ok, thx i will see in this file. I don't want you to correct all my errors, just give me an idea what kind of error it is, just what you do for the first one. Thanks a lot.

I tried ||. mmm i will retry... The waranty message on the post 17 of this section http://www.1emulation.com/forums/index.php...11entry189957

A stupid question about Notepad programmer : How do you make a 'or' in a "while" or in a "if" ? i tried |, ||, or, v ? The 'help' don't help me... Stephen : Have you an idea about my waranty message ? Sometimes, Notepad say nothing and make the file ds.gba. Nb: i changed the main file.

Ok, For the file on windows, we have to add "#pragma comment(lib, "wsock32.lib")" after all the 'include'. Jl

It was not funny to copy all ( it takes me a lot of time ) but there were too many errors and "makefile and me", we are not good friend. Thanks a lot for the windows file, i try it tomorrow.

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. > "make" main.c c:/Projects/HelloWorld/source/main.c:809: warning: 'struct sockaddr' declared inside parameter list c:/Projects/HelloWorld/source/main.c:809: warning: its scope is only this definition or declaration, which is probably not what you want c:/Projects/HelloWorld/source/main.c:869: warning: 'struct sockaddr' declared inside parameter list c:/Projects/HelloWorld/source/main.c:922: warning: 'struct sockaddr' declared inside parameter list c:/Projects/HelloWorld/source/main.c: In function 'main': c:/Projects/HelloWorld/source/main.c:1082: warning: type-punning to incomplete type might break strict-aliasing rules c:/Projects/HelloWorld/source/main.c:1082: warning: passing argument 2 of 'bind' from incompatible pointer type c:/Projects/HelloWorld/source/main.c:1110: warning: type-punning to incomplete type might break strict-aliasing rules c:/Projects/HelloWorld/source/main.c:1110: warning: passing argument 5 of 'sendto' from incompatible pointer type c:/Projects/HelloWorld/source/main.c:1118: warning: type-punning to incomplete type might break strict-aliasing rules c:/Projects/HelloWorld/source/main.c:1118: warning: passing argument 5 of 'recvfrom' from incompatible pointer type c:/Projects/HelloWorld/source/main.c:1177: warning: type-punning to incomplete type might break strict-aliasing rules c:/Projects/HelloWorld/source/main.c:1177: warning: passing argument 5 of 'sendto' from incompatible pointer type c:/Projects/HelloWorld/source/main.c:1187: warning: type-punning to incomplete type might break strict-aliasing rules c:/Projects/HelloWorld/source/main.c:1187: warning: passing argument 5 of 'sendto' from incompatible pointer type arm-elf-g++ -g -mthumb-interwork -mno-fpu -L/c/devkitPro/PAlib/lib -specs=ds_arm9.specs main.o wifi_arm7.o -Lc:/devkitPro/PAlib//lib -lpa9 -L/c/devkitPro/libnds/lib -lnds9 -o build.elf Nintendo DS rom tool 1.24 - Oct 19 2005 20:26:11 by Rafael Vuijk (aka DarkFader) built...

Of course, i know but i had a lot of problems with that and with the makefile. I speak of them before yesterday. i try this solution ( only two files ) and it seems to work. I have only the two 'waranty' messages i told you today and a beautiful ".ds.gba" file. I remember that i had the first waranty message for the normal lib, too... so... If you want, i will send you my projects tomorrow. I will try something before. If you have files for the pc side ( for example ) i like to have a copy.

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));

Euh... you have to look your-self where the files are installed... or to use Norton and its tools...

Indeed, i change the struct sockadress_in of file and these errors have vanished... for others... Bouh Bouh Bouh... i'm going to try an other solution. i have to do a conversation between a PC and a DS... Jl

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: C:\...\source\sgIP_sockets.c:81: warning: 'struct sockaddr_in' declared inside parameter list C:\...\source\sgIP_sockets.c:81: warning: its scope is only this definition or declaration, which is probably not what you want C:\...\source\sgIP_sockets.c: In function 'bind': C:\...\source\sgIP_sockets.c:89: error: dereferencing pointer to incomplete type C:\...\source\sgIP_sockets.c:90: error: dereferencing pointer to incomplete type" I have the same type of problem in function 'sendto' and recvfrom. I have tried some possibility but none seem to work... The code : int bind(int socket, struct sockaddr_in *addr, int addr_len) { ... retval=sgIP_UDP_Bind((sgIP_Record_UDP *)socketlist[socket].conn_ptr, ((struct sockaddr_in *)addr)->sin_port, //PROB HERE ((struct sockaddr_in *)addr)->sin_addr.s_addr); // PROB HERE } The function sgi^p_UDP_Bind is : int sgIP_UDP_Bind(sgIP_Record_UDP * rec, int srcport, unsigned long srcip) I have tried a cast, &, *... i don't find.

Just, I forgot to speak about the firmware version. Be carry about that ! You have surely a old firmware. Make the test.

Ok, well. For 'wifi me' solution. You will need to have : A GBA flash card (50 euro) A PCI/PCMIA WIFI card (30 euro) like these ones on this site : http://ralink.rapla.net/ I have : -Xport 2.0B ( Charmed labs ) -Belkin F5D7000 You dl and install all the files of this web site : http://users.belgacom.net/bn967347/download.htm Attention, put the file wifime in 'data' in wmb !!! ( read instructions ) You put the file you want to test on your DS on the flash card with the software sold with your flash card. ! "ds.gba" file ! You open a "DOS window", you search the file wmb.exe with the command "cd Name_of_the_directory_you_want_enter" and "dir". Then, you write "wmb.exe -data wifime". You go on your DS, you go in "download menu". Normaly, you will have the possibility to dl 'Firefly'. Click Yes... It dl the files to make the application on the flash card starts correctly. ( in other case, you will have two white screen on your ds... sometimes only one... ) Ok ?

Need informations ? http://www.aaronrogers.com/nintendods/index.php Pass me -> need some materials,... Flash me -> some problems ? Wifi me -> You put the ds.gba file on your gba flash cart and you dl wifime on your ds via WMB. ( so you need a correct Wifi card ). ok ?

Please make a ".ds.gba" file for the guys who use wifime and a gba flash cart.... :-s Thx. Jl EDIT : Thanks for the file and the rapidity °|_°

Well, i have to realise a connexion between a PC and a DS. I though to do a little game but i have some difficulties... Sypherce told me to go at http://akkit.org/dswifi/udp_test.c but : - what is types.h ? --> stupid question ( is-it possible to send me that file jeleroy@ulb.ac.be ? ) - it is ok for all WIFI PCI card or only ones with RT2500/RT2560 chipset. Jérémy.

Thanks.

Hello, I have some stupid (?) questions. Could you answer me ? What are exactly the BaseBand and the RF chips ? What are spinlock and WIFI_AUTHLEVEL ? ( wifi_shared.h ) I know what is SSID but BSSID ? RSSI ? I read somewhere that only the ARM7 was able to use Wifi's registers but i see the file wifi_arm9.h and wifi_arm9.c. So, i'm a little disappointed. There is a great function in wifi_arm7.c : Wifi_ProcessReceivedFrame. Is-it possible to have more explanation about the code ? what is for ?

Surely. I told him that, already. For the moment, i'm studying for my exam's... they will be hard... So, I will take a look to all the projects with wifi after these. Thanks. I have chosen some PCI card but i will buy one after these, too.

I'm trying to succeed my fourth in engineer. This project has to prepare students to the big one...

So, if that application is selected, i will have to find a trick... I will contact Natrium. He seems to be very nice. Nb : for the project, it's the Ds's wifi that i have to use.

I guess that there is some other thing controlling them and using wifi but actually, i ask myself if it is already defined. I must ask that to the person in charge of that.
