[SOLVED] Downgrading package & update log

Hi!

After recent update of packages some programs failed to launch. Example of one of them:

11:26:17 AM: Debug: pthread_mutex_[timed]lock(): mutex not initialized
*** Error in `XXX: free(): invalid pointer: 0x0000000000b7d758 ***
======= Backtrace: =========
/usr/lib/libc.so.6(+0x72055)[0x7f3902e75055]
/usr/lib/libc.so.6(+0x779a6)[0x7f3902e7a9a6]

XXX[0x41a70a]
/usr/lib/libc.so.6(__libc_start_main+0xf0)[0x7f3902e23610]
XXX[0x41be69]
======= Memory map: ========
...Lots of memory map, nothing suprising for linux programmers...

I barely remember that wxWidgets was updated but I am not sure.

1) How can I view update log?
2) How can I downgrade package from AUR?

Thanks in advance.

P.S. I tried to compile a new version of program from AUR, but it didn't work, so it seems there is
programming error either in wxWidgets or in the program which uses xwWidget in a way which corrupts mem.
In any case, the question is about rolling back a package, please do not send me to relevant bugzilla.

Re: [SOLVED] Downgrading package & update log

Please use code tags.

Have you done your research on the wiki?
Especially: https://wiki.archlinux.org/index.php/Do … g_packages

As for update logs, I think it is something like

journalctl -u pacman

See here for journalctl usage.

Furthermore: Did you do a full upgrade? (pacman -Syu)
Have you read anything about the switch to GCC 5?
https://bbs.archlinux.org/viewtopic.php?id=194029

EDIT: I feel this is the wrong place for this thread, so I am reporting to draw mods attention.

Re: [SOLVED] Downgrading package & update log

1 - log is @ /var/log/pacman.log
2 - have a look at https://aur.archlinux.org/packages/downgrade/

Obviously the better option is to specify which application actually crashes so we can help you with updating those; instead of downgrading everything else

Deleting & reinstalling packaged helped.

P. S.  journalctl -u pacman doesn't work.

Good to hear you solved it.
And I realized afterwards, as Spider.007 said, the pacman log is just a file.

Some friendly advice:
you should subscribe to the newsletter, I got an e-mail a few days ago telling me about this huge switch to GCC5.
It also gave a small script to check which packages would need to be rebuild.
