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

[John Cartwright]

Hello All,

I'm trying to compile 1.4.2 on a RHEL 5 platform.  I configured using 
"--with-gif=internal", but during the compilation process I'm stopped by:
...
gcc -c -I/extra/contrib/src/gdal-1.4.2/port

-I/extra/contrib/src/gdal-1.4.2/alg -I/extra/contrib/src/gdal-1.4.2/ogr

Can anyone suggest what I might be doing wrong here?

Thanks!
