480 dnl libtool cannot generate functioning svr4 sonames on

482 dnl Unfortunately, everything is complicated by the fact that
483 dnl gcc doesn't respect this variable. (otherwise we could set
484 dnl it for build time for configure and make)
485 dnl On IBM i PASE using IBM's packages, GCC *does* respect this
486 dnl variable, and builds are 64-bit by default. svr4 sonames
487 dnl must still be specified when configuring on i, however.
488 dnl As such, because Mono doesn't support 32-bit AIX or PASE,

503 dnl wrapper, which subtly breaks other things.

6340 # Mono.Native Support
6341 # -------------------
6342 # Mono.Native is the new name for both System.Native and System.Security.Cryptography.Apple.
6343 # It is built as a stand-alone shared library and not bundled with the runtime because we
6344 # may need to build two different versions of it.
6346 # Starting with macOS 10.12+ and iOS 10+, Apple introduced a new Unified API for some of the
6347 # crypto primitives that we're using as part of System.Security.Cryptography.Apple.
6349 # On Desktop, we can check at runtime whether the OS version is recent enough and switch
6350 # implementation accordingly. We build a single `libmono-native` shared library.
6352 # However, on Mobile we cannot have any undefined symbols as this would break Bitcode.
6354 # During the mobile build, we are called with `CFLAGS` containing an explicit minium version flag,
6355 # which is eiter `-mmacosx-version-min=`, `-mios-simulator-version-min=` or `-miphoneos-version-min=`
6356 # depending on platform.
6358 # We build two versions of the shared library:
6359 # - `libmono-native-compat` is built with whichever minimum version is passed to us via `CFLAGS`.
6360 # - `libmono-native-unifed` is built with the minimum version set to macOS 10.12+ / iOS 10+.
6362 # For testing purpuses, there is a function called `mono_native_get_platform_type ()`
6363 # (see mono/native/mono-native-platform.c), which returns a `MonoNativePlatformType` enum value.
6364 # There is also `Mono.MonoNativePlatform.GetPlatformType ()` (see mcs/class/corlib/Test/Mono/MonoNativePlatform.cs).
6366 # This can be called by automated tests both to ensure that the library has been correctly installed and also
6367 # to verify that it's the correct version of it.

6542 dnl nosymbolic- is a hack in case -G for linking is used, as -G seems
6543 dnl to change the way unresolved symbols work on library load in an
6544 dnl incompatible manner. (as references to runtime functions are
6545 dnl resolved later) Default params otherwise are that, so seems OK.
6546 dnl Likewise, we don't seem to need to cover the entire runtime with
6547 dnl it either, on both AIX and PASE. -brtl from -G does seem to spew
6548 dnl Big Scary TOC Warnings (tm) from the linker, but it doesn't seem
6549 dnl problematic with gcc's -mminimal-toc.
6551 dnl flock in AIX exists in libbsd (not the same as freedesktop.org
6552 dnl libbsd) which Mono.Native needs.
6553 dnl Because of the way that the library is built by default, unresolved
6554 dnl references are kept and resolved at runtime. Often, the dependency
6555 dnl chain means libbsd is loaded anyways, but not necessarily. It's
6556 dnl better to explicitly link it, even though it has it shadows libc's
6557 dnl ioctl with its own. (As for the other unresolved imports, those
6558 dnl should be provided by the Mono runtime loaded.)

6682 # We have to lie to autotools, sometimes.
6684 # If we're building with llvm compiled into Mono, set MONO_CXXLD to CXX,
6685 # otherwise to CC. We want C linking even if we're compiling with C++ enabled
6686 # because we do not want to link inthe C++ runtime library (-lstdc++ or -lc++),
6687 # except if we're linking with LLVM which relies on it.
6689 # Explanation of the hack:
6692 # https://www.gnu.org/software/automake/manual/html_node/How-the-Linker-is-Chosen.html,
6693 # automake chooses the linker that it used to compile a target based on the
6694 # _SOURCES for that target. If the target is comprised of only C code, it
6695 # chooses the C linker (on Linux and OSX this is just gcc or clang called with
6696 # linker arguments and a -o). If the target _SOURCES include at least one C++ file,
6697 # then automake chooses the C++ linker (usually g++ or clang++ called with linker arguments and -o).
6699 # The problem for Mono is that we don't want the C++ runtime library (libstdc++
6700 # or libc++) linked in - even when Mono is written in C++, we take care not to
6701 # require the runtime library. As a result, we don't want g++ or clang++ to do
6702 # the linking. On the other hand if LLVM is enabled, then we _must_ use the
6703 # C++ linker - LLVM doesn't have the same restrictions.
6705 # So the trick is we set MONO_CXXLD here to $CXX or $CC and in
6706 # mono/mini/Makefile.am.in we have CCLD=$MONO_CXXLD and CXXLD=$MONO_CXXLD which bypasses
6707 # automake's autodetection and lets us use the linker that we want.
