Boost 1.47 link with QtCreator2.5

qinsisi

Hi, I have searched all the posts about Boost but still cannot fix my problem...
I just want to use Boost library only, but suffering on it.

My Steps:

Install boost : sudo port boost.
it installed header files and library files into /opt/local/include and /opt/local/lib
create a C++ project in QtCreator2.5
testing code
@
#include <iostream>
#include <boost/asio.hpp>

int main ()
{
return 0;
}
@
pro file is
@
TEMPLATE = app
CONFIG += console
CONFIG -= qt

INCLUDEPATH += /opt/local/include #I add this
LIBS += -L/opt/local/lib #I add this

SOURCES += main.cpp
@

And then I built, the result is
@
make: Entering directory /Users/qinsisi/test/timer' g++ -headerpad_max_install_names -arch i386 -arch x86_64 -Xarch_x86_64 -mmacosx-version-min=10.5 -o 01_timer.app/Contents/MacOS/01_timer main.o -L/opt/local/lib ld: warning: ignoring file main.o, file was built for unsupported file format which is not the architecture being linked (i386) Undefined symbols for architecture i386: "_main", referenced from: __start in crt1.o ld: symbol(s) not found for architecture i386 collect2: ld returned 1 exit status Undefined symbols for architecture x86_64: "boost::system::system_category()", referenced from: __static_initialization_and_destruction_0(int, int)in main.o boost::asio::error::get_system_category() in main.o "boost::system::generic_category()", referenced from: __static_initialization_and_destruction_0(int, int)in main.o "boost::asio::error::get_netdb_category()", referenced from: __static_initialization_and_destruction_0(int, int)in main.o "boost::asio::error::get_addrinfo_category()", referenced from: __static_initialization_and_destruction_0(int, int)in main.o "boost::asio::error::get_misc_category()", referenced from: __static_initialization_and_destruction_0(int, int)in main.o ld: symbol(s) not found for architecture x86_64 collect2: ld returned 1 exit status lipo: can't open input file: /var/folders/20/20d5ly4n7qv3d61_30dd5x180000gn/T//ccfhHDpX.out (No such file or directory) make: *** [01_timer.app/Contents/MacOS/01_timer] Error 1 make: Leaving directory /Users/qinsisi/test/timer'

I have tried to do this,
macx:CONFIG -= x86
macx:CONFIG -= x86_64
but failed.

i also tried to right click on project and go to "Add Library"
I tried "external Library" and "system library", but I cannot see /opt/local/ folder so that i cannot select the directories.

Anyway, thanks in advance.
