Error due compilation

PlatformIO Core
1

LinuxMint20 OS

I am trying to compile Marlin 2.0 firmware for a 3D printer. I do this with the console command $ platformio run.
An error appears while executing the command. From the output I can not understand what is the reason. Please help me figure it out.

The variables maxj and axis are unknown in this section of the code. That’s exactly what the compiler is telling you.

Either you are not compiling the latest Marlin version, you have wrong configuration files, or Marlin has a bug. Either way, the people you want to talk to is the people who write the Marlin firmware, not the people that make the build system. See Issues · MarlinFirmware/Marlin · GitHub

Thanks for the answer. The reason I wrote here is because I have already compiled this version of marlin, there were no errors. Only two things have changed: I replaced the LinuxMint18 operating system with Mint20 (and, as a result, the PlatformIO version) and made changes to the marlin configuration file. Now I’m trying to understand what caused the error.

Do you have a backup of that old file? Did you change anything regarding Axis settings (max jerk)?

Unfortunately, the previous version of the file has not survived. I will look for the source of the error. Thanks for the suggestions.
