Hi all,

I'm relative newbee in QtDeveloppement with c++ on windows.

I' m working on project with integration of videoInput library and Qt4 gui together, but i have some pbm to include this lib in the .pro file for compiling :
I'm using mingw32 and Qt4.43.
this is mi simple .pro file :


Qt Code: 
  1. TEMPLATE = app
  2. TARGET =
  3. DEPENDPATH += .
  4.  
  5. # Input
  6. HEADERS += webcamapp.h
  7. FORMS += winCam.ui
  8. SOURCES += main.cpp webcamapp.cpp
  9.  
  10. INCLUDEPATH += "C:\Program Files\videoInput01995\compiledLib\compiledByDevCpp\include"
  11. LIBS += -L"C:\Program Files\videoInput01995\compiledLib\compiledByDevCpp"
  12.  
  13. LIBS += -videoInputLib.a

i'm testing with -lvideoInputLib to but the lib is not find...!!!

the library is in an directory : videoInputLib.a with an other dir for include .h

If i use this library in codeblocks with the same mingw without Qt4 project there is no pbm....

is there a special command in .pro file to include lib in .a format and not .lib ?
(i can import some other lib if it's in this format from other library).

the make process return this error :
