Hello,
I am trying to use IDL's spawn to call OGR/GDAL binaries but am experiencing some conflicts in the libraries IDL points to. It will call the executable I want, but it finds OGR/GDAL library references that were not part of the current GDAL build. They appear to be the ones that come installed with IDL. An example:
$ ogrinfo -al all_calibration_plots.shp | head -5
INFO: Open of `all_calibration_plots.shp'
using driver `ESRI Shapefile' successful.
Layer name: all_calibration_plots
Geometry: Polygon
Feature Count: 81
$ idl
IDL> spawn,'ogrinfo -al all_calibration_plots.shp | head -5'
ogrinfo: /usr/local/itt/idl/idl80/bin/bin.linux.x86_64/libgdal.so.1: no version information available (required by ogrinfo)
ERROR 1: ogrinfo was compiled against GDAL 1.10 but current library version is 1.6
Any way to get around this? I'm guessing its a path reference we need to change somewhere.

Depending on the flavor of Linux, you may need to appending your shell's LD_LIBRARY_PATH onto the beginning of your SPAWN command, or spawn a script that's responsible for setting LD_LIBRARY_PATH first.
Compare and contrast :
$ echo $LD_LIBRARY_PATH
IDL> print, getenv('LD_LIBRARY_PATH')
