I uninstalled jasper and opencv2 built properly. Thanks for the tip!

@nedludd: I've jasper:2.0 installed, it's incompatible with opencv2 but gets dragged into by cmake and introduce the issue. ~I can't see immediate solution, you can build opencv2 in clean chroot with extra-x86_64-build provided with devtools package, or uninstall jasper for a moment to build opencv2.~

[Edit] Fixed: malformed cmake flags 5feaf8edb556, force build jasper locally 00d6b2f8ccb2

@nedludd: Can't reproduce, file is located in modules/highgui/src/grfmt_jpeg2000.cpp looks fine and builds without only some rudimental warnings from tbb header (could you please post your build.log, preferably with tool like https://aur.archlinux.org/packages/ix or site like https://paste.c-net.org/ )

The compilation failure on grfmt_jpeg2000.cpp is still there. Can you fix @bartus?

bartus commented on 2021-07-06 10:07 (UTC)

Fixed.

I managed to build, but not install:

error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: opencv2 and opencv2-samples are in conflict

pantos commented on 2021-05-22 20:02 (UTC)

To fix latest compilation issues, add to _cmakeopts:

'-D CMAKE_CXX_FLAGS="-std=gnu++11"'

(in addition to the patch provided by @lobomfz)

boennhoff commented on 2021-04-26 07:53 (UTC) (edited on 2021-04-26 07:54 (UTC) by boennhoff)

Compilation is broken since many month (years?), see @lobomfz. Please abandon the package @ashok if there is no time to take care.

The following extra patch is necessary to allow building the highgui module:
