Isn't LYX_ENABLE_CXX11=ON the default for clang?
By default it is OFF for any compiler.
I have to use —-disable-cxx11 with auto tools.
Why is it working with cmake for you?
Where is your Qt5 framework?
What compiler are you using?
Kornel, it would be nice to enable C++11 by default when possible in
2.2. In 2.3 we will make it a requirement. This probably means that we
have to find out how to do that with msvc and make sure that it works.
For reference the algorithm used by autotools for 2.2 is the following:
* enable c++11 by default for gcc >= 4.3 and all real clang (not the
older gcc based one)
For clang, also use -Wno-deprecated-register (lots of warnings with Qt4)
* when forcing c++11 on gcc <= 4.2, error out.
* if using gcc under cygwin use mode gnu++11 instead of c++11
Separately, detect that c++11 is enabled by testing for
__cplusplus >= 201103L || defined(__GXX_EXPERIMENTAL_CXX0X__)
We do the test separately so that people can use a compiler we do not
handle and set it manually in c++11 mode.
When c++11 mode is detected
* define LYX_USE_CXX11
* add flag -Wno-deprecated-declarations, so that we do not get warnings
about the deprecated auto_ptr (we will remove this in 2.3)
* define LYX_USE_STD_REGEX when using C++11 with either clang or gcc >=
4.9. [although there is something fishy with the current code that I
have to double check].
It would be nice if we could converge to the same algorithm in the two
build systems. If you disagree on what autotools do, we can discuss
adaptations.
