sample showing valac 0.5.2 emitting calls to non-existing method (386 bytes, application/x-compressed-tar)
2008-12-14 08:13 UTC, Martin Olsson 		Details

Description Martin Olsson 2008-12-14 08:12:16 UTC 
Please describe the problem:
This vala sample code causes valac emit calls to a non-existing method (g_data_input_stream_construct). No warnings are printed by valac.

I'm expecting valac to either show a compilation error, or if this code is valid then emit code that gcc can compile.

Steps to reproduce:
1. 
2. 
3. 


Actual results:


Expected results:


Does this happen every time?

Chaining up constructors is not supported yet for library classes.
Comment 3 Michael 'Mickey' Lauer 2009-10-08 12:20:18 UTC 
Meanwhile, Vala emits an error for your test case:

main.vala:8.3-8.32: error: chain up to `GLib.DataInputStream..new' not supported
		base (new MemoryInputStream());
		^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The original issue remains open though.

Can you elaborate? Chaining up is not supported due to GObject limitations. Vala now reports an error instead of generating invalid C code. GObject-style chain up is supported by using of Object (...); I'm closing this as duplicate. Feel free to reopen the bug if you think that's incorrect.
