Hi, I think I've found a small bug in the current libpng port. The 32bit-version binds to libmath (-lm) and zlib (-lz): danm@torax:~$ ldd /chroot32/usr/lib/libpng.so linux-gate.so.1 => (0xffffe000) --> libm.so.6 => /lib32/libm.so.6 (0x5559e000) --> libz.so.1 => /usr/lib32/libz.so.1 (0x555c1000) libc.so.6 => /lib32/libc.so.6 (0x555d2000) /lib/ld-linux.so.2 (0x56555000) The 64bit-version has no references to those libraries. danm@torax:~$ ldd /usr/lib/libpng.so libc.so.6 => /lib/libc.so.6 (0x00002aaaaabec000) /lib64/ld-linux-x86-64.so.2 (0x0000555555554000) I've attached an updated port. Maybe some of you will find it useful. I came across this problem while trying to compile SLiM. bye, danm -- Daniel Mueller http://www.danm.de Berlin, Germany OpenPGP: 1024D/E4F4383A
