Kernel 2.4.XX compilation

Hey, I have another error when I want to include DMA support:

sh3-linux-gcc -D__KERNEL__ -I/home/ivw/shlinux-20050128/linux/include
-Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing
-fno-common -fomit-frame-pointer -ml -m3 -pipe   -nostdinc -iwithprefix
include -DKBUILD_BASENAME=rtc  -c -o rtc.o rtc.c
sh3-linux-gcc -D__KERNEL__ -I/home/ivw/shlinux-20050128/linux/include
-Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing
-fno-common -fomit-frame-pointer -ml -m3 -pipe   -nostdinc -iwithprefix
include -DKBUILD_BASENAME=dma  -DEXPORT_SYMTAB -c dma.c
dma.c: In function `setup_dma':
dma.c:55: `INTC_IPRE' undeclared (first use in this function)
dma.c:55: (Each undeclared identifier is reported only once
dma.c:55: for each function it appears in.)
make[1]: *** [dma.o] Error 1
make[1]: Leaving directory
`/home/ivw/shlinux-20050128/linux/arch/sh/kernel'
make: *** [_dir_arch/sh/kernel] Error 2

The SH7727 (SH3-DSP) actually has a DMAC I don't understand what that
error means...

OK, now you are missing the manifest constant INTC_IPRE which is
defined in
include/asm-sh/irq.h and include/asm-sh/irq-sh7300.h.

What option didn't you select this time?

I have no clue on what else is missing.

Should I post my .config file?

Let me know,

This error is the critical one. It appears that sh-sci.c requires
that you include into your Linux build the components that defines the
serial_console_wait_key() function .

serial_console_wait_key() is defined in drivers/char/serial_tx3912.c
and also in  drivers/char/au1x00-serial.c (along with the config.c for
a couple of the various supported architectures). I guess that you will
have to select the appropriate driver and use it in your build



This refers to the fact that serial_console_wait_key() is undefined, so
the structure initialization
  wait_key:serial_console_wait_key
fails



Just warnings that the programmer allocated two variables but didnt use
them. These don't affect the success or failure of the compile.




All in all, you didnt select everything required to build your Linux
system. Go back to config/menuconfig/xconfig and select the option that
provides the serial console support. Then try the make again
