# Building sample applications on POSIX with Autotools fails ## Problem environment The firmware development environment is portable, allowing the user to build sample applications on POSIX operating systems with GNU Autotools. ## Steps to reproduce 1. Refer to firmware 1. Build using Autotools ## Expected result Building sample applications on POSIX with Autotools succeeds. ## Actual result Building sample applications on POSIX with Autotools fails. ## Workaround Use the Microsoft Visual Studio derived Microchip Studio product on a supported Windows operating system, ignoring POSIX standards and GNU Autotools build configuration. ## Severity level This is **low priority** because project requirements do not mandate source code portability.
