We want C linking even if we're compiling with C++ enabled # because we do not want to link inthe C++ runtime library (-lstdc++ or -lc++), # except if we're linking with LLVM which relies on it. # # Explanation of the hack: # # According to # https://www.gnu.org/software/automake/manual/html_node/How-the-Linker-is-Chosen.html, # automake chooses the linker that it used to compile a target based on the # _SOURCES for that target. If the target is comprised of only C code, it # chooses the C linker (on Linux and OSX this is just gcc or clang called with # linker arguments and a -o). If the target _SOURCES include at least one C++ file, # then automake chooses the C++ linker (usually g++ or clang++ called with linker arguments and -o). # # The problem for Mono is that we don't want the C++ runtime library (libstdc++ # or libc++) linked in - even when Mono is written in C++, we take care not to # require the runtime library. As a result, we don't want g++ or clang++ to do # the linking. On the other hand if LLVM is enabled, then we _must_ use the # C++ linker - LLVM doesn't have the same restrictions. # # So the trick is we set MONO_CXXLD here to $CXX or $CC and in # mono/mini/Makefile.am.in we have CCLD=$MONO_CXXLD and CXXLD=$MONO_CXXLD which bypasses # automake's autodetection and lets us use the linker that we want. # if test "x$enable_llvm_runtime" = "xyes"; then AC_SUBST(MONO_CXXLD, [$CXX]) AC_SUBST(MONO_LIBTOOL_TAG, '--tag=CXX') else AC_SUBST(MONO_CXXLD, [$CC]) AC_SUBST(MONO_LIBTOOL_TAG, '') fi ### Set -Werror options # # Anything involving -Werror must be done late because autoconf depends on compiling with warnings to be success. # if test x"$GCC" = xyes; then if test "x$with_jemalloc" != "xyes"; then # incompatible-pointer-types requires gcc circa 5.x ORIG_CFLAGS=$CFLAGS CFLAGS="$CFLAGS -Wincompatible-pointer-types -Werror" AC_MSG_CHECKING(for -Wincompatible-pointer-types option to gcc) AC_TRY_COMPILE([],[ ], [ AC_MSG_RESULT(yes) CFLAGS="$ORIG_CFLAGS -Werror=incompatible-pointer-types" ], [ AC_MSG_RESULT(no) CFLAGS=$ORIG_CFLAGS ]) CFLAGS="$CFLAGS -Werror=return-type" fi # Implicit function declarations are not 64 bit safe # Do this late, since this causes lots of configure tests to fail CFLAGS="$CFLAGS -Werror-implicit-function-declaration" # jay has a lot of implicit declarations JAY_CFLAGS="-Wno-implicit-function-declaration" ORIG_CFLAGS=$CFLAGS CFLAGS="$CFLAGS -Wsometimes-uninitialized -Werror" AC_MSG_CHECKING(for -Wsometimes-uninitialized option to gcc) AC_TRY_COMPILE([],[ ], [ AC_MSG_RESULT(yes) CFLAGS="$ORIG_CFLAGS -Werror=sometimes-uninitialized" ], [ AC_MSG_RESULT(no) CFLAGS=$ORIG_CFLAGS ]) fi # zlib/configure checks if this program compiles and if so # defines _LARGEFILE64_SOURCE on the compiler command line (not config.h). # AC_MSG_CHECKING([for large file support]) AC_COMPILE_IFELSE( [AC_LANG_SOURCE([ #include off64_t dummy = 0; ])], [ AC_MSG_RESULT(yes) # FIXME The ramifications of _LARGEFILE64_SOURCE are not understood. # ZLIB_CFLAGS="$ZLIB_CFLAGS -D_LARGEFILE64_SOURCE=1" ], [ AC_MSG_RESULT(no) ]) AC_SUBST(CFLAGS) AC_SUBST(CPPFLAGS) AC_SUBST(LDFLAGS) AC_SUBST(CCLDFLAGS) AC_SUBST(ZLIB_CFLAGS) # Update all submodules recursively to ensure everything is checked out (cd $srcdir && scripts/update_submodules.sh) AC_MONO_OUTPUT() if test x$host_win32 = xyes; then # Get rid of 'cyg' prefixes in library names sed -e "s/\/cyg\//\/\//" libtool > libtool.new; mv libtool.new libtool; chmod 755 libtool # libtool seems to inherit -mno-cygwin from our CFLAGS, and uses it to compile its executable # wrapper scripts which use exec(). gcc has no problem compiling+linking this, but the resulting # executable doesn't work... sed -e "s,-mno-cygwin,,g" libtool > libtool.new; mv libtool.new libtool; chmod 755 libtool fi if test x$host_darwin = xyes; then # This doesn't seem to be required and it slows down parallel builds sed -e 's,lock_old_archive_extraction=yes,lock_old_archive_extraction=no,g' < libtool > libtool.new && mv libtool.new libtool && chmod +x libtool fi ( case $prefix in NONE) prefix=$ac_default_prefix ;; esac case $exec_prefix in NONE) exec_prefix='${prefix}' ;; esac # # If we are cross compiling, we don't build in the mcs/ tree.
