s3c2440camera-r5 compile problem

Forum: Linux
majid 
hi

I'm newbi to linux, sorry. what should I do?

root@dab-desktop:/opt/FriendlyARM/s3c2440camera-r5# make
make -C ../linux-2.6.32.2 M=/opt/FriendlyARM/s3c2440camera-r5 ARCH=arm
modules

Well Makefile looks little bit strange. Before running make run in your
mini2440 kernel dir following:
make mini2440_defconfig ARCH=arm; make prepare ARCH=arm
CROSS_COMPILE=arm-linux-<depends what's the prefix for your compiler); make
ARCH=arm CROSS_COMPILE=arm-linux-<same as before>

Then in camera directory:
KERNEL_DIR=<path to mini2440 kernel> CROSS_COMPILE=<same as upper> make

majid 
still there are some strange things. I set PATH to linux-2.6.32.2 kernel in
.profile and has restarted but:

why it has referred to "/usr/include/string.h" instead of my defined PATH ?

majid 
.profile is

# mini2440
PATH=$PATH:/usr/local/arm/4.3.2/bin/
PATH=$PATH:/opt/FriendlyArm/mini2440/linux-2.6.32.2

(also, I have used correct char case for "FriendlyArm". Forget about first
post with "FriendlyARM".)

open-nandra 
Well it build fine here. but I'm not using FriendlyARM cross compiler.
Anyway try to add -I<path to include> to Makefile.

majid 
kindly, what cross compiler do you use?

open-nandra 
I build one using buildroot tool and use across all projects.

majid 
#in makefile
EXTRA_CFLAGS += -I/opt/FriendlyArm/mini2440/linux-2.6.32.2

but still there is problem!

open-nandra 
OK lemme check with friendlyarm cross-compiler.

open-nandra 
Well I can't compile with current frienldyarm toolchain. I get:
arm-none-linux-gnueabi-gcc: Internal error: Segmentation fault (program
cc1)
Please submit a full bug report.
See <https://support.codesourcery.com/GNUToolchain/>; for instructions.

Anyway test_capture is build or not on your side? Warnings could be omitted
;).

marek

majid 
thanks for your time

here has created a 11.8KB test_capture file

I'm new to Linux, is it sufficient ?

open-nandra 
If it's created should be sufficient ;). Load it to board and run it.

majid 
again, for review

finally
there is .o files, a .ko file and test_capture file

open-nandra 
Well as I said. Load it try it. If it works it's good. This is just
warnings not errors.

majid 
yes, I will do it.

I know, [warning: unused variable 'x']. Absolutely, it is not important
here.
But, what about [WARNING: "X"
[/home/dab/project/mini2440/s3c2440camera-r5/s3c2440camera.ko] undefined!]
?

While, I see s3c2440camera.ko file in the proposed directory!
