|

* - NANA_LINUX

|

* External libraries:
|

* - NANA_LIBPNG, USE_LIBPNG_FROM_OS
|
||||
* - NANA_LIBJPEG, USE_LIBJPEG_FROM_OS

* (see: Feature-testing recommendations for C++
|
||||
* in http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/p0096r0.html
|
||||
* for example: __cpp_lib_experimental_filesystem = 201406 in <experimental/filesystem)
|
||||
*
|
||||
* Workaround to known compiler errors, unnecessary warnings or lack of C++11/14/17 support:
|
||||
* - _SCL_SECURE_NO_WARNNGS, _CRT_SECURE_NO_DEPRECATE (VC)
|
||||
* - STD_CODECVT_NOT_SUPPORTED (VC RC, <codecvt> is a known issue on libstdc++, it works on libc++)
|

* - STD_THREAD_NOT_SUPPORTED (GCC < 4.8.1)
|
||||
* - STD_NUMERIC_CONVERSIONS_NOT_SUPPORTED (MinGW with GCC < 4.8.1)
|
||||
* - USE_github_com_meganz_mingw_std_threads (MinGW with GCC < 4.8.1)
|

* - STD_NUMERIC_CONVERSIONS_NOT_SUPPORTED (MinGW with GCC < 4.8.1)
|

* - STD_TO_STRING_NOT_SUPPORTED (MinGW with GCC < 4.8)
|
