rgdal as of 2017-01-01 does not compile

[grssnbchr]

Environment:
Ubuntu 18.04
gcc 7.3.0
GDAL 2.2.3, released 2017/11/20

Problem
Up until rgdal 1.2-6, compilation fails in ogr_proj.cpp.
The rgdal version as of 2017-01-01 is 1.2-5

A fix was introduced in rgdal 1.2-7, from the changelog:
2017-04-14 21:38 edzer
* src/ogr_proj.cpp: address gdal 2.2 compile errors

Possible workarounds:

• Install an old gdal version, e.g. compile 2.1.3 from source, according to here (tested)
  • sudo ./configure --with-libtiff=internal or compilation fails
  • remember to run sudo ldconfig after successful compilation and installation
  • if you want to uninstall gdal again and install the latest package from apt, follow these guidelines, i.e. sudo rm -rf /usr/local/bin/gdal* and sudo rm -rf /usr/local/lib/gdal* and sudo rm -rf /usr/local/lib/libgdal* and sudo ldconfig.
• Bump package date to 2017-05-01; by then, 1.2-7 was released (untested)
