I just build it on a Ubuntu derived 64bit system. It compiles fine.
Great! Thanks for reporting back. Do try it out, and share your
experience. To me, the implementation of the Burt/Adelson Algorithm is a
major breakthrough.
Before testing further I did the same on my Debian 10 buster armhf
Raspberry pi 4. Now it ends in error.
Don't put too much effort in it. The rpi4 is my server, but I just
wanted to test if it would compile there (and then test it via tightvnc).
pv is currently intel/AMD only, the Raspi uses an ARM processor. I'd
like to try a port to ARM eventually, especially to support newer macs,
but this will require a bit more fiddling than just supporting yet
another intel ISA.
What would be required is quite different compiler flags for the
rendering code (so, not -mavx etc) and setting up the dispatcher to send
rendering jobs to the code with the right ISA.
This should not be too hard if Vc supports ARM well, and if it doesn't,
pv can fall back on code which isn't using Vc. The problem is that I
don't have any ARM hardware, so it's hard for me to test. Would you like
to cooperate on an ARM port? I could produce code which should run on
ARM, but lacking testing hardware I'd probably need several attempts
before it comes out right. I'd set up an ARM branch, you can watch it
for new commits, try the build and communicate via the issue tracker.
