kivy-iOS Build Fails - What am I missing?

[NFG]

So I am following the information to build an iOS app here:

https://kivy.org/docs/guide/packaging-ios.html

My app is extremely simple - A Carousel and some images, but unfortunately I am in a hurry to prove that Kivy is a feasible solution for requirements.

Frustratingly kivy-ios keeps dying with this error and I am at a loss since all the files reverenced are generated by kivy-ios.

Is there more prep that needs to be done?

Should I be trying to provide a manifest of some kind somewhere?

Is this some fault of my code?

I have no idea where to start. Can somebody push me in the right direction?

Okay, let's calm down and start from the beginning :-). What exact command have you entered? At what exact step of packaging did you get this error?

[NFG]

I assure you I am very very calm.

Actually that error finally came down to a directory with an @ in its name causing confusion in the script.

Now xCode tells me that the build failed:

Command /bin/sh failed with exit code 24

So I clean the build folder and build again.

then it says:

/Users/me/Library/Developer/Xcode/DerivedData/mediademo-fobokzlfwmkiheficeutnuqlvjzz/Build/Intermediates/mediademo.build/Debug-iphonesimulator/mediademo.build/Script-113D17E2153E3DB5001310A6.sh: line 2: /Users/me/Documents/Aquarium/kivy-ios/dist/hostpython/bin/python: No such file or directory

Python is missing? I find that hard to believe.

Yet none of that path is there after ... /dist/

[NFG]

So I determined that part of the problem was that the Xcode CLI tools were not installed correctly.

There is a disconnect there when running Xcode 8 with OSX El Capitan. There may be ways to make it work in El Capitan but I went ahead an upgraded to Sierra.

That fixed the CLI tools issue.

For the record the way to know if the CLI tools are wrong is to say

> brew doctor

Homebrew will tell you if the CLI tools are out of synch.

Now I did a fresh install of kivy-ios and rebuilt it. hostpython appeared in the directory. Hurrah!

Created my xCode project with:

../kivy-ios/toolchain.py create org.kivy.mediademo /Users/xxx/Documents/_Work/MediaDemo

This works

Open the project and build.

The first error is the same as before:

rsync warning: some files vanished before they could be transferred (code 24) at /BuildRoot/Library/Caches/com.apple.xbs/Sources/rsync/rsync-51/rsync/main.c(996) [sender=2.6.9]

Command /bin/sh failed with exit code 24

From what I can tell the missing files appear to be various jpegs, so maybe I can ignore this?

Just for fun: Clean the build folder

Build again

kivy-ios/dist/root/python/lib: No such file or directory

So at the moment there is nothing in kivy-ios/dist/root/ 

Is this looking for the same set of files located in kivy-ios/dist/hostpython/lib ?

Can I just do a link to these files or copy them? 

Or is some other nefarious business at work here?

Worth mentioning is that there are four fatal errors during the build and they are all very similar:

checking whether cpp computation of bit length in ftconfig.in works... In file included from conftest.c:6:
./ftconfig.in:149:10: fatal error: 'errno.h' file not found
#include <errno.h>
         ^
1 error generated.

[ZenCODE]

The line you posted for the 'create' command appears wrong. The docs clearly state you must be in the directory and run it using './toolchain.py create ...'. Try that?

[NFG]

Thanks,

This time completely reloaded again just to be superstitious.

Re-ran the install on all the dependencies according to the guide https://kivy.org/docs/guide/packaging-ios.html

All seems correct.

>> brew install autoconf automake libtool pkg-config

Warning: autoconf-2.69 already installed
Warning: automake-1.15 already installed
Error: libtool-2.4.6 already installed
To install this version, first `brew unlink libtool`
Error: pkg-config-0.29.1_2 already installed
To install this version, first `brew unlink pkg-config`

>> pip -V

pip 9.0.1 from /usr/local/lib/python2.7/site-packages (python 2.7)

>> python -V

Python 2.7.13

I copied the procedure exactly from the guide from git clone to open and play.

All other errors were eliminated but this most pernicious one:

/kivy-ios/dist/root/python/lib: No such file or directory

/kivy-ios/dist/root/ is empty. 

On a faint hope I Disabled Bitcode, necessary but not related to this.

The error is the same.

What should I be finding in that folder?

[NFG]

Can anybody tell me what is supposed to be in the folder /kivy-ios/dist/root/ after the Kivy build, or after xCode project creation?

For me the directory is empty. In the project it shows up under Resources as "lib" and marked red because it's missing.

What is this file?

I am thinking that this gets installed by this file here:

kivy-ios/build/hostpython/x86_64/Python-2.7.1/Lib/distutils/command/install_lib.py

My guess is that I can change an option and maybe force the point.

But haven't time right now to read through it.

Any ideas on what I might be looking for would be very helpful.

[ZenCODE]

The a python folder, with header folder further down. But I'm not sure how that would help you.

Please post the full output of the command "./toolchain.py build kivy"

[harryx...@gmail.com]

I encountered the same issue. Nothing in the folder /kivy-ios/dist/root. (the error is called PBXCp Error: .../kivy-ios/dist/root/python/lib: No such file or directory)
Also, in the project, under Resources, the file lib is marked red.

As mentioned, can't really help without the command and full output....
