Success!
This morning I upgraded a Mac to OS 10.13.5 (the so-called High Sierra
version), then
- Installed R 3.5.0 from CRAN (installed ever 3.3.x)
- Installed sp 1.3-1, rgdal 1.3-2, rgeos 0.3-28, also sf 0.6-3, from the
CRAN binaries that are now available
- Ran my personal test suite, which exercises the kinds of tasks I
perform with those packages
All tests succeeded.
Thanks for reporting - especially on your own test suite. We do what we
can to cover typical use cases, but independent testing in production
settings is reassuring for everybody. We're expecting more PROJ-based
changes later this year and next year, so it is great to have external
test sets to be able to check where any changes in output are coming from.
This is an encouragement to other users whose production depends on R
packages using GDAL, PROJ and/or GEOS to follow this example and keep a
script handy to test your use cases, and a history of output files with
which to compare (diff). We don't worry about changes in the EPSG
versions, but by next year they may be properly anchored too (changes in
PROJ may include reference system definitions with timestamps).
I forgot to control the order of installation, so I don't know if I
installed sp first, as advised. But I expect that with the binary
versions it doesn't matter.
Right, the binary builds use the sp version on the build platform.
Best wishes,
Roger
(I don't think it matters for the above, but I also installed the clang
and gfortran version provided on CRAN's Mac "tools" page, and
successfully compiled some source packages that require fortran, and
others that require C).
Thank again for all your work
-Don

There are new releases of sp, rgdal and rgeos on CRAN. Please install sp
first, then the other two, which link to the installed sp. They all
address so-called rchk issues, which have not so far been a problem, but
might have become more fragile as R's internal memory management is made
even more efficient. This involves compiled code using memory allocated by
R to be freed by R's garbage collector, which has to know if an object is
still being used. Tomas Kalibera, the author of rchk, helped resolve and
explain the issues encountered - what was good coding practice fifteen
years ago isn't always still good practice.
In addition, the earliest versions of GDAL and PROJ with which rgdal will
work have been updated, and set to PROJ 4.8.0 and GDAL 1.11.4. The current
released versions of PROJ and GDAL are to be prefered, as bugs have been
fixed and new features and drivers introduced. A check has been put
in place to trap attempts to install rgdal without a C++11-capable
compiler when the GDAL version is >=2.3.0 - which requires C++11. rgeos is
ready for the forthcoming version of GEOS.
The CRAN team has also been very supportive of our efforts to bring
compiled code in these packages into rchk compliance.
Please get in touch if you see any loose ends in these releases.
