我正在尝试使用Makefile创建项目。 Makefile可以在其他Mac上正常工作，但在我的情况下会带来错误。
输出如下:

该makefile已在Linux平台上经过测试，并且可以正常工作。
有什么建议，我的Mac c++配置有什么问题？
我正在使用MacOS High Sierra(10.13)和Xcode v9.0.1

这是编译命令:
gcc -pipe -x c++ -std=c++11 -fPIC -pedantic -W -Wall -Wwrite-strings -Wcast-align -Wcast-qual -Wpointer-arith -Wshadow -Wendif-labels -Wundef -Wfloat-equal -Werror -Wconversion -DPROJECT_VERSION="0.0.1" -DUSE_SDK="no" -g -g3 -ggdb3 -D__i386__=1 -D__ppc64__=0 -Wno-sign-conversion -Wno-conversion -Wno-float-equal -Wno-unused-parameter -I/usr/local/include -I/usr/local/opt/openssl/include -I/usr/local/include -I/usr/local/opt/openssl/include -I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/usr/include -I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/usr/include/c++/version -I/git/p2p/inc -I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/usr/include -I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/usr/include/c++/version src/kernel.cpp -o /git/p2p/obj/kernel.o
最佳答案
建议您不要运行gcc -x c++，而最好在MacOS上运行g++，而不是clang++。
另外，您的编译行似乎缺少-c选项，该选项将告诉编译器生成目标文件。否则，它将尝试链接文件并创建可执行文件。
同样，我发现将-D__i386__和-D__ppc64__添加到编译行中也很奇怪:这些通常是操作系统定义的系统宏，未在编译器的命令行上提供。
另一个潜在的问题是，为什么要使用-I将系统头文件目录显式添加到编译行中。编译器将自己添加这些，并使用适当的配置。系统标题通常需要格外小心，以正确的顺序包括在内。
如果更改到正确的目录并从 shell 程序提示符运行此目录:
clang++ -pipe -std=c++11 -fPIC -pedantic -W -Wall -Wwrite-strings \
-Wcast-align -Wcast-qual -Wpointer-arith -Wshadow -Wendif-labels \
-Wundef -Wfloat-equal -Werror -Wconversion -DPROJECT_VERSION="0.0.1" \
-DUSE_SDK="no" -g -g3 -ggdb3 -Wno-sign-conversion -Wno-conversion \
-Wno-float-equal -Wno-unused-parameter -I/usr/local/include \
-I/usr/local/opt/openssl/include -I/git/p2p/inc \
-c -o /git/p2p/obj/kernel.o src/kernel.cpp
它可以正确编译吗？
