I am following the directions for installation of all the libraries, etc., for using Kinect with Greenfoot, on my Mac, version 10.7.4. I have the Kinect working, so I'm at the point of installing the kinectserver-1.2. I do this, as the instructions say: ./configure --with-boost=/opt/local/include --with-wx-config=/opt/local/bin/wx-config --with-wx-prefix=/opt/local and it gets quite a ways through, but then dies with configure: error: cannot find the flags to link with Boost thread Searching through config.log for BOOST, I find this: BOOST_CPPFLAGS='-I/opt/local/include' BOOST_LDPATH='/opt/local/lib' BOOST_PROGRAM_OPTIONS_LDFLAGS='-L/opt/local/lib ' BOOST_PROGRAM_OPTIONS_LDPATH='/opt/local/lib' BOOST_PROGRAM_OPTIONS_LIBS='/opt/local/lib/libboost_program_options-mt.a' BOOST_ROOT='' BOOST_SYSTEM_LDFLAGS='-L/opt/local/lib ' BOOST_SYSTEM_LDPATH='/opt/local/lib' BOOST_SYSTEM_LIBS='-lboost_system-mt' BOOST_THREAD_LDFLAGS='' BOOST_THREAD_LDPATH='' BOOST_THREAD_LIBS='' and #define HAVE_BOOST 1 #define HAVE_BOOST_SYSTEM_ERROR_CODE_HPP 1 #define HAVE_BOOST_ASIO_HPP 1 #define HAVE_BOOST_SCOPED_PTR_HPP 1 #define HAVE_BOOST_SHARED_PTR_HPP 1 #define HAVE_BOOST_PROGRAM_OPTIONS_HPP 1 #define HAVE_BOOST_SYSTEM_ERROR_CODE_HPP 1 #define HAVE_BOOST_THREAD_HPP 1 which all seems pretty good to me. Can someone help? Thanks. Vic
