【问题描述】:
我正在使用 Dev-C++ 4.9.9.2 和 MinGW 来编译这段代码:
/* get the information about the group. */
struct group* group_info = getgrnam("PLACEHOLDER");
/* make sure this group actually exists. */
if (!group_info) {
printf("group 'PLACEHOLDER' does not exist.\n");
}
else
{
char** p_member;
printf("Here are the members of group 'PLACEHOLDER':\n");
for (p_member = group_info->gr_mem; *p_member; p_member++)
printf(" %s\n", *p_member);
}
}
我包含了以下头文件:
- grp.h
- sys/types.h
(从 glibc 2.13 获得它们(也许这是错误的,但一位朋友告诉我这是正确的方法))
当我尝试编译代码时,我在 glibc 的标头中收到一堆错误,例如:
12 C:\glibc-2.9\include\sys\cdefs.h expected constructor, destructor, or type conversion before '(' token
12 C:\glibc-2.9\include\sys\cdefs.h expected `,' or `;' before '(' token
4 C:\glibc-2.9\include\grp.h expected constructor, destructor, or type conversion before '(' token
编辑:
这是整个代码
#include <grp.h> /* defines 'struct group', and getgrnam(). */
#include <sys/types.h> /* defines 'gid_t', etc. */
BOOL getListOfGroupMembers() {
/* get the information about the "strange" group. */
struct group* group_info = getgrnam("PLACEHOLDER");
/* make sure this group actually exists. */
if (!group_info) {
printf("group 'PLACEHOLDER' does not exist.\n");
}
else
{
char** p_member;
printf("Here are the members of group 'PLACEHOLDER':\n");
for (p_member = group_info->gr_mem; *p_member; p_member++)
{
printf(" %s\n", *p_member);
}
}
return 0;
}
bool 返回目前没有意义,我想在编译时更改它。

在您的包含之前您似乎有问题。你能把这些部分贴出来吗?
