I have been writing the python script in for Wireless Temperature sensor which is easy to convert in executable files for OS Windows, Linux, MAC but every OS contains different software executable file formats to run the monitoring system software.
But I am looking for a solution which helps to run single software to run in different OS with only one file software file format.
You can't. The architecture of each are different. If it could be done, don't you think the BIG software makers would already do this?
If you are really concerned, make it run in a browser, that way all can run it. Easiest solution!
