Issue installing sf on Ubuntu with GDAL 3.2?

[dblodgett-usgs]

I'm working on testing COG endpoints and would like to try stars against a COG with GDAL... at v3.1, GDAL keeps trying to access a COG as an OPeNDAP endpoint so I figured I'd try getting updated to 3.2 as they introduced the ability to specify the format. (not sure sf actually passes the parmeter, but figured it was worth a shot!)

In the process, I found that I can't get sf to install cleanly on this setup. See the Dockerfile below. It makes it all the way to the end then fails with an error I don't see any reference to.

Any ideas? Error is: undefined symbol: proj_get_units_from_database

We saw this problem in rocker-org/geospatial#31 . sf is being tricked into believing PROJ 7.2.0 is available, which kind of it is, in /usr/local/, but this is an instrumented version (I believe) to only serve GDAL and not stand in the way of applications linking to the other PROJ (in /usr/, 6.3.x). So the configure step makes sf believe 7.2.0 is there, but the link step doesn't resolve the symbols (as the /usr/local/lib/libproj*so renamed them to cater GDAL).

My suggestions are either to not build on osgeo:gdal images, or maybe install PROJ 7.2.0 properly on it in /usr/ (you'll probably break GDAL if you overwrite PROJ in /usr/local without renamed symbols). Why *#$ does this image have PROJ 6.3.0 in /usr?

oh wow. OK thanks for the thorough explanation! I'll look for another way to get GDAL 3.2 for experimentation. Looks like https://github.com/perrygeo/docker-gdal-base has it.

[dblodgett-usgs]

Nope, same deal over there. sigh. One day, this proj transition will settle down.

@Robinlovelace what do you suggest?

Hi @dblodgett-usgs, definitely a good question and one that has confused many people. I suggest using the rocker/geospatial:dev-osgeo container, e.g. as follows:

docker run --rm -ti rocker/geospatial:dev-osgeo R -e "library(sf)"

Running that gives:

See rocker-org/geospatial#31 and the rocker documentation for further info. Does that help? Hope so!

Nice! I'll give it a go. Thank you.

I did get this working and have been able to test a COG file from stars. Very cool that we will have access to this out of the box on GDAL 3.2.
