Hi, there,
Now I am working on cross-compiling v5.9 for armv7. What I have done is as
following.
1. download source code of v5.9
# cvs -qd anon...@anoncvs4.usa.openbsd.org:/cvs checkout -rOPENBSD_5_9
-P /usr/src
2. make cross-compiling tool-chain
# cd /usr/src
# make KERBEROS=no TARGET=armv7 cross-tools
after it's done, a new folder is created under /usr/cross
# cd /usr/cross
# ls -al
total 12
drwxr-xr-x 3 root wheel 512 Jul 26 01:06 .
drwxr-xr-x 17 root wheel 512 Jul 26 01:06 ..
drwxr-xr-x 13 root wheel 512 Jul 26 01:13 armv7
# ls -al armv7
total 64

3. compile kernel for armv7
# cd /usr/src/sys/arch/armv7/config
# cd config RAMDISK
# cd ../compile/RAMDISK
# make clean; make
cat ../../../../arch/arm/arm/genassym.cf
../../../../arch/armv7/armv7/genassym.cf | sh ../../../../kern/genassym.sh

switch
*** Error 1 in /usr/src/sys/arch/armv7/compile/RAMDISK (Makefile:439
'assym.h')
I don't really know what's going on. Is there a step-by-step procedure of
how to make a kernel for armv7 or give me a hand upon this error?
Thx.
Regards,
Eaton
