[QtCreator] Clang code model & <cstdint>

[phlf]

Hello,

I'm using Qtcreator 4.4 and I have this strange issue in one of my project where the Clang code model keeps throwing at me:

But the #include <cstdint> is present in my code, so I don't really get what's happening there.
Here is part of my Qmake file:

TEMPLATE = app
CONFIG += console
CONFIG -= app_bundle
CONFIG -= qt

QMAKE_CXXFLAGS += -std=c++1z
QMAKE_CXXFLAGS_RELEASE += -O3

[...]

LIBS += -lSDL2 -lpthread

I also tried with:

TEMPLATE = app
CONFIG += console
CONFIG += c++11
CONFIG -= app_bundle
CONFIG -= qt

[...]

QMAKE_CXXFLAGS_RELEASE += -O3

LIBS += -lSDL2 -lpthread

I looked for a solution over the internet, but the best answer I found was "misconfigured kit". which is not really explicit.

Thanks to anyone able to give some hints about this.
