Re: [Vala] Genie xmlrpc-c bindings test

[Phil Daintree <phil logicworks co nz>]

Pancake,

I am trying to get values from the xml-rpc call that returns a struct - 
and have tried the struct_read_value and the struct_get_key_and_value 
calls which seem to be exactly what I am after. However,

# valac --pkg=xmlrpc --Xcc=-lxmlrpc_client xmlrpc-c_test.gs
/tmp/ccQFcfAa.o: In function `print_value':
xmlrpc-c_test.vala.c:(.text+0x66f): undefined reference to 
`xmlrpc_env_struct_read_value'
xmlrpc-c_test.vala.c:(.text+0x6f3): undefined reference to 
`xmlrpc_env_struct_read_value'
collect2: ld returned 1 exit status
error: cc exited with status 256
Compilation failed: 1 error(s), 0 warning(s)

However, on inspection of the vapi I note:

/* struct */
// TODO: move into StructValue

Did you ever get around to this?

If not then it looks like xml-rpc-c ain't gonna do it for me :-(

I did manage to replicate your test program in genie ok - after Jan and 
Evan's help - but if the values of the struct returned are not 
obtainable then I am back to libxml to parse the output of the libsoup 
xml-rpc call - which has also proven troublesome to this slow newbie to 
vala/genie! It's a shame as this xml-rpc-c library appears to have all 
the functions in it to do the job :-(

Perhaps I need to learn C to finish the job on these bindings and try to 
give a bit back!
