Hi all,
I've wasted many time to search how I should configure my Qt Creator to link OpenAL in my application so I try with posting my problem right here.

Well my problem is very simple:
I have Qt Creator 2.0.1 with Qt 4.7 and Windows 7 x64 and haven't got any problem before trying to link OpenAL.
I saw that I have to add my library to "LIBS" in my .pro file. So here is my .pro:
Qt Code: 
  1. QT       += core gui
  2. TARGET = OpenALTest
  3. TEMPLATE = app
  4. SOURCES += main.cpp\
  5.         mainwindow.cpp
  6. HEADERS  += mainwindow.h\
  7.             sndfile.h
  8. FORMS    += mainwindow.ui
  9. INCLUDEPATH += C:/OpenALSDK/include
  10. LIBS    += -LC:/Qt/2010.05/qt/OpenALTest/ -lsndfile-1 \
  11.            -LC:/OpenALSDK/libs/ -lopenal32
To copy to clipboard, switch view to plain text mode 

I downloaded OpenAL SDK which is composed (especially) of .h file that I include and an OpenAL32.lib file which I mention in my "LIBS" configuration variable.

The result I have is:
C:\Qt\2010.05\qt\OpenALTest-build-desktop/../OpenALTest/mainwindow.cpp:31: undefined reference to `_imp__alcOpenDevice'
C:\Qt\2010.05\qt\OpenALTest-build-desktop/../OpenALTest/mainwindow.cpp:39: undefined reference to `_imp__alcCreateContext'
C:\Qt\2010.05\qt\OpenALTest-build-desktop/../OpenALTest/mainwindow.cpp:47: undefined reference to `_imp__alcMakeContextCurrent'
...

I believe that my code won't help you because it's just a link problem but ask me if necessary.
I also tried with this:
Qt Code: 
  1. LIBS    += -LC:/Qt/2010.05/qt/OpenALTest/ -lsndfile-1 \
  2.            -LC:/OpenALSDK/libs/OpenAL32.lib
To copy to clipboard, switch view to plain text mode 
and

Qt Code: 
  1. LIBS    += -LC:/Qt/2010.05/qt/OpenALTest/ -lsndfile-1 \
  2.            C:/OpenALSDK/libs/OpenAL32.lib
To copy to clipboard, switch view to plain text mode 

May someone help me?

Thx
