* fix compilation on Qt not having QOperatingSystemVersion::MacOSBigSur
The code uses 'QOperatingSystemVersion::MacOSBigSur' which doesn't exist
in all Qt versions (it has been backported to Qt 5.12.10+ & 5.15.1+ only).
On older macos systems like El Capitan the last supported
version of Qt is 5.11
This will fix compilation issue on such older systems and on systems
running with Qt not supporting QOperatingSystemVersion::MacOSBigSur
Compilation error was:
error: no member named 'MacOSBigSur' in 'QOperatingSystemVersion'
* Fix compilation when osx <= 10.9
* AppKitImpl.mm: button property is new in 10.10. It is used for a feature of
KeePassXC that is only available from 10.17 onwards. So we don't need it when
compiling on <= 10.9
error: property 'button' not found on object of type 'NSStatusItem *'
NSString* appearance = [dummy.button.effectiveAppearance.name lowercaseString];
^
* The code uses @available syntax which is supported by
AppleClang >= 9 or LLVM >= 5.
We check __clang_major__ to allow compilation on older versions
of macOS that don't have a recent clang. For example on El Capitan.
* Fix compilation when osx <= 10.8
* AppKitImpl.mm: AXIsProcessTrustedWithOptions exists from 10.9 onwards
error: use of undeclared identifier 'kAXTrustedCheckOptionPrompt'
error: use of undeclared identifier 'AXIsProcessTrustedWithOptions'
* Fix compilation when osx <= 10.7
* MacUtils.cpp: CoreGraphics exists from 10.8 onwards only, capslock detection
feature would have to be implemented on OSX <= 10.7
* AppKitImpl.mm: CGDisplayStreamRef exists from 10.8 onwards only. It is used for a
feature of KeePassXC that is only available from 10.15 onwards. So we don't need it
when compiling on <= 10.7
error: unknown type name 'CGDisplayStreamRef'
* AppKitImpl.mm: Syntax is not understood by 10.7, update it to be understandable
by <= 10.7
error: expected method to read dictionary element not found on object of type 'NSDictionary *'
NSRunningApplication* app = userInfo[NSWorkspaceApplicationKey];
^
* The code uses @available syntax which is supported by
AppleClang >= 9 or LLVM >= 5.
We check __clang_major__ to allow compilation on older versions
of macOS that don't have a recent clang.
* Fix compilation error on OS X 10.11
src/core/Alloc.cpp:44:10: error: no type named 'free' in namespace 'std'
std::free(ptr);
~~~~~^
This is a regression, since it was fixed in [1]
Per [2], std::free() needs #include <cstdlib>. That file is included
indirectly on newer systems.
[1] 7c6c027d33
[2] https://en.cppreference.com/w/cpp/memory/c/free
* fix compilation when macos SDK <= 10.14
These methods are only available from macOS 10.15
- kSecAccessControlWatch
- LAPolicy.deviceOwnerAuthenticationWithBiometricsOrWatch
The code uses @available syntax which is supported by
AppleClang >= 9 or LLVM >= 5.
We check __clang_major__ to allow compilation on older versions
of macOS that don't have a recent clang.
