7 months ago it looks like there are some header files missing, like curses.h. Maybe some stuff didn't get downloaded and the build system thinks it did (caching). Maybe you can clean out the build directories and start over. I think "toolchain clean" might work.

Thanks for the reply. I did as you suggested, however the output is the same as before and the toolchain status remains unchanged. The error log suggests that 3 packages (_gdbm, _tkinter, and ossaudiodev) weren't found and therefore not built, however I found all 3 within the 'Modules' folder located inside the python3 folder belonging to the main build folder. I don't suppose that could be the root of the problem? I've never used the C language or C++ language so my knowledge with those files is limited
Edit: In case it helps, I tried toolchain clean and then toolchain build kivy in both the regular terminal and then the Rosetta Terminal, both resulting in the same output and same toolchain status output

7 months ago I am facing that issue on a M2. Got it working on a M3. Both with kivy-ios 2024.3.17 Cython 3.0.0 Python 3.11.6 .
I suspect that the problem is that I did not manage to proper purge all old kivy-ios and toolchain components. - There was a lot of installing, distcleaning and uninstalling in different directories involved - at some stage I had conflicts due to two build folders in different directories. Also facing buggy behaviour needing to rename XCode while the build, which is not an issue on my M3 with a cleaner installation.
Here a cut-out from the logs:

Not sure what you mean. For pandas and fastapi there are no recipes atm. I would do the pandas calculations with numpy and look for a pure python api package which one can install with for example: toolchain pip install py-pure-client. Numpy did work for me toolchain build numpy... Once this problem is fixed.

I am religiously cleaning the three folders @tcaduser mentioned. With toolchain distclean as well as by hand - didn't help. Pip uninstalled kivy-ios, deleted the whole venv - still the same issue.
It doesn't make sense that the problem is related to the python version. The whole setup on the M2 worked before I decided to start everything from scratch due to another issue.
Anyway:
My xcode-select versions on both computers is 2405, python 3.11.6 & 3.12.2, XCode 15.3 & XCode 15.1, the xcodebuild -showsdksoutput is the same as above.

I am also getting the same compiler warnings as @Retr0Hax894 for sqlite and xmlparse.

7 months ago Went on a rampage - reset with xcode-select -r, deleted xcode, deleted CommandLineTools, toolchain distclean, deleted the virtual environment, reinstalled all - same output. 😔 As last resort, taking the dist, .cache and build folders form the other computer worked.
Plus, I could substitute the old workaround of renaming XCode with a new workaround of changing the path from
% xcode-select -p
/Applications/Xcode.app/Contents/Developerafter creating the ios repository and before the first XCode build with
sudo xcode-select --switch /Library/Developer/CommandLineToolsThat behavior started once I installed kivy-ios from the master branch before the last release and build matplotlib with toolchain.
Not sure if those two issues are related, but it seems to me as if some left-overs of the old kivy-ios installation or toolchain builds are being missed while the uninstalling.

6 months ago I just tried to build Kivy again and noticed something interesting in the build logs. Sadly it's too far into the build logs to retrieve, but it was roughly something like: downloading (link to python 3.11.6) (I do remember that it was specifically version 3.11.6).
I have python 3.12 downloaded. While I can download and use 3.11.6, a PEP document bringing forward the idea of separating python packages based off of the package manager they're installed from, and labelling such packages as being 'externally managed', was put forward to Homebrew. As of February this year, the idea was implemented so that packages were handled per the package manager that installed them, and as such only python 3.12 would be installed from Homebrew so that this change would be universal for all Homebrew users. So while I could change version, it wouldn't work alongside Homebrew. Would changing the python version to be downloaded when building help these python errors?

It took a good while to remove the libb2 package due to various dependencies, but after solving that it has finally built! I don't think I can thank you enough, it's been a very frustrating 3 weeks. I'm glad it's now fixed and I hope this will help anyone else that's stuck in the future.

Worked for me as well. Still puzzled to why, since libb2 is on that computer since ages and the build ran many times through. But happy it's solved. Thanks @tcaduser

6 months ago I'm glad it worked out for everyone. It is very surprising that brew can interfere in that way. I've always made sure that brew stays out of my PATH, and used the macOS python instead of the one from homebrew.

5 months ago thanks for this! anyone knows why uninstalling libb2 this solves it?
Update: I get:
Error: Refusing to uninstall /usr/local/Cellar/libb2/0.98.1 because it is required by ffmpeg, gstreamer, libarchive and tesseract, which are currently installed.
so it doesn't sound like a viable solution
do we have to set CPPFLAGS,CFLAGS,LDFLAGS? if so, any docs on that? I'm on mac intel

One thing you can try is to make sure homebrew is not in your default PATH. Then its version of python packages cannot be found. This could be interfering with all of the other version of python that kivy-ios using.

5 months ago I would look in your .zshrc .bashrc or .profile to make sure that homebrew is not there.

5 months ago but isn't homebrew supposed to be the most used package manager on mac? if it's not on PATH, then how would I access it when I want to install anything? I'm a bit confused
or is it more like a workaround to remove it from the PATH temporarily only for the running program (Pycharm in my case)?

5 months ago You can type the full path to whatever tool you want in the homebrew bin directory. I am just giving something to try. It looks to me like one of the recipes is looking for libbb2 and by finding it in your homebrew installation, is messing up. It is impossible for the compiler for the iOS to use a library compiled for macOS.

3 months ago brew uninstall libb2
Remove the following folders build dist .cache
.cache is hidden
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
/usr/bin/xcodebuild -showsdks
toolchain build kivy
and tray

3 months ago What I don't understand is that kivy-ios compiles a hostpython, which should run instead of the one from homebrew? Perhaps the Homebrew python environment is polluting the hostpython environment?
Versions
Describe the bug I have 3 folders which I'm using for this project: A folder dedicated to the python virtual environment, a folder dedicated to the Kivy Builds, and the folder containing the pre-build Kivy app in python. I'm currently trying to toolchain build python3 and Kivy. Regardless of what I try to build, however, the output (as shown below) is always the same.
To Reproduce This is the first time I've ever tried to build a Kivy application for iOS, so I'm afraid I don't know how to help reproduce the problem. Here's the
toolchain statusoutput:and
toolchain buildoutput (same output regardless of what is building).Expected behavior The expected behaviour is a completed build, allowing me to convert my python code into an Xcode project.
Logs The following was produced with the command
toolchain build python3however the response is very similar if not identical to the response from the commandtoolchain build kivyortoolchain build python3 kivyAdditional context Currently using Cython==0.29.36 however I also tested it with the current version of Cython==3.0.0 (changed to 3.0.9 earlier today but didn't change the output). Kivy.org iOS page states that Cython=3.0.0 is required, but pip says Cython==0.29.36 is needed for Kivy-ios, so I don't know which to use. I've tried separating the folders from other code files. All three are isolated on my desktop and still no change. After activating the venv, all three folders clearly use the python environment located in the environments folder.
Any and all help is greatly appreciated thanks in advance! TLDR: Issue resolved by making sure libb2 installed by brew(due to packages like ffmpeg is interfering, remove it! or make sure it does not get picked in path.)
