From the GUI-based installation manager I selected everything and installed it. Unfortunately I don’t see lex/yacc, nor bison/flex.
Do these exist for QNX?

flex/bison are in /usr/bin on my installation.
I finally located them, and they are in a rather strange place:
/usr/qnx630/host/qnx6/x86/usr/bin
Strange place to put them. Had to insert my own PATH to make them work.
If you are installed properly, you should find them. This is related to the post about not being able to compile with bash and /etc/profile not being run.
