<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">After carefully following the advice here on the lists and the Raster driver tutorial GDAL isn’t loading the driver.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am relying on the AutoLoadDrivers function.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When I GDALAllRegister(), followed by a GDALOpen(“path/to/custom/raster.ext”, RA_ReadOnly);, GDAL states that the file is not recognized as a supported file format. The application was built against the exact version of GDAL used to link
the custom driver code. GDAL 3.7.2<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I tried running an older GDAL version (3.6.3) in a python environment. When I `from osgeo import gdal`, there are two errors that are printed.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<ol style="margin-top:0in" start="1" type="1">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">Can’t load requested DLL – then it printed the full path and file name of the driver .dll, so it can find it!<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">The specified procedure could not be found<o:p></o:p></li></ol>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">These look like python specific error messages to me, and probably stem from a gdal version mismatch. I’m assuming #2 is emitted in a trivial sense because the .dll could not be opened. Curiously the error message was printed twice. I
did not expect this to work but my hope was to see a more detailed error message.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have exported the GDALRegister_X() function, in accordance with the documentation. The driver code compiles cleanly and follows almost verbatim with the tutorial.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">How should I approach diagnosing the problem?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Best,<o:p></o:p></p>
<p class="MsoNormal">Jesse<o:p></o:p></p>
