ldd not finding shared object (.so) for xerces

I am trying to run a sample executable provided with Xalan C++ library, which requires a the Xerces C library. But I am not able to properly link the Xerces shared object file.

mike@ubuntu:~/Xalan-C_1_9_0-redhat_80-gcc_32/bin$ ldd SimpleXPathAPI 
    linux-gate.so.1 =>  (0xf7765000)
    libxalan-c.so.19 => /home/mike/Xalan-C_1_9_0-redhat_80-gcc_32/lib/libxalan-c.so.19 (0xf7409000)
    libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xf73ab000)
    libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xf738e000)
    libxerces-c.so.26 => not found
    libxalanMsg.so.19 => /home/mike/Xalan-C_1_9_0-redhat_80-gcc_32/lib/libxalanMsg.so.19 (0xf7386000)
    libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf71d8000)
    /lib/ld-linux.so.2 (0xf7768000)
    libstdc++.so.5 => not found
    libxerces-c.so.26 => not found

I included the location containing the libxerces-c.so in my LD_LIBRARY_PATH but ldd will not find it.

mike@ubuntu:~/Xalan-C_1_9_0-redhat_80-gcc_32/bin$ echo $LD_LIBRARY_PATH
    /home/mike/Xalan-C_1_9_0-redhat_80-gcc_32/lib:/usr/local/lib

I even added a soft link to ensure the .26 is included.

The first time I had this => not found issue with libxalan-c.so.19 I solved it by adding the location of that file to my LD_LIBRARY_PATH. So I can't figure out why the same fix is not working for the libxerces-c.so.26. Does anyone know what I'm doing wrong?

Solution

What does this produce:

cd /usr/local/lib
file -L ./libxerces-c.so.26

Chances are, this will print something like ELF 64-bit LSB shared object ..., in which case you are trying to point 32-bit executable at 64-bit libraries, and that doesn't work.

You need to download a 32-bit build of libxerces.
