6250 # Mono.Native Support
6251 # -------------------
6252 # Mono.Native is the new name for both System.Native and System.Security.Cryptography.Apple.
6253 # It is built as a stand-alone shared library and not bundled with the runtime because we
6254 # may need to build two different versions of it.
6255 #
6256 # Starting with macOS 10.12+ and iOS 10+, Apple introduced a new Unified API for some of the
6257 # crypto primitives that we're using as part of System.Security.Cryptography.Apple.
6258 #
6259 # On Desktop, we can check at runtime whether the OS version is recent enough and switch
6260 # implementation accordingly. We build a single `libmono-native` shared library.
6261 #
6262 # However, on Mobile we cannot have any undefined symbols as this would break Bitcode.
6263 #
6264 # During the mobile build, we are called with `CFLAGS` containing an explicit minium version flag,
6265 # which is eiter `-mmacosx-version-min=`, `-mios-simulator-version-min=` or `-miphoneos-version-min=`
6266 # depending on platform.
6267 #
6268 # We build two versions of the shared library:
6269 # - `libmono-native-compat` is built with whichever minimum version is passed to us via `CFLAGS`.
6270 # - `libmono-native-unifed` is built with the minimum version set to macOS 10.12+ / iOS 10+.
6271 #
6272 # For testing purpuses, there is a function called `mono_native_get_platform_type ()`
6273 # (see mono/native/mono-native-platform.c), which returns a `MonoNativePlatformType` enum value.
6274 # There is also `Mono.MonoNativePlatform.GetPlatformType ()` (see mcs/class/corlib/Test/Mono/MonoNativePlatform.cs).
6275 #
6276 # This can be called by automated tests both to ensure that the library has been correctly installed and also
6277 # to verify that it's the correct version of it.

6448 dnl nosymbolic- is a hack in case -G for linking is used, as -G seems
6449 dnl to change the way unresolved symbols work on library load in an
6450 dnl incompatible manner. (as references to runtime functions are
6451 dnl resolved later) Default params otherwise are that, so seems OK.
6452 dnl Likewise, we don't seem to need to cover the entire runtime with
6453 dnl it either, on both AIX and PASE. -brtl from -G does seem to spew
6454 dnl Big Scary TOC Warnings (tm) from the linker, but it doesn't seem
6455 dnl problematic with gcc's -mminimal-toc.
6456 dnl ----
6457 dnl flock in AIX exists in libbsd (not the same as freedesktop.org
6458 dnl libbsd) which Mono.Native needs.
6459 dnl Because of the way that the library is built by default, unresolved
6460 dnl references are kept and resolved at runtime. Often, the dependency
6461 dnl chain means libbsd is loaded anyways, but not necessarily. It's
6462 dnl better to explicitly link it, even though it has it shadows libc's
6463 dnl ioctl with its own. (As for the other unresolved imports, those
6464 dnl should be provided by the Mono runtime loaded.)

6587 #
6588 # We have to lie to autotools, sometimes.
6589 #
6590 # If we're building with llvm compiled into Mono, set MONO_CXXLD to CXX,
6591 # otherwise to CC. We want C linking even if we're compiling with C++ enabled
6592 # because we do not want to link inthe C++ runtime library (-lstdc++ or -lc++),
6593 # except if we're linking with LLVM which relies on it.
6594 #
6595 # Explanation of the hack:
6596 #
6597 # According to
6598 # https://www.gnu.org/software/automake/manual/html_node/How-the-Linker-is-Chosen.html,
6599 # automake chooses the linker that it used to compile a target based on the
6600 # _SOURCES for that target. If the target is comprised of only C code, it
6601 # chooses the C linker (on Linux and OSX this is just gcc or clang called with
6602 # linker arguments and a -o). If the target _SOURCES include at least one C++ file,
6603 # then automake chooses the C++ linker (usually g++ or clang++ called with linker arguments and -o).
6604 #
6605 # The problem for Mono is that we don't want the C++ runtime library (libstdc++
6606 # or libc++) linked in - even when Mono is written in C++, we take care not to
6607 # require the runtime library. As a result, we don't want g++ or clang++ to do
6608 # the linking. On the other hand if LLVM is enabled, then we _must_ use the
6609 # C++ linker - LLVM doesn't have the same restrictions.
6610 #
6611 # So the trick is we set MONO_CXXLD here to $CXX or $CC and in
6612 # mono/mini/Makefile.am.in we have CCLD=$MONO_CXXLD and CXXLD=$MONO_CXXLD which bypasses
6613 # automake's autodetection and lets us use the linker that we want.
