Wii page created on the wiki:

http://wiki.freepascal.org/Wii

It shows how to build a complete toolchain from the svn repository. Feel free to test it and report / correct errors

I managed to get to the build_libs.bat step, but there i get:

Yes i use d instead of c, but i changed the bat files accordingly. A note on the one should edit the .bat files accordingly to the svn folder for fpc could not hurt. Also move in your new ... could be better frased as Go to the new ...

Looking into the previouse step build_rtl.bat i now noticed the following error message:

Doing a new build_rtl.bat seems to be going better and not give the previous error. Now on to the build_libs.bat again ....

Now build_libs.bat gives no errors.

But when building the examples i get:

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..

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

[noeska]

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:
