This allows to fix distclean properly, since we know that
subdir-objects is used. When it is the case, it is not a good idea for
a Makefile to use a source file which is under the control of another
one. This could not be made to work work with old automake versions
(<1.14).
Therefore we refer directly to object files in Makefile.am instead of
source files. The actually leads to less compilation in tex2lyx.
Update the code here and there to remove compatibility hacks. Update
documentation.
Re-enable the layout test and fix the Length test, which was ovewriting
memory in test_inPixels() because lyxrc did not had a correct layout.
Only enable std::regex when the header <regex> is present (fix Mac OS X issue).
Remove support for concept checks. The page
https://gcc.gnu.org/onlinedocs/libstdc++/manual/concept_checking.html
says about concept checking:
Please note that the checks are based on the requirements in the
original C++ standard, many of which were relaxed in the C++11
standard and so valid C++11 code may be incorrectly rejected by the
concept checks. Additionally, some correct C++03 code might be
rejected by the concept checks, for example template argument types
may need to be complete when used in a template definition, rather
than at the point of instantiation. There are no plans to address
these shortcomings.
Therefore it seems reasonable to remove our support for this.
In general this would lead to an immediate runtime crash because the
runtime checks of libstdc++ change the layout of some STL objects.
Therefore, this will only work when the boost libraries have been
compiled with this same flag. At this time, it is not known whether
any linux distribution contains such libraries.
Fixes bug #9736.
Compiler that are known to support C++11 (gcc >= 4.3 and clang) are
now used in this mode by default. It is still possible to override
this choice using --(en|dis)able-cxx11.
Moreover, c++11 mode is detected from the compiler itself, not from
the use of --enable-cxx11. This allows to support compilers other
than gcc or clang.
Update INSTALL file accordingly and clean it a little bit.
The option --enable-qt5 allows configuring for Qt5. The default is Qt4.
Nothing special is done with respect to Qt4, apart from pulling in the
correct libraries. Indeed, other than the core and gui libraries, now
also the concurrent and widgets libraries are needed.
* build-type=profiling implies -fno-omit-frame-pointer in gcc. This allows sysprof to yield proper call trees
* remove --enable-grpof option (the build type is enough)
* remove --with-frontend option since we have only one frontend. Move stuff around and generally simplify the Qt detection code
* do not check for bc anymore.
* Update README.
Do not use AM_PROG_MKDIR_P, which is obsolete. We use the AC_* version
now, which requires autoconf>=2.59d. This also mean that we need to use
the variable MKDIR_P instead of mkdir_p.
