Re: [Vala] vapigen and Autotools problem

Abderrahim,
  I did. In fact I needed to, in order to generate the Sql-0.1.gir and the
subsequent .girs'.

  I noted that the name the error gives to the package is not the same I
gave it when exporting it. I called it gvn-0.1 and the error talks about
Gvn-0.1, which is not a correct package name. I thought vapigen parsed the
name from the .gir and lower the case. May be the name the error gives to
the package has no relevance, I don't know.

  As you can see, I'm kind of lost right now in all this .vapi generation
thing (it's the first time I use a mailing list!), but I guess this is the
funniest part of programming. Thanks for the link, I'll give it a look.

  Thanks!

Regards,
  Alex.
