Hi

The latest version produces strange failures on linkage: https://travis-ci.org/MIPT-ILab/mipt-mips/jobs/383377807. IIUC, for methods of Option class inline qualifier protects from those error , but it looks like it does not help for ...HelpPrinter classes.

I suspect the problem is these functions are virtual, but not pure-virtual in the base class. It is impossible to inline a virtual function by definition, so compiler leaves them as is, making their symbols accessible outside. Note that since templates instances are not intended to have an external linkage by default, there are no problems with classes derived from Option.

There seems to be a parsing difference between --foo bar and --foo=bar if argument is declared implicit. The former is parsed as "Use --foo but with the default value" followed by a positional argument with value bar whereas the later is parsed as expected.

Hi,

CMAKE_CXX_STANDARD does not work with older cmake versions (not sure which one, but 2.4 does not support it); therefore, it builds with C++ < 11 and fails (e.g. "nullptr").

If version is less than 3.1, CXX flags should be set explicitly:

if (CMAKE_VERSION VERSION_LESS "3.1")
    if (CMAKE_CXX_COMPILER_ID STREQUAL "GNU")
      set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=gnu++11")
    endif ()
  else ()
    set (CMAKE_CXX_STANDARD 11)
  endif ()

Hi,
I just tried the default value argument and it doesnt work.

How do I assign default value to the variable itself ?
