Mac version

[JakubReha]

Hi, I am trying to compile the package on mac but I get library errors. Is there a version that works for mac? Alternatively is it possible to compile the package on linux/windows and then use on mac?

Could you paste the errors here? I conjecture a libjpeg part related to menory management for mac.

Thanks for pasting the error message here. I think I need to test the compilation on mac. I have no mac machine now. So, I will test it at my company tomorrow. Wait for a day please.

@JakubReha I've added and tested supports for macOS. Could you please test the JpegIO package on your machine?

The installation went fine, but I am getting this error when trying to import jpegio: File "/Users/kuba/Downloads/jpegio-master/jpegio/init.py", line 6, in from .componentinfo import ComponentInfo ModuleNotFoundError: No module named 'jpegio.componentinfo'

[JakubReha]

if I use this in the init.py: import pyximport pyximport.install()

it seems to solve the problem for the the ComponentInfo, but then I get:

@JakubReha From which directory did you import the JpegIO package? You should not import the package from the repository directory. If it is the case, try importing the package in another directory.

[JakubReha]

Thank you but now I get this: zsh: illegal hardware instruction python

[dwgoon]

@JakubReha How did you install JpegIO? Did you use the *.whl file or compile? Could you tell me your macOS information (version, architecture, etc)?

[JakubReha]

I was using the wheel, now I reinstalled it using only the compilation and it works. Thank you very much

@JakubReha That sounds great! :)
