In some cases we need to add additionl defs to build against icu if
icu has certain options configured.
ICU warns about this when building:
*** WARNING: You must set the following flags before code compiled against this ICU will function properly:
-DU_DISABLE_RENAMING=1
We can fetch these flags from the icu pkgconfig and add them if
required.
This fixes symbol errors if ICU is built without renaming.
We implicitly require it for building ragel subproject. This new version
requirement should satisfied in both Fedora 33 and Debian bullseye, and
not be too cutting edge for us.
If ragel 6.10 is not found, build it from source.
Seems to work, except that ragel uses exceptions and we configure
HarfBuzz build to not use exceptions, and I can’t find away to enable
exceptions only for the ragel subproject. I had to remove cpp_eh=none
from default options and try to disable exceptions in MSVC manually
(other compilers are already handled).
Ragel 7 is also not stable from upstream's point of view.
This uses “version” argument find_program(), which was introduced in
meson 0.52.0, so I raised the minimum required meson version
accordingly.
We don’t currently use it anywhere. It was used briefly for the
hb-fc-list tool, but this tool have not been built since 2015:

[util] Disable hb-fc-list for now
Until I figure out what to do about the API, and finalize
the tool.
It downloads a dependency from the internet, and in the same time not
used anywhere (one needs to explicitly call ninja benchmark), not even
on the CI (not sure if it that would make much sense since it does not
seem to ever fail).
When cairo comes from a subproject fallback it should still take
cairo-ft dependency, otherwise it miss freetype2 cflags.
Also update wrap file to use upstream repository now that meson support
has been merged.
This requires Meson >= 0.54.0 because cairo itself requires that version
and we use the new `fallback: 'cairo'` syntax without specifying a
variable name because cairo does not provide a variable name for
cairo-ft.
If we want to support a build with exception handling and RTTI
We should reflect that on library(..., link_language: 'c') also so for
now it is ok to just set it here to get MSVC support also and we
can remove hard coded flags later upon request.
One other concern over just relying on it is on when harfbuzz is used
as a subproject and the parent project hasn't provided the same options,
that should be resolved first I think.
Closes#2584
It was put there as current situation of autotools but msys2 is ok
with the flag, if something like is needed for other it can handled
as a local patch.
meson documentations sometimes adds the space and sometimes don't and we
aren't adding it most of the times unconsciously so let's the cases and
be consistent.
'disabled' wasn't implemented for some of the features so they were
getting found even with explicit -Dfeature=disabled, this implements it.
Run the following command to test this change and check whether 'disabled'
was actually effective,
meson build -Dglib=disabled -Dgobject=disabled -Dcairo=disabled -Dfontconfig=disabled -Dicu=disabled -Dfreetype=disabled -Dintrospection=disabled -Dgtk_doc=disabled
This is useful when one wants to integrate harfbuzz into another project via
meson's subproject mechanism.
Instead of passing dependencies as required we used one giant shared
dependency list containing all dependencies for every library/executable.
While this kinda works, the specified deps are also used for generating
the pkg-config files and this leads to lots of Requires.private and Libs.private
entries which aren't really needed.
This removes the "deps" array and replaces it with a few smaller ones and
makes sure the public libraries only get passed the dependencies actually
needed.
Fixes#2441
As a part of meson migration, this builds hb-shape dependencies
using meson subprojects and removes different unrelated mingw
files we've put on source root about things that aren't really our
concern. This also simplifies all the instructions we've put in
README.mingw.md and makes it easy to build the project on
distros that no mingw libraries (such i686-win32-{freetype,glib,...}
are packaged. The known catch is however lack of hb-view as its need
for build of cairo which apparently isn't that straightforward.
This adds a seperate library like with autotools.
This also fixes the ico feature option which was just set to required:false
when disabled instead of really disabling it.
Disabling is still broken with msvc because it then tries to find the library
another way, but that's broken for all other deps as well so I left it as is.
For tests only test-unicode.c is using icu specific functions so split it out
into its own category which depends on harfbuzz-icu.
Fixes#2338
Fixes compiler warning
test-unicode.c:589:1: warning: ‘test_unicode_properties_lenient’ defined but not used
which didn't happen with autotools.
Reason it does with meson is that the setup for C was slightly wrong.
We would only add -DHAVE_CONFIG_H to cpp_args which is only valid when
compiling C++ code, but not plain C code, and many of these tests were
plain C.
Instead pass -DHAVE_CONFIG_H via add_project_arguments() and make sure
to set both c_args and cpp_args when building test executables.
Fixes https://github.com/harfbuzz/harfbuzz/issues/2257
...and supersede the configuration option uniscribe with gdi, as Uniscribe is
tightly tied to GDI. This means that enabling GDI would also mean enabling
Uniscribe.
Since Cairo's build system for Visual Studio does not generate pkg-config files
for us, look for cairo.h and cairo.lib manually if the pkg-config files cannot
be found.
Also look for cairo-ft more carefully: ensure that we have cairo-ft.h, and one
of its symbols can be found in the same cairo.lib that we previously found.
ICU's Visual Studio build files do not generate pkg-config files for us, unless
it is built with Cygwin instead of the project files. If pkg-config files for
ICU cannot be found, look for its headers and .lib manually.
