I'm stuck, I honestly doesn't know what gcc wants from me. Any ideas? Thanks...

EDIT: I realize that the vbox bit is redundant, but it should compile if everything else is correct...(I think)

you passing pointers-to-pointers (Ewl_Widget**) due to the extra refrence upon calling the function...

this is a common C error... all you have to do is say it outloud:
Ewl_Widget *win -> "Ewl_Widget pointer"
& -> "address of"
&win -> "address of Ewl_Widget pointer"

the third one doesn't make sense... a pointer *is* an address... just remove the "&" on all those calls having the problem

Okay, that makes sense. Originally, I had it without the &'s. It wouldn't show the button, and probably not the container (its invisible). However, when I have everything in the main function, it works flawlessly. I'm truly stumped, and I would hate to have everything in the main function, because thats no good! Anyway I'm still stumped. any more ideas??

EDIT: I hadn't realized that it was still compiling despite the warnings, so when I did, I ran it. but It didn't run correctly, I got a message in the terminal telling me that ecore_hash_set() was called with a hash value of null, also telling me to "please fix my program".

I think the problem has been solved...my problem was allocating the ewl widgets before ewl_init...I will try this when i get home from work
