I'm thinking - we need just such a list! I mean - the only info out there for Win98 users is confusing at best. What is needed is a VERY SIMPLE explanation - basically, several steps.

You are sooo smart. I am not sure I completely understand everything you have said in the last two posts, but if I just blindly type "make --unix" IT WORKS!!!. I will now go back and see if I can follow everything you have suggested and see if I can (...) (25 years ago, 27-Jun-99, to lugnet.robotics.rcx.legos)

(...) So is the idea that you might have a "shell" app that lets you control a button or two and that takes over the lcd at times (say), and lets you start, suspend, and stop other apps that control different, presumably disjoint sets of motors and (...)

(...) They could. In fact, there may be cases where that is exactly what you want to do. However, that requires you to write your code to examine the semaphore at every point where you would want to consider processing the event. It is more work. (...)

(...) Yes, that is it. A classic example is a full screen app such as vi. When being stopped, vi sets the terminal mode to something generic and saves any screen info that it needs. When resumed, it sets the terminal mode back to what it wants and (...) (25 years ago, 26-Jun-99, to lugnet.robotics.rcx.legos)

(...) Now keep in mind that this is coming from someone who won't take Duke's OS class until next spring- is there any reason the current semaphore implementation couldn't be used for a large percentage of these tasks? I.E., thread A checks (or uses (...) (25 years ago, 26-Jun-99, to lugnet.robotics.rcx.legos)

(...) Damn, I am too used to tcsh, and yet I still remembered the export. Make that: MAKE_MODE=UNIX; export MAKE_MODE (followed by make) Again, make --unix should also do the trick if that is easier to remember. Oh. My MAKE_MODE environment variable (...)

(...) What am I missing? Why do you need callbacks in the process structure? I was thinking if you can reference the thread, you can just call a system function (e.g. suspend(thread)), and that will suspend the thread. You do not need callbacks (...)

(...) Some versions of make look for the sh shell, others use the dos shell. Probably, make is using the dos shell and not sh. As far as I know, make does not parse the parens, the shell does. And dos does not understand the parens. My cygwin make (...) (25 years ago, 26-Jun-99, to lugnet.robotics.rcx.legos)

Thanks Lou, I am sure that you are right. I also don't know what could cause it or how to fix it. I just hope there is some bright person who reads this NG and can get me on to the next step.
