Build error on Arch

[nd925a]

Hello,

Trying to do a fresh install on Arch and got the following error using both the 4.12.3 release (which is pulled by a PKGBUILD in the aur) and current git repo source.

I'm gonna continue playing with it, but I'm more than rusty at coding. If someone knows what to do about it I'd appreciate it.

Thanks

GCC version?
libusb version?

My gut feeling, and Massimo can probably confirm ... you need libusb0. In my Linux Mint VM, I have libusb-0.1 and libusb-dev (both of which are version 0.1.12). I also have libusb-1.0 package installed, but I do not have the corresponding dev package for libusb-1.0, so my build is against the 0.1.12 version of the library, which works fine. In the debian/control file, it specifically says libusb-dev >= 2:0.1.12. I'd suggest trying the 0.1.x version of the package and see if that's better.

Look like Qt issues to me, not QLC+ related

[edogawa]

Can't help with v5 beta but I have a patch for the entecusbdmxpro plugin /QMutex problem, which I stumbled into a while ago.

Usually I try to send such deprecation fixes upstream vie github pull request, this time I forgot for some reason.

I append my patch here, it's trivial, and maybe Massimo can merge this to master simply from picking it here? otherwise I'll PR.


EDIT: The patch in its current form is just a quick workaround for Qt 5.15.x users. It doesn't check for older Qt versions and modify the mutex call conditionally, for a proper pull request I really should add appropriate preprocessor handling.
