编译一个mod时提示一个库文件语法错误,有弟兄知道吗?

alpharay

编译module时提示如下


/usr/src/linux-2.4.20-8/include/linux/proc_fs.h:209: parse error before "void"

可自己看了代码找不出错误啊


编译命令是

gcc -D__KERNEL__ -I/usr/src/linux-2.4.20-8/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=i686 -DMODULE -DMODVERSIONS -include /usr/src/linux-2.4.20-8/include/linux/modversions.h -nostdinc -iwithprefix include -DKBUILD_BASENAME=db9 -c -o db9.o db9.c


有高手知道是怎么回事吗?

谢谢了!
