[mpsit] Eroare de compilare

[Catalin Vasile]

In fisierul ala se tot fac cast-uri de la un tip de pointer la altul.
In mod obisnuit astfel de erori nu apar, dar daca ai un flag activat la
compilator...

Daca este un modul deja existent in yocto pe care nu l-ai modificat, s-ar
putea ca cineva care a modificat un layer mai de baza, sa fi adaugat
flag-ul care iti genereaza tie eroarea, dar sa nu fi testat cap coada alte
module.
Anyway, ca un hint, ca se vezi ce flag-uri sunt folosite la compilare
pentru acel modul:
bitbake -c devshell nume_modul

O sa ti se deschida un terminal cu tot mediul setat pentru acea reteta.
Poti da:
echo $CC
echo $CFLAGS

si orice alta variabila de interes[1].
