[gdal-dev] does GDAL require proj at 7?

[Gerald Nelson]

I indirectly make a lot of use of GDAL which makes a lot of use of proj. I do all this on a new Macbook pro with Apple Silicon. I manage these things with homebrew. It was a tiny bit complicated to get homebrew running to take advantage of the new silicon but I’ve been doing that successfully for a month or so.

At some point in the past I installed proj at 7 from homebrew. That’s now deprecated but I can’t seem to kill it on my system. Lots of brew uninstall and install/upgrade commands. I used locate in a terminal and attempted to delete all the files with proj at 7 in their names. I’m currently have this set of exchanges


gcn at MacBook-Pro-M1X Cellar % brew install gdal

Dropped refs/stash@{0} (cf00995d0160fc9ed0889b664973b1c75a4a5925)

At this point I’m stuck on next steps. I suspect this is not a gdal problem per se but something in homebrew I’m not understanding.

Any advice greatly appreciated!
