<div style="word-wrap:break-word"><div> 3. Some other tweaks and changes as described in [1] to get also Swig Java bindings working</div><div><br></div><div>b) Runtime problems. Main problem is that some OGR drivers do not open some of test files, even if ogr.GetDriver() reports them. See [2] for reported the list.

</div></blockquote><div><br></div></div><div>You could customize error handling to log to a file or some other suitable mechanism from gdal/port/cpl_error.cpp, and also turn on debug output. For a logging error handler do this near the start of your program:<br>
</div><div><br></div><div> CPLSetConfigOption("CPL_LOG", "/tmp/your.log");</div><div> CPLPushErrorHandler(CPLLoggingErrorHandler);</div><div><br></div><div>to enable debugging output do:</div>

<div><br></div></div></div></div></blockquote><div><br></div></div><div>I tried that now with mixed results. The file logger works with GDAL, but not with OGR. So for this specific issue could not use it. But I managed to hack at least error messages (stdout) to Android own logger, and got the info what I needed:</div>

<div>This last one brings me to two questions: </div><div><br></div><div>a) where can I define folder from where the EPSG support files are read from? When I had similar problem with proj.4, then I did ugly hack (almost hardcoded) to pj_open_lib.c, and there is PROJ_LIB variable, but I could not find similar thing for GDAL. Android JNI does not provide easily packaged files for C++, but that's another story.</div>

If I compile gdal without proj.4 then does OSR provide some kind of lite standalone replacement for it?</div>
