PostPosted: Mon Apr 15, 2002 2:50 am    Post subject: current libpng problem Reply with quote

after doing an emerge --update world
i found all my icons had disappeared off my gnome menus and such, and wouldnt display.

i read in the bugs database that this is a libpng problem.

Does anyone know a workaround for this problem? can i somehow use the old png libs that worked previously by linking to them or something?

This is what i have found for a quickfix workaround. Worked for me anyways.
-------------------

its a good idea to make sure gentoolkit is already installed:
emerge gentoolkit

then make sure the paths are right:
ln -s /usr/bin/qpkg /usr/sbin

then run the scripts to get a list of what you need to recompile:

/usr/portage/media-libs/libpng/files/libpng-update-libs.sh

then:

/usr/portage/media-libs/libpng/files/libpng-update-bins.sh

Write down the packages you see after each script runs.

then just emerge the packages you wrote down to recompile them with libpng.

Many thanks to all those in #gentoo on OpenProjects who helped with this fix.

please note that you will save yourself a lot of compiling if you first emerge the libraries, then run the update-bins script and check, since that will remove all false positives from binaries that link to libraries that link to libpng.

I noticed that the old libpng.so.2 was lingering on my system. Afer a emerge unmerge libpng;emerge libpng it was gone. I believe that the old libpng was one of the problems. I have since ran through the list provided by the scripts and stuff is starting to work again.

Just to note: This did fix everything. I did have to follow the steps above with the libs and bin script. The qt stuff had to be done first. and I had to unmerge qt-2 and qt-3 and then remerge. Then from there up.
