Compile Error with SDK Example Code

[duglew60]

I'm using the gnu toolchain, arm-gnu-toolchain-13.2.Rel1-x86_64-arm-none-eabi, on WSL2 Ubuntu to compile the example code that is with the SDK_2_9_0_MEK-MIMX8QX.  The specific code I'm trying to build is rpmsg_lite_str_echo_rtos and I've also tried the hello world example.  I'm using the build_debug.sh script.  I'm getting the following error:

MIMX8QX6/utilities/fsl_sbrk.c:22:1: error: unknown type name 'caddr_t'

From the research I've done this is related to BSD-ism in older code.  Is there an environment variable I can set to correct this error?  My research is saying I need to modify the code but I would figure NXP would make code available that does build without basic code modifications.

Thank you for your help Alejandro.

Hello @duglew60 

I hope you are doing well.

Could you please try:

Download gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2 from https://developer.arm.com/downloads/-/gnu-rm

Then:

$ tar -xf gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2 
$ export ARMGCC_DIR=~/gcc-arm-none-eabi-10.3-2021.10
$ export PATH=$PATH:~/gcc-arm-none-eabi-10.3-2021.10

Go to SDK example directory (In my case):

$cd ~/SDK_2_9_0_MEK-MIMX8QX.tar/SDK_2_9_0_MEK-MIMX8QX/boards/mekmimx8qx/demo_apps/hello_world/armgcc

And please run the build_release.sh

$./build_release.sh

Please let me know how it was.

Best regards!
