[Mingw-users] MSVC import library confusion

[<Chr...@in...>]

Hi all,

I got some MSVC dll (along with the according .lib files) which I tried
to link to a project developed with minGW under Eclipse CDT. My problem
is, that the linker gives me unresolved references whenever I try to
create instances for objects stored in those dlls.

I found various resources on the web dealing with this and so I played
around with pexports and dlltool like this:

	pexports my.dll >my.def=20
	dlltool -U -d my.def -l libmy.a

I tried to link my program against the .dll, the .lib and the .a files
(using the -l flag). Nothing worked.

The class definitions in the header files look like this:
=09
	class __declspec(dllimport) Utils

Within my main program I simply try to call the constructor, but the
linker gives me:

	undefined reference to `MyNameSpace::Utils::Utils()'

The .def file created by pexports looks like:

	LIBRARY my.dll
	EXPORTS
	??1Utils@MyNameSpace@@UAE@XZ
	??4Utils@MyNameSpace@@QAEAAV01@ABV01@@Z=09
	??_7Utils@MyNameSpace@@6B@ DATA=09

All those '?' and '@' look weird and do not match with the formats I
found at http://wyw.dcweb.cn/stdcall.htm


How does a valid .def file have to look like?=20

Thanks for your help
