Help linking LibTiff

[rdelgado]

Hello All,

I need to read some TIFF using the libtiff in Windows.
I have just build the libtiff and I have my .lib files correctly in a folder.
Then I used the QtCreator Add Library function to add the library to my project and this is the result:

#-------------------------------------------------
#
# Project created by QtCreator 2014-09-02T10:15:41
#
#-------------------------------------------------
 
QT       += core
 
QT       -= gui
 
TARGET = PruebaLibTiff
CONFIG   += console
CONFIG   -= app_bundle
 
TEMPLATE = app
 
 
SOURCES += main.cpp
 
 
win32:CONFIG(release, debug|release): LIBS += -L$$PWD/libtiff/.libs/ -ltiff
#else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/libtiff/.libs/ -ltiffd
#else:unix: LIBS += -L$$PWD/libtiff/.libs/ -ltiff
 
INCLUDEPATH += $$PWD/libtiff/.libs
DEPENDPATH += $$PWD/libtiff/.libs
 
win32:CONFIG(release, debug|release): LIBS += -L$$PWD/libtiff/.libs/ -ltiffxx
#else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/libtiff/.libs/ -ltiffxxd
#else:unix: LIBS += -L$$PWD/libtiff/.libs/ -ltiffxx
 
INCLUDEPATH += $$PWD/libtiff/.libs
DEPENDPATH += $$PWD/libtiff/.libs

I have commented the debug and unix versions of the includes.

Then, this is my main file:

#include <QCoreApplication>
#include <QDebug>
#include <inttypes.h>
#include "C:/Qt/Programas/PruebaLibTiff/libtiff/tiffio.h"
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
 
    TIFF *tif;
    tif = TIFFOpen("MARBLES.TIF", "r");
 
    return a.exec();
}

#include <QCoreApplication>
#include <QDebug>
#include <inttypes.h>
#include "C:/Qt/Programas/PruebaLibTiff/libtiff/tiffio.h"

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    TIFF *tif;
    tif = TIFFOpen("MARBLES.TIF", "r");

    return a.exec();
}

To copy to clipboard, switch view to plain text mode 

But when I compile and run, I keep getting the "undefined reference to TIFFOpen" error.

Could you help me? What am I doing wrong.

If I use the Ctrl-Space command in Qt, I can see all the TIFF functions, including TIFFOpen. Why cant I compile then?

Thanks!

Just a side note -- you are aware Qt can open TIFF files using one of its plugins, right?
