Same as #150. Unfortunately, I can't reproduce it and have no idea what is causing it. :( In addition, on a normal install, the pre-compiled header should be build as part of the install process, not on first use.

I was also surprised that the pre-compiled headers were built on first use. Is there a way to build the headers before importing cppyy?
The install process already does that. You should be able to find a .pch
file in /Users/yzhang/Library/Python/3.11/lib/python/site-packages/cppyy_backend/etc
. But otherwise the process of building the PCH is the same as cppyy uses when it fails to find it.
Have you tried installing with conda
(WORK) $ conda install -c conda-forge cppyy
(WORK) [current compiler] $
this installs a different compiler, might have better luck

I tried to install with conda, but that was for cppyy 2.4.0. Is there a way to install cppyy 3.0.0 with conda?
I'm trying to complete the github workflows that were contributed (https://github.com/wlav/cppyy-backend/pull/8). Although it doesn't run all yet, the building of the Mac wheels does and I'm finding that those wheels do NOT work on my laptop. In a way, that's not good, but it may also help me to get some fixes for upstream as it's the only reliable way that I have to break things on my box.
Should all be good now with release 3.1.0. Feel free to reopen if you find otherwise.
I'm trying to use cppyy on my Mac mini M2 pro (Mac OS Ventura 13.3.1). Following the documentation, I ran
python -m pip install cppyy
and then want to test the installation with python, but I got the following error messages (only the top messages are shown):

What could be the reason for these errors? Any hint? Thank you very much!
