Hi,
I'm attempting to do a build of linux for the Sega Dreamcast and I'm running into a few issues..
First, I followed the instructions on this page..
http://www.linuxfordevices.com/c/a/L...ega-Dreamcast/
It's a very old tutorial and I found that many of the items listed for download, wouldn't compile on my way newer version of GCC (the gcc listed is 3.x.x, I'm using 4.2.2).
I decided to try using the instructions posted with newer versions.. I was pretty shocked that it worked and both gcc and busybox compiled.
The next problem was the kernel, which was old as well. So, I decided to try the latest stable linux kernel (2.6.31.6). This is where I'm running into problems..
I first tried this.. make ARCH=sh CROSS_COMPILE=sh4-linux-
it gave me this output..
Code:
CHK include/linux/version.h
make[1]: `include/asm-sh/machtypes.h' is up to date.
CHK include/linux/utsrelease.h
SYMLINK include/asm -> include/asm-sh
CC kernel/bounds.s
cc1: error: command line option ‘-m4-nofpu’ is not supported by this configuration
cc1: error: command line option ‘-m4-nofpu’ is not supported by this configuration
make[1]: *** [kernel/bounds.s] Error 1
make: *** [prepare0] Error 2
After getting a tip from experts-exchange, I figured out that my host compiler was still x86. So, I changed my compiler to where the cross compiler I created was stored.. /usr/local/bin/sh4-linux-gcc. I created a symbolic link in /usr/bin for my executable and then changed my Makefile to point to my sh4-linux-gcc link.
That gave me this output..

Which maybe better than the previous, because at least I'm not getting the --with-nofpu error.
Would any of you have an idea of what I need to do to get this to compile correctly?
Thanks,
