If the included thirdparty libs are requested, use them, even on unix. This is
consistent with autotools (but the recommended way is of course to use the
system libs). If the included thirdparty libs are not requested then try to find
libiconv and zlib also on windows. This will lead to an error unless the libs are
found via manually added include and link paths, but this is wanted since
libiconv and zlib are not optional.
Boost.Signals is deprecated. This fixes bug #9943.
The only thing left to do is to rewrite (or get rid of) the boost -mt test
in config/lyxinclude.m4 not to use signals anymore.
As discussed on the list. If no C++11 compiler is found configuration stops
with an error. There are now unneeded parts of boost, the will be removed in
a second commit.
For a suffixed version (with suffix 2.3) and installation dir (/usr/local)
the new paths are:
binary -> /usr/local/bin
system-lib -> /usr/local/share/lyx2.3
fonts -> /usr/local/fonts/truetype/lyx2.3
manuals -> /usr/local/man/man1
locales -> /usr/local/share/locale
tex -> /usr/local/texmf/tex/latex/lyx2.3
Nothing changes for already cached values.
With fresh build-dir and in 'AUTO'-mode we try to determine if the c++ compiler
is able to use this feature.
It works with gcc >= 4.9.0 and clang (with libc++ or gcc libstdc++ from gcc
>= 4.9.0). The MSVC parg is missing, because I cannot test it, and the
autotools build still link against boost::regex even if it is not needed, but
I don't know how to fix that.
As discussed on the list. We don't need it anymore, either we have a modern
compiler that supports C++11, or we fall back to boost. I kept and adjusted
the regex #define, since we cannot use std regex completely yet.
If we compile in C++11 mode, do not use the boost replacements for bind,
functional and shared_ptr. regex is excluded, since it misses match_partial, and
gcc does not provide a usable one in versions less than 4.9.0.
I also removed the #define for match_partial, since this is dangerous. Now you
get a compile error instead of subtle runtime differences.
