When trying to call a member function in gcc-2.2.2, gdb-4.7 (on a sun4)
replies systematically as in the folloing example:

(gdb) print f.y0(3,2)
Structure has no component named y0.

Please, tell me that I am not the only one the have these problem !!!
What can I do about it ?

Thanks.

Please reply to casadei@cesena.mit.edu

 The answer is - it really doesn't know that there is an element y in
that structure. (I'm not trying to be obvious). I had the same problem
with some code I was writing on a Sun with gcc-2.2.2 and gdb-4.6. You
must use the syntax:
 (from a previous mail message)
 I figured out the problem. I don't know why yet but structures which
get "typdef'd" get handled as "unknown type" by gdb. By just stating
them as "struct my_struct { ... };" everything was fine. Live and
learn.


This should take care of your immediate problem - apparently the other
syntax causes gcc to simply malloc storage - essentially untyped which
has a structure that it only knows the size of - not the members.

Let me know if this is still a problem.
