GP2X How To Use Visual C++ 2005 Express

[Kalakian]

Still having a right game getting this setup! I think I'm half way there...GCC Linker doesn't even seem to exist :S

​

Are you trying to add both the custom rules, GCC Compiler and GCC Linker? Can you give us a better idea of what you have working / not working so that someone can help you out. Is it compiling but not linking, or not doing either?

 

[mattyrb]

I'll post a full lowdown on my problems tonight I'm at work right now hehe

 

[mattyrb]

right sed doesn't work at dos prompt....now is that because its called sed-3.59.exe and not sed?

 

[slygamer]

Yes. Rename the exe to sed.exe.

Kalakian, I will add your GCC Linker rule to the wiki tonight.

 

[mattyrb]

anyone got a test project i can try to build to see if i've got this thing working now ?

"hello world" ? lol anything :lol:

 

[slygamer]

When I get home tonight (just got to work), I can post my Minimal SDK example if no-one else posts anything in the meantime.

 

[Kalakian]

Kalakian, I will add your GCC Linker rule to the wiki tonight.

​

Cool, I have never updated a wiki b4 and wouldn't know where to start. I'm not much for documenting, I just hack things together till they work and leave it to someone else to document properly

​

The wiki has a basic hello pixel program, which I modified to show a square in this thread: http://www.gp32x.de/board/index.php?showtopic=22436

Makes no sense to me not being a visual c++ person

You haven't told the GCC compiler where the SDL.h file can be found. This is done through the Additional Include Paths property in the GCC Compiler project settings.

Hint: Put your projects in a directory that has no spaces in it. GCC may complain about the spaces.

 

[slygamer]

I've updated the wiki with the linker rule made by Kalakian. I merged it into the one rule file.

Here is a simple project using the new rules file on the wiki.
http://users.on.net/~sly/gp2x/test2.zip
Unzip this to somewhere on your drive, load it into VC++2005 and press F7 to build. It should spit out a test2.gpe file the debug directory. Put this on your GP2X, select Games and run test2. You will get a black screen with a single dot in the middle. Press the A button and the dot changes colour. Press L and R together to exit back to the menu.

yep...but...

has anyone been sucessfull compiling an app that uses:

SDL_Mixer / SDL_Image

 

[mattyrb]

Right I've successfully set the damn thing up!

I'd just like to say you lot have been a great help so far! This community sure does have alot of friendly, patient, helpful people in it!

Any ideas for how i can test my applications other than owning a GP2X....I'd like one but not right now hehe When I've got the cash maybe!

Argh - I am so close to getting SDL to work with this 2005 Express setup.

I have this .. in my additional paths for the GCC Compiler include

C:\devkitpro\devkitGP2X\include;C:\devkitpro\devkitGP2X\include\SDL

so it finds the SDL headers just fine.

I have this .. for my GCC Linker library paths.

C:\devkitpro\devkitGP2X\lib\

If you check in this directory you'll see.. libSDL.a, libSDL_image.a....

Except the compilation process reports this...

------ Build started: Project: GP32, Configuration: Debug Win32 ------
Linking GP32.gpe...
Debug\Main.o: In function `main':

Any ideas? Any help apppreciated.

any way to make this work with visual studio .net 2005?
or vc++ 2005 == vc++ .net 2003 ?

​

Not me, and not using VC++ 2005 either. But anyway, if anyone manages to get them working, please tell us! From what I've read, there's plenty of people waiting for a working version of those libraries (me included ). Thanks.

Hey does that mean you got the core SDL library working with Visual Studio Express 2005?

See this link. Take a look around the site - lots of good stuff to get your teeth sunk into.

​

Nope. I'm using Code::Blocks to code in XP, and then plain makefiles through CygWin to generate the GP2X version.

Have you added SDL and SDL_image to the Additional Dependencies in the GCC Linker settings? It needs to know which libraries to link, not just where they might be.

Visual C++ 2005 Express is a cut-down version of Visual Studio 2005. 2003 does not equal 2005.

Visual C++ 2003 does not have the custom build rules feature that we use for telling the IDE to use GCC instead of the built-in C/C++ compiler. In Visual C++ 2003, you must create a MakeFile project in order to use GCC.
