Hello
I'm starting with some more complex extension for Thunderbird and I have
following problem:
The idea is to extend functionality of built-in component
(nsBayesianFilter).
I start with simple (almost empty class)
class MyClass : public nsIObserver
{..}
I add everything needed for component to register in XPCOM and try to
run, so far everything is ok, component registers itself on application
start.
Now I want my class to extend nsBayesianFilter, so I only change:
class MyClass : public nsIObserver, public nsBayesianFilter
{
...
}
When I try to run it in Thunderbird I get following message:
nsNativeComponentLoader: SelfRegisterDll(libmylib.so) Load FAILED with
error: {...}libmylib.so: undefined symbol:
ToLowerCase(nsString&)
Method 'ToLowerCase' is only used in nsBayesianFilter implementation.
When I use this method inside MyClass (anywhere in it's code) this error
changes to:
undefined symbol: GetMessageServiceFromURI
- this is another method used in nsBayesianFilter
So it looks like some kind of linker problem, maybe that's nothing with
XPCOM, but I have no idea.
I would be glad if someone could help me.
