如何重新导出CLR C ++静态库

Question

I have these files:

• foo.dll
• foo.lib
• foo.exp
• bar.il
• bar.netmodule

"foo" defines functions in its export directory.

I also have a Visual Studio 2010 C++ project which will create a managed "bar.dll"

I want to "bar" to statically link to "foo" and reexport all functions from "foo".

In the end I want bar to export the functions from foo and some additional code defined in foo .

Using code below does not work as it references foo instead of merging bar with foo .

#pragma comment(linker, "/include:_foomethod@12")

How do I do that?

call "C:\Program Files\Microsoft Visual Studio 10.0\VC\bin\link.exe" /DLL /LTCG /CLRIMAGETYPE:IJW   /ASSEMBLYMODULE:bar.netmodule   /OUT:bar.dll foo.lib bar.netmodule

foo.netmodule : fatal error LNK1302: only support linking safe .netmodules; unable to link ijw/native .netmodule

Answer 1

I have figured it out.

Instead those files will be required:

• foo.obj
• bar.cpp
• bar.obj

The C++/CLI compiler cl.exe will be able to compile bar, reference unmanaged and managed worlds.

In a later step linker will be used to merge obj files into one mixed mode assembly containing:

• unmanaged exports from foo
• unmanaged exports from bar
• managed IL types from bar

Command used for linking obj files:

call "C:\Program Files\Microsoft Visual Studio 10.0\VC\bin\link.exe" /DLL /LTCG /CLRIMAGETYPE:IJW     /OUT:bar.dll *.obj

Extra: One can rename exported function names after cpp to obj compilation in the export directory to their liking :)
