Part Number: AM3352

Tool/software: Linux

Hello,

We have AM3352 based custom board running linux kernel 3.12

I was trying to compile ltp-ddt as suggested in the README-DDT in ltp-ddt source code (master branch)

I am running into following errors, Any suggestion to resolve these errors,

inter   -g -static  -L../../../lib  -lpthread
/timesys-desktop-factory/build_armv7l-timesys-linux-gnueabihf/kernel-headers/include/linux/linkage.h:7:25: fatal error: asm/linkage.h: No such file or directory
#include <asm/linkage.h>
                         ^
compilation terminated.
make[2]: *** [fbdev_tests] Error 1
make[2]: Leaving directory `/home/ankur/projects/ltp-ddt/testcases/ddt/fbdev_display_test_suite'

Thanks,

Hi Ankur,

It basically means that this file was not found in specified DIR, which gets specified when we use -I option with make. Did you try did you try "find -L -name linkage.h" ?
Also, LTP-DDT requires a host of dependencies while building. Ensure that you have right env set up. Have a look at the below link and confirm :
processors.wiki.ti.com/.../LTP-DDT

Hope it helps.

Hi Ankur

Please make sure of the below, also you might want to do a clean before rebuilding the lpt-ddt

make CROSS_COMPILE=<xxx> headers_install’ in kernel directory after the kernel is compiled. Make sure the kernel is compiled

Also with the release 3.12 the rpmsg_rpc.h is not included in the Kbuild it has to be manually copied to the ..include/linux/

the file can be find in the following directory

<linux kernel source>/include/uapi/linux/rpmsg_*

so just copy it <linux kernel source>/include/linux/

Hi Mohsen

Your both the points are right.

Thank you for reply Prabhuraj, I worked on Mohsen's suggestion and it worked for me. Basically what you suggested is also right, without header_install commands those files were not present in linux-3.12/usr/include directory, and that's the reason it didn't compile.
