HI dear author,
It's truly a honor to write a letter to you, I'm building your project nowadays and found the error when building as following, I wonder if there is a chance that you know the reason? :)

thank you
best regards to you

The error meant that g++-6 was not installed on your system. Although I had hard-coded the command g++-6 in the script, it doesn't make sense to specify the version of g++ in this way. Also, g++-6 is outdated nowadays.
I just updated run_8cc.py, so please pull the change and try it again.
