Inline funtions (STL) not inlining

[=?Utf-8?B?TWljayBPJydOZWlsbA==?=]

I asked about this a few days ago, and not found an aswer yet, but I have
tracked down further info. I am getting the problems occrrung with the stl,
under thses sorts of circumstances:

#include "LibraryHeader.h"
#include <list>

namespace MyNamespace {
public ref MyClass {
public:
MyMethod() {
list<LibraryNamespace::LibraryObjectmyList;
....
}
};
}

What occurs is I end up with a link 2001 error, trying to reference the
list<LibraryNamespace::LibraryObjectconstructor. Note that the Library is
unmanaged code.

Could you please post the complete compiler error message?

ok: I am trying to wrap the ImageMagick library at the moment: Here is a
paste of the message (with the real function names)

error LNK2001: unresolved external symbol "public: void __thiscall

and the code causing it....

};

Does "LibraryHeader.h" contain a #pragma managed directive?

If not, you're probably ending up with an ODR violation with LibraryObject
being defined as both a CLR class and a native class - that could be the
source of your error. You might try:

#pragma managed (push, off)
#include "LibraryHeader.h"
#include <list>
#pragma managed (pop)

to see if that resolves the error.

Thanks Carl - something I hadn't thought of. However, just tried it, and
made no difference. I'll keep trying to find a work around. Maybe something
will click.

Hey everyone - I've figured it out. It has to do with the way the ImageMagick
headers builds the libraries and/or DLL's. Because I'm wrapping the whole
thing in a .NET assembly, but linking to the static ImageMagick libraries,
the Headers are getting confused, and thinking the assembly is a DLL build of
the library, and prefixing the declarations with a __declspec(dllexport),
effectively stopping the inlining.

Now I've figured out the "why", should be simple enough to stop it all.

Thanks for your help folks.
