Re: [Vala] Genie error !

[Nicolas <c r n a wanadoo fr>]

Hi,

I try to port simple pdf viewer from vala to genie.

But i have this error:

pdfview.gs:53.18-53.44: error: Too many arguments, method 
`PopplerSample.new' does not take 1 arguments
   var sample = new PopplerSample (args[1])
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^
Compilation failed: 1 error(s), 0 warning(s)

What's wrong in code ?
