Zynq-7000 AP SoC OS - Make Errors When Building the Linux Kernel

Description

The following occurs while building the linux kernel for Zynq:

#> make ARCH=arm uImage
CHK include/linux/version.h
CHK include/generated/utsrelease.h
make[1]: `include/generated/mach-types.h' is up to date.
CALL scripts/checksyscalls.sh
CHK include/generated/compile.h
CHK kernel/config_data.h
CC drivers/char/xilinx_devcfg.o
drivers/char/xilinx_devcfg.c: In function 'xdevcfg_drv_probe':
drivers/char/xilinx_devcfg.c:1504:2: error: implicit declaration of function 'of_get_next_parent' [-Werror=implicit-function-declaration]
drivers/char/xilinx_devcfg.c:1504:5: warning: assignment makes pointer from integer without a cast [enabled by default]
drivers/char/xilinx_devcfg.c:1505:5: warning: assignment makes pointer from integer without a cast [enabled by default]

How do I resolve this?

Solution

This occurs because the GNU tool chain is not set up correctly.

For building up the Linux kernel, ensure that theGNU tools are set up properly based on the instructions from the Xilinx wiki: http://wiki.xilinx.com/zynq-tools

Once the tools are setup properly, try the build command again.
