即使与libole32链接,外部库中的未定义OLE引用也是如此

Question

使用MINGW,我试图将我的C代码链接到执行一些OLE操作的静态C++库:

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连接,但正如你所看到的,我已经这样做了.

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,在liboleaut32.
