make V=s에서 make[number]는 무엇을 의미하나요?

Question

make V=s의 전체 로그를 읽을 수 있도록 활성화하면 make. 나는 항상 make[numer]로그에서 본다.
예:

datle@debian:~/workspace/cpx/trunk$ make
rm -rf openwrt/tmp
cp config/defaut.config openwrt/.config
cd openwrt && make
make[1]: Entering directory `/home/datle/workspace/cpx/trunk/openwrt'
make[1]: Leaving directory `/home/datle/workspace/cpx/trunk/openwrt'
make[1]: Entering directory `/home/datle/workspace/cpx/trunk/openwrt'

나는 읽었다매뉴얼을 만들다하지만 이에 대한 자세한 내용은 찾지 못했습니다.

Answer 1

이 숫자는 를 나타내며 makelevel, 이를 통해 하위 make가 최상위 와 어떻게 관련되는지 알 수 있습니다 make.

이것은 make의 재귀적 사용입니다. 자세한 내용을 참조하세요.여기.

소스코드를 살펴보면 make좀 더 명확한 것을 볼 수 있습니다.

안에 main.c:

/* Value of the MAKELEVEL variable at startup (or 0).  */                       

unsigned int makelevel;

그런 다음:

/* Figure out the level of recursion.  */                                     
  {                                                                             
    struct variable *v = lookup_variable (STRING_SIZE_TUPLE (MAKELEVEL_NAME));  
    if (v && v->value[0] != '\0' && v->value[0] != '-')                         
      makelevel = (unsigned int) atoi (v->value);                               
    else                                                                        
      makelevel = 0;                                                            
  }

안에 output.c:

/* Use entire sentences to give the translators a fighting chance.  */        
  if (makelevel == 0)                                                           
    if (starting_directory == 0)                                                
      if (entering)                                                             
        fmt = _("%s: Entering an unknown directory\n");                         
      else                                                                      
        fmt = _("%s: Leaving an unknown directory\n");                          
    else                                                                        
      if (entering)                                                             
        fmt = _("%s: Entering directory '%s'\n");                               
      else                                                                      
        fmt = _("%s: Leaving directory '%s'\n");                                
  else

그리고 인쇄하기 전에 출력 형식을 지정하십시오.

if (makelevel == 0)                                                           
    if (starting_directory == 0)                                                
      sprintf (p, fmt , program);                                               
    else                                                                        
      sprintf (p, fmt, program, starting_directory);                            
  else if (starting_directory == 0)                                             
    sprintf (p, fmt, program, makelevel);                                       
  else                                                                          
    sprintf (p, fmt, program, makelevel, starting_directory);                   

  _outputs (NULL, 0, buf);
