Making a DLL

[wajih boukaram]

Hello I need to write a DLL for some functions that I have which depend on a separate lib file. when i write a short test program that uses the functions as is and link against the lib file, everything works great. But when i take the same functions and put them in a DLL, it doesn't work (i get some unresolved references to any function that I use from the lib file). Am i supposed to do anything special to get it to recognize the functions from the lib? thanks for your time.

effectively, there are some things to get done for a DLL to work properly. you should start by reading this[^] article...

yeah i already know that bit when i have regular functions that don't depend on the library (the one that I didn't write) the dll builds just fine it's when i use the library's functions in my dll that i get the linking errors.

You haven't specified what type of DLL you're using or how you are linking and/or binding to the DLL at runtime so it's difficult to give a specific answer. I do know you will find links to a solution here[^] If I had to guess, I'd say you need to link your application project to the link library produces by a build of the DLL project, but again, this is a wild guess since you gave no specifics.
