Question

我正在尝试将Python库包裹在C ++库周围，而distutils在OS X上对我来说是失败的。这是我setup.py中的相关内容：

if sys.platform.startswith("darwin"):
    extra_compile_args_setting = ["-std=c++1z", "-stdlib=libc++", "-O3"]

以下是相关输出：

clang -Wno-unused-result -Wsign-compare -Wunreachable-code -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I/Users/x/anaconda/include -arch x86_64 -I/Users/x/anaconda/include -arch x86_64 -I../../cpp_client/libsrc -I../../cpp_client/third_party -I/Users/x/anaconda/include/python3.6m -c navdb_python_client_wrap.cxx -o build/temp.macosx-10.7-x86_64-3.6/navdb_python_client_wrap.o -std=c++1z -stdlib=libc++ -O3

clang: warning: libstdc++ is deprecated; move to libc++ with a minimum deployment target of OS X 10.9 [-Wdeprecated]
ld: library not found for -lstdc++
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'clang++' failed with exit status 1

我最近升级到XCode10。该库似乎在那里：

$ ls -lrt /usr/lib/libstdc++*
lrwxr-xr-x  1 root  wheel       17 Sep 26  2017 /usr/lib/libstdc++.dylib -> libstdc++.6.dylib
lrwxr-xr-x  1 root  wheel       21 Sep 26  2017 /usr/lib/libstdc++.6.dylib -> libstdc++.6.0.9.dylib
-rwxr-xr-x  1 root  wheel  1461584 Mar 28 06:02 /usr/lib/libstdc++.6.0.9.dylib

欢迎任何帮助。

我没有卸载XCode命令行工具v10，而是安装了XCode命令行工具v9.4.1并解决了问题。

OS X：ld：找不到针对-lstdc ++
