Missing file?

[DivFord]

I'm getting this when I make:

Scanning dependencies of target game [ 7%] Building CXX object CMakeFiles/game.dir/lib/AI.cpp.o In file included from /Users/Div/Documents/Games/Global_Game_Jam_2015/potentia/lib/AI.cpp:1: In file included from /Users/Div/Documents/Games/Global_Game_Jam_2015/potentia/lib/UnitList.hpp:5: /Users/Div/Documents/Games/Global_Game_Jam_2015/potentia/lib/Config.hpp:6:10: fatal error: 'type_traits' file not found

Has anyone else tried to build since the last push? I assume the push was Iain's, so my question is really, Iain, did you push type_traits?.

[Fyll]

Nope, that wasn't me. Seeing as I made the last push, I should be up to date, yet I have no problems compiling...

Looking at the code, type_traits looks to be a standard library, so maybe it's just not present on Mac?

[DivFord]

I've had a look. You're right. type_traits, unordered_maps and unique_ptr aren't in the std library on the mac. There might be a workaround, but it looks fiddly. Any way we can use more easily portable libraries? (I have no idea how this might play out on Windows).

[DivFord]

Apparently I'd mucked up my cmake files, and was compiling with the wrong standard libraries. Fixed now. It's getting upset about Time.hpp instead.

Okay, a few comments on this:

First of all, the old code shouldn't have worked (sleep() only has second precision, so would have been sleeping for 0s all of the time). Secondly, Macs may not have sleep(). Windows definitely doesn't. Thirdly, I've re-written it into a (hopefully) cross-platform version. I obviously can't check, but I think it's good.

It's been pushed, so have a look.

[DivFord]

Cool, all working now.
