Seems you use the wrong toolchain.
Y17 ext is wrong path.

#5

Also you need to make clean and then make first befor you type make wp76xx

Hi. Nice to meet again.
The cross-compilation chain I use is “poky-swi-ext-glibc-x86_64-meta-toolchain-swi-ext-armv7a-vfp-neon-toolchain-swi-ext-1.7.3.sh”

I executed bin/legs first, then executed make, but there is still an error.
make[2]: Entering directory ‘/home/fhs/workspace/legato/build/localhost’
make[2]: *** No rule to make target ‘user_docs’。 停止。

HI.

I changed the environment variable to the following and it succeeded! I tried this yesterday, but I didn’t succeed, so amazing. Thank you for your reminder

export WP76XX_TOOLCHAIN_DIR=/opt/swi/y17-ext/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi
export WP76XX_TOOLCHAIN_PREFIX=arm-poky-linux-gnueabi-

I just facing the same issue.
My solution is installing cmake on my host building machine.
