It was getting ready to compile but I got these errors:

and here is the code, slightly edited from your bgdi source. you say that bgdrtm needs to be compiled, but i saw nothing in there that should be for bgdi compiles it right?

we better advance step by step.

oh no no no no no i dont learn that way. i got rid of that hello world, that thing was gay. yes i am just downright compiling bgdi and i have 1 error and 1 warning. codeblocks is the IDE set up to compile it in cygwin and kos
The purpose of the "Hello, World!" example is not to determine if you like getting laid with men or women but to determine wether your compilation toolchain is working correctly. Also, you get a very simple working binary that you know has no place for failure that you can convert into the machine's native binary format. That way if things aren't working you can directly assume that it's nt the toolchain that is working wrong.

and here is the code, slightly edited from your bgdi source. you say that bgdrtm needs to be compiled, but i saw nothing in there that should be for bgdi compiles it right?
All those errors are from a missing bgdrtm. If you have a look at the bgdrtm source you'll see functions named like that: bgdrtm_entry, dcb_load, dcb_load_from, bgdrtm_exit and so on.

Again, I advise you to try to compile a very simple test program to check if you can create valid DC binaries but anyway, if you want to go the hard way and not check things are working fine before assuming they are (VERY bad idea!) I'll tell you that the next step is to compile bgdrtm alongside bgdi.
To do so, you have to compile all the source files that comprise bgdrtm into a static library and then link bgdi against that static library or you can compile all the .c files from both bgdrtm and bgdi together, using the BGDRTM preprocessor macro. The first choice is much cleaner. Those files are the ones defined here:
http://code.google.com/p/bennugd-monolithic/source/browse/trunk/core/bgdrtm/Makefile#71
(For now just ignore the ones that are in the modules/ directory, also you probably want to ignore the source file in the 3rdparty directory but that depends on which libc your DC SDK is using).
And the preprocessor macros you have to define are as (choose only those that apply) defined here:
http://code.google.com/p/bennugd-monolithic/source/browse/trunk/core/bgdrtm/Makefile#43

Please report on advances.

I don't wanna be rude, but really I think than DoctorN can't compile a Bennu for DC because he need to practice and learn much more about programming languajes.

You're free to learn the hard way if you want to.
I already told you what you have to do next: compile bgdrtm and bgdi into the same binary in your IDE. There's no single .c file that will do that for you: you have to compile many of them inside one single binary.

DoctorN, if FreeYourMind said it... maybe you must listen him... FreeYourMind need learn lot of about this topic, but even need it, he know mucho more that you.

you think that this is only, put sources in your cross-compiler and do make? if you think, you really do this because you think that I'm a bastard... I must say that you are really wrong... really wrong... this jobs isn't a easy task, even for an expert programmer...
I don't do it no for I'm a stupid bastard, but this will require a time that I haven't at this moment, and the cost (job) don't justify the prize for me...

Just to illustrate Splinter's point, it took me MONTHs to get a bgdi+bgdrtm (without ANY module) running in the Wii and around a year to take a port to a usable state.
It's just not reasonable for you to expect to be able to complete the DC port in a few days, specially if you have no prior experience in cross-compiling or programming for embedded systems.
You say that that's the way you learn but you're making it really hard for yourself.
Anyway, it's up to you.

splinter have reason.. this project its free  .. time not available..




but...



our team, will compile this weekend bennu with "windows ce - official sega sdk"
its illegal but more practice.. wil be.. how a unofficial port.. 

dont worry be happy

our team, will compile this weekend bennu with "windows ce - official sega sdk"
its illegal but more practice.. wil be.. how a unofficial port.. 


its not illegal anymore lol. I didnt mean to snap at you Splinter if thats how you interpreted it. I was asking a russian programmer by the name of SWAT (who created an operating system to replace the dreamcasts bios). He ported fenix over and here is his modified source code of fenix http://www.dc-swat.ru/download/dc/fenix/Fenix_v0.93_updated_source_for_DC.tar.bz2

If you use the wince kit, it cannot be tested on an emulator.

Please look at SWAT's code, everything dreamcast specific is there.

For example, the controls used should appear in there, L and R arent there but thats probably because they arent set in lol. SDL_DC_R should be the tab key and SDL_DC_L should be the backspace key. You mat want to rename some of the controls based on what chuy had here: http://chui.dcemu.co.uk/sdl.html so one does not get confused when making a 4 player game.

The game does not need to be compiled on the dreamcast, simply because it shares things with windows, you could use the latest fenix pack for the fenix version (and bennu for the bennu version when that one arrives).

SWAT made a folder called dll, he coded it so custom dll's made for the dreamcast version will load.

play_wav did not work in his current release

Nor could I find the code that supposedly looks for autorun.dcb lol

His folder is not complete, you will need the other parts of fenix, but anything edited for the dreamcast is in those folders

will there be a .dll for playing a movie file from the get go? someone told me they got smpeg compiled once and at 320x240 it ran at 15fps, which i guess is ok lol.

Do you think you can make a program to change the display VMU?
