Can you provide some more info on how to build libtiff on my 64 bit machine? I could not find the options in the "configure" step.

The important line would be "ld: warning: in /usr/local/lib/libtiff.dylib, file is not of required architecture" You have a libtiff that isn't compiled for your architecture.
(probably 32 bit when you need 64, or vice versa)

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.
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";
std::cout << "hello";
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
"_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?
