Hi all :
I have been trying to bring-up the STM32MP157C and following the wiki here : ODYSSEY STM32MP157C - Seeed Wiki
In the section Network settings we have section for wifi.
When I try to execute following command:
make all_stm32mp1 CUSTOM_MOD_FILTER_OUT="jtsn-wm8960"
I get following error:
debian@npi:/usr/local/seeed-linux-dtverlays$ sudo make all_stm32mp1 CUSTOM_MOD_FILTER_OUT="jtsn-wm8960" DTC overlays/stm32mp1/stm32mp1-seeed-spi5-overlay.dtbo /bin/sh: 1: cpp: not found make[1]: *** [Makefile:213: overlays/stm32mp1/stm32mp1-seeed-spi5-overlay.dtbo] Error 127 make: *** [Makefile:156: all_stm32mp1] Error 2 debian@npi:/usr/local/seeed-linux-dtverlays$
Is this case of missing file or I am not doing something correctly? I have followed the guide exactly.

i dont know id you already solved it but you need to install the DTC compiler first :
sudo apt-get install device-tree-compiler
