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 command "paste pdf" was always disabled because the
condition in the following "if" statement always returns false
if (arg == "pdf" && (type = Clipboard::PdfGraphicsType))
The value of "type" is zero in this case because PdfGraphicsType is
the first enum value (and it is not set explicitly to non-zero).
An alternative patch is to put AnyGraphicsType as the first
element of enum GraphicsType, or to set the first element to a
number greater than 0.
To test the bug that this commit fixes, either copy a PDF and try to
paste with the action "paste pdf", or click on the "Edit" menu and
notice (before this commit) the terminal output "Unrecognized
graphics type: pdf".
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.
This is still a hack, but a less dangerous one. The old code had a problem
if it was called from different threads, or if for some reason it would get
called recursively.
The document iterator now skips math insets and insets like notes where spell check is disabled.
The continuous spell checking is part of the row painter drawing and the spell check disabled state
has to be passed down recursively while doing the inset painting.
Some distros may use target-specific prefix for ar program (like
x86_64-pc-linux-gnu-ar). Automake can handle that since version 1.12.
Since we still support automake 1.8 (not that it is really crucial,
but ubuntu 12.04 ships with automake 1.11.3), make the code
conditional.
Update a bit the gitignore files (automake creates some files in config/).
Based on a patch from Nikolay Orlyuk <virkony@gmail.com>.
Because of our better mechanism for dealing with errors (72c5385f),
the problem described in the comment is no longer possible.
NO_OUTPUT is treated as an error so there will no longer be a
lingering PDF in this case.
