Seems you are still using y17-ext toolchain.
Can you double check $PATH and see if /opt/swi/y17-ext/sysroots/armv7a-neon-poky-linux-gnueabi/ still there? Or try to change the name of y17-ext.

Hi,
there is similar issue here:
> [@Issue in Installing AF 17.11.0 on Ubuntu](https://forum.legato.io/t/issue-in-installing-af-17-11-0-on-ubuntu/2986/2):

> Hi, Did you download the toolchain from here for WP76xx: [https://source.sierrawireless.com/resources/airprime/software/wp76xx/wp76xx-firmware-release-7-components/](https://source.sierrawireless.com/resources/airprime/software/wp76xx/wp76xx-firmware-release-7-components/) If no, please try this.
Please use the correct toolchain.

I have made some progress:
export LEGATO\_ROOT=~/legato/workspace/legato/
export PATH=/opt/swi/y22-ext-wp76xx/sysroots/armv7a-neon-poky-linux-gnueabi/:$PATH
~/mangOH(master)$ make green\_wp76xx
now compile progress, failing on:

For the missing i2c-dev-user.h, you can have a look here:
> [@WP76XX SDK 18.1.0 Missing linux/i2c-dev-user.h](https://forum.legato.io/t/wp76xx-sdk-18-1-0-missing-linux-i2c-dev-user-h/3185/5):

> There are a few different issues in play here. For some reason, the upstream i2c-tools package overwrites the include/linux/i2c-dev.h with its own version which adds some header only functions for smbus. I’m not sure why they didn’t just create a separate header called i2c-dev-smbus.h or something, but they didn’t. Yocto (or openembedded?) does something sort of non-standard in that they don’t overwrite the default i2c-dev.h file provided by the Linux kernel. Instead they rename the one from…
probably you can get those files in the toolchain.
