Has anyone else seen this error message when compiling an out of tree module?

Hi! I’m having the same error when trying to compile a out of tree driver.
Have you found the solution?
I’m also using the kernel from RobertCNelson/armv7-multiplatform.
Thanks!

Hi Jake,

Yes, I did find a solution! Using the cross development tools downloaded by Nelson’s script makes things work correctly. This the script I’m using to build drivers:

CROSS_COMPILE_PATH=/usr1/github.com.RoberCNelson.arm7-multiplatform/armv7-multiplatform/dl/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-
make -C $KERNEL_ROOT M=$(pwd) ARCH=arm CROSS_COMPILE=$CROSS_COMPILE_PATH
