[gdal-dev] gdaltransform utility not working in web service

[Dinesh Dass Subramanian]

Dear Frank,

Thanks for your help. I have added the LD_LIBRARY_PATH and there is no
error in the output file.But new message is coming while I try to
execute the gdaltransform or any other utility in my web service.

op.text
--------
 Usage: gdaltransform [--help-general]
      [-i] [-s_srs srs_def] [-t_srs srs_def] [-to \"NAME=VALUE\"]
      [-order n] [-tps] [-rpc] [-geoloc]
      [-gcp pixel line easting northing [elevation]]
      [srcfile [dstfile]]

I have debugged the code and upto the commandline class, it is working
fine. The commandline class is able to interpret the gdaltransform as
executable and the remaining strings as arguments. But the exectask
class could not execute the command. Please suggest. Thanks.
