Hello team,
openvdb is updated to 7.1.0 in Rawhide and luxcorerender needs to switch
to -std=c++14 similar to that upstream ticket:
https://github.com/AcademySoftwareFoundation/openvdb/issues/795.
Is there anyone knowing how to do it on the spec file?
https://src.fedoraproject.org/rpms/luxcorerender/
It seems "sed -i 's|${CMAKE_CXX_FLAGS} -std=c++11|${CMAKE_CXX_FLAGS}
-std=c++14|' CMakeLists.txt" is not enough because "-std=c++11" still
comes back.
Looks like it's specified here:
cmake/PlatformSpecific.cmake
I would just patch it instead.
I would also suggest patching the main CMakeLists file, for instance the following way:set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
If that's not too invasive, of course.
Thanks for quick response. The suggestion seems to work. Unfortunately, the build failed on openvdb (either using the bundled and 7.1.0 version) while working fine on Fedora 32.
The build.log logfile isn't informative at all :(. I would try checking all of the flags the %cmake macro adds to the regular cmake call and try to build the thing outside of mock, locally.
Also, maybe set the compiler to clang to get better output:
CXX=clang++
CC=clang
Clang, at least in my experience, tends to be a lot more pedantic and verbose. However, it may behave differently and fail the build in other ways.
