[linuxdc-dev] cvs and kernel building

[Jeff T. <jw...@me...>]

I recently placed this as a comment to the cvs source being available on
sourceforge but figured this would be a more appropriate place to put my
questions.

 First a note about my setup

RedHat 6.2
binutils-sh4-linux-010127-2.i386.rpm
gcc-sh4-linux-2.97.001120-3.i386.rpm
gdb-sh-linux-5.0.001127-2.i386.rpm

Please note that the gcc is actually -2.deb version, but alien increased
the number
when I converted it. I was unable to find the -1 version as listed in the
HOWTO
document.


When I compile the firstkernel tarball's source I get the following error:

make[1]: Entering directory `/root/box/kernel/arch/sh/kernel'
sh4-linux-gcc -D__ASSEMBLY__ -D__KERNEL__ -I/root/box/kernel/include -ml
-m4-nofpu -c -o entry.o entry.S
entry.S: Assembler messages:
entry.S:375: Error: must be @(r0,...)
entry.S:376: Error: must be @(r0,...)

make[1]: *** [entry.o] Error 1
make[1]: Leaving directory `/root/box/kernel/arch/sh/kernel'
make: *** [_dir_arch/sh/kernel] Error 2

I assume that this is caused by the problems with different gcc versions
as
mentioned in the HOWTO document. Has anyone else got this going with this
version of gcc from m17n.com?

I also retrieved the cvs source and attempted to compile. In this case I
get a failure
in the make dep:

make[4]: Leaving directory `/root/box/linux/net/bridge'
make -C core fastdep
make: Entering an unknown directory
make: *** core: No such file or directory. Stop.
make: Leaving an unknown directory
make[3]: *** [_sfdep_core] Error 2
make[3]: Leaving directory `/root/box/linux/net'
make[2]: *** [fastdep] Error 2
make[2]: Leaving directory `/root/box/linux/net'
make[1]: *** [_sfdep_net] Error 2
make[1]: Leaving directory `/root/box/linux'
make: *** [dep-files] Error 2

Also when I do a make vmlinux not suprisingly I get a:


[root@c895938-a linux]# make vmlinux
sh4-linux-gcc -D__KERNEL__ -I/root/box/linux/include -Wall
-Wstrict-prototypes

/root/box/linux/include/linux/fs.h:447: field `shmem_i' has incomplete

/root/box/linux/include/linux/fs.h:699: field `shmem_sb' has incomplete
type
In file included from /root/box/linux/include/linux/mm.h:4,

etc..etc..

So, the next question is, has anyone had any luck in building these
sources? Any
tips or thoughts are welcome!

I'll be spending some time this weekend working on these problems and
trying to get
things going. I work for a OS level computer security company and have two
other
kernel developers who are going to be getting linux going on their systems
(we want
to get our security extensions on the dreamcast just for fun!), so
hopefully we'll be
able to make a few substantial contributions to the effort.

Thanks for any help!
