Fail to create wheel for chaquopy-geos with chaquopy 16.0.0

Environment:
Python 3.11.9.0
https://github.com/ytremare/chaquopy-16.0.0

Requirements:
please find attach pip list result

Trying to build wheel for chaquopy-geos i get the following errors:
ld.lld: error: undefined symbol: __extenddftf2
ld.lld: error: undefined symbol: __multf3
ld.lld: error: undefined symbol: __addtf3
ld.lld: error: undefined symbol: __gttf2

Please find attach lld content. (symbols are indeed missing)

I confirm I get the same errors. Searching for the errors indicates that they're caused by libtool using the -nostdlib option:

• android compilation fails sqlite tauri-apps/tauri#6047
• [Bug]: Several configure&make packages give binaries with cannot locate symbol "__extendsftf2" termux/termux-packages#8029
• [Bug]: Rust compiling rusqlite fails in rust 1.66.1: error: undefined symbol: __extenddftf2 termux/termux-packages#14576

Something in the build system probably works around this by adding libgcc back into the link. But since the last time we built this package, we've moved to a newer version of the NDK that replaces GCC with Clang, and the corresponding library isn't called libgcc anymore.

Taking a step back, why are you trying to build chaquopy-geos at all? You haven't made any changes to it on your fork. Are you planning to upgrade it?

It's possible that a newer geos version already has a fix for this issue, since Clang is becoming more popular on all platforms.

Thanks for your response. I had a look at the issues you're referring to and was'nt very optimistic. To answer you question: My app uses cartopy, doing so , build.gradle calls shapely (which has no wheel for python 3.11) So I decided to build shapely and shapely needs chaquopy-geos. I 've tried différent options but no one succeeds,as the failure occurs at linking time my guess is the current is OK and there is no update to provide. One more question: I 've on my side few wheels availables and running well (eccodes, pygrib,cfgrib,cartopy) I never provided wheels to chaquo.com.pypi repository and not sure how to. Does it make sense to upload them even they are in python 3.9 (build was done under chaquopy14.0.2). Note: pygrib wheel is working but from my point of view unusable (too much slowly at least over Android) It take few minutes (around 10 mins) to open and read a file of 6 messages, a grib file (the ones I'm using contains around 100 messages). cfgrib providing equivalent features takes few seconds (let said 1 minute for 100 messages).

My app uses cartopy, doing so , build.gradle calls shapely (which has no wheel for python 3.11) So I decided to build shapely and shapely needs chaquopy-geos.

You don't need to build chaquopy-geos, you can download it from https://chaquo.com/pypi-13.1/. When you tried to build shapely, you should have been given a message telling you exactly that.

I never provided wheels to chaquo.com.pypi repository and not sure how to. Does it make sense to upload them even they are in python 3.9 (build was done under chaquopy14.0.2).

You can contribute a package to the public repository by making a PR. Here are some recent examples:

• Add zope.interface package #1014
• Added DepthAI package and required fixes #1059
• Implemented igraph #1196

Every recipe needs at least a meta.yaml file and a test script. Some of them will also need patches.

Follow the instructions in server/pypi/README.md to run the test script on at least one Python version and ABI, and mention in the PR which versions and ABIs you've tested.
