I made a DLL using DEV C++ ad all other C++'s i could find

but when i call em from darkbasic pro or the other it returns a lovely "the DLL file failed to execute" error
same in other lnguage i tried to run my DLL in this is getting frustrating it wont run my functions..

it wont even run the samples i compiled in from the extra's folders. But everyone says this compilier orks "and im NOT going to get delphi or visual c++" i have too many C++ compiliers as it is.

Ive seen them work when other people mae em maybe im not doing something right.

Dont know anything about DEV C, so the following is only a guess : Does your DLL has the DLLMAIN function ?

Good news everybody! I really am THAT good...

I don't use it either, but I do know that Dev-C++ uses the mingw compiler. Have a look here http://www.mingw.org/mingwfaq.shtml. There is a section there for creating a DLL for MSVC.

Ah is DLLMain like the Main in C++? Remember now iim back from the day of DOS C++ Its easy to overlook something like that

Here's a skeleton of DLL main striaght from VC++

BOOL APIENTRY DllMain( HANDLE Module, DWORD Reason, LPVOID Reserved )
{
switch(Reason) {
case DLL_PROCESS_ATTACH:
break;
case DLL_THREAD_ATTACH:
break;
case DLL_THREAD_DETACH:
break;
case DLL_PROCESS_DETACH:
break;
}
return TRUE;
}

I don't know whether just defining it will allow your DLL to work, or whether you will need to specifiy extra compiler or linker options.

Also, which version of Dev-C++ are you using? I can download whichever one you are using and try some stuff myself ( Broadband )

As mrTAToad said, you need to export your functions. I prefer the following way. I have tested and compiled under Dev-C++5(gcc2.95).



And here is the test code


Enjoy!
