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

Wed Feb 9 07:43:46 PST 2022

I posted a note in Homebrew/discussions. The problem seems to be in the json api link -  /api/formula/gdal.json<https://formulae.brew.sh/api/formula/gdal.json>
Which includes proj at 7 rather than just proj.

Hopefully whoever can change formulas will see this and fix it.

Well - the Homebrew formula for GDAL 3.4.1 seems to mandate Proj 7 https://formulae.brew.sh/formula/gdal

That is strange - since the Conda package works on Proj 8! I don't know who supports the Brew packaging - I don't think it is core team since Homebrew is not listed on the installation page.  https://gdal.org/download.html

I must admit that is why I use Conda on all platforms - it is "generally" more up to date and being an environment manager and not just a package manager it manages cases like this a lot more robust.

Subject: does GDAL require proj at 7?

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

Warning: No available formula with the name "proj at 7" (dependency of gdal). Did you mean proj?

This similarly named formula was found:

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!
Jerry
