Hi,

I want to use the danzeff keyboard in my homebrew. I included the danzeff.h and I added the danzeff.o in the makefile. I tried to compile without any additional commands first to check if the integration was successful but my code does not even compile at this stage. The following errors appear. Can anyone help me?

Just fix the errors mentioned in the listing. If you can't fix a redefinition of a symbol when you are given the file and line number, you aren't ready to be programming, much less programming the PSP.

[kasikeeper]

Ok, maybe I am not ready yet but I want to learn. Can you tell me how to fix a redefinition of a symbol?

[J.F.]

Look at where the error message says the redefinition occurs, go to that line, and put // at the start to make it a comment. Repeat.

[kasikeeper]

Ok, that was easy. I was not aware that I just have to comment the enumerations out.

The only remaining errors are:

/cygdrive/c/pspdev/bin/../lib/gcc/psp/4.0.2/../../../../psp/include/SDL/SDL_stdinc.h(61) : column 22 : error: strings.h: No such file or directory
In file included from main.c:20:
danzeff.h(58) : column 27 : error: SDL/SDL_image.h: No such file or directory

The missing header files are not part of my pspdev installation. I used the PSPDevLibInstall tool to get the required libs but probably that is not enough. Can you help me one more time?

By the way, where can I find the most current version of the danzeff OSK???

Thanks a lot!!!

[J.F.]

SDL_image is built and installed by the psplibraries toolchain.

Hi again,

I just doen't seem to get forward. I managed to include danzeff without problems but when I try to load danzeff I get the error:

main.c:(.text+0xa58): undefined reference to `danzeff_load'


Can you help????

Can you help?

[J.F.]

Well, either you got a bad copy of the danzeff files, or you edited that part out by accident. Here's the latest copy of the danzeff files I have.

Thanks a lot for the download link. I had the same errors however. I managed to ged rid of the error by putting a void before danzeff_load(). I can compile without problems now but the keyboard is not displayed. My current code snippet now looks like

#include "danzeff.h"
#include "graphics.h"

...

void danzeff_load();
if (!(danzeff_isinitialized())) printf("ERROR");
void danzeff_render();

flipScreen();


I guess I have not to initialize any further graphics as i use the graphics.h (from the psp-programming.com tutorial) which does the job already. The danzeff_isinitialized() however returns false but I don't know how to get forward now.

Sorry for bothering you all the time. I feel a little embarassed about asking so many questions already...

[J.F.]

Sticking "void" in front of the calls is just changing them from function calls into function prototypes. Get rid of the voids and do it properly. I suspect you don't understand C enough yet to be doing whatever you're trying to do. You either need to post a lot more of you code or take some more C classes.

[kasikeeper]

OK, I am getting closer. I set up a new development environment and the library errors seem to be gone. I am using the newest danzeff sources found at

https://svn.sourceforge.net/svnroot/pspradio/trunk/PSP/SharedLib/danzeff

and I use GU as the rendering machine. I did not add any extra GU setup commands because I use graphics.h (downloaded from the psp-programming tutorials) and the graphic init commands there already set up GU.

My current code besides the #include "danzeff.h" is:

....

danzeff_load();

while(!done)
{
if(danzeff_dirty())
{
danzeff_render();
flipScreen();
}
.
.
.
}

The code compiles without errors. danzeff_initialized returns true which is good but the OSK is not displayed. I guess there is something wrong with the GU setup.But I haven't got a clue about GU. Does someone know if the graphics.h is actualy appropriate for this? Which modifications would I have to perform with the standard graphics.h for psp in order to use it for danzeff?

[J.F.]

EDIT: I see you did mention danzeff_isinitialized() (sort of). I would guess at this point that the GU isn't setup correctly. You're not giving us enough to really make any real suggestions. You might look at how SNES9x uses danzeff.
