Problem with Qmake
-
Hi,
I need to write some code for an application that uses a camera with an gigabit ethernet connection. The company who made the camera has provided header files to read images from the camera. The files are : ImageLib.h , PvApi.h and PvRegIo.h.
I wrote some code in Snap.cpp and when i compile it this way : @g++-4.4 -Wl,--rpath -Wl,./ -O3 -fno-strict-aliasing -fexceptions -I/usr/include -D_x86 -D_LINUX -Wall -Wno-unused-functionpkg-config --cflags opencv-D_REENTRANT Snap.cpp -o Snap -lpthread -lrt -Bdynamic -lm -lc -lPvAPIpkg-config --libs opencv
@
Everything works.But when i try to put this in an .pro file it won't compile anymore. The reason i want to put this in a .pro file is because the main project has an .pro file so when I succeed in creating a .pro file for this example I can just copy these line into my main project's .pro file to use this code.
My current .pro file for the example i am trying looks like this :
@CONFIG += link_pkgconfig
PKGCONFIG += opencv
PRECOMPILED_HEADER = ImageLib.h
PRECOMPILED_HEADER = PvApi.h
PRECOMPILED_HEADER = PvRegIo.h
SOURCES += Snap.cpp
LIBS += -lrt
LIBS += -Bdynamic
LIBS += -lm
LIBS += -lc
LIBS += -lPvAPI
TARGET = Snap@But when I do "qmake Snap.pro" and then "make" it wont compile.
Can anyone help plz? -
pkg-config —cflags opencv=> this lets me use the opencv library. The first two lines in the .pro file does the same. So that works because I already use it in my main .pro file. The problem is that I can't get the library from the camera working. When i compile with the commandline from the first post it works, but with the .pro file i can't get it to work.The errors i get when using the .pro file are these:

The output of the two commands :
@
-I/usr/local/include/opencv
-L/usr/local/lib -lcxcore -lcv -lhighgui -lcvaux -lml
@My current .pro file:
@CONFIG += link_pkgconfig
PKGCONFIG += opencv
INCLUDEPATH = ./mantalib
SOURCES += Snap.cpp
LIBS += -lrt
LIBS += -Bdynamic
LIBS += -lm
LIBS += -lc
LIBS += -L./mantalib -lPvAPI
TARGET = Snap@The header files i use to use the camera are in the folder mantalib. So i added INCLUDEPATH = ./mantalib to my .pro file. But it isn't working yet:s

I just overlooked this:
@
PvApi.h:105:26: error: #error Define PVDECL to be your compiler keyword for "standard call"
PvApi.h:424:2: error: #error Define specific data types for your platform.
@Looks like you're missing some config defines. Your original stand alone command line contains this define:
@
-D_x86 -D_LINUX
@But that's missing from your .pro file. You could try to add this line to the .pro:
@
DEFINES += _x86 _LINUX
@This should solve the compilation issues.
