statically linked GDAL 3.0.0 / PROJ 6.1.0 on OSX

[edzer]

See also #79, #327.

After building GEOS with:

CC=clang CXX=clang++ ./configure --disable-shared
make
sudo make install

then building and installing PROJ 6.1.0 with:

CC=clang CXX=clang++ ./configure --disable-shared
make
sudo make install

then building & installing GDAL 3.0.0 with:

CC=clang CXX=clang++ ./configure --disable-shared --with-proj=/usr/local --without-geos --without-pg
make
sudo make install

I was successful building an OSX static binary package for sf using

R CMD INSTALL --dsym --build --configure-args='--with-proj-lib=/usr/local/lib --with-proj-include=/usr/local/include --with-proj-share=/usr/local/share/proj --with-proj-data=/usr/local/share/proj --with-data-copy=yes' sf

There's one more patch to sf's configure needed to make this work (following).

@rsbivand please review these changes to rgdal's configure.ac: https://r-forge.r-project.org/scm/viewvc.php/pkg/configure.ac?root=rgdal&r1=831&r2=834

(still some debug noise in there.) Turns out I had to change a test for proj.db to use C++ rather than C, and link with -lsqlite3 on OSX (this is the noise Brian referred to). This works for me on ubuntu with both GDAL 2.x/PROJ 5.x and GDAL 3.0.0/PROJ 6.1.0.

Thanks. Are we now assuming that if PROJ 6 is present that libsqlite is present, or do we need to test for that too?

Do I need to release this version soon, or is R-Forge OK for now?

No urge for this until Simon's build train for OSX-CRAN migrates GDAL and PROJ...

[rsbivand]

Have updated the proj4.org URLs to proj.org too, check had started complaining.

Some great progress going on here; a message from Brian Ripley:

I have put binary packages on CRANextras for lwgeom rgdal rgeos sf built with GEOS 3.8.1, GDAL 3.1.0, PROJ 6.3.2.

Install with (e.g.)

options(repos="https://www.stats.ox.ac.uk/pub/RWin")
install.packages('rgdal', type = 'binary')

(This needed a development version of the rgdal sources.)

This is just to allow early access: it is planned to use these versions of the libs on the CRAN builders soon (but they do need package updates, e.g. for rgdal and proj4).

These are all using static libraries to make these self-contained.

(In case anyone is wondering why not PROJ 7 -- that would need unreleased changes to the PROJ and GDAL sources and changes to many CRAN packages.)

Please try these out and report success/failure!

Do not complain about rgdal issuing warnings (even annoying false positives), they are there to alert users further away from development that new transformation mechanisms may compromise their work.
