Problem installing on MacOS 12.5.1

[jmizv]

I've followed the guide but when doing

pip install git+https://github.com/enzet/map-machine 

it gives:

Not sure where I have control over the parameter MACOSX_DEPLOYMENT_TARGET? Do I need to increse it to 12?

Hi, @jmizv!

Looks like this is an Xcode—clang-related issue, which I'm not familiar with.

Not sure where I have control over the parameter MACOSX_DEPLOYMENT_TARGET? Do I need to increse it to 12?

Some guys on Stack Overflow recommend this. Some also recommend export SYSTEM_VERSION_COMPAT=1. At least changing environment variables seems safe.

[enzet]

Could you please tell me, how you plan to use the project? If you are OK with SVG images and are not going to generate PNG tiles, I may create a special branch without cairo dependency. What do you think?

[jmizv]

Hi @enzet, thanks for reaching out. I'm not really sure how to use the project. I was just curios and tried to experiment with it. No real goal. So let me try your suggestions with the env variable.

Hey, @jmizv!

I've created a branch no-cairo without cairo dependency. This version of Map Machine does not support PNG tile generation (i.e., tile and server commands) but supports SVG file generation (i.e., render command) and everything else from the standard Map Machine version.

All you need to try this version is to add @no-cairo to the pip install command:

pip install git+https://github.com/enzet/map-machine@no-cairo

This version however still depends on GEOS library. Please, check whether there will be any problems with this.

Hope this will help.

Hi @enzet thanks! I've tried your suggestion but it does not seem successful:

[enzet]

Sorry, my bad. I forgot to remove a package from setup.py. It is fixed now. Could you please try one more time?

You may need to run pip uninstall map-machine if it was partially installed.

[jmizv]

Hi @enzet thanks, now it seems to have worked. At least the install command succeeded without error.

And even better:

user@MB IdeaProjects % map-machine render -b=2.284,48.860,2.290,48.865

This gave me a really nice SVG file. Thanks for your efforts 👍 I'm more than fine for the moment without any PNG support here.

[enzet]

Wonderful! Thank you for the issue. I supposed, that libraries could become a problem.
