5937 # Mono.Native Support
5938 # -------------------
5939 # Mono.Native is the new name for both System.Native and System.Security.Cryptography.Apple.
5940 # It is built as a stand-alone shared library and not bundled with the runtime because we
5941 # may need to build two different versions of it.
5942 #
5943 # Starting with macOS 10.12+ and iOS 10+, Apple introduced a new Unified API for some of the
5944 # crypto primitives that we're using as part of System.Security.Cryptography.Apple.
5945 #
5946 # On Desktop, we can check at runtime whether the OS version is recent enough and switch
5947 # implementation accordingly. We build a single `libmono_native` shared library.
5948 #
5949 # However, on Mobile we cannot have any undefined symbols as this would break Bitcode.
5950 #
5951 # During the mobile build, we are called with `CC` containing an explicit minium version flag,
5952 # which is eiter `-mmacosx-version-min=`, `-mios-simulator-version-min=` or `-miphoneos-version-min=`
5953 # depending on platform.
5954 #
5955 # We build two versions of the shared library:
5956 # - `libmono_native_compat` is built with whichever minimum version is passed to us via `CC`.
5957 # - `libmono_native_unifed` is built with the minimum version set to macOS 10.12+ / iOS 10+.
5958 #
5959 # For testing purpuses, there is a function called `mono_native_get_platform_type ()`
5960 # (see mono/native/mono-native-platform.c), which returns a `MonoNativePlatformType` enum value.
5961 # There is also `Mono.MonoNativePlatform.GetPlatformType ()` (see mcs/class/System/Mono/MonoNativePlatform.cs).
5962 #
5963 # This can be called by automated tests both to ensure that the library has been correctly installed and also
5964 # to verify that it's the correct version of it.

6192 ### C++ Linker selection
6193 #
6194 # We have to lie to autotools, sometimes.
6195 #
6196 # If we're building with llvm compiled into Mono, set MONO_CXXLD to CXX,
6197 # otherwise to CC. We want C linking even if we're compiling with C++ enabled
6198 # because we do not want to link inthe C++ runtime library (-lstdc++ or -lc++),
6199 # except if we're linking with LLVM which relies on it.
6200 #
6201 # Explanation of the hack:
6202 #
6203 # According to
6204 # https://www.gnu.org/software/automake/manual/html_node/How-the-Linker-is-Chosen.html,
6205 # automake chooses the linker that it used to compile a target based on the
6206 # _SOURCES for that target. If the target is comprised of only C code, it
6207 # chooses the C linker (on Linux and OSX this is just gcc or clang called with
6208 # linker arguments and a -o). If the target _SOURCES include at least one C++ file,
6209 # then automake chooses the C++ linker (usually g++ or clang++ called with linker arguments and -o).
6210 #
6211 # The problem for Mono is that we don't want the C++ runtime library (libstdc++
6212 # or libc++) linked in - even when Mono is written in C++, we take care not to
6213 # require the runtime library. As a result, we don't want g++ or clang++ to do
6214 # the linking. On the other hand if LLVM is enabled, then we _must_ use the
6215 # C++ linker - LLVM doesn't have the same restrictions.
6216 #
6217 # So the trick is we set MONO_CXXLD here to $CXX or $CC and in
6218 # mono/mini/Makefile.am.in we have CCLD=$MONO_CXXLD and CXXLD=$MONO_CXXLD which bypasses
6219 # automake's autodetection and lets us use the linker that we want.
6220 #
