This new feature isn't appropriate for a minor cairo release,
(we're between 1.4.2 and 1.4.4 right now), but will make a
lot of sense during 1.5.
The code being reverted here was originally added with the
following commit:
46eab95698
but this change reverts only the public-facing parts of it.
Whilst not being able to delete all of the test output is messy it is
however not fatal, so do not abort configuration simply because we
cannot find either program.
Replace hard-coded find, xargs and rm with the paths determined during
configure. This also gives us an opportunity to detect missing programs
and inform the developer.
By defining cairo_public_warn as an extension of cairo_public, the
programmer need only to override cairo_public in order to export the
complete API for different architectures i.e. existing configurations
will continue to work with no alterations.
The attribute was introduced with gcc-3.4, but the ability to suppress
warnings from misapplied attributes (-Wno-attributes) was only introduced
later. Without the supression, gcc will emit tens of warnings for each
compilation completely drowning the real errors that the programmer
must see.
This adds a compiler check that the function result is used by the caller
and enables it by default for all cairo_private functions and for public
API that returns a cairo_status_t.
It has been discussed that to extend the warnings to all functions, a
new function type could been introduced to cover static functions:
cairo_static. This has not been done at the present time in order to
minimise the churn and focus on the more common errors.
In order to reduce the warning spew generated by gcc for invalid use of
this attribute, -Wno-attributes is added to CFLAGS. This has the
unfortunate side-effect of masking future warnings for all attributes -
be warned!
cairo-perf and the X server should be bound to CPUs (either the same
or separate) on SMP systems. Not doing so causes random results when
the X server is moved to or from cairo-perf's CPU during the
benchmarks.
Quite some time ago we switched from using deflate-based compression to LZW
for the ps backend, (which allows it to target PostScript Level 2 instead of
PostScript Level 3). Now, we finally drop the fact that the ps backend was
still requiring zlib in order to build.
Maintainer-mode is known broken behavior and discouraged. It has
created headaches before when you run configure and all in a sudden
editing Makefile.am's does not trigger a Makefile update...
Recent changes have made quartz and atsui interdependent. It is also
no longer possible to build quartz with xlib enabled due to a redefinition
of the 'Picture' symbol. This change makes '--enable-atsui' unnecessary
and refuses to switch on quartz when it cannot be built because xlib
is enabled.
We now test for windows.h availability to automatically enable win32
backends. This nicely enables compiling cairo against libwine by just
setting CC=winegcc LD=winegcc during configure. This currently only
generates static libs though.
If PKG_CHECK_MODULES fails, it does not print out any check results and so, no
newlines. This is kinda silly, at least in the case that no second branch is
provided, but I think that's the way it is, to let users decide what to print.
We now just do a AC_MSG_RESULT(no) and continue with what we used to do.
Inspired by Tor Lillqvist's similar change in Pango.
