"Use of undeclared indentifier" error messages
-
I recently installed, using the online installer, the latest version of Qt/QtCreator (5.12.0, 4.8.0-rc1) on a clean install of Ubuntu 18.04 Everything seems to be working fine when recompiling and running my programs., except for the tons of error messages I get. See screenshot below for the simplest console application. My only additions to the cpp file generated by QtCreator are including iostream, and adding the std::cout line (which generates the message "expected expression). The program runs fine: it opens a console and prints "hello world" as instructed.
In my other programs i get messages like "variable has incomplete type 'void' ", "expected identifier or '(' " and numerous others, but in all cases I've looked so far they do what I expect them to.
The program was compiled with: CONFIG += c++11 console. Turning off Clang Code Model (under "Issues") did not change anything.
Thanks for your help, Gert

Hi and welcome to devnet forum
You are using a release candidate of Qt creator. In the mean time we have 4.8.1 offically out. I recommend changing to the offical version. That might remove the problem already. Release candidates are still not the final version and may show unwanted behaviour.

This did not switch off the Clang Code Model. It is a plugin and you need to unselect under "Help"->"About Plugins..." under "C++" "ClangCodeModel" and probably restart creator.

Thank you, that helped. When installing I just took the top option for QtCreator. I did look for updates using the maintenance tool, but it did not show any. It still does not, maybe 4.8.1 does not count as an update. Anyway for the moment I am happy again.

@Gert-van-der-Zwan Well, an RC is newer than current stable version. Simply remove the RC version of QtCreator in Maintenance Tool and then select "Qt/Tools/QtCreator" there,
