标题[问题] 请问有关dll问题(VC++6)
时间Thu Oct 20 00:34:49 2016
开发平台(Platform): (Ex: Win10, Linux, ...)
Windows xp
编译器(Ex: GCC, clang, VC++...)+目标环境(跟开发平台不同的话需列出)
visual studio c++ 6
额外使用到的函数库(Library Used): (Ex: OpenGL, ...)
export dll/import dll
问题(Question):
因为某种特殊硬体原因, 必须使用VC+6开发
我在使用Dev C+制做dll档後, 使用VC+6 Import dll, 可以正常呼叫dll中的API
但在使用VC++6制作DLL档後, VC++6 载入却失败, 表示位置措误,
而使用dependency Walker Win32去检视该VC++做出的dll档, 则出现乱码:

载入及载出的专案:
https://mega.nz/#!khpGHAKK!ZR1-wIQ3qgnJy4lFfKUys7xo54SNPzYhqtWhUfsVOY8
请教各位前辈, VC++6制出DLL 有什麽SOP吗?
个人别无所求, 只要能向Dev C++一样制出 可以被LoadLibrary就好

1F:→ stupid0319: 因为C++支援多载含数,汇出的含数要包extern "C"什麽的 10/20 06:52
2F:→ stupid0319: 小弟也不是很懂,胡乱猜的 10/20 06:52
再次感谢S大神
我在function define前, 包一个extern c
在denpendency就能看到了
感谢
