This suggests you are building for a Spark Core and not for Electron.
If you tell us how you build we might be able to advise you how to actually target an Electron

You’r right, I had the core selected. I’m on the web IDE. Changing to electron sorted it out but the error message didn’t really hint towards that.

It might not have been obvious, but since I only had to see that one -DSTM32F10X_MD switch to actually see the reason, all the hints were there.
After all, this was a link error and not a compile error there isn't much more to hint since the code itself did compile just fine (only ignorable warnings) but the actual reason for the failure was that the Core has too little flash memory to hold the resulting binary.

If the result would have been that fraction smaller, the build would probably have succeeded giving you a valid Spark Core binary. How would the IDE know that's not what you want if you didn't tell it the same by actually selecting the correct target.

If you look at the status bar at the bottom of Web IDE you'd see what Web IDE knows about your intended target

Yep good point. I didn’t notice the little yellow or red icons so much.
