不存在/usr/bin/arm-apple-darwin9-gcc。iOS 9.1 SDK （clang）不知道该怎么。:(

[jdelman]

I was able to get it running on OS X El Capitan with Xcode 7 & the iOS 9.1 SDK.

See https://github.com/jdelman/python-for-ios and checkout branch arm64.

[Tatsh]

Cool except jdelman@83381dc#diff-46cb3d86e30c6dd7e235dbd05f49b19fR16 . Doesn't this make os.environ always have an empty dict? from os import environ; environ

I do not know if there is a good workaround without using Objective-C at this point. _NSGetEnviron() is not documented and environ (global char **) apparently does not work as expected on OS X and iOS.

With Objective-C, and telling the compiler to use that language for that file (-x objective-c, rename to .m maybe works too), you could call [[NSProcessInfo processInfo] environment] but you would have to convert the NSDictionary of NSStrings back to a regular char ** ('KEY=VALUE' for each).

NSDictionary *objectiveCEnv = [[NSProcessInfo processInfo] environment];
for (NSString *aKey in objectiveCEnv) {
    char *tmp = [[NSString stringWithFormat:@"%@=%@", aKey, objectiveCEnv[aKey]] UTF8String];
   // ...
}

[jdelman]

Good point, I hacked it together haphazardly & blindly without realizing
the environment meant... the environment - I don't really know what I'm
doing.

I fired it up after that and saw I also couldn't import math, or urllib2
(couldn't "import _socket").

Are you saying you'd replace crt_externs.h with that Obj-C code?

Nah, I think if char **environ works on iOS, otherwise it will just return NULL. But the code already checks for that. You only needed to remove the direct call to _NSGetEnviron() because it does not exist on iOS (anymore I think). Otherwise you are missing a link to libSystem (libSystem is supposed to have it).

[Tatsh]

Also with regard to some modules, I do not think all the modules worked in the previous build either.

[teknogeek]

@jdelman any news on this? Would love to get python working on iOS 9

[formoon]

Mark and wait for ios9 version

This one seems work for me, find this link from:
http://iphonedevwiki.net/index.php/Updating_extensions_for_iOS_9

Only install python it self may work, but I install all deb package.
need ldid -S /usr/bin/python2.7 first else will get kill -9 error.

[jdelman]

@formoon What model iPhone are you running that on? Is it a 32-bit (iPhone 5 and earlier) or 64-bit (iPhone 5S and later) model?

[formoon]

64bit iPhone6s.

I am getting the same error after the same steps on iPhone 6S 9.3.3

Building fixed for 9.3 but not everything works.

@jdelman I forked your repo and can build, however seeing 'No module named select' while trying to import subprocess. Any idea?

Seeing logs:

[Tatsh]

There is a ton of stuff to fix to make this work fully again (or usefully). Some of those are not fixable (easily) but most are. They require libraries to be present, some of which don't exist on Cydia. You really should go for modularism here and build those libraries as separate packages for Cydia and then build Python based on those. It will help many projects to have updated libraries.

[cclamb]

I was able to build a version for IOS 9 from jdelman's branch; is that going to be merged into this mainline? also, is anybody actively working these issues that @Tatsh references above?

[cclamb]

...also, this is a link to the DEB file I built and installed on 9.3.3 with the Pangu break:

https://drive.google.com/open?id=0B5vZIFDVHQ19d25KY2xlbUdLVzQ

Perhaps you guys could make this available as a release, with caveats?

[Tatsh]

@cclamb if you made any improvements, please provide a patch or set of patches.

[cclamb]

No, I haven't touched the code yet, but I was able to build the arm64 branch of the repo @jdelman forked; maybe he could submit a pull request? I could not build from master on this repo, which is why I'm asking.

I'm happy to pitch in, but I don't see any specific issues in the issue tracker than need to be fixed, though I see a few things alluded to here. Is anybody actively tracking these yet?

[Tatsh]

Well, jdelman@83381dc is not exactly the same as my patch. We need to merge these results. And then keep going. Also need to future-proof for iOS 10 in this effort. The code should compile for a non-jailbroken updated iOS 10 device, and still work with iOS 9.3.3, maybe 9.0.2 for those stuck behind.

[cclamb]

Ah, okay. So your patch isn't pushed. Do I just need to apply the patchfile above?

[Tatsh]

Compare Tatsh@1525f3d with jdelman@83381dc and see what's new and what's improved in @jdelman's version. He seems to have a new patch there for the environ module.

Also note full paths (like /usr/bin/sed) in mine as the Makefile is for OS X, so we force the use of BSD coreutils instead of GNU. OS X comes with BSD, not GNU. Supporting both with conditionals in the Makefile could be an option in the future.

[masbog]

@Tatsh always get error on compile for 64 bit from your repo,

configure: error: in `/Users/masbog/GitHub/python-for-ios/Python-2.7.6':

configure: error: C compiler cannot create executables

See `config.log' for more details

and config.log said :

any suggestion for fix it? i use xCode 8.2.1 ☹️
