Dear Rooters'
The following code is used to generate a shared library. During the
compilation, it gives some warning messages like:
** Note: operator new() masked 1c
** Note: operator delete() masked 1c
** Warning: Link requested for undefined class ooImp FILE: LINE:0
and finally generate the library "oo.sl". But after I load it into root
using gSystem.Load("oo.sl"), and type :
-- .class test
it shows:
** Error: class,struct,union or type test not defined FILE: LINE:0
Could you tell me what's the problem ?
Sincerely yours
