If you guys have major questions about coding using the released lib, please post them here, so we can have a knowledge-base of sorts for people just starting out.

Full Version: DSWifi Lib - Q&A
I have some problems with compiling.
When I open my template its empty.
Were do i need to place the libraray?

Were do i need to place the libraray?
what do i need to do to get the includes to work? I assume i have to set up the enviroment variables? im just getting undefined references?
To get the includes to work, if you're working off the test app example, you'll notice there are include paths hardcoded into the makefiles. Go to the arm9 and arm7 makefiles and change the paths to where the lib is located on your computer. There's probably a better way to do this without hardcoding, but I'm no makefile expert.

Yeah, the test project does have hardcoded paths for the include files and libraries - in order to use the test project, just modify the paths in the makefile.
To make a new project, either add the include files' path to the makefile, or copy the include files into your project... then include the.lib files in your project too (could copy them to your project dir too)

When will you release your lib with TCP support ? You known that UDP isn't used at all on the internet...
The first reals internet apps will come when you will release DNS and TCP. Many devs and users are waiting for this first "useful" release for long times, and it doesn't arrive !..

actually udp is used quite a bit on the internet for streaming applications that do not require bit perfect transmission at the fastest possible speed.
edit. oh and thanks for the reply!
lol, ignore the post that was here i really shouldnt code late at night after i've been drinking! PAlib works great with wifi
i have some problem with the file sgIP_sockets.c of the lib source. I'm trying to compile ( devkitpro ) but some errors with pointers appear...
it is said :
"In file included from c:/Projects/HelloWorld/source/main.c:8:

I have the same type of problem in function 'sendto' and recvfrom.
I have tried some possibility but none seem to work...
The code :
The function sgi^p_UDP_Bind is :

The only thing I can think of is that you have your include directories set up wrong somehow. The code in the lib compiled on my end when I posted it, though there were a number of pitfalls as far as moving the project to anyone else's computer. If you can wait a few more days, the new lib version features an all new build system which should be able to build on any computer without issue.

Indeed, i change the struct sockadress_in of file and these errors have vanished... for others... Bouh Bouh Bouh...

Actually yeah, I was working on it about 2 hours ago.
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
I have one more question :
How can i do to delete these 'warning' message :

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...

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.

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!

Those are external functions the lib uses for debugging and such, you just need to have them declared. Put this in your arm9 code:
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");*/
}
}
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!
