Since years I'm not maintaining anything of the list below other
than some updates when I needed them for some reason. Other people
is doing that maintenance on my behalf so I better take me out but
for very few packages. Finally!
On aarch64 ipp is not available but the derivation still tries to download it
leading to an error that the platform is not supported.
There is already an option to enable ipp which is disabled by default.
So the sensitive thing to do is to only download the ippicv package if
the option is enabled.
This makes opencv3 build on aarch64.
Uses the HTTPS url for cases where the existing URL has a permanent
redirect. For each domain, at least one fixed derivation URL was
downloaded to test the domain is properly serving downloads.
Also fixes jbake source URL, which was broken.
OpenCV's CMakeFile will use libraries in /lib and /lib64 if it can
find libraries from those paths. However, it causes
build failure because nix detects impure paths being used.
If ippicv can't be found in the directory:
3rdparty/ippicv/downloads/${platform}-${md5}
it will be downloaded instead. Commit 7fedbe7 accidentally swapped the
md5 with the sha256 causing ippicv to be downloaded each time opencv
gets build. This patch fixes that.
Patch is from https://github.com/opencv/opencv/pull/6009. Upstream doesn't
seem particularly enthusiastic about a 3.1.x point release, so who knows
when this fix would otherwise see the light of day.
