Dependency mapping
Create a comprehensive dependency matrix for example:
| Dependency Type | Linux Standard | QNX Equivalent | Porting Strategy |
|---|---|---|---|
| C Library | glibc | QNX libc | Patch GNU extensions |
| Threading | pthreads (POSIX threads) | QNX pthreads | Adjust scheduler policies |
| IPC | Unix sockets | MsgSend()/MsgReceive() | Rewrite communication layer |
| Event Handling | epoll() | poll() + ionotify() | State tracking needed |
