Re: dll (probably newbie) issue.

Okay. Odd things are happening, well at least odd to me.
I built qeuti.dll using the Microsoft Visual CPP compiler, but initially forgot to add __declspec(dllexport) to the function definition in my header file. This resulted in a dll that did not have the external function exposed, of course, but what is odd is that Euphoria (now 64-bit Euphoria with 64-bit dll) successfully opened the dll in this state.
Later, when I added the __declspec(dllexport), the function was exposed, but Euphoria once again could not open the dll. What am I missing here?
not sure if this is exactly the problem reported, a problem is that Qt is c++ so you can't directly link to call routines. euqt is a wrapper for Qt started by Jeremy that creates a shim wrapper. you link to it, then the wrapper links to Qt.
- assuming you have written a shim dll, I haven't tried using MSVC compiler build of the euqt shim yet but I am not sure if that would be able to work properly, especially for translation. there is a problem with Qt using different compilers than the one the lib was built with. do a search if you are curious. quite the nightmare, though Qt itself is forward and backward compatible to an extent. you have to recompile Qt or use the proper compiler.
- I was just looking for a new build last night, there are 64bit builds of Qt using various minGW compilers here: http://win-builds.org/ and http://sourceforge.net/projects/mingwbuilds/
which version of Qt?
