FPC 4 Wii

[Legolas]

Ok, thanks for the suggestions. I have edited a little bit the page, following your advices

The error you get comes in two cases: 1) the rtl isn't built at all or it misses some units or 2) the file fpc.cfg is missing or it points to the wrong paths.
Please, make sure that in C:\fpc4wii\units\powerpc-wii there are system.o and system.ppu.

In the meanwhile, I just found some problems (a couple of functions I forgot to translate...) on libogcfpc. Please, download gccore.inc again from the svn trunk

After doing a update to head on the fpc sources i decided to to a new build_rtl.
Now it think it fails on:

d:/fpc4wii/bin/powerpc-wii/ppcppc.exe -Twii -Ppowerpc -XPpowerpc-eabi- -Xr -Fi..
/inc -Fi../powerpc -FE. -FU../../rtl/units/powerpc-wii -Twii -CX -XX -O2 -dpower

A file not found does not seem good in my opnion. Although i do not see something like a build error.

Definitely not. The problem is in the batch script: it searches the units in a folder that does not exist...

XCOPY /Y %FPC_SRC_DIR%\rtl\wii\units\powerpc-wii\*.* %FPC_INST_DIR%\units\powerpc-wii\

should be

XCOPY /Y %FPC_SRC_DIR%\rtl\units\powerpc-wii\*.* %FPC_INST_DIR%\units\powerpc-wii\

I have fixed the wiki too. Sorry for the inconvenience

Ok applied that fix and started from scratch and i now seem to have an almost working fpc4wii compiler.
The audio examples now compile.
But now i get some errors on the usbgecko examples:

That example needs to be fixed. Maybe I have missed to link some library or the linking order is wrong, but I haven't investigated further, because I'm focusing on the library itself.

EDIT: seems that this could be fixed by passing --gc-sections to the linker, or rather by passing -k--gc-sections to the fpc compiler. It is only matter to add this parameter to the makefile.fpc:

[compiler]
options=-Xm -k--gc-sections

then regenerate the Makefile as usual, by

fpcmake -r -w -Twii

[noeska]

Thanks.

I am not that good with fpcmake and the likes.

I now run into problems when executing the fpcmake -r -w Twii as it then states:

Processing Makefile.fpc
Error: Target "wii", package "libogcfpc" not found

Just removing usbgecko examples gives and not found for usbgecko.

Maybe i should compile the examples one by one. :-)

Anyways i am going to try out the working examples on the wii this weekend.

Is not the gecko some kind of debug device?

[Legolas]

Yes, it is. BTW, as you have noticed, things need some work here and there. I'll try to fix these issues in the next days. Let me know if the examples are running fine on the Wii
