Linux: 'Could not load library pano12'
This email was just rewritten: initially I was planning to ask for help 
running PanoTools for Linux because whatever I tried I always got 
        Could not load library pano12
when I ran 
        java -jar ptpicker.jar

Only a few seconds ago (but many hours of searching Google and downloading 
various versions of libpano12.so and ptpicker.jar later) I found that all I 
needed to do was run (as root)
        /sbin/ldconfig
after copying libpano12.so to /usr/local/lib. Fairly obvious and although I 
briefly wondered if simply copying the file was enough the instructions I 
found all suggested that this was the only step involved so I did not search 
in this direction. Perhaps you can include this in the Linux installation FAQ?

Hi there,
We still get the same error even after installing libpano12.so into /lib, /usr/lib and /usr/local/lib and running /sbin/ldconfig.
Any more suggestions!?!
Cheers,
E.
I had the same problem after trying ldconfig and setting LD_LIBRARY_PATH.
After a while I thought that the problem was not with the java file finding the library, rather that the library had some dependencies. So I tried the following
$ ldd /usr/lib/libpano12.so 
        libm.so.6 => /lib/i686/libm.so.6 (0x40045000)
        libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0x40068000)
        libtiff.so.3 => /usr/lib/libtiff.so.3 (0x40089000)
        libpng.so.2 => not found
        libc.so.6 => /lib/i686/libc.so.6 (0x400cd000)
        libz.so.1 => /lib/libz.so.1 (0x401ed000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
In my case I was missing the library libpng.so.2. My distribution (Mandrake 9.0) did not contain this file, but a later version, 3.1.2.4, so I created (as root) a link: ln -s /usr/lib/libpng.so.3.1.2.4 /usr/lib/libpng.so.2
and now it seems to work.
Hope this works

I tried the above, but there were no missing dependencies.Only did ldd not ask for a libpng. All the others were found, but still the same 'could not load library pano12' I used the libpano from the update LINUX more suggestions? Rik
I also got the error "Could not load library pano12". I've already copied the libpano12.so to /usr/local/lib and executed /sbin/ldconfig (no need to say that /usr/local/lib is in ld.so.conf). Next I checked the dependences of libpano12.so with "ldd". So I found that I need to make a link of libm.so.5 that points to /lib/libm.so.6. After running ldconfig I still got the same error. Finally I checked with strace what goes wrong: strace java -jar ptpicker.jar 2> debug.txt The Library wasn't ever search in the ld.so.conf specified path but in the library path of the Java runtime enviroment ($JAVA_HOME/lib/i386). So I put a link into $JAVA_HOME/lib/i386/libpano12.so that point to my old /usr/local/lib/libpano12.so that is used by the native parts of PanoTools.
