"strptime" don't get compiled
Posted: Tue Nov 14, 2017 4:12 pm
Hi ESP-IDF,
today I have another issue, my toolchian can't figure out what is strptime. I've did some research on this. Some one said, it is not a standard C function, but a POSIX standard function. And my elcipse did successful found this function in <time.h>. But ESP-IDF still won't compile.
Any tipp for me?
