[gdal-dev] Building for Java on MacOS

[David Rush]

All:

I think I finally found some instructions for building the Java stuff I
need:

https://trac.osgeo.org/gdal/wiki/GdalOgrInJavaBuildInstructionsUnix

That includes some notes for MacOS.  Yay.

I've set up my java.opt per this link referenced in the above link:

https://trac.osgeo.org/gdal/ticket/2401

But when I run "make" from the swig/java directory, I get this error:

GNUmakefile:1: ../../GDALmake.opt: No such file or directory
make: *** No rule to make target `../../GDALmake.opt'.  Stop.

I did a search with "find" but I don't seem to have that file.

What now?
