Qt 6.3.1 looking for header files ??

britsfp

I do not know if this is in another forum, I do not have the patience or time to search for it, so here is my troubles ::

Wow Im waiting now for a year or more for Qt to get their act together. I tried Qt 6.3.1 today and guess what ? ...... still problems::
1) qfile.h includes a thing called "filesystem" of course there is no such a file as "filesystem"

2) In QtGui there is a call to include a file called : GL/gl.h and ... you guessed it .... there is no such a file as gl.h

So I will install again in a year's time and see if they get things right then :-(((((((

filesystem is a C++ header : https://en.cppreference.com/w/cpp/header/filesystem . If you don't have it, you don't have a working C++17 toolchain.

In QtGui there is a call to include a file called : GL/gl.h and ... you guessed it .... there is no such a file as gl.h

GL/gl.h is a libgl header . I assume you're on LInux? Then you need to find the system package that installs it...

So I will install again in a year's time and see if they get things right then :-(((((((

These dependencies are unlikely to change. So waiting won't help.

Do: apt-get install libmesa-dev
Regarding "filesystem": my Ubuntu 20.04 has it. What Linux distribution do you have?
They already have the things right, you just need to install needed dependencies as always on Linux. See https://doc.qt.io/qt-6/linux.html
