[gdal-dev] GDAL v1.5.1 compile error on RHEL5.

[Joe Testa]

Hi,

  GDAL v1.5.1 does not compile on my 64-bit RedHat Enterprise Linux 5 
server:

# ./configure
[snip]
# make
...
/usr/bin/ld: skipping incompatible /usr/lib/libsqlite3.so when searching 
for -lsqlite3
/usr/lib/libexpat.so: could not read symbols: File in wrong format
collect2: ld returned 1 exit status
make[1]: *** [libgdal.la] Error 1


   Whats going on is that the linker is building a 64-bit library, but 
was passed the 32-bit version of libexpat in /usr/lib/libexpat.so.  The 
correct behavior would be to link to /usr/lib64/libexpat.so.  I worked 
around this problem by manually editing the GDALmake.opt file and 
changing the /usr/lib reference to /usr/lib64 in the LIBS variable.  
After that, doing 'make' again compiles the package just fine.

   Please let me know if you need any more information to debug this.

   Thanks!
