Integrating Qt and Pylon (Basler camera software)

Same error with all back slahses replaced as forward slashes - https://ibb.co/LR8Ft7p.

I got the lib folder from this OpenCV download link: https://uptobox.com/3ep5xbddl9nn - this worked on the MinGW.

I also tried the libraries from this OpenCV download (seems to be the more standard download): https://sourceforge.net/projects/opencvlibrary/

I am now getting this error: https://ibb.co/MhzLz8p

These are the Basler libs: https://ibb.co/t22TtPp
I tried using both the Win32 and x64 versions in QT.

Not sure what I am missing :/

@colinodowd

Please post your .pro file as text. The LIBS lines are incorrect.

The syntax is: LIBS += -L/path/to/library -llibrary1 -llibrary2 ...

Edit: Seems you changed that in the meantime, because it was already better in earlier posts...

@aha_1980 any thoughts on this?

Hi @colinodowd,

your file got a bit messed up here. I'll post the relevant part edited like it should work:

INCLUDEPATH += "C:/Program Files/Basler/pylon 5/Development/include"
LIBS += -L"C:/Program Files/Basler/pylon 5/Development/lib/Win32" \
        -lGCBase_MD_VC141_v3_1_Basler_pylon.lib \
        -lGenApi_MD_VC141_v3_1_Basler_pylon.lib \
        -lPylonBase_v5_2.lib \
        -lPylonC.lib \
        -lPylonGUI_v5_2.lib \
        -lPylonUtility_v5_2.lib

INCLUDEPATH += C:/Users/colin.odowd/Downloads/opencv/build/include
LIBS += -LC:/Users/colin.odowd/Downloads/OpenCV-2.4.9/build-qt/lib \
        -lopencv_calib3d249d \
        -lopencv_contrib249d \
        -lopencv_core249d \
        -lopencv_features2d249d \
        -lopencv_flann249d \
        -lopencv_gpu249d \
        -lopencv_highgui249d \
        -lopencv_imgproc249d \
        -lopencv_legacy249d \
        -lopencv_ml249d \
        -lopencv_nonfree249d \
        -lopencv_objdetect249d \
        -lopencv_ocl249d \
        -lopencv_photo249d \
        -lopencv_stitching249d \
        -lopencv_superres249d \
        -lopencv_ts249d \
        -lopencv_video249d \
        -lopencv_videostab249d

It seems, the opencv libs are debug versions, which is marked by the trailing d, like "opencv_ts249d". It may therefore be, that you cannot use them with a release build program.

Do you have libraries without trailing d?

@aha_1980

That folder only had libs with 'd' at the end.
Where I downloaded from: https://uptobox.com/3ep5xbddl9nn - this worked on the MinGW.
Ran your refined INCLUDE and LIB in both release and debug mode and got this error message:
https://ibb.co/YQ3FY5p

Where I downloaded from: https://sourceforge.net/projects/opencvlibrary/
I then tried using a differnet OpenCV folder with a library that did not have a 'd' at the end and got this error message:
https://ibb.co/gZGrwTQ

Does anyone know what I am doing incorrectly?

aha_1980

@colinodowd one backslash got lost in my snippet, I added it.

And once again: on Windows all libraries have to fit your compiler. You cannot use MSVC libs with MinGW or vice versa. So make sure OpenCV is compatible to what you're using.

@colinodowd
why do you have quotation marks around your path's? I'm not sure those are interpreted correctly

aha_1980

@j-hilk said in Integrating Qt and Pylon (Basler camera software):

why do you have quotation marks around your path's? I'm not sure those are interpreted correctly

Because when you have spaces in the path, then you have to add the quotes. Otherwise it will fail to parse the path...

@aha_1980
oh, I totally missed that! I try to avoid special chars - that includes spaces - in all paths when possible.
