是不是少写什么代码？或者编译器选项少选了什么？

#pragma的具体用法由编译器自己定义，应该是你的编译器不支持这个语法吧，所以就给忽略了
你的用法好像只有微软的编译器才支持

那如果我需要共享这段数据假如不用#pragma data_seg该怎么实现？

[xunxun]

pragma是vc专有的语法 gcc等价方法是

#pragma data_seg("lucifd")
HHOOK pub_hook=NULL;
HWND pub_wndCaller=NULL;
#pragma data_seg()

->

HHOOK pub_hook __attribute__((section("lucifd")) =NULL;
HWND pub_wndCaller __attribute__((section("lucifd")) =NULL;

当然你可以把相同的部分define个
