C <；决议h>；在OpenBSD上提供不完整的类型错误

我在linux、osx、windows和solaris上编译，但在OpenBSD上，当包含

resolv.h

时，编译失败。这是OpenBSD中的错误吗？我应该（不）先包括一些其他标题吗

egcc -std=gnu99 -I/usr/local/lib/R/include -DNDEBUG -I/usr/include -I/usr/local/include    -fpic  -O2 -pipe  -c ssl.c -o ssl.o

评论中给出了正确答案：

#include <netinet/in.h>
#include <resolv.h>

#包括
#包括

9K用户应该知道代码必须被发布，而不是链接…尝试在

resolv.h

之前包含

，但它应该位于
resolv.h
的顶部。谢谢你的帮助。
