Compiler is simply complaining about a build time dependency, cc1 tool should be in your system to build pyodbc.

In Ubuntu you can solve this with

This might not be your only problem but you have a race condition that could show up if you pause and resume quickly (where the definition of quickly varies greatly depending on your circumstances). Consider that you've got 32 threads each requesting a MB chunk, let's call them threads 0-31. They are sitting their downloading and you pause. The threads do not know that you paused until they get a chunk of data as they are sitting in blocking io. Not sure what speed your connection is or how many cores your machine has (threads will sometimes act in parallel when they don't need the GIL,) but this process could take a lot longer than you expect. Then you unpause and your code creates new threads 32-63 but some or all of threads 0-31 are still waiting for the next chunk. You set threads 32-63 in motion and then you turn off your pause flag. Those threads that didn't end from 0-31 then wake up and see that things aren't paused. Now you have multiple threads accessing the same state variables

What i did is to wrap your everything in a div.(class mapBg , you can chose better name) the div is with the size we want the map to be, the map img is getting width: 100% and height 100%. then the pings can be position absolute, the top and left will refer to the limits of the wrapper div. here is an example.

I tried to create a scheme to organize by "run position" and it works. Follow my code.
