Bug ID: 405212
Summary: Compilation error because of QOverload usage
Product: krusader
Version: 2.7.1
Platform: Other
OS: All
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: ---
SUMMARY
There are few usages of QOverload in current code base.
QOverload was introduced in QT 5.7. Krusader compilation check QT version >
5.5. So if I have QT vesion < 5.7 compilation fails:
/krslots.h:48:23: error: ‘QOverload’ was not declared in this scope
STEPS TO REPRODUCE
1. Have QT version 5.6.1
2. Run cmake
3. Run make
OBSERVED RESULT
Compilation crashes with: /krslots.h:48:23: error: ‘QOverload’ was not declared
in this scope
EXPECTED RESULT
Successful compilation
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Ubuntu 16
(available in About System)
Qt Version: 5.6.1
ADDITIONAL INFORMATION
I can fix it, but there are more possibilities:
1. Replace QOverload with static_cast
2. Raise minimal QT version to 5.7
3. Selective compilation #if QT_VERSION <= QT_VERSION_CHECK(5, 7, 0)
More ideal?
