HI, MCUXpresso Expert


When I include <ctype.h> and call isdigit('A') function, during link stage, it report 'undefined reference to `__ctype'.

This only happens when I use connectivity example project, when uses driver example project, there is no problem. 


I had tried to change several library format, it still has the same issue.



Environment: MCUxpresso 10.1.1

SDK: QN908x GA
