I received an error when Error in the linking step using -lpspnet_adhocctl and the PSP SDK header file definition of "struct productStruct" in "$PSPSDK/include/pspnet_adhocctl.h"

Old code (with error?):
Code:


/** Product structure */
struct productStruct
{
   /** Unknown, set to 0 */
   int unknown;
   /** The product ID string */
   char product[9];
} productStruct;



As far as I know, in pure C syntax this is declaring an instance named productStruct in the ending part there, since this is not a typedef, so there is my problem.

I am doing C++ linkage here (and the header is extern "C", unchanged from before), so your mileage may vary if doing pure C (psp-gcc).


I had to change the header file definition to read:
Code:



/** Product structure */
struct productStruct
{
   /** Unknown, set to 0 */
   int unknown;
   /** The product ID string */
   char product[9];
} ;


The error was:


Code:

By changing the header file pspnet_adhocctl.h in the SDK, I have fixed this linking problem.

Hope this helps anyone else who is running into this. It took an hour or more to figure out (since I thought somehow the library was getting double linked somewhere, etc).

Oh I forgot here are the version details from the svn repository for pspnet_adhocctl.h

* $Id: pspnet_adhocctl.h 2433 2008-10-15 10:00:27Z iwn $

Looks like revision number: 2433

So maybe there is a fix already. I didn't have a moment to check, but anyhow if you have this issue (and using struct productStruct), you'll know when you bottom out! :P

EDIT:
Patch in unified form (Just to be complete)
