Can I install two or more versions of the XC8 compiler?

Yes, two or more versions of the MPLAB® XC8 compiler can be installed on the same machine. For example, you can have XC8 v1.10 and XC8 v1.20 compilers installed on your machine.

Compilers will be automatically installed into a directory that is specific to each compiler version. For example, under Windows® the XC8 v1.10 and XC8 v1.20 compilers would typically live in separate directories, such as:

  • C:\Program Files\Microchip\xc8\v1.10
  • C:\Program Files\Microchip\xc8\v1.20

To select which compiler will actually be used when building a project under MPLAB X IDE follow these steps:


Open a project in MPLAB X IDE.


Right-click on the project name.


Select Properties.


Under Compiler Toolchains, select the compiler version to use and press OK.
