First, for those who don't know, something about MSVC versions (it is easy
to get confused there):
MSVC 8: Microsoft Visual Studio 2005
MSVC 9: Microsoft Visual Studio 2008
MSVC 10: Microsoft Visual Studio 2010 Don't be mislead by the nice fit!
MSVC 11: Microsoft Visual Studio 2012 From here on we are "one off"!
MSVC 12: Microsoft Visual Studio 2013
MSVC 14: Microsoft Visual Studio 2015
Peter added a workaround for mixing code compiled by MSVC 12 and MSVC 10
some time ago:
http://www.lyx.org/trac/changeset/6b4c3036/lyxgit/ According to
https://msdn.microsoft.com/en-us/library/7sf3txa8.aspx the /vd2 option is
only needed if one wants to violate the C++ standard (using dynamic_cast on
an object being constrcuted does not work in standard conforming compilers).
I'd like to get rid of this for two reasons:
1) Mixing different MSVC versions is a bad idea as explained in the other
thread, so we should not help people to shoot themselves in the foot.
2) We cannot use dynamic_cast on not fully constrcuted objects anyway, since
we support other compilers besides MSVC.
OK to go in?
Was a decision made on this? Peter seems to be around so let's see if he
has a comment. If no one else comments, I would say please commit.
Scott
I already removed the /vd2 flag when adding the download of the new 2013
dependencies.
But in meantime it shows that it is impossible to use msvc2013 or msvc2015:
http://www.lyx.org/trac/ticket/9892
So when someone wanna use msvc2012 he should enable the 3rdparty build,
-DLYX_3RDPARTY_BUILD=1 .
