Gentoo updates refuse to install both versions 6 and 7 of jpeg,
and I have found that certain applications, like emacs, refuse
to remerge with -7 so I have been refusing the -7 update for a
month or two now. Every once in a while, one slips by me,
usually because I forget to remove thunderbird from the list of
updates, and I find out when emacs won't run. If I try to build
emacs with -7, it complains, so I remerge jpeg-6 and then emacs
is happy again. I do not understand the compat lib; it also blocks,
and since I can just refuse the -7 update and keep on working, I
have not looked into it much, figuring that sooner or later emacs
and other packages will be upgraded to handle jpeg-7.
Recently another jpeg-7 upgrade slipped past me, only this time it
got weird. I remerged jpeg-6 and found that emacs now complained
that jpeg-7 was missing. Here is "ldd /usr/emacs/bin|grep jpeg":
libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0x00007f0cbd19f000)
libjpeg.so.7 => not found
Now I am puzzled. If jpeg-6 and -7 block each other, how did
emacs end up expecting both? If I try to emerge emacs with -6
installed and -7 missing, it complains that gtk is not installed properly.
Obviously I am doing something wrong. Gentoo documentation on the
jpeg compatibility lib is so minimal as to be useless, unless I
have just not found the right documentation. If that is the right
solution to my mess, I'd like to get it working, but I can't figure
out how to emerge the compatibility library when it blocks.
These are the packages that would be merged, in order:
