A function that returns a vector<string> will lead to a crash if the
main code and the library have not been compiled with the same
stdlib-debug state. See for example:
https://stackoverflow.com/questions/4764048/stl-and-release-debug-library-mess
This is fixed by introducing a new variable STDLIB_DEBUG that contains
the flags that trigger the debug mode (autoconf only for now).
This will allow to go forward with bug #10547.
As of enchant 2.x, it is required to create a Broker instance instead
of relying on a static one provided by the library.
Add autoconf and cmake (courtesy of Kornel) tests that check whether
one can indeed instantiate a Broker object, and act on the result in a
new broker() helper function.
Fixes bug #10986.
Traditionally LyX behaves differently when the directive DEVEL_VERSION
is defined at compile time. This covers
* more detailed description of current position in status bar
* the help files are open in read/write mode
* more detailed debug output in the View Source panel
This patch introduces the new function devel-mode-toggle that allows
to use devel mode in stable releases, and vice versa.
The information is saved in the session file. The default is to
disable devel mode.
Remove all traces of DEVEL_VERSION in autoconf and cmake
Now configure searches in this order
1. system-installed library
2. code bundled with LyX
If --with-included-mythes or if no mythes library is installed, then
the script selects the bundled version. There should be no cases
leading to error message.
Use the bundled mythes by default again, since the current situaiton
create an error for anybody who does not have the system one
installed.
This is a stop gap measure and I'll return to it later (in a hurry now).
The configure code suggests that the default for
--with-included-(iconv|zlib|hunspell) is "yes", which is wrong: by
default is indeed to use the system libraries.
Change the MyThes detection to use the system version by default.
Also add to the verison information a line which lists the bundled libraries.
They moved the QT_QPA_DEFAULT_PLATFORM_NAME definition to the newly
introduced qtgui-config.h header.
This fix is also necessary for cmake, but I don't know how to do it.
It would be simply a matter of using QtGui/qtgui-config.h instead
of QtCore/qconfig.h, if QtGui/qtgui-config.h exists.
The full path of the tools is retained only if the Qt directory is
specified using --with-qt-dir. Now, when qtchooser was detected it
was blindly assumed that the corresponding system tools were being
used. These tools discriminate between Qt4 and Qt5 through the
option -qt=qt4 or -qt=qt5. However, the original Qt tools don't
understand these options, so that if they come first in the PATH,
configuration fails. So, only use those options if we are reasonably
sure that the system Qt is wanted. This is achieved by comparing the
paths of qtchooser and tools as, typically, they are located in the
same directory. In this way, if one prepends the bin directory of a
custom Qt build to PATH (and accordingly adjusts PKG_CONFIG_PATH),
configuration succeeds even if --with-qt-dir is not specified.
With both Qt4 and Qt5, when using a click-to-focus policy, the first
attempt to paste a selection by middle mouse in an external application
which has no focus may fail. It is not clear why this succeeds for some
applications and fails for others, but refreshing the timestamp of the
selection request cures the issue. The cmake part is by Kornel.
See also this thread:
http://thread.gmane.org/gmane.editors.lyx.devel/162491
If the Qt directory is specified by --with-qt-dir, the full path
of the tools is retained. Otherwise, if qtchooser is detected,
the generic names are attempted with proper arguments to select
the desired Qt version. Otherwise, the generic names with and without
proper suffixes (either -qt5 or -qt4) are checked in the PATH.
This means that --with-qt-dir=qtdir should be used only if the tools
are not in the PATH, or qtdir/bin/{moc,rcc,uic} are the right versions
for the desired Qt. In any case, it is later checked that the selected
tools are the right ones and a warning is issued if there is a mismatch.
The test is stolen from cmake code.
Tested on:
* ubuntu 12.04 with g++ 4.6, clang 3.3 (with libstdc++)
* ubuntu 16.04 with g++ 5.3, clang 3.7 (with libstdc++) and clang 3.7
(with libc++)
The last combination fails, but it seems to be related to real bugs
(reported for debian), so this is OK.
The test file is stolen from cmake. The options tested are, from the
most desirable to the least desirable:
-std=c++14 -std=c++11 "" -std=c++0x -std=gnu++14 -std=gnu++11 -std=gnu++0x
It is expected that the result will not be correct for cygwin, but
this is fixable.
With this change, it is now possible to configure with --enable-qt5
and have make use "moc -qt=qt5" automatically.
This is done when the command qtchooser is available nd the desired Qt
version (qt4/qt5) is available.
This means that it is now possible to have qt4 and qt5 builds easily
on a same linux system.
The version is read by checking the macros __clang_major__,
__clang_minor__ and __clang_patchlevel__. Hopefully they will have
coherent values everywhere.
For now, the version is used to set warnings a bit more reasonably for
older clang versions, which do not support -Wdeprecated-register and
some others that are used in pragmas in boost.
This removes many warnings when compiling with clang 3.3.
We only link against boost libraries if we do not use std::regex.
Therefore, we do not need to test how to link against boost libs unconditionally.
Also, the warning regarding stdlib-debug is only needed if we link against boost.
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.
The standard host triplet for mingw tools is is something like
x86_64-w64-mingw32 on debian and something like x86-64-w64-mingw32.shared for
mxe (http://mxe.cc). Detect windows packaging correctly for these build types.
The included hunspell should not be used on Linux or OS X, but (depending on
local configuration) it might be needed for crosscompiling a mingw target
from Linux. Now the user can choose whether to use the included hunspell or not.
cmake does already support that.
Now the only other dependency you need to cross-compile for mingw on debian
or ubuntu is qt.
The included iconv should not be used on Linux or OS X, but (depending on
local configuration) it might be needed for crosscompiling a mingw target
from Linux. Now the user can choose whether to use the included iconv or not.
cmake does already support that.
eilseq.m4 was taken from the original libiconv 1.14 package.
See bug 10053 for details. Without this, the package is only set correctly
for 32bit mingw.
Thanks Enrico for suggesting this fix and Shankar Giri Venkita Giri for
testing it.
The included zlib should not be used on Linux or OS X, but (depending on
local configuration) it might be needed for crosscompiling a mingw target
from Linux. Now the user can choose whether to use the included zlib or not.
cmake does already support that.
zconf.h.in was taken from the original zlib 1.2.8 package. The generation of
zconf.h was made equivalent to the one generated by cmake.
Since at least gcc 4.6 requires it, -std=c++11 has been passed to CPPFLAGS at 39717adfd. This was deemed necessary so that tests that use the preprocessor directly (AC_CHECK_HEADER) can have the right information.
It turns out that CPPFLAGS gets passed to objc compilation too (on Mac OS X) and this create compile-time errors.
Therefore we remove the -std flag from CPPFLAGS and re-add it to a separate variable cxx11_flags that is passed to LYX_CXX_USE_REGEX.
