Porting a Linux open source component to QNX

Porting an open source component from Linux to QNX requires careful adaptation due to differences in kernel architecture, system libraries, and toolchains. While both operating systems are POSIX-compliant, QNX’s microkernel design and real-time behavior introduce unique considerations, such as modified system calls, alternative libraries, and a specialized build environment. This chapter outlines key steps to ensure a smooth transition, covering toolchain setup, POSIX compliance checks, and QNX-specific optimizations. For deeper technical details, refer to the official QNX SDP 8.0 documentation.
