5955 # Mono.Native Support
5956 # -------------------
5957 # Mono.Native is the new name for both System.Native and System.Security.Cryptography.Apple.
5958 # It is built as a stand-alone shared library and not bundled with the runtime because we
5959 # may need to build two different versions of it.
5961 # Starting with macOS 10.12+ and iOS 10+, Apple introduced a new Unified API for some of the
5962 # crypto primitives that we're using as part of System.Security.Cryptography.Apple.
5964 # On Desktop, we can check at runtime whether the OS version is recent enough and switch
5965 # implementation accordingly.  We build a single `libmono-native` shared library.
5967 # However, on Mobile we cannot have any undefined symbols as this would break Bitcode.
5969 # During the mobile build, we are called with `CFLAGS` containing an explicit minium version flag,
5970 # which is eiter `-mmacosx-version-min=`, `-mios-simulator-version-min=` or `-miphoneos-version-min=`
5971 # depending on platform.
5973 # We build two versions of the shared library:
5974 # - `libmono-native-compat` is built with whichever minimum version is passed to us via `CFLAGS`.
5975 # - `libmono-native-unifed` is built with the minimum version set to macOS 10.12+ / iOS 10+.
5977 # For testing purpuses, there is a function called `mono_native_get_platform_type ()`
5978 # (see mono/native/mono-native-platform.c), which returns a `MonoNativePlatformType` enum value.
5979 # There is also `Mono.MonoNativePlatform.GetPlatformType ()` (see mcs/class/corlib/Test/Mono/MonoNativePlatform.cs).
5981 # This can be called by automated tests both to ensure that the library has been correctly installed and also
5982 # to verify that it's the correct version of it.

6220 # We have to lie to autotools, sometimes.
6222 # If we're building with llvm compiled into Mono, set MONO_CXXLD to CXX,
6223 # otherwise to CC.  We want C linking even if we're compiling with C++ enabled
6224 # because we do not want to link inthe C++ runtime library (-lstdc++ or -lc++),
6225 # except if we're linking with LLVM which relies on it.
6227 # Explanation of the hack:
6229 # According to
6230 # https://www.gnu.org/software/automake/manual/html_node/How-the-Linker-is-Chosen.html,
6231 # automake chooses the linker that it used to compile a target based on the
6232 # _SOURCES for that target.  If the target is comprised of only C code, it
6233 # chooses the C linker (on Linux and OSX this is just gcc or clang called with
6234 # linker arguments and a -o).  If the target _SOURCES include at least one C++ file, 
6235 # then automake chooses the C++ linker (usually g++ or clang++ called with linker arguments and -o).
6237 # The problem for Mono is that we don't want the C++ runtime library (libstdc++
6238 # or libc++) linked in - even when Mono is written in C++, we take care not to
6239 # require the runtime library.  As a result, we don't want g++ or clang++ to do
6240 # the linking.  On the other hand if LLVM is enabled, then we _must_ use the
6241 # C++ linker - LLVM doesn't have the same restrictions.
6243 # So the trick is we set MONO_CXXLD here to $CXX or $CC and in
6244 #  mono/mini/Makefile.am.in we have CCLD=$MONO_CXXLD and CXXLD=$MONO_CXXLD which bypasses
6245 #  automake's autodetection and lets us use the linker that we want.
