5919 # Mono.Native Support
5920 # -------------------
5921 # Mono.Native is the new name for both System.Native and System.Security.Cryptography.Apple.
5922 # It is built as a stand-alone shared library and not bundled with the runtime because we
5923 # may need to build two different versions of it.
5924 #
5925 # Starting with macOS 10.12+ and iOS 10+, Apple introduced a new Unified API for some of the
5926 # crypto primitives that we're using as part of System.Security.Cryptography.Apple.
5927 #
5928 # On Desktop, we can check at runtime whether the OS version is recent enough and switch
5929 # implementation accordingly. We build a single `libmono_native` shared library.
5930 #
5931 # However, on Mobile we cannot have any undefined symbols as this would break Bitcode.
5932 #
5933 # During the mobile build, we are called with `CC` containing an explicit minium version flag,
5934 # which is eiter `-mmacosx-version-min=`, `-mios-simulator-version-min=` or `-miphoneos-version-min=`
5935 # depending on platform.
5936 #
5937 # We build two versions of the shared library:
5938 # - `libmono_native_compat` is built with whichever minimum version is passed to us via `CC`.
5939 # - `libmono_native_unifed` is built with the minimum version set to macOS 10.12+ / iOS 10+.
5940 #
5941 # For testing purpuses, there is a function called `mono_native_get_platform_type ()`
5942 # (see mono/native/mono-native-platform.c), which returns a `MonoNativePlatformType` enum value.
5943 # There is also `Mono.MonoNativePlatform.GetPlatformType ()` (see mcs/class/System/Mono/MonoNativePlatform.cs).
5944 #
5945 # This can be called by automated tests both to ensure that the library has been correctly installed and also
5946 # to verify that it's the correct version of it.

6174 ### C++ Linker selection
6175 #
6176 # We have to lie to autotools, sometimes.
6177 #
6178 # If we're building with llvm compiled into Mono, set MONO_CXXLD to CXX,
6179 # otherwise to CC. We want C linking even if we're compiling with C++ enabled
6180 # because we do not want to link inthe C++ runtime library (-lstdc++ or -lc++),
6181 # except if we're linking with LLVM which relies on it.
6182 #
6183 # Explanation of the hack:
6184 #
6185 # According to
6186 # https://www.gnu.org/software/automake/manual/html_node/How-the-Linker-is-Chosen.html,
6187 # automake chooses the linker that it used to compile a target based on the
6188 # _SOURCES for that target. If the target is comprised of only C code, it
6189 # chooses the C linker (on Linux and OSX this is just gcc or clang called with
6190 # linker arguments and a -o). If the target _SOURCES include at least one C++ file,
6191 # then automake chooses the C++ linker (usually g++ or clang++ called with linker arguments and -o).
6192 #
6193 # The problem for Mono is that we don't want the C++ runtime library (libstdc++
6194 # or libc++) linked in - even when Mono is written in C++, we take care not to
6195 # require the runtime library. As a result, we don't want g++ or clang++ to do
6196 # the linking. On the other hand if LLVM is enabled, then we _must_ use the
6197 # C++ linker - LLVM doesn't have the same restrictions.
6198 #
6199 # So the trick is we set MONO_CXXLD here to $CXX or $CC and in
6200 # mono/mini/Makefile.am.in we have CCLD=$MONO_CXXLD and CXXLD=$MONO_CXXLD which bypasses
6201 # automake's autodetection and lets us use the linker that we want.
6202 #
