[asterisk-dev] compiling Dahdi on blackfin

[Dan Amarandei]

Hi everyone,

I am having  issues with cross compiling DAHDI on the blackfin processor and
Tzafrir suggested I post my question here.

Here is what I get when I simply run make KSRC=wherever my uClinux kernel
 is - right in the dahdi linux directory:

As an alternative I have copied the dahdi-linux-2.2.0.2/drivers/dahdi into
uClinux-dist/linux-2.6.x/drivers and added a line in
uClinux-dist/linux-2.6.x/drivers/Makefile like this "obj -$(CONFIG_DAHDI)
  +=dahdi/"  and in uClinux-dist/linux-2.6.x/drivers/Kconfig like this
"source "drivers/dahdi/Kconfig"". When I run make xconfig in the
uClinux-dist folder  Customize kernel settings now shows DAHDI support  with
DAHDI Echo Cancelers as a submenu, DAHDI transcoding support as the second
submenu, and Xorcom Astribank Support as a further option. I disabled
everything but the DAHDI transcoding support - yet when I go on to make I
get build errors where it looks like include folders are not there.

All I am really looking for is to have the DAHDI basics only for Asterisk
1.6 however  ultimately I need to port the wcfxs driver - any help would be
greatly appreciated.

Thanks.
