Please fix libpmemobj-cpp at your earliest convenience and set the bug's status to
ASSIGNED when you start fixing it. If the bug remains in NEW state for 8 weeks,
libpmemobj-cpp will be orphaned. Before branching of Fedora 35,
libpmemobj-cpp will be retired, if it still fails to build.

Comment 4 Luke 2021-02-03 16:23:22 UTC 
It seems like this is gcc 11 issue.

I've used latest rawhide docker to play with this issue and it seems like a test within CMake should not succeed on Unix/Linux system (see attached CMake test, a snippet from our build - from CMakeFiles/CMakeOutput.log ).

I've tried different cmake (3.18.3), I've checked on Fedora 33 & 32 (with previous gcc versions) and I used clang build. They all produce:
```
-- Performing Test CXX_HAS_/Zc:__cplusplus - Failed
```

cmake success /Zc:cplusplus flag
Comment 6 Luke 2021-02-05 10:53:42 UTC 
We've included a fix in our CMake to skip this check (on Linux) in our recent version (1.12-rc1: https://github.com/pmem/libpmemobj-cpp/tree/1.12-rc1).

Anyway I still believe this issue should be followed in gcc component.

This bug appears to have been reported against 'rawhide' during the Fedora 34 development cycle.
Changing version to 34.
Comment 8 Adam Borowski 2021-02-15 15:26:23 UTC 
Fixed version uploaded to rawhide and f34.
