Dear folks,
I have problems using qmake to compile my simplest libtiff program. Here are
the information about my system.
*computer:* Darwin Darwin Kernel Version 10.2.0: Tue Nov 3 10:37:10 PST
2009; root:xnu-1486.2.11~1/RELEASE_I386 i386
*Qt version*: Qt 4.6.2
*libtiff version*: 3.9.2
*operating system*: snow leopard.
Simplest program:
*#include <QtCore/QCoreApplication>*
*#include "tiff.h"*
*#include "tiffio.h"*
*#include <iostream>*
*
*
*int main(int argc, char *argv[])*
*{*
* //QCoreApplication a(argc, argv);*
* TIFF* tif = TIFFOpen("foo.tif", "r");*
* if(tif == NULL)*
* std::cout << "could not open the file";*
* TIFFClose(tif);*
* //return a.exec();*
* **std::cout << "hello";*
* return 0;*
*}*
my pro file:
QT -= gui
TARGET = libtiffSimpleTest
CONFIG += console
CONFIG -= app_bundle
TEMPLATE = app
LIBS += -ltiff
SOURCES += main.cpp
I used Qt creator as my IDE. When I run compiling program I got the
following error:
ld: warning: in /usr/local/lib/libtiff.dylib, file is not of required
architecture
Undefined symbols:
"_TIFFOpen", referenced from:
_main in main.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
make: *** [libtiffSimpleTest] Error 1
However, when I just use the following:
*g++ main.cpp -ltiff*
It works well. What is the problem here?
Thank you.
Dave
