Hi John,

I'm away from my Linux machine right now, so I can't give you a more  
detailed instruction. But based on the error you gave in your  
previous email:

Package roombaDev was not found in the pkg-config search path.
Perhaps you should add the directory containing `roombaDev.pc'
to the PKG_CONFIG_PATH environment variable
No package 'roombaDev' found

The problem is that roombaDev.pc is not within the search path of  
PKG_CONFIG_PATH.

Try:

1. Find where your library and header files are installed (the path  
can be found by opening the SConstruct script).
2. Search that directory, and find where roombaDev.pc is. Record the  
exact path to the directory containing the file. This is usually  
called pkgconfig.
3. Open up your shell's startup script - this is .bashrc or .profile  
or something similar to it, depending on your system.
4. At the end of the file, insert:

export PKG_CONFIG_PATH=/Volumes/Files/Users/jiuguangw/Programs/player/ 
lib/pkgconfig:$PKG_CONFIG_PATH

Replace my directory above with the string you obtained from step #2.  
Make sure you didn't accidently delete something from the script.  
Close all terminals and open up a new one. Try whatever it is you  
were doing before, and see if the error reappears.

To check if you followed these instructions correctly, you can do:

echo $PKG_CONFIG_PATH and see if that directory is indeed listed.

Hope this helps,

Jiuguang
