Strptime Undefined Reference Error about datetime-fortran HOT 7 CLOSED

Hi Doug,

Not sure what's going on here. I can compile and link the example without issues on my system (Ubuntu).

This is a linker error so your compile step works. It seems like you have a libdatetime.a (otherwise the linker would complain about it) but it can't find the strptime method in there. Just for a sanity check, what is the output of nm libdatetime.a | grep __mod_datetime_MOD_strptime for you? You should get something like 0000000000000346 T __mod_datetime_MOD_strptime is libdatetime.a was created correctly.

Unfortunately I have zero experience with MinGW, so I don't know if this could be related to it.

Hey, thanks for the quick reply. Running the sanity command check you mentioned gives:

0000000000002290 T __mod_datetime_MOD_strptime

I think the issue is related to using WSL to build / compile datetime-fortran, but then switching back over to using MinGW to link the library to my project. Unfortunately we're using MinGW and Windows across the project.

Hi,
is there an easy solution to get datetime-fortran working using mingw in windows ?
thanks

Hi @VinniDoddu,

Unfortunately, I haven't learned anything new since the start of this issue, and still have zero experience with MinGW. From reviewing the issue again, my suspicion is that on MinGW the linker is not able to find strptime. This should be in the C standard library inside time.h. I don't know if on MinGW this function is not provided, or perhaps defined in some other place that is not in default include and link path.

@scivision just added a fix for this which is now in master.

@dcdenu4 @VinniDoddu Can you try it and see if it works?

Closing. If the issue persists, please reopen.

Hey, sorry I missed this. I'm no longer on the project that pertained to this issue and don't have access to the codebase... Thanks for the work and reaching out!
