Re: Trouble building GDAL 3.12.3 on Linux

Hi,

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

This might be helpful:
