Re: plugin example problem under linux

Ok... 
I still have some trouble with the source version (I get a segmentation fault) 
but finally I managed to get the sample plugin work. The problem was, that in 
the c++SampleDemo.tz was written:

@plugin "c++Sample_plugin.o" (cppSampleLoadFunctions).

but it seems that it should be the shared object file and not the object file:

@plugin "c++Sample_plugin.so.1.0" (cppSampleLoadFunctions).

this works fine, now.

Best regards,
	Marc.
