g.region compilation fails with recent proj

[martinl]

Using fresh proj4 from SVN I am getting error when compiling g.region, see also ​https://trac.osgeo.org/proj/ticket/98

as per comments in ​https://trac.osgeo.org/osgeo4w/ticket/34,

• does it build in 6.5svn and trunk? (see comment 3 in ticket # 34, and r45469 in 6.5svn)

• does it build on wingrass if you use proj-4.7.0-3 from osgeo4w?

Apparently in proj4 trunk svn rev 1975 some headers were dropped from trunk/proj/src/Makefile.in, including the req'd projects.h.

I had hoped that would be delayed until we could determine another public way to get at the convergence angle, and for us to get our source updated & released.

Backporting r45469 to relbr64 is the partial quick-fix, but doesn't help solve the root of the problem, and that patch would need to have the #ifdef __MINGW32__ stuff removed.

try r45789 in 6.5svn and r45790 in trunk.

rebuild and g.region -n needs to be tested, I am concerned about multiple definitions of the function causing problems on systems not using proj4-trunk.

thanks, +1 for backport to relbr64. Martin

I would really vote for this backport, 6.4.1 is knocking on the door...

Tested in 6.5 with proj-4.7.0, working fine here.

Also works for me...

universal dropping of projects.h backported to relbr64 in r45878.

fingers crossed..
