Hi, all, I am ussing devkitpro (release 13) and followed all installation instructions on my Linux box but I am getting a linker error compiling the PCXView example for GBA:
| Code: |
splash.pcx
pcx_view.c
linking multiboot
pcx_view.o: In function `main':
/root/gba/examples/gba/PCXView/src/pcx_view.c:56: undefined reference to
`splash_pcx'
collect2: ld returned 1 exit status
make[1]: *** [/root/gba/examples/gba/PCXView/PCXView_mb.elf] Error 1
make: *** [build] Error 2
|
With the PlayBoyScout example there is a simmilar error:
| Code: |
ScoutSplash.pcx
tune.bgf
PlayBoyScout.c
linking multiboot
PlayBoyScout.o: In function `main':
/root/gba/examples/gba/PlayBoyScout/source/PlayBoyScout.c:74: undefined
reference to `tune_bgf'
/root/gba/examples/gba/PlayBoyScout/source/PlayBoyScout.c:74: undefined
reference to `ScoutSplash_pcx'
collect2: ld returned 1 exit status
make[1]: *** [/root/gba/examples/gba/PlayBoyScout/PlayBoyScout_mb.elf]
Error 1
make: *** [build] Error 2
|
I think that it could be a bin2o related problem because that program converts pcx/binary files to object ones. By the way, the "mbv2print" example compiles and links ok but when I run the "sprite.gba" generated using que "VisualBoyAdvance", the result is a white screen in the emulator (no text displayed) . Please, help.
Thanks in advance.

Perhaps, for the second one, try replacing the '_'s with '.'s.

Most of the 'bin2*' utilities transform filename dots into underscores because unlike the dot, the underscore works in a C symbol name. And it might be spitting out a symbol name other than what you expect; try using the 'nm' command on the .o file.
What command is executed under 'linking multiboot'?

Thanks very much for the idea :-). I finally found the problem with the "nm": the bin2o generates a symbol name ussing the *ENTIRE* path of the binary file not the file name. I edited the resulting .h, I changed the variable definitions and the code linked and run ok :-). Thank you very much! ^_^

I had completely forgotten about that novel effect - it had me stumped for ages a while back. I now use a Makefile in the image directory, so that the symbol names are not path dependent.

I decided to build this example to give me an idea of how to include graphic files without converting them into C-arrays. However, I get the following error:
| Code: |
F:\GBA\Projects\examples\gba\PCXView>make
make[1]: *** No rule to make target `splash.o', needed by `/f/GBA/Projects/examp
les/gba/PCXView/PCXView_mb.elf'. Stop.
make: *** [build] Error 2 |
Some more information:
-I installed devkitARM, msys and libgba yesterday using the links from devkitPro's web page.
Environment variables:
-LIBGBA = /c/devkitPro/libgba/include;/c/devkitPro/libgba/lib;
-DEVKITPRO = /c/devkitPro
-DEVKITARM = /c/devkitPro/devkitARM
-Path = C:\msys\1.0\bin;c:\devkitPro\devkitARM\bin; (plus other application paths)
Over the past few days I have been learning a bit more about makefiles, however I haven't quite grasped everything yet. I have noticed that bin2o was changed from darkfader's bin2o program into a rule in the file base_rules so I assume that the makefile in the PCXView folder would automatically generate the splash_pcx.h and the object file. Am I wrong?
It's probably something very obvious but I haven't been able to figure it out. Below are some other errors when building the other examples:
mbv2print & XbooLoad: no problems.

Did you download the base rules fix? There was a little problem with the b2o (the entire path was being put into the variable) and was fixed a few days after r13 of DevKitARM.
And try a 'make clean'. It worked for me when I tried it with the GBA examples (for some reason).

Edit: I have created a quick html page outlining the steps I took to completely install everything on a computer with no prior gba development tools. The issue wasn't resolved and I recieved the same errors. Click here to see the html file. I have also included the example, gba_rules, and base_rules files at the bottom of the page.

I remember reading that post, however I have devkitARM r14 installed. To make sure it wasn't the problem I have just downloaded devkitARM r14 4.0.1 (had just devkitARM 14 before), libgba-20050615 and the examples(from the CVS), same problem.
Here is the bin2o rule of base_rules: (file last modified: Thursday, July 21, 2005, 3:18:20 PM)
| Code: |
define bin2o
padbin 4 $(<)
$(OBJCOPY) -I binary -O elf32-littlearm -B arm \
--rename-section .data=.rodata,readonly,data,contents,alloc \
--redefine-sym _binary_`(echo $(<) | sed -e 's/^\/\([a-zA-Z]\/\)/\1_/' | tr . _ | tr / _)`_start=`(echo $(<F) | tr . _)`\

echo "extern const u32" `(echo $(<F) | tr . _)`"_end[];" > `(echo $(<F) | tr . _)`.h
echo "extern const u8" `(echo $(<F) | tr . _)`"[];" >> `(echo $(<F) | tr . _)`.h
echo "extern const u32" `(echo $(<F) | tr . _)`_size[]";" >> `(echo $(<F) | tr . _)`.h

I tried to 'make clean', however all that does for me is clean out the o files etc. is it supposed to do something else?
