[gdal-dev] Multithreading issue on pixel-based intensive access (GDAL 2.1.0)

[Francisco Javier Calzado]

Thank you Even,

I maganed to compile properly in x86 today. I was setting WIN64 to NO, instead of just commenting it out. Maybe that was the culprit. 

Unfortunately, I still get the same error:

ERROR 7: Assertion `poNewest->poPrevious == NULL' failed
in file `c:\ericsson\3rdparties\gdal-2.1.0\gcore\gdalrasterblock.cpp', line 800

I have attached a simple code to reproduce it (Test.cpp). If you need the whole solution just ask me, although it is a very simple console test. I have also shared with you the zipped datasets through this link:
https://drive.google.com/file/d/0B-OCl1FjBi0YblRPRGZlQWx4eEE/view?usp=sharing
Just place them along with Test.exe file.

IMPORTANT: Bear in mind that these datasets come in a format still not supported officially by GDAL, as I am developing the driver. It is almost finished (just a few details pending) and fully working. Find the driver attached (Wizard_Driver.7z). 
By the way, what do we have to do to contribute with this new driver for GDAL?

Thank you so much Even.

Javier.

Javier,

Make sure the Visual Studio 32bit environment is properly set up. Check that
WIN64 from nmake.opt is let commented out.
Example of successful build:
