Qt Creator 10 enabled it back, but it also fixed the issue for disabling it in the first place – the usage of Qt Creator path for the auto-setup.cmake file. Qt Creator 9 made the CMake package manager auto-setup disabled by default. Qt Creator 10 fixes this as seen in the screen cast below: Unfortunately, for projects not using CMake presets, this feature broke the existing workflow of setting environment variables in the build environment and having them available for the CMake configuration step. Qt Creator 9 introduced support for CMake presets which required an environment for the CMake configuration step. Now the CMakePresets.json looks like this: " , This way, I was able to hide the nitty gritty details of the Visual C++ Ninja preset into an msvc.json file. pathListSep field from CMakePresets version 5 is also supported. The “include” field in CMake presets is part of CMakePresets version 4. The compiler automatically adds padding bytes at the end.Now that Qt Creator 10 has been released, it’s time to highlight the CMake changes. Why is that?Īlso, Foo really only has 4+4+1 = 9 bytes of data. So within Bar, I'd expect the Foo member to be at offset 8 (a multiple of 8) while actually it's at offset 4. Int fooOffset = ((int) &bar.foo) - ((int) &bar) // yields 4
Now take the following program: #include
Any member whose size is 8 bytes or more will be at an offset that is a multiple of 8 bytes. Within a struct, I'd think that any member whose size is less than 8 bytes will be at an offset that is a multiple of its own size. Let's assume a pack value of 8 bytes (which is the default).
Multiple of n or a multiple of the size of the member, whichever is The alignment of a member will be on a boundary that is either a However, I seem to have some misconception as to how they work.Īccording to MSDN, for a given alignment value n, Visual C++ offers both a compiler switch ( /Zp) and the pack pragma to affect the aligment of struct members.
