Question

我正在尝试使用Makefile创建项目。 Makefile适用于其他Mac，但在我的情况下会带来错误。

输出如下：

makefile已经在Linux平台上测试过，而且运行正常。任何建议，我的Mac c ++配置中有什么错误？

我正在使用MacOS High Sierra（10.13）和Xcode v9.0.1

被修改

这是编译命令：

Answer 1

我建议您运行gcc -x c++，或者在MacOS上运行g++，而不是clang++。

此外，您的编译行似乎缺少-c选项，它会告诉编译器生成目标文件;没有它，它会尝试链接你的文件并创建一个可执行文件。

此外，我发现您已将-D__i386__和-D__ppc64__添加到编译行非常奇怪：这些通常是由您的操作系统定义的系统宏，而不是在命令行上提供的编译器。

另一个潜在的问题是您使用-I将系统头文件目录显式添加到编译行。编译器将自己添加它们，并使用正确的配置。系统标头通常需要额外注意以正确的顺序包含等。

如果您更改到正确的目录并从shell提示符运行：

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

编译得当吗？

升级您的包裹：

$ brew update
$ brew upgrade

随着XCode的更新，它可以修复。
