I am trying to use the GDAL merge tool and receive the following error message:

The process failed to start. Either the invoked program is missing, or you may have insufficient permissions to invoke the program.

On install I checked the "Path to the GDAL Executables" and it already had the /usr/bin added to the install. Here is what I have in this field:


Thanks in advance for any help with this issue

By the path you have shown, I'm going to assume you are using a Mac. Also assuming you have used the standard installer for GDAL.

Try this path instead:


The 'Versions/1.9/Programs/usr/bin' subdirectory doesn't exist, but the Versions/1.9/unix/bin does and should only contain the gdal-config tool (not used by GDALTools plugin). The binaries used by the GDALTools plugin should all be located in the Programs directory listed above.

Test by running the Raster->Miscellaneous->Information tool on a raster layer.

Thanks for the help, I receive tis strange error when running the info tool. Not sure if this is an error on my end. I am using a raster dataset I am unfamiliar with. "ERROR 4: `/Users/jdlancaster/Desktop/canyon_city-w' does not exist in the file system, and is not recognised as a supported dataset name. gdalinfo failed - unable to open '/Users/jdlancaster/Desktop/canyon_city-w'. – J_L Nov 2 '12 at 23:01
Nevermind last post. I placed the raster files under a new directory and forgot to change this in the GIS. It seems to work now, thanks for your help. – J_L Nov 2 '12 at 23:07
