When using -std=c++11, the cygwin compiler automatically defines
__STRICT_ANSI__ which is used as a guard for not declaring essential
unix standard calls such as setenv, popen, etc. As a result,
compilation stops with errors such as "xxxx has not been declared".
By undefining the guard, compilation succeeds and lyx works Ok.
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.
This replaces commit 329eae56 with a better solution. Indeed, while
__cpluplus is useless with g++ 4.[3-6] because its value is always 1,
these compilers define __GXX_EXPERIMENTAL_CXX0X__ when "-std c++0x" is used.
Therefore the code now relies on both macros to detect C++11 mode
instead of setting it when --enable-cxx11 is used.
Also, use pure c++ mode instead of gnu++ extensions on gcc
This replaces tests for __cplusplus >= 201103L, which are wrong with gcc 4.6 and earlier. Indeed these versions of gcc define __cplusplus = 1.
Reference:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=1773
We claim that gcc 4.x is needed in INSTALL, so it does not make sense to keep
this old stuff. Instead, I made configure output an error if gcc is too old.
The GNU libstdc++ that ships witch gcc 5 can be used with the same ABI as
older versions, or with a new ABI which is conformant to the C++11 standard.
LyX did not build if the latter was used:
https://kojipkgs.fedoraproject.org//work/tasks/1267/9651267/build.log
This is now fixed by detecting the ABI version and disabling the wrong forward
declarations. At the same time, STD_STRING_USES_COW is switched off for the
C++11 ABI version, because the std::basic_string implementation is now C++11
conformant. Since the GNU libstdc++ can also used by other compilers such as
clang, we must not test for the compiler version.
Now CXXFLAGS is left alone by autoconf: only the user can override it.
Properly set -g and -O options, which were overriden.
Try to put the arguments in a more reasonable ordering.
Get rid of some old useless compiler checking code
Do not touch CXXFLAGS and friends, only the AM_* version
Let the gcc-related options for latest known version be the default (assume they will still be fine in future versions)
Try to take clang in account in a better way (to be continued):
* use proper option for C++11,
* use -Wno-deprecated-register in this case because Qt has a lot of these
* define version as being clang for internal testing (there is no real way to get the clang version)
The old detection did only work if CFLAGS contained -std=c++11, since ciso646
was only included for __cplusplus > 199711.
Thanks to Koernel for the cmake part.
The interface is now 100% unit tested, and the typedefs depend on the new
STD_STRING_USES_COW configuration variable. The only missing bit is to detect
clang and disable STD_STRING_USES_COW for clang.
Note that some mentions of svn remain in
* development/cmake/LyxPackaging.cmake
* development/LyX-Mac-binary-release.sh
* development/Win32/packaging/installer/settings.nsh
* 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.
Just some comments on the patch:
- The executable name has to match the information in Info.plist (development/MacOSX/Info.plist.in and CMakeLists.txt). The autoconf config/lyxinclude.m4 file has been modified to make it work with autotools.
- The process to build OS X bundle is to first add all the files to be included to the bundle when calling add_executable (src/CMakeLists.txt) and then by calling setting the source file property of each of these files (development/cmake/Install.cmake, l.14) so that the files are properly located into the bundle. This is also why Install.cmake has to be included two times in src/CMakeLists.txt (once to build the list of files, once to set the location of the list of files).
- in CMakeLists.txt there is a line
install(CODE "set(BU_CHMOD_BUNDLE_ITEMS 1)")
What it does is to fix the owner permissions within the bundle - this is necessary because some libraries are copied within the bundle and might be owned by root
- An empty qt.conf is included in the bundle so that QT does not try to link to other QT libraries (which will not be included in the bundle)
- In development/cmake/Install.cmake, some OS X specific files (*.sdef, qt.conf, *.icns) have to be included in the bundle
Benjamin
* add proper INSTALL_POSIX conditional for makefiles
* move all the code to Makefile.am
* rename lyx.desktop to lyx.desptop.in and add proper tags to allow handling of program_suffix.
* add code to install desktop entry and icons under the proper name.
I did not touch scons and cmake, I hope it was not necessary.

Only for autotools, I don't know how to update cmake and scons, sorry.
For cmake and scons, you should make sure that moc is called on Server.h
using the -D_WIN32 option.
In order to enable the server, specify the LyXServer pipe in
Tools->Preferences->Paths. The path to be entered there must have the
form "\\.\pipe\nameofyourchoice" (without quotes). After that, you can
send commands to LyX. For example, if the pipe path is \\.\pipe\lyxpipe,
typing the following in a terminal:
echo LYXCMD:test:file-open > \\.\pipe\lyxpipe.in
type \\.\pipe\lyxpipe.out
brings up the file dialog and returns the acknowledgment from LyX.
Beware of spaces when using cmd.exe. For example, the following:
echo LYXCMD:test:file-open:foo.lyx> \\.\pipe\lyxpipe.in
will correctly load the document named foo.lyx, but
echo LYXCMD:test:file-open:foo.lyx > \\.\pipe\lyxpipe.in
(notice the space before the redirection) will try to load a
document whose name is "foo.lyx .lyx" because cmd.exe will also
pass the space (sigh).

using --with-version-suffix (without value), config.status will be
written wrongly and try to run
./configure--with-qt4-lib= [...]
This is because the code that adds automatically the version number eats
the leading space.
