 Posted: Fri Sep 23, 2022 7:32 pm Post subject: [SOLVED] rpi3 broken emerge - libffi |
 |
|
Hi, update of world at fairly old gentoo system on my rpi3 got interrupted by power outage (not sure if it is the cause) and now emerge complains about missing /usr/lib/libffi.so.7. There is already installed /usr/lib/libffi.so.8 on that system. I was looking at current stage3, but it also contains libffi.so.8. What will be the easiest way to fix this? Is it likely that I will be able to build libffi.so.7 on that system? Which libffi version installed so.7? Or is there a way to use stage3 to somehow fix portage on that system? Thanks.

krotuss,
dev-libs/libffi is not slotteh so you may not have several versions installed at the same time.
Does your Pi3 have a 32 bit or 64 bit install?
Please post the full command and output including the error message.

Moved from Portage & Programming to Gentoo on ARM.
The Pi3 is arm or arm64

Which command do you mean specifically? I currently don't have access to that system, but every emerge command that I have tried fails with python backtrace with complain about missing "/usr/lib/libffi.so.7" at the bottom. It looks like that libffi was updated, but emerge/python/dependencies was not rebuild against newer "/usr/lib/libffi.so.8"
System is 32 bit.
Looks like 811462 |

Posting output of emerge command:

ImportError: libffi.so.7: cannot open shared object file: No such file or directory |
I was able to build libffi-3.3-r2 outside of portage on my affected system and manually placed .so.7 files into /usr/lib. That fixed emerge. |
