Hi Michael,

> 1. Some Homebrew bottles have the dynamic library paths hard coded to /opt/homebrew instead of @rpath.  If you try to use install_name_tool

yes, i already see this information while investigating with HomeBrew.

> You need to run the codesign tool to update the signature, 

yes, the script do it here : 

https://invent.kde.org/graphics/digikam/-/blob/master/project/bundles/homebrew/04-build-installer.sh?ref_type=heads#L514

because binaries are not compiled on the computer, but taken from a homebrew
cache on the web ?

Well i know that already with Macports. On my MacbookPro 2015, this take around
8 hours, especially about clang/gcc/qtwebengine build.

Interesting tune to know...

Right. The install path must be /opt/digiKam._arch_ here :

https://invent.kde.org/graphics/digikam/-/blob/master/project/bundles/homebrew/config.sh?ref_type=heads#L63

as i do with Macports already :

https://invent.kde.org/graphics/digikam/-/blob/master/project/bundles/macports/config.sh?ref_type=heads#L65

> 2. Not all of the needed libraries are being packaged by 04-build-installer.sh.  This is slow work going through and finding the libraries that are missing.

Why not all libs ?

> 3. I think not all the updated binaries are being re-signed by codesign.  Again, it's slow work going through them.

Same Q ?
