Your compiler probably provided the filename and line number for this 
warning.  I think this is in Configuration.h, and my version (current 
2.0 code, should be the same in the current 1.4 code), likely will no 
longer trigger this warning.  Nevertheless, you can safely ignore this.

Those errors are from the linker.  They mean that the linker can not 
find the compiled code representing the functions/classes you are 
calling that are in the included header files.  You will need to tell 
the linker where these library files (like libMMCore.so) are located.  
How to do that depends on your environment.  It is best to read 
documentation for your coding environment and to look at examples.

Best,
