How do I properly build a dll in cygwin (gcc) that can be loaded through Labview 5

[jgall]

I am a newbie to building dlls as well as to cygwin. I realize that this is more a cygwin/gcc dll build question, but I have built a dll (using cygwin) that can only be accessed by running an executable through cygwin. When I try accessing a function in the dll through labview, I keep getting a "function not found" error, even though the parameters etc are correctly passed.

If anyone has built a dll through cygwin (and has had success using it through Labview), I would appreciate directions on how to do so properly.

Thank you in advance.

Yes, this is a cygwin support question, so I won't be able to help you much from the LabVIEW side. Just make sure you follow the instructions in Using External Code in LabVIEW manual on gcc compiler.
