busybox-1.20.2 编译不过解决

 vim include/libbb.h 

在头文件里加一句 

 #include <sys/resource.h>

 

最后如下：

#include <sys/poll.h>

#include <sys/ioctl.h>

#include <sys/mman.h>

#include <sys/resource.h>      //add this file

#include <sys/socket.h>

#include <sys/stat.h>

#include <sys/time.h>

1. 要不会出现如下错误:
   
2. loginutils/passwd.c: In function ‘passwd_main’:
   
3. loginutils/passwd.c:104:16: error: storage size of ‘rlimit_fsize’ isn’t known
   
4. loginutils/passwd.c:188:2: warning: implicit declaration of function ‘setrlimit’ [-Wimplicit-function-declaration]
   
5. loginutils/passwd.c:188:12: error: ‘RLIMIT_FSIZE’ undeclared (first use in this function)
   
6. loginutils/passwd.c:188:12: note: each undeclared identifier is reported>for each function it appears in
