@A123 said in New Errors when moving C++ code to QT Creator: its been used by others for years and it worked perfectly AFAIK with gcc and clang before I started using qtcreator which complained. Here's my guess: Previously, the assert() macro was disabled. This caused the illegal code to be effectively "commented out", so the compiler didn't detect it. After the migration, the assert() macro was no longer disabled, so the compiler now sees the bad code and (correctly) complains. See http://www.cplusplus.com/reference/cassert/assert/. You could make your code work again by defining the NDEBUG macro, but be careful: This will disable all assert()s which might cause other errors to go undetected. P.S. The compiler is the one that complained, not Qt Creator.

@BINALECTRUM said in Android build and deploy. 64bit, Clang, new app store developer console rules [2018 & 2019]: Is Qt going more in embedded/car side and just slowly drops Android/mobile platform? In Roadmap 2018 there is nothing new about mobile platform. i heavily doubt that. I guess the reason is more because Qt runs more or less stable on Android. There are no bigger features which need to be implemented, mostly bug fixing. What is your move Qt team on new app store rules in developer console: minimal platform-26 in August 2018 and 64-bit apk in 2019? Some new changes in build and deploy area? i asked this at the beginning of the year, but unfortunately haven't received an answer.

Did you install Xcode 8 ? Your other error comes from the fact that you are calling xcodebuild in the folder where it's located and not where a Xcode project can be found.

@SGaist Thank you.

Yes, I'm newbie in C++ and didn't know the problem with different libraries and compilers. Now it is clear. Thank you very much!

@SGaist Thanks! I'll waiting for next release!

ok finally: modifying Qt/5.3/clang_64/mkspecs/macx-clang/qmake.conf this way: #QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.6 QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.7 did the job. just in case anybody needs this again. seems easy afterwards -.-

Hi and welcome to devnet, You should bring this topic on the Qt Creator maling list You'll find there Qt Creator's developers/maintainers (this forum is more user oriented)
