undefined symbols of modules

2006-05-30 Thread Josef Angermeier 
Hello,

when i try to compile my kernel extension as modul, i get some undefined 
references. But a look in System.map shows, that the relevant symbols 
are defined in the main kernel. Why then those undefined references ?

Any hint is appreciated!
bye

Symbol must be exported to be available for modules, just being listed 
in System.map isn't enough.

Try adding EXPORT_SYMBOL(...) for those undefined references.
