[Gdal-dev] Some newbie can't open MrSID

[William Lyons]

Hello,

After successfully building the source (kudos for the relatively
painless build even in windows), I've been learning all I can about how
to use GDAL from the online tutorials.  But, I have hit a snag.  I can't
open MrSID files.  I tried the following:

    GDALDatasetH  hDataset;
    GDALAllRegister();
    hDataset = GDALOpen( argv[1], GA_ReadOnly );
    if( hDataset == NULL )
    {
		printf("File not opened\n");
		return 1;
    }

	const char *sidFormat = "MrSID";
    GDALDriverH sidDriver = GDALGetDriverByName( sidFormat );
    char **sidMetadata;

    if( sidDriver == NULL )
	{
		printf( "No MrSID Support!!" );
        exit( 1 );
	}

Most of it is straight out of the tutorial and I always get "No MrSID
Support!!"

Thanks,
William Lyons
