Package: libpng12-dev Version: 1.2.54-2 Severity: grave The fix for bug #766809 broke linking with -lpng12 on at least amd64. I noticed the problem when libkate failed to build in <URL: https://buildd.debian.org/status/fetch.php?pkg=libkate&arch=amd64&ver=0.4.1-6&stamp=1455665747 >.
The cause is a dangling symlink after the symlink from /usr/lib/${DEB_HOST_MULTIARCH}/libpng12.so.0 was removed: % ls -lh /usr/lib/x86_64-linux-gnu/libpng* lrwxrwxrwx 1 root root 10 Feb 16 13:33 /usr/lib/x86_64-linux-gnu/libpng.a -> libpng12.a lrwxrwxrwx 1 root root 11 Feb 16 13:33 /usr/lib/x86_64-linux-gnu/libpng.so -> libpng12.so -rw-r--r-- 1 root root 238K Feb 16 13:33 /usr/lib/x86_64-linux-gnu/libpng12.a lrwxrwxrwx 1 root root 13 Feb 16 13:33 /usr/lib/x86_64-linux-gnu/libpng12.so -> libpng12.so.0 % Setting the severity to grave as this break the library completely. -- Happy hacking Petter Reinholdtsen
