Linking with static dcmdata/ofst lib from a .Net application

[Prash]

Hi,

I recently attempted to build a simple forms application in Visual
Studio 2005 (Express) C++ edition. I built dcmtk package myself, as a
collection of static C++ libs. I then link with these libs from the
managed C++ forms application. Everything compiles fine, links great.
But there is a runtime access violation thrown as soon as the first
const is declared in a dcmtk file:

const OFConditionConst ECC_Normal( 0, 0, OF_ok,
"Normal");

I suspect it is because of mixing of unmanaged and managed C++ code. I did see similar posting earlier in the forum, relating to similar problems; but none of them discussed specific remedies.

If you have any expertise in this, please share.

FYI:

[1] All projects are built with /clr option and multithreaded dll
support, except dcmtk: multithreaded dll, but no clr. It wouldnt link
properly if built with /clr option.

[2] The application runs fine in release build, the access violation is in debug build.

Ok I found the fix. Apparently this is a known issue in VC2005 express
edition, so when using a static constructor in unmanaged code with a
managed forms application, the entry point of the managed app should
not be 'main'. Here is the link to the angelic description (I tried,
works like magic:-)

Another reason I dont like Microsoft - they market more than they
perfect their products!


Thanks all anyways,

Hi Prash,

thanks for sharing your solution

Did you already take a look at the clearcanvas project who built a NET wrapper around parts of DCMTK? I am not sure whether this is of any interest for you but maybe it could be interesting for the future.

Michael

Thank you Michael.

For now, I am only mending a small hobby project, mostly to learn as I go. I will definitely keep ClearCanvas in mind.
