Hi all,

A few days ago i found this program. It is really very impressive.
I made all the instructions but i have the same error like Chris had.

Here is the error:

If someone knows how to solve this problem, please answer me.

Thank you,

This problem is because the vxl headers have not been installed. After building vxl with the 'make' command type
sudo make install
this should be done from the $VXLBIN directory

That is how it's supposed to work however I find that the install process fails part way through with this error
------------------------------------------------------------------------------------------
CMake Error at core/testlib/cmake_install.cmake:53 (FILE):
  file INSTALL cannot find file
  "/home/markt/Track-I/Open-Gazer/bin/lib/libtestlib.so" to install.
Call Stack (most recent call first):
  core/cmake_install.cmake:49 (INCLUDE)
  cmake_install.cmake:40 (INCLUDE)
------------------------------------------------------------------------------------------

I haven't found a fix for this yet but here's a work around. All the header files are present in the vxl source tree so you can hack your opengazer Makefile to search here for include file. In your opengazer directory
gedit Makefile

here's what I did...

------------------------------------------------------------------------------------------
# required libraries: vxl, opencv, boost, gtkmm

VXLDIR = /home/markt/Track-I/Open-Gazer/bin
VXL2DIR= /home/markt/Track-I/Open-Gazer/vxl-1.14.0
VERSION = opengazer-0.1.2
CPPFLAGS = -Wall -g -O3
LINKER = -L$(VXLDIR)/lib -L/usr/local/lib -lm -ldl -lvnl -lmvl -lvnl_algo -lvgl -lgthread-2.0

# change the following line if your vxl library is installed elsewhere
INCLUDES = $(foreach prefix, /usr/local/include $(VXLDIR) $(VXL2DIR), \
        $(foreach suffix,/core /vcl /contrib/oxl,-I$(prefix)$(suffix)))
------------------------------------------------------------------------------------------

That will fix the missing include files error.
The next error you will come across is this
------------------------------------------------------------------------------------------
    PointTracker.h:11: error: reference to ‘exception’ is ambiguous

    /usr/include/boost/exception/exception.hpp:177: error: candidates are: class boost::exception

    /usr/include/c++/4.4/exception:60: error: class std::exception
------------------------------------------------------------------------------------------

To fix this check this page

http://d.hatena.ne.jp/kazekyo/20100505/1273062727

It's mostly in chinese but the command lines are in english so you kind of get the gist.
I found that following this I could get opengazer to build.
Now I'm going to buy a web cam!
Good luck everyone!
