I have a VI in LabVIEW 2011 in Windows XP and I want to know is that possible to convert it to LabVIEW in Linux with some little changes? If yes which version of LabVIEW in Linux should I have?
The success of your conversion will depend on what functions you used. The are many that are windows only. These are noted in the help. Certain hardware drivers are not portable. What are you using?
