Re: [vmtk-users] Linker Error

[Mike h. <ash...@ya...>]

Dear Luca,
Thanks so much for your reply. Sorry for the double
posting to the mailing list.

Now the code compiles without problems. You certainly
found the problem.
Congratulations on the nice work. I've just started
using the toolkit and it has some very nice features.
Thanks for making it available for public use.

Best regards,
--M.H.
