发布SwiftUI项目中c++库(Pcapplusplus)的链接和编译

Question

我试图通过使用objective C桥类在我的SwiftUI应用程序中利用c++库Pcapplusplus。我已经编译了一个独立的c++可执行文件，它非常基本地使用了pcpp库，但我不知道如何在xcode中链接和编译它。下面是我用来在终端中运行独立可执行文件的两个makefile文件。抱歉，如果这是超级简单，我只是不确定这些makefiles将如何转化为xcode配置选项。感谢回复!

all:
g++ $(PCAPPP_BUILD_FLAGS) $(PCAPPP_INCLUDES) -c -o main.o main.cpp
g++ $(PCAPPP_LIBS_DIR) -o Tutorial-HelloWorld main.o $(PCAPPP_LIBS)
# Clean Target
clean:
rm main.o
rm Tutorial-HelloWorld

# All Target
all:
g++ $(PCAPPP_BUILD_FLAGS) $(PCAPPP_INCLUDES) -c -o main.o main.cpp
g++ $(PCAPPP_LIBS_DIR) -o Tutorial-HelloWorld main.o $(PCAPPP_LIBS)
# Clean Target
clean:
rm main.o
rm Tutorial-HelloWorld

以下是在SwiftUI项目中构建PcapPlusPlus的步骤:

1. 运行PcapPlusPlus配置脚本:

   ./configure-mac_os_x.sh --arm64
   

2. 构建PcapPlusPlus:

   make libs
   

3. 转到构建设置，并在"标题搜索路径"下;添加PcapPlusPlus包含目录
4. 在"其他链接标志"下;添加:

   -L/usr/local/lib -lpcap, -lpthread $(inherited)
   

5. 在项目设置的build phases选项卡下，在"Link Binary With libraries"中加入SystemConfig、corefoundation、libCommon++.a、libPacket++.a、libPcap++.a框架
