https://svn.boost.org/trac10/ticket/12150 <p> I'm trying to get a shared memory system working on OSX, as far as I can tell, it's calling posix_recursive_mutex::lock() without initalizing the mutex, which happens in the constructor. A breakpoint on line 78 of include/boost/interprocess/sync/posix/recursive_mutex.hpp never gets hit. </p> <p> Here is the output from my compiler attempt: </p> <pre class="wiki">g++ -v -I/usr/local/Cellar/boost/1.60.0/include -O0 -g -std=c++11 main.cpp Apple LLVM version 6.1.0 (clang-602.0.53) (based on LLVM 3.6.0svn) Target: x86_64-apple-darwin14.0.0 Thread model: posix "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang" -cc1 -triple x86_64-apple-macosx10.10.0 -emit-obj -mrelax-all -disable-free -disable-llvm-verifier -main-file-name main.cpp -mrelocation-model pic -pic-level 2 -mdisable-fp-elim -masm-verbose -munwind-tables -target-cpu core2 -target-linker-version 242.2 -v -gdwarf-2 -dwarf-column-info -resource-dir /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/clang/6.1.0 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk -I /usr/local/Cellar/boost/1.60.0/include -stdlib=libc++ -O0 -std=c++11 -fdeprecated-macro -fdebug-compilation-dir /Users/CPX-Hackintosh01/src/ruby/shm_test -ferror-limit 19 -fmessage-length 270 -stack-protector 1 -mstackrealign -fblocks -fobjc-runtime=macosx-10.10.0 -fencode-extended-block-signature -fcxx-exceptions -fexceptions -fmax-type-align=16 -fdiagnostics-show-option -fcolor-diagnostics -o /var/folders/96/hl850bv57w39vhdzqy2nykf00000gn/T/main-43ba41.o -x c++ main.cpp clang -cc1 version 6.1.0 based upon LLVM 3.6.0svn default target x86_64-apple-darwin14.0.0 ignoring nonexistent directory "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/c++/v1" ignoring nonexistent directory "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/local/include" ignoring nonexistent directory "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/Library/Frameworks" #include "..." search starts here: #include &lt;...&gt; search starts here: /usr/local/Cellar/boost/1.60.0/include /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/clang/6.1.0/include /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/System/Library/Frameworks (framework directory) End of search list.
