求助！如何解决这个连接错误error LNK2019

[Jhill]

各位大侠：
我碰到一个连接错误：
opennurbs_staticd.lib(opennurbs_uuid.obj) : error LNK2019: unresolved external symbol __imp__UuidCreate@4 referenced in function "bool __cdecl ON_CreateUuid(struct _GUID &)" (?ON_CreateUuid@@YA_NAAU_GUID@@@Z)。

opennurbs_staticd.lib是第三方库，有源码，其中opennurbs_uuid.cpp的源码是：

函数可以这样写?头一次见到

可能函数声明与实现有冲突了。

添加Rpcrt4.lib库到链接中。

[ndchenxiaofeng]

删除文件，重新编译~

[ccpaishi]

楼主是不是没有包含静态库，或者没有把头文件包含在工程中
