strptime not declared

[JRDavisUF 5]

I'm using Rei Vilo's RTC Library: https://github.com/rei-vilo/DateTime_Library

Under Code Composer 7.4 / Energia 18 / MSP432 Red Board 4.9.1  this library compiles works fine.

When I switched to Code Composer 8.0 / Energia 18 / MSP432 Red Board 5.6.1, "strptime" seems to have disappeared.  Anyone have any ideas on what happened?

Libraries/RTC/subdir_rules.mk:9: recipe for target 'Libraries/RTC/RTC_Library.o' failed
../Libraries/RTC/RTC_Library.cpp: In function 'uint8_t convertString2DateTime(String, String, tm&)':
../Libraries/RTC/RTC_Library.cpp:88:59: error: 'strptime' was not declared in this scope
     if (strptime(charDateTime, charFormat, &_timeStructure) == NULL)
                                                           ^
thx.

What happens if you select MSP432 non red LaunchPad?

Does this Sketch compile in Energia 18? It could be a compiler issue as it is part of libc. CCS uses a later version of the GCC compiler that might need the flag -D_POSIX_SOURCE to pull in those functions. You can try editing platform.txt and add the flag like so:

compiler.c.extra_flags={compiler.emt.c.flags} {compiler.driverlib.c.flags}
becomes
compiler.c.extra_flags=-D_POSIX_SOURCE {compiler.emt.c.flags} {compiler.driverlib.c.flags}

Platform.txt is in:

On GNU/Linux: ~/.energia15/packages/energia/hardware/msp432r/5.6.1/
On Windows: %LOCALAPPDATA%\Energia15\packages\energia\hardware\msp432r\5.6.1\
On MacOS: ~/Library/Energia15/packages/energia/hardware/msp432r/5.6.1/

I tried editing the platform.txt file, but it didn't seem to do anything....that is, I could never see the -D.. appearing anywhere during the compilation process.  I did try changing my compiler settings to directly include the -D... so that I could see where it was being used, but it didn't seem to make any difference and the error I mentioned still showed up.

I did realize that the routine that uses strptime isn't used by my code, so I commented it out that whole routine and my stuff works fine...so at least for now, I can punt on this issue...thanks for trying though...
