Hello All,
Firstly I would like to say that I am new here and fairly new to
Yocto, so I do apologize if this is the wrong board for this question.
(And if it is could someone direct me to the correct board?)
Background on me: graduated OSU before Fall 2015 started with a BA
Computer Science Computer Systems - minimal yocto ~2 months baby level
stuff.
Some background on the issue: I am following these directions
http://www.crashcourse.ca/introduction-linux-kernel-programming/lesson-11-adding-proc-files-your-modules-part-1 to
create a jiffies utility folder in /proc as a precursor to a larger
project. I have made the appropriate changes within the
/usr/src/kernel/fs/proc folder and now I am trying to compile and load
the module, to place a jiffies entry in /proc. Well when I run 'make'
from /usr/src/kernel/ I get most of the way through, way past building
my jiffies.o file in user/src/kernel/fs/proc, without errors but
toward the end I get the following error.
LZO arch/arm/boot/compressed/piggy.lzo
/bin/sh: lzop: command not found
/usr/src/kernel/arch/arm/boot/compressed/Makefile:193: recipe for
target 'arch/arm/boot/compressed/piggy.lzo' failed
make[2]: *** [arch/arm/boot/compressed/piggy.lzo] Error 1
/usr/src/kernel/arch/arm/boot/Makefile:52: recipe for target
'arch/arm/boot/compressed/vmlinux' failed
make[1]: *** [arch/arm/boot/compressed/vmlinux] Error 2
/usr/src/kernel/arch/arm/Makefile:305: recipe for target 'zImage' failed
make: *** [zImage] Error 2
I had not though to try to 'make' in this manner before I attempted
this project so I don't know if this worked originally. My yocto build
is located on one host machine and the actual implementation / working
area is on another with an arm processor. I ssh into my device that
the yocto build is for and from there I work with the code. If I try
to 'make' on the host machine I get an error that it can not
find/access some generated files so hat option I think is out and
googling only resulted in that type of solution one to be done on my
host machine.
Has anyone ever had this problem before or could point me in a better
direction?
If you are generating a module that needs lzo compression .. does your host
distro have lzo installed ? If the kernel recipe you are using doesn't
specify
lzo-native as a DEPENDS, then there won't be the right tool available to
do that
compression.

Thank you.
