c - 编译和链接多个 C 库（卡在未找到架构 x86_64 的符号）
问题描述
我基本上是在尝试编译以下 repo。 https://github.com/zhaozg/lui
以下是我到达的地方：（如果我遵循的步骤可能完全错误，我很抱歉，因为我是 C 和 GCC 的新手，我只是尽力把这个难题放在一起）
它有两个依赖项：
我能够从上述 2 个项目中生成两个文件：
- liblua.a
- libui.a
到目前为止我很高兴，但我无法弄清楚如何使用上述 .a 文件并编译 zhaozg/lui 项目。
github中编译说明如下：
gcc -shared -Isrc src/lui.c -I{LUAINCDIR} -I{LIBUVINCDIR} -lui -llua-5.1 -o luv.so
另外，我试图将编译后的文件保存在本地，而不是将它们复制到 /usr/local
所以，几个小时后，我到达了以下步骤：
gcc -shared -v -Isrc src/lui.c -I ../lua-src -I ../libui /Users/silva/Documents/test00x/lui/liblua.a /Users/silva/Documents/test00x/lui/libui.a
但是现在我遇到了以下错误：
gcc -shared -v -Isrc src/lui.c -I ../lua-src -I ../libui /Users/silva/Documents/test00x/lui/liblua.a /Users/silva/Documents/test00x/lui/libui.a

解决方案
对于那些在 Mac OS 中遇到这个问题的人，
gcc -shared -v -framework Foundation -framework AppKit -Isrc src/lui.c ...etc
使用静态库时，您还必须显式链接系统库，
静态库只是一堆 .o 文件；它们不包含有关外部依赖项的任何信息。
