Hello, my system info: x86_64, Ubuntu 16.04.6, kernel 4.15.0-54-generic, gcc5.4.0, g++5.4.0, autoware-1.11.1.

Installed flycapture2-2.13.3.31-amd64-pkg_xenial, LaydbugSDK_1.16.3.48_amd64 and spinnaker-1.21.0.61-amd64-Ubuntu16.04, then reboot to build autoware. when building with AUTOWARE_COMPILE_WITH_CUDA=1 ./colcon_release, output:

/usr/lib/gcc/x86_64-linux-gnu/5/../../../../lib/libflycapture.so： undefined reference to  ‘powf@GLIBC_2.27’

Failed   <<< autoware_pointgrey_drivers [ Exited with code 2 ]

In Autoware/ros/src/sensing/drivers/camera/packages/pointgrey, the README file doesn't specify the three matched SDK(flycapture, ladybug, spinnaker) version. How to fix this this problem? Did i missing something, thanks for your help!

@jxl There are two problem I can see here:

1. I suspect your system is not Ubuntu 16.04, but 18.04. (glibc version)

The highest glibc version available in Ubuntu 16.04 (as of July 2019) is 2.23, but the linker is stating your version is 2.27, which suspiciously corresponds to the one shipped in Ubuntu 18.04.

You might confirm your glib version executing: ldd --version

and your Ubuntu version executing: lsb_release -a

If you happen to be on Ubuntu 18.04, you'll need to remove previous xenial version, download and install the bionic version of the driver.

2. libladybug.so： undefined reference to ‘FlyCapture2::AVIRecorder::AVIRecorder()’

You cannot install standard FlyCapture SDK (for grashoppers, cameleon cameras, etc) simultaneously with Ladybug's FlyCapture.
