6266 # Mono.Native Support
6267 # -------------------
6268 # Mono.Native is the new name for both System.Native and System.Security.Cryptography.Apple.
6269 # It is built as a stand-alone shared library and not bundled with the runtime because we
6270 # may need to build two different versions of it.
6271 #
6272 # Starting with macOS 10.12+ and iOS 10+, Apple introduced a new Unified API for some of the
6273 # crypto primitives that we're using as part of System.Security.Cryptography.Apple.
6274 #
6275 # On Desktop, we can check at runtime whether the OS version is recent enough and switch
6276 # implementation accordingly. We build a single `libmono-native` shared library.
6277 #
6278 # However, on Mobile we cannot have any undefined symbols as this would break Bitcode.
6279 #
6280 # During the mobile build, we are called with `CFLAGS` containing an explicit minium version flag,
6281 # which is eiter `-mmacosx-version-min=`, `-mios-simulator-version-min=` or `-miphoneos-version-min=`
6282 # depending on platform.
6283 #
6284 # We build two versions of the shared library:
6285 # - `libmono-native-compat` is built with whichever minimum version is passed to us via `CFLAGS`.
6286 # - `libmono-native-unifed` is built with the minimum version set to macOS 10.12+ / iOS 10+.
6287 #
6288 # For testing purpuses, there is a function called `mono_native_get_platform_type ()`
6289 # (see mono/native/mono-native-platform.c), which returns a `MonoNativePlatformType` enum value.
6290 # There is also `Mono.MonoNativePlatform.GetPlatformType ()` (see mcs/class/corlib/Test/Mono/MonoNativePlatform.cs).
6291 #
6292 # This can be called by automated tests both to ensure that the library has been correctly installed and also
6293 # to verify that it's the correct version of it.

6464 dnl nosymbolic- is a hack in case -G for linking is used, as -G seems
6465 dnl to change the way unresolved symbols work on library load in an
6466 dnl incompatible manner. (as references to runtime functions are
6467 dnl resolved later) Default params otherwise are that, so seems OK.
6468 dnl Likewise, we don't seem to need to cover the entire runtime with
6469 dnl it either, on both AIX and PASE. -brtl from -G does seem to spew
6470 dnl Big Scary TOC Warnings (tm) from the linker, but it doesn't seem
6471 dnl problematic with gcc's -mminimal-toc.
6472 dnl ----
6473 dnl flock in AIX exists in libbsd (not the same as freedesktop.org
6474 dnl libbsd) which Mono.Native needs.
6475 dnl Because of the way that the library is built by default, unresolved
6476 dnl references are kept and resolved at runtime. Often, the dependency
6477 dnl chain means libbsd is loaded anyways, but not necessarily. It's
6478 dnl better to explicitly link it, even though it has it shadows libc's
6479 dnl ioctl with its own. (As for the other unresolved imports, those
6480 dnl should be provided by the Mono runtime loaded.)

6603 #
6604 # We have to lie to autotools, sometimes.
6605 #
6606 # If we're building with llvm compiled into Mono, set MONO_CXXLD to CXX,
6607 # otherwise to CC. We want C linking even if we're compiling with C++ enabled
6608 # because we do not want to link inthe C++ runtime library (-lstdc++ or -lc++),
6609 # except if we're linking with LLVM which relies on it.
6610 #
6611 # Explanation of the hack:
6612 #
6613 # According to
6614 # https://www.gnu.org/software/automake/manual/html_node/How-the-Linker-is-Chosen.html,
6615 # automake chooses the linker that it used to compile a target based on the
6616 # _SOURCES for that target. If the target is comprised of only C code, it
6617 # chooses the C linker (on Linux and OSX this is just gcc or clang called with
6618 # linker arguments and a -o). If the target _SOURCES include at least one C++ file,
6619 # then automake chooses the C++ linker (usually g++ or clang++ called with linker arguments and -o).
6620 #
6621 # The problem for Mono is that we don't want the C++ runtime library (libstdc++
6622 # or libc++) linked in - even when Mono is written in C++, we take care not to
6623 # require the runtime library. As a result, we don't want g++ or clang++ to do
6624 # the linking. On the other hand if LLVM is enabled, then we _must_ use the
6625 # C++ linker - LLVM doesn't have the same restrictions.
6626 #
6627 # So the trick is we set MONO_CXXLD here to $CXX or $CC and in
6628 # mono/mini/Makefile.am.in we have CCLD=$MONO_CXXLD and CXXLD=$MONO_CXXLD which bypasses
6629 # automake's autodetection and lets us use the linker that we want.
