[gdal-dev] JPEG2000 question/issue
I'm wondering if someone can help me with this. I'm trying to build GDAL with both support for MrSID and ECW while using the former for JPEG2000 support. It appears that as soon as libecw is linked in, it is being used as the JPEG2000 reader (even when I have MRSID_FLAGS = -DMRSID_J2K uncommented in the make options). I'm assuming this probably has something to do with the order that the drivers are tried at runtime. Is there a correct way to force the support to default to the MrSID library? Thanks for the help.

Christiaan, Disabling the -DMRSID_J2K should disable the JP2MRSID driver though you may need to do a clean build for the change in the nmake.opt to take effect. Alternatively you can force a particular driver to be ignored at runtime using the GDAL_SKIP configuration variable. Set it to the driver name you want to ignore ... such as JP2MRSID. It can be set in the environment, before running GDAL commands. set GDAL_SKIP=JP2MRSID Best regards, -- ---+-- I set the clouds in motion - turn up | Frank Warmerdam, [EMAIL PROTECTED] light and sound - activate the windows | http://pobox.com/~warmerdam and watch the world go round - Rush| Geospatial Programmer for Rent ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
RE: [gdal-dev] JPEG2000 question/issue
Actually, I want the MrSID library to handle JPG2000 instead of the ECW library, while still maintaining support for standard ECW files. I think what your describing would be the opposite.

RE: [gdal-dev] JPEG2000 question/issue
Interesting. I'd like to disable NITF handling, is this also possible in the same way using GDAL_SKIP? Where is the definitive list of format names that can be used in this way? thanks, Mike -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Frank Warmerdam Sent: Monday, October 27, 2008 11:24 AM To: Christiaan Janssen Cc: gdal-dev@lists.osgeo.org Subject: Re: [gdal-dev] JPEG2000 question/issue Christiaan Janssen wrote: I'm wondering if someone can help me with this.
