Re: No dictionaries for std::complex

Thanks Philippe,

it seems then, that I have the right implementation, but anyway, I thought this was fixed due to the following post: http://root.cern.ch/phpBB3/viewtopic.php?f=5&t=9618, where you mention:

"Hi,

The ProcessLine call is only needed to work around a bug in the library autoloading setting affecting only the std::complex classes (This is fixed in the trunk, revision 36617 and up).

Cheers,
Philippe. "

Maybe I misunderstood it? It is not clear to me when should I manually enforce a dictionary should be loaded.

Cheers,
Marcelo
