-D__linux__

mwq

为什么要用-D__linux__呢?我不是用在linux上的,我是用在uclinux上的.你的这个参数是什么意思呢??

WindTrace

试一下这个？
#arm-elf-gcc -Wall -elf2flt -mcpu=arm7tdmi hello.c -lc -o hello

yinbinchao

我的错误一样的,但我用的是-D__linux__,哪位大虾帮帮忙,谢了!

lxkui

以上的错误问题有人解决了吗，在线等，谢谢

kuperl

If it is indeed named arm-elf-gcc, it might not be compiled for Linux.. If it does not define __linux__, linux/coda.h will not compile. If this is indeed the case, the real fix would be to fix the cross compiler. As a quick test, you could also just add -D__linux__ to CFLAGS.
