I am working with an in-house utility written a couple of years ago that
uses the MEM driver. Recently, after upgrading to Vista64 the utility
stopped working. As it was using an old version of GDAL, I decided to fetch
the source from the vault and recompile/link against GDAL 1.5.2. I didn't
change any code, but the new utility is failing with "ERROR 1: Missing
required field (one of PIXELS, LINES, or DATAPOINTER)"
I'm assuming the problem is either incorrect source (old code), a 64 bit
issue, or a GDAL version issue. Before I start modifying the code to
allocate memory and include a DATAPOINTER I thought I'd ask if there were
any changes between GDAL 1.4 (Maybe older) GDAL 1.5.2 that might cause this
or if it is a well known Vista 64 problem?
Here's the snippet of code that is fails on the poMemDriver->Create(.) line:
GDALDriver* poMemDriver;
CString format = "MEM";
CString filename = "MEM:::";
poMemDriver = GetGDALDriverManager()->GetDriverByName(format);
if (poMemDriver == NULL)
{
cout << "\"MEM\" driver not supported." << endl;
return false;
}
m_poUtmRgbDataset = poMemDriver->Create( filename,
m_poSrcDataset->GetRasterXSize(),
m_poSrcDataset->GetRasterYSize(),
3, // 3 Bands, Red, Green, and Blue
GDT_Byte,
NULL);
