Daily branch Linux path to QT5

[aurquiel]

I have notice the include for star projects of QT5 in the daily branch development, but i don't know it's already ready.

I have installed QT creator 5.8 and my QT folder is at /opt/QT

In the location of QT5 i introduced /opt/Qt/5.8/Src/qtbase but the wizard returned the error

Code

The path you entered seems valid, but this wizard
can't locate the following Qt's library file:
Qt5Core in it.
(Also tried prepending lib and appending .a and .lib).

Maybe is too early to use this wizard tool for QT5 or ia m doing something wrong.

Probably the wizard is just broken for this version.
You can right click on the wizard's icon and choose edit script.
Then you can inspect what is trying to do and why it is failing.

Qt project have done some file restructuring between 4 and 5 and probably the wizard is not fully aware of them.

The problem was i choose the wrong file path

The correct one is

Code

/opt/Qt/5.8/gcc_64

Then the wizard create the main file as follow

Code

#include <QApplication>
#include <QFont>
#include <QPushButton>

int main(int argc, char* argv[])
{
    QApplication app(argc, argv);

    QPushButton quit("Quit");

    quit.resize(75, 30);
    quit.setFont(QFont("Times", 18, QFont::Bold));

    QObject::connect(&quit, SIGNAL(clicked()), &app, SLOT(quit()));

    quit.show();

    return app.exec();
}

But when i compile give the error

Code

||=== Build: Debug in ee (compiler: GNU GCC Compiler) ===|
/opt/Qt/5.8/gcc_64/include/QtCore/qglobal.h|1097|error: #error "You must build your code with position independent code if Qt was built with -reduce-relocations. " "Compile your code with -fPIC (-fPIE is not enough)."|

Did you try adding the suggested option?

Project -> Build Options...
Tab Compiler Settings
In either tab "Compiler Flags" or "Other Compiler Options"

I did, but a bunch warnings shows up

Please read this site rules http://forums.codeblocks.org/index.php/topic,9996.0.html

Then, find a programming site like https://cboard.cprogramming.com/forum.php
To ask programming questions on and also learn programming on sites like that.

This site does NOT teach programming.

FYI: Those are linker errors you posted.

And, thank you for using code tags in your post.

The programming site will likely need a build log output to help you.

Edit: The link says how to get a full/complete build log; many newbies do NOT know this.
