Re: Qt build problems after bump to 5.12.7

[John Soo]

Hi Guix and T G-R,

I think i verified that the upstream patch will fix the failing
freecad build at least.

guix refresh qtbase --list-dependents reports 377 dependents on qtbase though.

So that leads to option 1.

My only problem is that I am not sure which packages are failing
because of the bug.  Any idea how to figure it out?

Thanks,

John
