Hi,

I'm trying to install cvEyeTracker but I'm getting some strange problems. I was in general help before but after being very informative Segfault concluded something mysterious is going on and suggested that I go to the people who know everything.

"I'm not a programmer, IMO this means the program you are trying to compile has syntax errors, possible is the syntax is changed and the way they wrote it back in 2006 is obsolete now.
Try posting here at Linuxforums Progamming subforum."

Here's my error, pulled from the console:

eyetracker@eyetracker-desktop:~/Documents/cvEyeTracker-1.2.5$ make

Thanks very much

Does anyone know a resolution to this problem? I'm really hoping to get cveyetracker installed and I'm nearing the end of my luck...

Step one: check the installation instructions (I imagine it came with installation instructions) and see whether you followed everything to the letter.

Step two (only if step one has been tried and found wanting): go here to get the e-mail address of the guy who wrote it, and ask him.

Hope this helps.
