On Windows 10 using Visual Studio Code. Called from the Pico Developer Command Prompt with >code
I am using C SDK - not mPython
I am trying to build the WiFi Scan example on a PICO W
( The sample as given fails not finding nmake on the CmakeLists.txt project () line - any one know why?)
I copied the example to a new folder. Using my working Blink as a template then Copy and pasted the example contents of CMakeLists.txt and picow_wifi_scan.c. I copied lwipopts_examples_common.h to the project folder.
On Build I get the following errors:

It makes getting started on the PICO W really hard going.Any advice would be welcomed.TedStatistics: Posted by tfcroft4 — Thu Feb 01, 2024 6:39 pm
