[ft-devel] Compilation errors

[Bérenger DALLE-CORT]

Hello,

First, excuse me if my question is a little bit idiot. It can be possible because i'm a beginner in C++ application development.
I try to use FreeType library on a qt project. I have several errors on compilation with the code bellow.
Could you help me ? an advise, an article to read...

Thanks,

Bérenger

The .pro file:

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = AtlasFontMaker2

TEMPLATE = app

SOURCES += main.cpp\

        mainwindow.cpp

HEADERS  += mainwindow.h

FORMS    += mainwindow.ui

INCLUDEPATH +=    ./freeType

The main c++ file:

#include "mainwindow.h"

#include <QApplication>

#include "ft2build.h"

#include <iostream>

#include FT_FREETYPE_H

FT_Library library;

using namespace std;

int main(int argc, char *argv[])

{

    QApplication a(argc, argv);

    MainWindow w;

    w.show();

    FT_Init_FreeType( &library );

    return a.exec();

}
