 Posted: Thu Jul 15, 2021 8:38 pm Post subject: [SOLVED] Recovering from x86_64-pc-linux-gnu removal |
 |
|
So... I was trying to remove my mingw cross-compilers that are used for wine, but not knowing that crossdev wasn't its own thing, I accidentally ended up removing gcc:
| Code: | # crossdev -C i686
* Uninstalling target 'i686-pc-linux-gnu' ...
# crossdev -C x86_64
* Uninstalling target 'x86_64-pc-linux-gnu' ... |
Thankfully I keep binpkgs of everything I install. I used the instructions from https://forums.gentoo.org/viewtopic-t-1009338-start-0.html to get x86_64-pc-linux-gnu back:
| Code: | # cd /data/star/portage/cache/binpkgs/sys-devel
# tar -xjpf gcc-10.3.0.tbz2 -C / |
And now I can actually run programs again! But I still don't have i686 and I feel like that might be important...
The thread also suggests "it's recommended to build gcc again just to make sure the package metadata on your system is correct" but I can't because "C compiler cannot create executables". I get a different message for different packages. Here are the results for gcc.

haruka,
Exactly what command did you use to install gcc from the tarball?
An you have a multilib install, your x86_64-pc-linux-gnu gcc can build both 64 bit and 32 bit code. Thats the -m64 and -m32 options.
You cannot install the 32 bit i686-pc-linux-gnu tools on that system as it would install some of the same files as your multilib gcc, and none of the 64 bit files.
| Code: | configure:4488: gcc conftest.c >&5
gcc: fatal error: cannot execute 'as': execvp: No such file or directory
compilation terminated. |
as is the ASsembler.
Selecting your active gcc with gcc-config rewrites the symlinks. That's worth trying.

I used | Code: | | emerge -1 --usepkg =gcc-10.3.0 |
and got:
| Code: | >>> Running pre-merge checks for sys-devel/gcc-10.3.0
libgcc_s.so.1 must be installed for pthread_cancel to work
Aborted |
And so I used, | Code: | | tar -xjpf gcc-10.3.0.tbz2 -C / |
from my binpkg directory. I presume I missed some post-install configuration that emerge would normally take care of and that's where my current issues stem from?

I think I understand. Maybe I never even had an i686-pc-linux-gnu folder.

I already selected it earlier, but I tried it again anyways.
| Code: | # gcc-config -f 1
* Switching native-compiler to x86_64-pc-linux-gnu-10.3.0 ...
>>> Regenerating /etc/ld.so.cache... |
But, I think I'm seeing what you want now. I looked back an old install (from a month ago, also gcc 10.3.0) and I see:
| Code: | # diff -q /old/usr/x86_64-pc-linux-gnu/ /usr/x86_64-pc-linux-gnu/
Only in /old/usr/x86_64-pc-linux-gnu/: bin
Common subdirectories: /old/usr/x86_64-pc-linux-gnu/binutils-bin and /usr/x86_64-pc-linux-gnu/binutils-bin
Common subdirectories: /old/usr/x86_64-pc-linux-gnu/gcc-bin and /usr/x86_64-pc-linux-gnu/gcc-bin
Only in /old/usr/x86_64-pc-linux-gnu/: i686-w64-mingw32
Common subdirectories: /old/usr/x86_64-pc-linux-gnu/lib and /usr/x86_64-pc-linux-gnu/lib
Only in /old/usr/x86_64-pc-linux-gnu/: x86_64-w64-mingw32 |
Are these the symlinks in question? This bin folder doesn't exist in my current messed-up state and wasn't created/repopulated by gcc-config.

Any advisable path? Any harm in copying in the missing links since they're from the same hardware and gcc version? |

I spoke too soon.
I should have used -r with diff and I would see that binutils was actually missing its binaries - therefore, I emerged binutils using --binpkg, and then I could re-emerge gcc using --binpkg, and it created all the links in question.
I then finished a from-source gcc reinstall. And then I had to do pkgconf, and afterwards an emerge @world went off successfully.
I guess everything is fine again so I'll mark as solved, but please speak up if you can think of anything I might have missed that will cause me trouble down the line. |
