[gdal-dev] problem w/ libexpat while compiling 1.5.0 on 64-bit RHEL 5

[John Cartwright]

Hello All,

I'm having a little trouble compiling 1.5.0 on my 64-bit Red Hat 
Enterprise Linux 5.1.  The issue seems to be that, regardless of my 
attempts to influence it, configure insists on getting the libexpat.so 
from $ORACLE_HOME and complains that the "File in wrong format".

I've tried using the RedHat-provided expat library (both 32 and 64 bit 
versions), and built a new local copy of expat.  My configure includes 
the lines:

--with-expat-inc=/extra/contrib/expat-2.0.1/include \
 --with-expat-lib=/extra/contrib/expat-2.0.1/lib \

but I still see lines like the following during the make, suggesting 
that the correct expat library is not being found:

The LD_LIBRARY_PATH variable has been unset. Can someone give me advice 
on how to work around this situation?

Thanks!
