Issues installing klayout with pip on macOS related to libpng

[qpavsmi]

Hardware: Macbook Air, Apple M1 chip
System Version: macOS 13.2.1 (22D68)
Kernel Version: Darwin 22.3.0

Tried installing libpng using homebrew and from their sourceforge, same error.
klayout 0.27.9 installs fine, but we need to have 0.28.* working to make use of QTless features.
Full pip install klayout printout below, relevant parts are with # include <png.h>

pip install klayout

  ERROR: Failed building wheel for klayout

[qpavsmi]

Also tried to install from the wheel klayout-0.28.5-cp311-cp311-macosx_10_9_x86_64.whl and it says ERROR: klayout-0.28.5-cp311-cp311-macosx_10_9_x86_64.whl is not a supported wheel on this platform., I presume due to the wheel supporting macOS versions 10 and 11 while my version is macOS 13.2.1

Hello @qpavsmi , very sorry about this. This issue was already reported in #1265 and fixed in a couple of PRs. It will get sorted out when 0.28.6 is uploaded to pypi. Unfortunately version 0.28.5 has this defect. If you need png, one workaround is to install from source. If you don't, I recommend installing a previous version from pypi.

[klayoutmatthias]

I'll publish 0.28.6 soon. Next week latest.

[qpavsmi]

Thank you for the quick response and for pointing to further discussion, this cleared up the nature of the problem for me since I'm not super familiar with the Apple platforms but am interested in providing mac support for our product.

Excited to see the fix so soon.

[klayoutmatthias]

0.28.6 is out. Please reopen if the problem still persists.
