changing it, then reboot. Let me know how that works out for you 
This operation used to result in kernel panics, broken binaries, and mass hardware failures lol. |

run gcc -dumpspecs > dumpspec.gentoo in chroot, then run it out of chroot (gcc -dumpspecs > dumpspec.debian), and diff the results. |

Well It isn't installed on Gentoo but I forgot that I actually installed it on Debian !
It was Debian's ccache fault all the time  |
