trying to use on osx

[netskink]

Hello,

I tried to use this on osx. It failed. This is the workflow I used:

1. setup python using venv
   a. python3 -m venv venv
   b. source venv/bin/activate
   c. pip install --upgrade pip
2. make

It builds with warnings 247/248 steps and then fails in link step with the following output:

2 warnings generated.
[248/248] LINK gn_unittests
ERROR at //build/config/mac/mac_sdk.gni:34:5: Script returned non-zero exit code.

    raise Exception('No %s+ SDK found' % min_sdk_version)
Exception: No 10.12+ SDK found

I have xcode 15.4 and the clang command line tools installed.

I tried to hack up the code to accept the higher xcode version but in the end, the compiler flags failede on the link. 8-(
