rsgislib 2.1.20140825_1 +python27 build failure

[ForTozs]

I am unable to build rsgislib with MacPorts. I am getting the following error:

I'm not sure if it's related. But I've been told that the default rsgislib branch is compatible with gdal 2.x now. I tried updating the portfile but I still get a similar error.

I'll start by saying I know nothing about rsgislib or GEOS, but I do know how to often build things on MacPorts that won't initially build.

The error in your build file seems to be this:

info:build /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_gis_rsgislib/rsgislib/work/9135d61/src/utils/RSGISGEOSFactoryGenerator.cpp:34:27: error: calling a protected constructor of class 'geos::geom::GeometryFactory'

6662	:info:build                 delete geomFactory;

6667	:info:build 2 errors generated.
6668	:info:build make[2]: *** [src/CMakeFiles/rsgis_utils.dir/utils/RSGISGEOSFactoryGenerator.cpp.o] Error 1

And this issue <​https://github.com/osmcode/libosmium/issues/168> suggests that GeometryFactory changed in GEOS version 3.6.0 in a way that broke some other things with what looks like a similar error, and warns there may not be a fix coming for this.

So one thing that would be fairly easy to try and would not take much time would be to roll back to a version of GEOS < 3.6.0, and if that installs for you without issue, perhaps rsgislib will build against that older GEOS for you, while you wait to see if rsgislib gets fixed or updated someday.

If you already have older versions of GEOS installed on your system, you can sudo port activate the version you want.

If not, you would have to install and then roll back a MacPorts git repo to that commit, which looks to be a commit somewhere around this one:

summary geos: bump to 3.6.0

I hope this is helpful.

This is helpful indeed. Thanks.
