The library .dylib file path was not found when building cairo for macOS. Now it is possible to build cairo for macOS. Built library files for cario and pixman are adjusted using the tool install_name_tool, and also solenv/bin/macosx-change-install-names.pl perl script which also uses install_name_tool indirectly. From now on, macOS no longer uses the name 'libcairo' for built library file, and it will use 'libcairo-lo' like the other platforms. This removes the need for handling macOS differently from the other platforms. To use headless mode, these options should be added to autogen.input: --enable-headless --without-system-fontconfig --without-system-freetype Change-Id: I1895ba651a07b1dbd8488fa973ec1d90c24de63b Reviewed-on: https://gerrit.libreoffice.org/c/core/+/194931 Tested-by: Jenkins Reviewed-by: Dan Williams <dcbw@libreoffice.org> Reviewed-by: Hossein <hossein@libreoffice.org>

# Including -rtlib=compiler-rt in pixman_LIBS is a BAD HACK: At least when compiling with Clang
|
|
# -fsanitize=undefined on Linux x86-64, the generated code references __muloti4, which is an
|
|
# extension provided by libclang_rt.builtins-x86_64.a runtime, but not by GCC's libgcc_s.so.1 (which
|
|
# ultimately boils down to a bug in LLVM, I would say). I am not sure whether it should in general
|
|
# work to mix uses of the (default on Linux, at least) GCC libgcc_s and LLVM's libclang_rt.builtins
|
|
# runtime libraries in one process, but for this specific case of libcairo.so it appears to work
|
|
# well: For one, the only symbol referenced by libcairo.so from the runtime library is __muloti4;
|
|
# for another, at least in my LLVM build, lib/clang/12.0.0/lib/linux/libclang_rt.builtins-x86_64.a
|
|
# is only provided as a static archive; so libcairo.so will only contain a "harmless" copy of
|
|
# __muloti4 and not have a DT_NEEDED of any libclang_rt.builtins dynamic library that it would pull
|
|
# in at runtime.
|
|
# But passing -rtlib=compiler-rt into cairo's configure via the more obvious LDFLAGS would fail at
|
|
# least when building with -fsanitize=address and -fsanitize=undefined, as then the executable
|
|
# compiled by configure when "checking whether the C compiler works" would reference
|
|
# _Unwind_Backtrace etc. that are provided by GCC's libgcc_s.so.1 but not by LLVM's
|
|
# libclang_rt.builtins-x86_64.a (and whatever the reason for that inconsistency). So
|
|
# -rtlib=compiler-rt must be passed just into the linking of libcairo.so, but not generally into
|
|
# cairo's configure. And pixman_LIBS happens to offer that. (The -Wc is necessary so that libtool
|
|
# does not throw away the -rtlib=compiler-rt which it does not understand.)
|
|
|
|
# We control how cairo handles its subprojects/dependencies by adding entries to PKG_CONFIG_PATH .
|
|
# Meson will look in those locations for *.pc files, which contains FLAGS and LIBS entries.
|
|
|
|
# We set PKG_CONFIG_TOP_BUILD_DIR= in order to work around some pkg-config weirdness, which otherwise
|
|
# will make meson crash.
