'struct task_struct' declared inside parameter list: in /arch/powerpc/include/asm/hw_breakpoint.h"!

I'm unsing a Umbuntu machine as a build machine. There I installed the toochain from "". I got it from SDK1v8 Virtual Envioroment for PPCE500mc. (yes, using e500v2 toolchain obtained from e550mc virtual enviroment, this is not a problem).



With the toochain installed in defaul path, I was able to compile (in build machine), the linux 3.12.xx. targeting QorIQ P1010! So, I'm cross-compiling from an Unbuntu build machine to a P1010.

In MenuConfig's Linux 3.12, I selected "Freescale 85xx" as Processor Type (I'm targeting P1010). I did not set "Workarround erratum A-006184". I did set SPE enable!


Them I did: "source /opt/fsl-networking/QorIQ-SDK-V1.8/environment-setup-ppce500v2-fsl-linux-gnuspe", and

make all V=2 LIBGCC=/opt/fsl-networking/QorIQ-SDK-V1.8/sysroots/ppce500v2-fsl-linux-gnuspe/usr/lib/powerpc-fsl-linux-gnuspe/4.9.2/libgcc.a in order to xcompile the kernell.


I added LIBCC=/opt/..." n make command, because otherwise I got an error: powerpc-fsl-linux-gnuspe-ld: cannot find libgcc.a: No such file or directory

Why this happen? Why I need to pass LIBGCC like that? If I do export LIBGCC="...", it will not be accessible!


After all this, I was able to xcompile the linux 3.12 targeting P1010 (then using ppce500v2 toochain ),


After I also did also performed :

make headers_install INSTALL_HDR_PATH=$PWD/../linux-inc V=1



But my question is: When compiling a 3th party code, I'm getting "'struct task_struct' declared inside parameter list" in "linux/arch/powerpc/include/asm/hw_breakpoint.h"!

To be clear, the flag: CONFIG_HAVE_HW_BREAKPOINT is NOT set anyway.

Why this happens? Could this issue related with any configuration option in Kernel MenuConfig?

There is anyone with a tip?
