[ptx] Problems to link /usr/lib32/libpng.so.2 for Panotools 32bit (crosspost: gmane.linux.debian.ports.amd64)

[Gerhard Gaussling]

Hello,

I got a problem to run 32bit panotools on my amd64 breezy box.
I linked successfully 32bit libpano12 and libtiff.so.3, but I'm not able 
to
link libpng.so.2.

$ ldd PTStitcher         linux-gate.so.1 =>  (0xffffe000)
        libpano12.so => /lib32/libpano12.so (0x5558f000)
        libc.so.6 => /lib32/tls/libc.so.6 (0x555c6000)
        libm.so.6 => /lib32/tls/libm.so.6 (0x556f4000)
        libjpeg.so.62 => /usr/lib32/libjpeg.so.62 (0x55716000)
        libtiff.so.3 => /usr/lib32/libtiff.so.3 (0x55735000)
        /lib/ld-linux.so.2 (0x55555000)
        libpng.so.2 => not found
        libz.so.1 => /usr/lib32/libz.so.1 (0x55783000)

$ sudo /sbin/ldconfig -v -l /usr/lib32/libpng.so.2
/sbin/ldconfig: Ignored file /usr/lib32/libpng.so.2 since it is not a
regular file.

$ cat /etc/ld.so.conf|grep 32

I also set up a chroot environment which linked the png library the 
right
way. I copied the png libs from that environment to /usr/lib32.

        libz.so.1 => /usr/lib/libz.so.1 (0x55783000)

But anyway: I want to know why it fails to link /usr/lib32/libpng.so.2, 
but
linking /usr/lib32/libtiff.so.3 works, and also linking in chroot32 
works.

Is there a way to have /usr/lib32/libpng.so.2 working without chroot?

kind regards
