Sorry for the long wait. Last friday we’ve published a new version of CircuitBlocks that adds Spencer programming and also resolves a lot of issues that were occurring in the installation process. You can download the newest version from https://circuitmess.com/circuitblocks/download/
If you have canceled the installation process at some point, and compiling/uploading sketches doesn’t work, please install the newest version of CB, delete the directory /Users/(username)/Library/Arduino15 on Mac, C:\Users(username)\AppData\Local\Arduino15 on Window, or ~/.arduino15 on Linux. The next time you start CircuitBlocks, the files that were previously corrupt will install again and everything should work. Please note that this process can take up to 10 minutes, depending on your internet connection. If it hangs indefinitely, please contact us at [email protected] so we can resolve the issue.
I have also compiled the Linux version against glibc 2.27, so it should work on Ubuntu 18.04 onwards, and Mint 20. These are the distros I’m 100% positive that work, but every other distro with glibc 2.27 or newer will work too.
Let us know if you get any other issues, and I’ll make sure we fix it for the next release.
