Is MapServer using the same GDAL as the commandline GDAL that can successfully open the file?

Hello All, I have been trying to read a custom GDAL raster format via MapServer. (Unfortunately, I'm unable to share the file itself here, as it is a proprietary format). MapServer is unable to read the raster and display it. However, GDAL is able to read (gdalinfo, etc), translate (gdal_translate), transform (gdalwarp) the raster. Any ideas how to solve this? MapServer is compiled with GDAL support and everything looks OK. The "gdalinfo --formats " command shows the format is supported. Here are the errors in my log: msDrawMap(): rendering using outputformat named png (AGG/PNG). msDrawMap(): WMS/WFS set-up and query, 0.000s msDrawRasterLayerLow(testLayer): entering. msDrawRasterLayerLow(): Unable to access file. Corrupt, empty or missing file '/path/to/myfile.ext' for layer 'testLayer'. Image handling error. Failed to draw layer named 'testLayer'. msFreeMap(): freeing map at 0xf8b8f0. And here's the MapServer error included in the image or shown on the command prompt (when ran using mapserv command): msDrawMap(): Image handling error. Failed to draw layer named 'testLayer'. msDrawRasterLayerLow(): Unable to access file. Corrupt, empty or missing file '/path/to/myfile.ext' for layer 'testLayer'. GDAL: GDALDeregister_GTiff() called. Here's how my layer definition looks like: LAYER NAME "testLayer" TYPE RASTER DATA "/path/to/myfile.ext" # <<-- Tested with realtive path from shapepath and also direct path, as in this case. STATUS ON END Thank you for your helpful pointers. Regards, Shri.
