Hi,
desperately trying to get rgdal installed on R > 3.5.x with GDAL 2.3.0
on macOS High Sierra. I am aware of the discussion that a suitable
compiler is needed since GDAL > 2.3.0.
I've set
CC=clang
CXX=clang++
PKG_CXXFLAGS= -stdlib=libc++ -std=c++11
In ~/.R/Makevars as suggested here https://github.com/r-spatial/sf/issues/726
Does anyone actually know that this is a solution or rather the problem?
Check:
$ R CMD config CXX
## clang++ -std=gnu++11
## for me with an R-devel clang build on Fedora 28
Run this and/or ./configure in the unpacked rgdal source tarball and
report the CXX value. Is the issue advice wrong, and CXX should be
'clang++ -std=gnu++11'?
I have no access to OSX (and no wish to have access) - the OSX users need
to do a full bisection and not guess what is happening.
The automated checking during the rgdal installation shows that C++11
support is available. But still it complains about a lacking C++11
support.
No, that is coming from code in GDAL itself, as you can see. You need to
establish which --std= is actually needed.
I've searched the web but could not find anything helpful. If I've
overlooked something, please just point me to the link.
Searching the web only confirms that there is very little signal there -
search the source code instead, and bisection (which settings worked for
which versions, and which changes provoke the issue)? Is for example the
CRAN R binary reporting a different R CMD config CXX from your
homebrew-built R?

From the GDAL 2.3.1 source at the given line number - your __cplusplus
from homebrew's value needs checking:
/* MSVC fails to define a decent value of __cplusplus. Try to target
VS2015*/
/* as a minimum */

Fallback is the CRAN OSX binary for rgdal 1.3-4 (with the addition of proj
datum files as posted yesterday, or Kyngchaos (as on R-sig-mac).
