[Description Mark Keisler 2010-07-20 15:05:32 UTC]

When trying to emerge xfce-base/libxfcegui4-4.6.4, it fails with this error:

/usr/lib/gcc/i686-pc-linux-gnu/4.3.4/../../../../i686-pc-linux-gnu/bin/ld: cannot find -lpng12
collect2: ld returned 1 exit status

[Comment 1 Eckard Brauer 2010-07-20 15:26:06 UTC]

Same here.

Because libpng-1.4.3 already has /usr/lib/libpng12.so.0, I fixed it setting the missing link:

ln -s libpng12.so.0 /usr/lib/libpng12.so

After that, emerging runs fine (BTW, also avahi-0.6.25-r1 has that problem).

[Comment 4 Mark Keisler 2010-07-20 15:37:59 UTC]

marking this bug as a duplicate of an "INVALID" bug with no remediation seems invalid in itself.

Also, ln -s libpng12.so.0 /usr/lib/libpng12.so makes no sense.

Something needs to be fixed in some way.

[Comment 5 Mark Keisler 2010-07-20 16:07:51 UTC]

Aha, digging through the others related to the duplicate I found the solution:

/usr/sbin/libpng-1.4.x-update.sh
