Compiling GeneralizedTime.c fails on WSL/Ubuntu

Compiling GeneralizedTime.c on WSL/Ubuntu gives me the following errors:

My time.h does not contain struct tm. Is there a way to fix it or a workaround?

Thanks,

[gaetanww]

Manually including </usr/include/time.h> in GeneralizedTime.c and UTCTime.c solved the issue as a workaround.

I am facing the same issue on windows. Do you know any workaround?

That didn't work?

[chetanpandey1266]

No it is giving no such file or directory

[chetanpandey1266]

I checked my time.h file and I couldn't find any struct tm in it. Do I have to include this file separately from somewhere??

[kentkost]

Unlikely. struct tm exists in both Cygwin, Mingw and Clang. I have no idea what compiler/environment you're using. You're probably looking in sys/time.h and not usr/include/time.h.

What compiler are you using? Are you using a development environment like msys2 or cygwin? What is the output of your terminal?

[chetanpandey1266]

I am using gcc ( mingw ). I even tried with clang but giving the same output

[chetanpandey1266]

This is the output I am getting for gcc
