[GnomeMeeting-list] Problems building pwlib 1.10 on Slackware 10.2

[JCA <1 41421 gmail com>]

  I had a go at building Ekiga for Slackware 10.2, and got stumped
when trying to build pwlib 1.10:

mkdir -p ../pwlib/device/videoinput
g++  -DP_USE_PRAGMA -D_REENTRANT -Wall  -fPIC -DPIC
-I/home/ss/Ekiga/pwlib_v1_10_0/include \
vidinput_names.cxx \
-I. -shared vidinput_v4l2.cxx -o ../pwlib/device/videoinput/v4l2_pwplugin.so
In file included from vidinput_v4l2.cxx:127:
vidinput_v4l2.h:150: error: field `videoCapability' has incomplete type
vidinput_v4l2.h:151: error: field `videoStreamParm' has incomplete type

  scope
vidinput_v4l2.cxx:201: error: `V4L2_PIX_FMT_RGB555' was not declared in this
  scope

  Anybody know how to get around this?
