Build Failing on Windows (x64, Windows 10, VS 2015) about haywire HOT 18 CLOSED

It looks like the hello world source set doesn't include opt.c. I don't
have access to any Windows machines to confirm though.

I got it compiled by including opt.c in the visual studio project, however when I run the program and fire off a request, it immediately exits. See the attached gif.

If you compile in debug mode, do you get an error message when you run it?

from haywire.

Nope ... nothing. The same thing happens if I try to connect via the
browser. The server ends immediately.

I wonder what
https://github.com/kellabyte/Haywire/blob/master/src/haywire/http_server.c#L203
is
actually returning in that case. Could you print the result of that call?

I set up the debugger in Visual Studio and it breaks here (strlen.asm)

Here is where the error occurs ... getting the strlen(current_time)

Sorry ... here's the screenshot

from haywire.

Humm, that's weird. I just checked the documentation on MSDN and ctime is supposed to return a null terminated string, so strlen shouldn't have an issue.

Note that current_datetime.length is initialized until the next line runs. Does strlen cause a segmentation fault or does it return?

from haywire.

It causes a segmentation fault and the program exits

And what's the value of current_time btw? I wonder if that is returning NULL.

If you need a Windows Environment to test on ... just load up this Hands On Lab from Microsoft and it gives you a full blown remote Windows - Visual Studio 2015 environment all avilable from a web browser

Sweet!

from haywire.

@mikeptweet - I ran build.bat to generate the solution files and I didn't have to add any additional sources. After that I was able to reproduce the error. I fixed it by adding:

#include <time.h>

at the top of http_response_cache.c.

Can you try doing that and running again just to confirm?

from haywire.

Opened #77 to fix it. Without the header, the current time is returns as negative and that causes ctime to return an invalid string.

from haywire.

Bingo ... thanks a bunch :-)

from haywire.

Happy to help :-)
