Attempt to use kernel headers from user space

Marcel Stumpel
Prodigy 210 points


Hello ,

I am trying to compile a driver and need to include some kernel includes.

I therefor have set my include path to "~/ti-sdk-am3517-evm-05.02.00.00/psp/linux-2.6.37-psp04.02.00.07/include"

However at compilation it comes with the warning "Attempt to use kernel headers from user space", but the psp is not user space according to me

What am i doing wrong??

Regards

Marcel

    See this article that discusses usage of kernel headers in a user-space application.

    Michael,

    This only applies when building applications on the host platform.

    My problem is there when I am cross compiling for Cortex.

    Regards

    Are you cross compiling kernel driver or user space application?

    Looking at your error, I believe you are trying to build/cross-compile user-space application. You have to include "~/ti-sdk-am3517-evm-05.02.00.00/psp/linux-2.6.37-psp04.02.00.07/usr/include"

    And to install header files in usr/ issue command command "make headers_install" at your kernel home directory.

    Thanks,

    I am trying to build a driver for the target,

    Meanwhile I got rid of this error by defining __kernel__ but now I get conflicting type error
