Portable Issues

Hi Macro

Since this library will be used in all the platforms with different compilers (gcc412 gcc421 gcc447 gcc482, MSVC10 MSVC11, Clang6/7), some of them actually don't suppot C++11 (< gcc482), and the Multiverse library and plugin still requires them, so is that possible to remove the all dependencies for C++11 ? Thanks !

Yes Marco this is very important.

[panta]

yes sure, in the worst case we can keep a separate branch for C++11, but I've payed attention not to use any C++11 feature, so no problem.

[pberto]

For the future C++11 will be needed, so keep it in a branch.

[zhoub]

Also, the std::array std::unordered_map were not supported in GCC412. Please try to remove this because it prevents us building on Linux & MacOSX.

[zhoub]

I will would like to make a boost branch for this. In future we just have 2 cases

• Old compiler + Boost
• New compiler + std

[zhoub]

Also, I think we should not use long, because it's 4 bytes on Win64 but 8 on POSIX.

Macro, please check my two commits, I think we should keep things easier.

@panta Marco did you see this?

[panta]

the commits seem perfect. I'll add the relevant boost detection to the CMakeLists.txt to make it available in the stand-alone version also.
I'll also fix the "long" issue.
Cheers!
