Except for the pixman include, the ANDROID cairo external is the same then the other OS use. It also builds fontconfig, so there is really no need to depend on the source (ok, this way it can be a bit more parallel, if nothing is generated). But the build nevertheless always sets includes for fontconfig anyway. And the code implied you can build Android without --disable-dynloading.

# 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.)
|
|
|
|
# overwrite src/cairo-version.h because that is just a dummy file and included
|
|
# from cairo.h in non-overridable way
