Sujet: [gdal-dev] The proj.dll mistery<br>

Hi,<br>
<br>
OK, I recovered from a mysterious sudden stop working of my gdalwarp<br>
and ogrproj MEX files. All I had were error messages like<br>
<br>
"Failed to create coordinate transformation between the<br>
following coordinate systems. This may be because they<br>
are not transformable, or because projection services<br>
(PROJ.4 DLL/.so) could not be loaded."<br>
<br>
But not long ago those worked ok. It turn out that probably the culprit<br>
was the "VantagePoint" here pointed out recently, that installed an<br>
older (incompatible??) version of proj.dll on "C:\WINDOWS\system32" (I<br>
hate softs that do it).<br>
<br>
When I have dll conflicts, I always use the Dependency Walker to help me<br>
out, but in this case (an others??) the gdal.dll (trunk version) didn't<br>
show up any dependency on proj.dll. So it was a matter of "and what if<br>
it is in system32?" lucky guess that allowed me to solve the problem.<br>
There are plenty of dll dependencies on gdal.dll. Why not on proj.dll?<br>
</blockquote><div><br>Joaquim,<br><br>I had the same problem some time ago, the message you had appeared in the middle of a Matlab session.<br><br>The problem solved when I restarted Matlab ...<br><br>Now that you pointed out that accessing to different releases of proj.dll might cause the problem, I will check it if the message appear again ...<br>
