• Changes in steup.py #80

Why was this required — are you using Python 3.7?

[sashkab]

This is being tracked in internal-1028.

@sashkab Yes using 3.7

I finally go it working after removing all the CFLAGS as recommended by @sitsang

Now every time I sun >pyq I get the following error

Most likely you're using 64-bit python with 32-bit kdb+.

You need 32-bit python in order to use 32-bit kdb+.

[sashkab]

Warnings which were treated as errors reported above were resolved and will be part of 4.2.0 release. Second part is seems to be user error(32-bit kdb+, 64-bit Python), therefore I'm closing. If you still have issues installing PyQ on macOS — please open a new issue.
