<br>
You need to make sure that the reference to the proj library that's in<br>
libgdal can be found at link time for the test_ogrsf executable. You<br>
can do this by setting LD_LIBRARY_PATH environment variable to the<br>
directory containing the relevant proj library. You could also edit<br>
the link line to include a reference to that directory (see the<br>
-rpath-link option). I would think that an RPATH entry would be<br>
created in the GDAL library when it's built, which would take care of<br>
this, but I'm not sure why this wouldn't be happening without a bunch<br>
of investigation.<br>
<br>
This might be helpful:<br>
