[Bug] error in compiling main GRASS 8.6 g.proj

[cmbarton]

Describe the bug

I just now tried to compile GRASS 8.6 on my Mac using the built in Mac build scripts. These have worked like a charm before. But this time I got an error in g.proj.

I switched to the appropriate folder and did a make

(base) cmbarton@macbook-pro grass % cd /Users/cmbarton/grass_source/grass_dev/grass/general/g.proj

In case it is helpful, here is the error from the main build output:

[cmbarton]

I've completely re-cloned the source code as of today (22 June, 4pm MST) and still get these errors

[echoix]

Your log excerpt only shows a part of incremental build, of only the docs part. Did you start from a fresh build tree, such as no older compilation artifacts exist and would be (ABI) incompatible?

[cmbarton]

I did delete the earlier (working) build. Did this twice. Today, I completely replaced the source code too. And the build does a distclean too

[cmbarton]

I put in everything for g.proj. From the main build, I just put in the section before the error

[echoix]

If it complains that your proj version is too old (or the database, whatever that means), can you just get a newer version of that dependency?

[nilason]

(base) cmbarton@macbook-pro grass % cd /Users/cmbarton/grass_source/grass_dev/grass/general/g.proj

It looks to me you're trying the build-script with anaconda installed and active (effectively building a conda environment within another conda environment), that is bound to lead to conflicts.

[cmbarton]

I've always had anaconda installed. And of course used it for the initial work on building GRASS that way. It has never caused any issues because the GRASS conda installation has always been contained to the GRASS app.

The only things that have changed since I last built 8.6 is that 1) I have a newer MacBook (M5 instead of M2) and 2) the OS has been updated to 26.5.1

[nilason]

I've always had anaconda installed. And of course used it for the initial work on building GRASS that way. It has never caused any issues because the GRASS conda installation has always been contained to the GRASS app.

It most likely worked for a while, when the pinned dependencies in the build script, were the latest available. Now, probably you have 9.8 in your conda environment, but the pinned version is currently 9.7.1. See the error message:

proj_get_authorities_from_database: /Applications/anaconda3/share/proj/proj.db contains DATABASE.LAYOUT.VERSION.MINOR = 2 whereas a number >= 6 is expected. It comes from another PROJ installation.

[cmbarton]

Hmmm. It's been awhile since I updated anaconda, but I do so periodically. I did not intentionally install a newer proj. But of course it could have been installed as part of an installation of software in Anaconda.

Suggestion as to what to do about it?

[cmbarton]

Would this be the way to deal with this?

./macos/build_grass_app.bash \
--update-conda-stable \
--conda-file ./macos/files/conda-requirements-stable-arm64.txt 

[cmbarton]

That didn't work. But I did find out the version of proj I do have installed via anaconda is 9.1.1, an older version than the one called for in the GRASS script

[cmbarton]

should I just install proj 9.7.1?

[cmbarton]

I deleted Anaconda and GRASS 8.6 installed fine with the script. I still think it's a bit odd that the build scripts stopped working when they had worked before--especially considering I had not apparently updated or changed my Anaconda installation.
