'gator driver' Complie error when enabling the GPU profiling option

Hi. developers.
Thank you in advance for your attention.


I am trying to profile the android device using ARM Streamline Performance Analyzer.
The target device is Odroid-A4 which is already tested by ARM Streamline team members (I see the YouTube video clips).
According to the ARM Streamline Menual, I compiled both gator daemon (gatord) and module driver (gator.ko)without errors and they works well.

However, I am in trouble when enabling the GPU profiling option.
According to the menual, the following two lines should be added into the gator driver make file.

=======================================================================
KCFLAGS="-IMali_driver_source_location/src/devicedrv/mali"
GATOR_WITH_MALI_SUPPORT=MALI_400
=======================================================================

So I modified the make file like that since the mali driver source code is located in that path.

=======================================================================
KCFLAGS="-I../../../mail400_driver/driver/src/devicedrv/mali"
GATOR_WITH_MALI_SUPPORT=MALI_400
=======================================================================


However, the complie error occurs since 'mali_linux_trace.h' file can't be found in path. 

=======================================================================
make: Entering directory `/home/again4you/git_work/odroid_a4_mail/kernel'
  CHK     gator_events.h
  CC [M]  /home/again4you/git_work/odroid_a4_mail/gator/driver-src/gator-driver/gator_main.o
In file included from /home/again4you/git_work/odroid_a4_mail/gator/driver-src/gator-driver/gator_main.c:151:

make: Leaving directory `/home/again4you/git_work/odroid_a4_mail/kernel'
=======================================================================


But as I mention before, the 'mali_linux_trace.h' file existsin KCFLAGS path.

=======================================================================
again4you@again4you-x86:~/git_work/odroid_a4_mail/gator/driver-src/gator-driver$ ls ../../../mail400_driver/driver/src/devicedrv/mali/linux/mali_linux_trace.h
../../../mail400_driver/driver/src/devicedrv/mali/linux/mali_linux_trace.h
=======================================================================


Should I recompile the mali gpu drivers?
Or are there any solutions to solve this problems??


Thank you for paying attentions.

    Dear Lorenzo.

    Firstly, thank you for your reply.

    After I did as you mentions,
    unfortunately, it doesn't work.(The complie error occurs like before.)

    However, given your hint,
    I found the main reason why the directory path is changed
    when I build the kernel module.

    Instead of fixing the error perfectly,
    I simply copied the 'mali_linux_trace.h' into gator-driver folder
    and modified the gator-driver source code
    since the 'mali_linux_trace.h' is linked when building.

    After modification, the compile error is disappeared.
    However, I didn't check whether it works or not with DS-5.

    I will let you the results.
    Anyway, thank you Lorenzo.
