各位奆奆,这是怎么回事呢
C语言S1E2的作业,输入到linux系统中说我没有定义countLines很邪门是吗
/tmp/cciZRJto.o: In function `findAllDirs':
Codecounter.c:(.text+0x1d7): undefined reference to `countLines'
collect2: ld 返回 1

我是在Linux系统上照着打的,是系统的问题吗,就剩下这一个错误,比对了半天没问题,麻烦奆奆啦 qiuyouzhi 发表于 2020-7-1 17:57

奆奆,我前面打错了{:10_266:} {:10_249:} 一样的问题,哎,,,
