Hi everyone, this is my first post to this forum, so please forgive any errors on my part...

I'm working with BCI2000v3, and I'm adding a new data input ("SignalSource") module for some new hardware we recently bought. (The hardware is a Trigno EMG system from Delsys.) I think I just about have everything in order for it to compile, but I'm getting one persistent error that is preventing it from compiling. Here is the error that I'm getting:

error LNK2019: unresolved external symbol _WinMain@16 referenced in function ___tmainCRTStartup MSVCRT.lib TrignoSource

I can't seem to figure out this one despite a lot of help on the forum for other "unresolved external" errors, but those posts seem to be dealing with Qt issues, and this seems like it might be a larger Windows issue with BCI2000.

Any help is great, thanks!

FYI if it helps: Qt version is 4.8.5

I actually figured out that this is a bug that results from using an old version of BCI2000. If you get this error, you need to add a .cpp file to your source module. Give it a name like SourceSignalClient.cpp. It should have the following code within:
