Hello,
I'm introducing in my CC3200 board an external RTC that save the date in struct tm format, my code use time_t timestamp.
To convert the timestamp and update the RTC I use gmtime() and it (seems) to work good.
For convert the struct tm retieved from RTC I need to use mktime() but when I use this function the linker block on theese errors:
- undefined reference to `_write'
- undefined reference to `_close'
- undefined reference to `_lseek'
- undefined reference to `_read'
I use gcc compiler with arm-none-eabi toolchain
Need I to include some headers relative to the platform?
Regards,
Rosario
