DSWifi Lib - Q&A

[fischju]

I dont know if he already has an account here but Alias-Zero needs help.....He is making HelloDS ya know? He has a gui but i doubt he has ANY idea on how to implement wifi...he has been procrastinating for months now http://www.ghzsystems.com/azero/hellods/news.php

[Alias-Zero]

Don't post things like this, please.

 

If I needed help I would've asked.

[fischju]

aaw comon man.......any progress at all?

Actually yeah, I was working on it about 2 hours ago.

[fischju]

woo....what are you building it in? devkitpro? i jsut got a book on c and it will take me 2 or 3 weeks to memorize it (and the way you make progress that remarkebly fast) so i might be able to help

[yorel]

I have one more question :

 

How can i do to delete these 'warning' message :

 

1°)

 

c:/.../main.c:809: warning: 'struct sockaddr' declared inside parameter list

c:/.../main.c:809: warning: its scope is only this definition or declaration, which is probably not what you want

 

int bind(int socket,const struct sockaddr * addr, int addr_len) {;};

 

2°)

 

c:/.../main.c:1187: warning: type-punning to incomplete type might break strict-aliasing rules

c:/.../main.c:1187: warning: passing argument 5 of 'sendto' from incompatible pointer type

 

int sendto(int socket, const void * data, int sendlength, int flags, const struct sockaddr * addr, int addr_len) {... };

...

sendto(sock,sendbuf,strlen(sendbuf),0,(struct sockaddr *)&sain,sizeof(sain));

[sgstair]

yorel: do a full rebuild and post all of the warnings somewhere - I beleive you have a problem with include paths, or you may have modified part of the lib to introduce some problems (either of these would cause all of those warnings)

 

On a side note...

fischju: I know you're trying to be helpful but you're not really helping - let people speak for themselves please.

i'm actually on my home pc ( 350Mz, 98... ) I do a rebuild tomorrow (8h30 for me in belgium ^^ ) at the university.

 

the warnings are all the same. I have two times the first one and five or six the second one. I have no more errors, so i have a beautiful "ds.gba" file.

 

EDIT : So, here all the warnings message but i doubt that it will be very usefull.

The code is in the 'little demo game topic'. I send it to sgstair@akkit.org, too.

Hi.. I am having issues linking in the library.. The Arm7 builds ok, but the arm 9 doesnt. Below is the output of make... It dies with all these undefined reference to C:\DS\projects... My path is not setup that way. I changed the makefile, and the only reference I can find in my computer to C:\DS\projects is in the.lib files themselves(I ran a grep over everything)... I think i am missing something pretty basic, but I have been staring at this for a while..

 

So if anyone has any suggestions, please send them my way!

 

Good work on the wifilib.. Looks like it will be great if I can use it!

lots more undefined references follow...

[Sintax]

Those are external functions the lib uses for debugging and such, you just need to have them declared. Put this in your arm9 code:

 

extern "C" {
void * sgIP_malloc(int size) { return malloc(size); }
void sgIP_free(void * ptr) { free(ptr); }

void sgIP_dbgprint(char * txt,...) {  //Uncomment this for debug output
/*	char buffer[256];
va_list args;
va_start(args,txt);
vsprintf(buffer,txt,args);
iprintf (buffer);
iprintf ("\n");*/
}
}

Cool thanks!

 

I had the functions, just not extern'd.

 

Thanks a bunch!
