Any thoughts on this one Phil?! It doesnt actually kill the

Hi David,<br>
<br>
Great minds think alike, I just actually took a step further by
codesigning the module! Now I get a new error!<br>

This looks like I failed to link something...<br>
<br>
Anyway, I tried the static method and failed miserably, as in I
managed to compile NumPy and make a libnumpy.a which I then linked
against the application (via the LIBS variable in the .pro file),
but python couldn't find (or didin't try to load/know about) the
module. I would really appreciate a write up of this as I think
this may very well be the answer for me too, thank you.<br>
<br>
I'm doing this with NumPy 1.9.3 as well, also manually patched.<br>
<br>
Thanks you very much indeed,<br>
<br>
Rob<br>

While iOS does support dynamic modules as of version 8,
that support is extremely limited compared to most
platforms. I have not experimented with it yet, however
my understanding that dynamic modules must be compiled
as a framework (not just a shared library) and must be
properly signed, just like an app.<br>
<br>
</div>
For myself, I just compile NumPy as a static library
compiled directly into the executable. I can write up a
description of how I did this if you are interested ....<br>
<br>
</div>
Out of curiosity, are you using the latest version of
NumPy? (1.11) What did it take to get it compiled for
iOS? I am running version 1.9.3, but had to patch a few
files. I haven't looked into more recent versions yet, but
suspect patching is necessary still ... ?<br>

Having successfully built my app and NumPy and (bits of)
SciPy for Android, I am now trying it on iOS... And having
my usual struggle with understanding how to build/load
extension modules. I have managed to compile NumPy for iOS
and have the necessary .so files. I add them to the bundle
and then run the app and I get the following traceback:<br>
<br>
File ":/imp.py", line 243, in load_module<br>
ImportError:

Process 475 exited with status = 1 (0x00000001)<br>
<br>
I have no idea what this is telling me! It obviously finds
image, tries to load it and fails.<br>
<br>
Has anyone had any success is building and loading
extension modules with pyqtdeploy for iOS or any ideas on
where to go from here. I'm guessing I've compiled
something incorrectly but I have no idea what/how.<br>
<br>
All help gratefully received,<br>
<br>
Rob<br>
