I am using -isystem /mingw64/include/qt6/QtCore so why does it say file does not exist?

Instead of manually adding include directory, use pkgconfig or cmake or related things.

#

oh no I am debugging

#

project uses make

#

so I am trying to figure out why it doesn't work

#

i am reproducing the error manually

#

oh

#

..

#

I got it

spare sandal
#

How did you fix it?

bold ember
#

instead of importing
/mingw64/include/qt6/QtCore
I import
/mingw64/include/qt6

#

what I don't get is how it the mantainers compiled it before...

spare sandal
#

What is "Import" here? Can you provide the proejct link?

bold ember
#

it's actually a cool app

#

it uses mingw to compile on windows

#

The #includeseems wrong here. It should be just #include <QObject>
Though projects are free to do anything.

#

Also, the include directory from pkgconfig output has QtCore.

$ pkgconf -cflags Qt5Core
-DQT_CORE_LIB -IF:/msys64/ucrt64/include/QtCore

oh

#

maybe it's a bug

The repository seems popular, so it's not a bug - a feature 🥲

How could I debug this? does this have to do with mingw path conversion?

spare sandal
#

export PATH=$PATH:/mingw64/bin Why? It's already in PATH.

bold ember
#

maybe at the end it did something? idk

#

just throwing stuff at the wall to see what sticks

spare sandal
#

The easiest way I found to use MSYS=winjitdebug environment value. Close any msys2 instance > Set that environment value > start msys2/mingw terminal > start program > there will be a window with the dll missing.
