如何用gcc静态链接SDL库？

Question

当我这样做（动态链接）时，一切都很好：

$ gcc -o beta.bin ./game.c -lSDL -lSDLmain

但是当我尝试静态链接时：

$ gcc -static -o beta.bin ./game.c -lSDL -SDLmain

存在链接器问题：

/usr/local/bin/ld: /usr/local/lib/libSDL.a(SDL_aavideo.o): in function `AA_VideoInit':
SDL_aavideo.c:(.text+0x376): undefined reference to `aa_parseoptions'
/usr/local/bin/ld: SDL_aavideo.c:(.text+0x37b): undefined reference to `aa_defparams'
/usr/local/bin/ld: SDL_aavideo.c:(.text+0x380): undefined reference to `aa_autoinit'
#...more (log1.txt)
collect2: error: ld returned 1 exit status

我尝试显式指定静态库：

$ gcc -static -o beta.bin ./game.c /usr/local/lib/libSDL.a /usr/local/lib/libSDLmain.a /usr/lib/libm.a

黄道。没成功。

谢谢，神圣黑猫。 我尝试运行conf来找出必要的标志：

$ pkgconf --libs --static sdl

pkgconf 命令的结果:

-L/usr/local/lib -Wl,-rpath,/usr/local/lib -lSDL -pthread -lSDL -pthread -lm -laa -lusbhid -pthread

但即使有这样一组标志，也会发生链接器错误。然而，错误是不同的。

$ gcc -static -o beta.bin ./game.c -L/usr/local/lib -Wl,-rpath,/usr/local/lib -lSDL -pthread -lSDL -pthread -lm -laa -lusbhid -pthread

gcc的结果

/usr/local/bin/ld: /usr/local/lib/libaa.a(aacurses.o): in function `curses_init':
aacurses.c:(.text+0x1f): undefined reference to `initscr'
/usr/local/bin/ld: aacurses.c:(.text+0x48): undefined reference to `termattrs'
/usr/local/bin/ld: aacurses.c:(.text+0x68): undefined reference to `stdscr'
/usr/local/bin/ld: aacurses.c:(.text+0x6f): undefined reference to `intrflush'
#...more (log2.txt)

所以我认为也有必要考虑 nсurses 标志。

$ pkgconf --libs --static ncurses
-fstack-protector-strong -Wl,-rpath,/usr/local/lib -lncurses -ltinfo
$ gcc -static -o beta.bin ./game.c -L/usr/local/lib -Wl,-rpath,/usr/local/lib -lSDL -pthread -lSDL -pthread -lm -laa -lusbhid -pthread -fstack-protector-strong -Wl,-rpath,/usr/local/lib -lncurses -ltinfo

而且看起来已经编译成功了。但事实并非如此。当我运行程序时，我在 ncurses 中得到输出：

$./beta.bin

如果在没有 -static 标志的情况下编译，结果会很好。但由于某种原因， -static 标志给出了 ncurses 中的结果。 在此输入图片描述
