即使与 libole32 链接，外部库中也未定义 OLE 引用

Question

使用 MINGW，我尝试将我的 C 代码与执行一些 OLE 操作的静态 C++ 库链接：

mingw32-gcc main.o resources.o -o mbcom.exe -L../../Lib/Iup -liup -liupole -lole32 -lcomctl32 -lstdc++ -mwindows

不幸的是，我得到了这个：

我能找到的唯一解决方案是与 libole32 链接，但正如你所看到的，我已经在这样做了。

还有其他想法吗？

Answer 1

libuuid 是应该找到这些东西的地方。

除了 VariantInit，它位于 liboleaut32 中。
