LibUSB linking problem #9

Closed joanpepcompany closed 8 years ago

joanpepcompany commented 8 years ago

I'm trying to compile the code, but I'm having the following error: /usr/lib/gcc/x86_64-linux-gnu/4.8/../../../../lib/libflycapture.so: undefined reference to libusb_handle_events_timeout_completed' /usr/lib/gcc/x86_64-linux-gnu/4.8/../../../../lib/libflycapture.so: undefined reference tolibusb_hascapability' It seems a linking problem with the library. LibUSB library is installed. Do you know any solutions for this issue? Thanks in advance.

Are you using the latest 2.9.3 flycapture sdk? Can you try linking to libusb explicitly in the CMakeLists? Just add usb-1.0 to line 44 and see if it works?

target_link_libraries(
    ${PROJECT_NAME}
    ${catkin_LIBRARIES}
    ${FlyCapture2_LIBRARIES}
    usb-1.0
    )

Also, try running flycap and see if it can successfully recognize and open your camera.

SOLVED, I've just add usb-1.0 at CMakelists as you propose. Thanks.
