我现在已经经过一番努力到只剩下几个错误了,还望各大侠指点迷津!为什么还有以下错误?如何解决?拜托拜托!!!!!!!

命令:[root@localhost home]# arm-elf-gcc -c adc.c -elf2flt -mcpu=arm7ttmi -D__KERNEL__ -DMODULE -O2 -Os -g -Wall -D__linux__ -o adc

显示信息:

是-mcpu=arm7tdmi

还不行喔,还是原来的错误  :-(

tcz

能生成目标文件吗？

miller25

可以,但不知是否可以运行

tcz

原因在于在多个头文件中都有那几个men*函数的定义，能用的话就该没什么问题。
