[Wine] USB connection problem, home made code

[Rorke]

My workmate made a XP PC program that talks to a motor through a USB.
I've made a link to USB
ln -s /dev/ttyUSB2 ~/.wine/com2

and also 4 of

ln -s /dev/ttyUSB1 ~/.wine/dosdevices/com2

as recommended in a forum.

I don't understand how to 'make' wine-git. The Makefile errors, but I've never successfully compiled anything for Linux, so I don't suppose I did it right. (Is there a 'point and click' repository I can get it from?)

Any thoughts, or is this going to be too complex for a Wine noob like me?
