@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

To fix latest compilation issues, add to _cmakeopts:

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

(in addition to the patch provided by @lobomfz)

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:

Compilation fails on grfmt_jpeg2000.cpp with the latest libjaster version. You need to add

sed -i 's/&jas_matrix_get/jas_matrix_getref/g' modules/highgui/src/grfmt_jpeg2000.cpp

to prepare() or apply this patch file i made https://pastebin.com/8cntxG93
