[GRASS-user] Multiple errors building Grass 7.7svn

Wed May 22 09:01:47 PDT 2019

Thanks for that info. So would a suitable strategy be to try re-synching  Grass from git, then compiling and building with proj 6.1, and if that fails, try the proj 5.9.3 release?

be aware that GRASS might compile with PROJ 6, but it is not working, too much has changed from PROJ 5 and all those changes are not yet considered in GRASS. Most importantly, coordinate transformations might produce wrong results.

Furthermore, GRASS will most likely not support PROJ 6.0, only PROJ 6.1+, because of bug fixes and important new functionality.

It depends when you updated master the last time. If in doubt, git pull again.
