Tries to load libpq.5.dylib under BigSur

[bjoernbos]

After upgrading to BigSur, I am getting an error message when loading gdalcubes:

> library(gdalcubes)
Fehler: package or namespace load failed for ‘gdalcubes’ in dyn.load(file, DLLpath = DLLpath, ...):
 kann shared object '/Library/Frameworks/R.framework/Versions/4.0/Resources/library/gdalcubes/libs/gdalcubes.so' nicht laden:
  dlopen(/Library/Frameworks/R.framework/Versions/4.0/Resources/library/gdalcubes/libs/gdalcubes.so, 6): Library not loaded: /usr/lib/libpq.5.dylib
  Referenced from: /Library/Frameworks/R.framework/Versions/4.0/Resources/library/gdalcubes/libs/gdalcubes.so
  Reason: image not found

Apparently, it cannot load libpq.5.dylib, although the installation of gdalcubes works fine.

I've seen similar issues with sf (e.g., r-spatial/sf#1536), pointing towards some changes in BigSur. Does gdalcubes needs to be adjusted as well?

Thanks for reporting. I think this is exactly the same issue as with sf that was fixed in R-macos/recipes#14. Have you tried to reinstall gdalcubes from CRAN?

[bjoernbos]

Thanks for your suggestion. I needed to reinstall Xcode Command-line Tools (xcode-select --install) and then install gdalcubes from source again (install.packages("gdalcubes", type = "source")). Now it works.

For what it's worth, I got the same error and it was resolved by.

brew install libgit2
brew install udunits
