[Mapserver-users] php mapscript config help!

[Vincent Schut]

Mark,

you can check which gdal is being linked at runtime by typing 'ldd 
php_mapscript.so' (in the dir where php_mapscript.so is). It will give you 
info on all dynamically linked libraries.
Note that you have to run 'ldconfig' (as root) everytime you (re)install a 
library, like gdal. And that the dir where the library gets installed must be 
in the /etc/ld.so.conf file, or in the LD_LIBRARY_PATH environment variable. 
And that the order in which dirs are in this file or var basically defines 
which one of two versions of a library file will be loaded if you have for 
example an old version still in /usr/lib and a newer in /usr/local/lib. If 
/usr/lib is first in the path row, it will be used, and vice versa. Self 
compiled libraries usually install in /usr/local/[lib|include|etc]; Distro 
packages like rpms usually get installed into /usr/[lib|include|...]. If you 
want to use your self compiled one, you'd better remove the preinstalled one 
if there was one. And then rerun ldconfig, to refresh the dynamic linker 
database/cache.

Good luck,
Vincent.
