[英]undefined reference to mmap and munmap
I'm totally newbie in UNIX project compiling. 我是UNIX项目编译的新手。 I need help or advice in using of Cygwin.
我在使用Cygwin时需要帮助或建议。 An errors on "MAKE" command make me upset:
“ MAKE”命令上的错误使我不高兴:
/player_module.cpp:96: undefined reference to `mmap'
/player_module.cpp:136: undefined reference to `munmap'
player_module.cpp has includes: player_module.cpp包括:
#include <stdio.h>
#include <string.h>
#include <sys/mman.h>
Invocation code looks like: 调用代码如下:
dump_start = mmap( NULL, sb.st_size, PROT_READ, MAP_SHARED, fileno( file ), 0 );
munmap( dump_start, sb.st_size );
As far as I understand the problem is with sys/mman.h include, but I don't have any clue how to resolve it. 据我了解,问题出在sys / mman.h include,但我不知道如何解决。 Any help would be appreciated.
任何帮助,将不胜感激。
PS. PS。 I don't know anything about UNIX, GCC or things like that, because I do only windows stuff.
我对UNIX,GCC或类似的东西一无所知,因为我只做Windows的事情。
