macos build fails

[aboeing]

Trying to build, with this command: cmake -DCMAKE_CXX_COMPILER=clang -DCMAKE_C_COMPILER=clang -DCMAKE_BUILD_TYPE="Release" .. make Get this linking error:

[ 22%] Linking CXX shared library ../bin/libeasy_profiler.dylib Undefined symbols for architecture x86_64: "std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator>::compare(unsigned long, unsigned long, char const*, unsigned long) const", referenced from: bool std::__1::operator==<char, std::__1::char_traits, std::__1::allocator>(std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator> const&, char const*) in profile_manager.cpp.o "std::__1::__vector_base_common::__throw_length_error() const", referenced from: std::__1::vector<BlockDescriptor*, std::__1::allocator<BlockDescriptor*>>::__recommend(unsigned long) const in profile_manager.cpp.o std::__1::vector<std::__1::reference_wrapperprofiler::Block, std::__1::allocator<std::__1::reference_wrapperprofiler::Block>>::__recommend(unsigned long) const in profile_manager.cpp.o std::__1::vector<CSwitchBlock, std::__1::allocator<CSwitchBlock>>::__recommend(unsigned long) const in profile_manager.cpp.o std::__1::vector<std::__1::thread, std::__1::allocatorstd::__1::thread>::__recommend(unsigned long) const in reader.cpp.o std::__1::vector<profiler::SerializedBlockDescriptor*, std::__1::allocatorprofiler::SerializedBlockDescriptor*>::__recommend(unsigned long) const in reader.cpp.o std::__1::vector<char, std::__1::allocator>::__recommend(unsigned long) const in reader.cpp.o std::__1::vector<profiler::BlocksTree, std::__1::allocatorprofiler::BlocksTree>::__recommend(unsigned long) const in reader.cpp.o ...

Seems to be missing linking to standard library. Anyone know how to fix this?

Hi!

Thank you for your feedback.

Try adding the following option to your CMake command:

-DCMAKE_CXX_FLAGS="-stdlib=libc++"

Let me know if this helps!
