Hallo,
ich versuche mich gerade an einem esp32.
Die Toolchain und alles habe ich installiert und die examples werden
auch gebaut.
Jetzt wollte ich mal selber testen indem ich durch die Informationen von
der Dokumentation mich mit meinem WiFi verbinden kann.
https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/wifi.html#esp32-wi-fi-station-general-scenario
Dazu versuche ich zunächst die Initialisierung, aber hier scheitert es
schon am bauen.

Die einzigen errors die ich hier sehe sind
undefined reference to `esp_wifi_internal_reg_netstack_buf_cb'
undefined reference to `esp_wifi_skip_supp_pmkcaching'
was sind das für Funktionen? Diese sind nicht von mir. Muss ich damit
was machen?
