Mingw build

[mintyc]

Using 4.9.1 mingw64 and building examples

1. make all in examples dir doesn't find 'makefile'. Recapitalise to 'Makefile' and all OK

2. details/os.h uses GetDynamicTimeZoneInfo from windows.h
   mingw defaults to _WIN32_WINNT=0x502 (XP) so doesn't find this newer api

a) Adjust Makefile to add -D_WIN32_WINNT=0x600 or
b) add logic into os.h to cater for this or adapt to XP targets by using a different API

3. Same function in os.h reports unused variable warning for tm

inline int utc_minutes_offset(const std::tm& tm = localtime())
{

ifdef _WIN32

(void)tm;   // avoid unused param warning

I didn't manage to compile at all using mingw (64 bits, g++4.9.1 nuwen.net distribution) It give lots of errors.
Any hint on how to solve this?

[mintyc]

I didn't find STL's packaged version too useful, can't remember exactly why
but it was missing some things I needed [ threading support, I think...]

There are a range of builds here:
http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/

I use
http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/4.9.1/threads-posix/seh/

This worked out of the box with the mods I suggested

Note I see he's just added 4.9.2 builds there this week....

Paul

[mintyc]

Just tested with the new 4.9.2 release - looking good!

http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/4.9.2/threads-posix/seh/
Mingw64 4.9.2 posix - seh install - unzip to wherever
Add it's bin dir to the path
(in mingw64/bin dir you may want a link or copy of mingw32-make.exe to make.exe for convenience)

From latest spdlog git (has a couple of the fixes above already included)

In examples dir
Added -D_WIN32_WINNT=0x600 to end of CXXFLAGS (should probably add in a #ifdef WIN32)

make all
Builds example.exe and bench.exe - both run successfully

[gabime]

Great. So I assume the only thing left before declaring that mingw is supported is to create a new "Makefile.mingw" in example and bench dirs where the -D_WIN32_WINNT flag is set to 0x600..

[mintyc]

The alternative, to allow building from or targeting of Win XP for visual studio users as well, would be to rework the timezone offset in os.h to use something supported way back when. - I don't know windows APIs so can't help with that.

I know a lot of projects where even when dev-ing from more modern machines, they must still target XP and above - hence the furore when Microsoft was late in rolling out an XP targeting pack for newer visual studio release (2012).

Personally I'd just stick with your suggestion as supporting very old configurations is difficult at the best of times, besides, my work XP machine is (finally) being upgraded to Win 7 next week :)

[gabime]

Added Mafile.mingw in example with -D_WIN32_WINNT=0x600

[zaxthealien]

Tried to compile the examples with provided makefile.mingw, the one with -D_WIN32_WINNT=0x600 and didn't manage to compile it too.
the DYNAMIC_TIME_ZONE_INFORMATION was still not declared.
I used tdm-gcc 4.9.2 from http://tdm-gcc.tdragon.net/
it compiles finely with vs2013 and linux gcc on ubuntu though.
any idea why?

I am not sure. If you manage to fix it, please inform how

[mintyc]

I did originally submit a fix for this, but I don't think mingw is
currently supported as some of the fixes were subsequently reverted :(

They were a bit clunky (e.g. separate makefile) but I do think it is an
important platform to support.

-D_WIN32_WINNT=0x600 and didn't manage to compile it too.
the DYNAMIC_TIME_ZONE_INFORMATION was still not declared.
I used tdm-gcc 4.9.2 from http://tdm-gcc.tdragon.net/
any idea why?

I tested with mingw 4.9.x 64 bits and it worked fine..
@mintyc if you have makefile that fixes the problem under tdm, please send it to me or do pull

[zaxthealien]

I used 32bit version before.
Tried tdm-gcc 64bit 4.9.2, still failed.
I'll try mingw64 build. maybe it's just tdm's mingw build issue

[zaxthealien]

nope. still got the same error.

[fourier]

The compilation issue with tdm-gcc 4.9.2 and localtime_s related errors could be avoided by adding
-DMINGW_HAS_SECURE_API=1
to the defines while compiling your project and spdlog.
