In other words pthread_create() is supported, but not fork() or execve(). If you need multiple processes then you will need an OS that supports higher levels of EL/IX, for example some embedded Linux variant. Similarly, if you want to develop an application for Linux with the eventual goal of porting it to eCos, you need to restrict yourself to the appropriate level of EL/IX functionality. Bart
