stddef.h not found in QtCreater

msauer75

Hi,
I create a console project without Qt. QtCreator creates a lot of messages like

stddef.h not found
stdard.h not found
use of undeclared identifiert 'NULL'

and so on.

But the project can compile without any errors.
Can you tell me where the problem is?

Thank you for your help.

@msauer75 This is probably caused by the Clang code model. You can disable Clang code model plug-in in "Help/Plugins...".

@msauer75 said in stddef.h not found in QtCreater:

But the project can compile without any errors.

What do you mean by this, if you are saying it does not compile in Qt Creator. Or maybe you're saying the opposite way round? It may be just me, but I am not understanding which environemnt you say does work and which does not?

At any rate, whether from inside Qt Creator or outside, you need to make sure your include path is correct. It looks like it is not finding those header files in the system directories where it should, so either it is looking in the wrong place or they are not where they should be.

Thank you. Now it works.

@jsulm Thank you.
And for qtcreator 4.11.0, it should be "Help -> About Plugins -> C++ -> ClangCodeModel".
