[arch-general] Segmentation fault when trying to install a self-created package

[Peter Nabbefeld]

Hello,

as the meshroom builds (from AUR) don't work for me, I tried to create 
my own package by modifying the PKGBUILD file of the meshroom-git package.

This results in two issues:

1. While creating the package using makepkg, the whole git repository is 
downloaded - that's okay, of course. But all built artifacts seem to be 
contained in the resulting package file. As a git build shouldn't be 
"static": How can I create a build file for automatic downloading and 
building from current repository?

2. When installing the created package (pacman -U) and trying to start 
Meshroom, I get: "Segmentation fault (core dumped)". It seems, there's a 
problem with Meshroom's private shiboken2 installation:

Does somebody have an idea, what I could change?

Kind regards,
