[Gdal-dev] compile problems re: GIF on RHEL 5/64-bit platform

[John Cartwright]

Hi Doug,

thanks for the suggestion. I was able to get gdal to compile using a 
modified egif_lib.c that Frank supplied. However, strangely the gdal 
executables don't seem to be able to find some of the shared libraries 
even though the directory is listed in the LD_LIBRARY_PATH variable. Did 
you have any issues like this? It may be a problem specific to RHEL 5.

Thanks again!
