Yes that's the error message. It goes on the say somthing about
trying to find gcs.csv which is there but since it can't find the
env var, it doesn't find the data. This is weird because I set the
env var using the win32 function SetEnvironmentVariable() before
the call to OGRSpatialReference is made. Since I was setting the
variable and getting this message I suspected that GDAL_DATA was
being read by something at startup.
Hi,
I'm afraid you won't be able to set the environment variable this way.
GDAL is using getenv() to retrieve the value which operated on a local
copy of the variables created when the process is started. By this
means the env variable should be set before the process is spawned.
Is there some code I can write that can tell me what gdal thinks
the GDAL_DATA env var is set to?
You should instead use SetConfigOption or PushFinderLocation (both
exposed to the SWIG API) for this purpose.
Best regards,
Tamas
