c++ - Make 在 Mac 上失败

Question

我正在尝试使用 Makefile 制作我的项目。 Makefile 适用于其他 Mac，但在我的情况下会出错。

输出如下:

makefile 已经在 Linux 平台上进行了测试，并且可以正常工作。有什么建议，我的 Mac C++ 配置有什么问题吗？

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

与其运行 gcc -x c++，我建议您运行 g++，或者在 MacOS 上运行 clang++ 更好。

此外，您的编译行似乎缺少 -c 选项，该选项会告诉编译器生成目标文件；否则它将尝试链接您的文件并创建一个可执行文件。

此外，我发现您在编译行中添加了 -D__i386__ 和 -D__ppc64__ 非常奇怪:这些通常是由操作系统定义的系统宏，不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。编译器将自己添加这些，并使用适当的配置。系统 header 通常需要格外小心，以正确的顺序包含在内。

如果您切换到正确的目录并从您的 shell 提示符运行此命令:

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

它是否正确编译？
