编译和链接多个 C 库(卡在未找到架构 x86_64 的符号处)

Question

我基本上正在尝试编译以下存储库。 https://github.com/zhaozg/lui

以下是我到达的位置:(如果我遵循的步骤可能完全错误，我很抱歉，因为我总体上是 C 和 GCC 的新手，我只是尽力将这个难题整合在一起)

它有两个依赖项:

1. https://github.com/andlabs/libui
2. Lua 来自 https://www.lua.org/download.html

我能够从上述 2 个项目生成两个文件:

1. liblua.a
2. libui.a

到目前为止我很高兴，但我不知道如何使用上面的.a文件并编译zhaozg/lui项目。

github上编译说明如下:

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留在本地，而不是将它们复制到/usr/local

所以，几个小时后，我达到了以下步骤:

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

对于那些在 Mac 操作系统中遇到此问题的人，

gcc -shared -v -framework Foundation -framework AppKit -Isrc src/lui.c ...等


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；它们不包含任何有关外部依赖项的信息。
