c++ - 尝试静态链接我的基于 SDL2 的程序时对所有函数的未定义引用错误

Question

我想静态链接我的基于 C++ SDL2 的程序，但它没有按预期工作。

我已经将所有头文件、我的程序和libSDL2main.a文件放在一个文件夹中。然后我尝试编译程序。

g++ -c Static_linking.cpp -o static.o完美运行

g++ static.o libSDL2main.a -o static但是这条线给了我很多链接错误。

/usr/bin/ld: static.o: in function `main':
Static_linking.cpp:(.text+0x15): undefined reference to `SDL_Init'
/usr/bin/ld: Static_linking.cpp:(.text+0x3c): undefined reference to `SDL_CreateWindow'

/usr/bin/ld: Static_linking.cpp:(.text+0x93): undefined reference to `SDL_RenderPresent'
/usr/bin/ld: Static_linking.cpp:(.text+0x9d): undefined reference to `SDL_Delay'
/usr/bin/ld: Static_linking.cpp:(.text+0xa9): undefined reference to `SDL_DestroyWindow'
/usr/bin/ld: Static_linking.cpp:(.text+0xb5): undefined reference to `SDL_DestroyRenderer'
/usr/bin/ld: Static_linking.cpp:(.text+0xca): undefined reference to `SDL_Quit'
collect2: error: ld returned 1 exit status

PS：当我动态链接程序时，一切正常： g++ Static_linking.cpp -lSDL2 -o static

新发现

我错了，实际上有一个名为的文件libSDL2.a（我不知道为什么当我搜索它时它没有出现在文件中）。

虽然当我尝试时g++ static.o libSDL2main.a libSDL2.a -o static它给了我一个如此可怕和大的消息错误，我只会在这里展示开始。
