Question

我有一个带有现有makefile的eclipse（Kepler）c / c ++项目，我想添加一个新的包含路径。

头文件的路径是：C：\ devkitPro \ tonclib \ include

我在C / C ++ General，Paths和Symbols下添加了项目设置的路径，我试图通过＆＃34; -I / c / devkitPro / tonclib / include＆＃34;来包含路径。在makefile中。

不知何故包含.h文件，但现在我得到了奇怪的错误：

make all 
Source: main.c metr.c
linking cartridge
main.o: In function `obj_test':
c:/Users/Christoph/gba_dev/Test/source/main.c:27: undefined reference to `key_poll'

collect2.exe: error: ld returned 1 exit status
make[1]: *** [/c/Users/Christoph/gba_dev/Test/Test.elf] Error 1

这是当前的makefile：

我不知道究竟是什么导致了这个问题，因为我之前从未使用过makefile，但我认为找不到根据头文件的.c文件。它们位于C：\ devkitPro \ tonclib \ src。

请有人指导我走向正确的方向吗？
