If compile time is an essential part of the build time, then you are making a program.
You are not making a software system composed of sevearal program components merged into a whole.
You are not making a software product with nasty elements such as documentation, test logs, ...
Or, maybe you are, but when you say "build time" you are not talking of building the software system product, but to "build" a linkable unit from a source file. Then you might see compiling filling a noticeable part of the build time. Maybe half a second out of two seconds build time ...
Last time I did a make clean, rebuilt the system from scratch, and inspected the last written timestamp on the compiled files, there were typically six to eight of them completed per second. (And last time I did this little exercise was around ten years ago; we've got faster machines today.)
Using compile time as an argument against compiled languages, in favor of interpreted ones, might have been valid in the 1980s. It is not today.
Besides: Because interpreted languages traditionally had lousy run time performance, all major interpreted languages today start the interpretation by doing an on-the-fly compilation... (if they do not find an already compiled version in a cache). So you don't escape the compile time - you just count it as part of the run time.
First, you should learn to consider that someone might be joking. This is the lounge.
Secondly, when I think build I think of the entire thing. Compile and link.
If you use second-party libraries for much of your source the it will be much quicker than it really should be. Mostly, what I did I built from scratch. An exception to this was the .lib file that came with an A/D converter. For FORTRAN, years ago, I even built a graphics .lib I coded in Assembler. The whole thing, if I did it all at once, would be done in a minute, tops (on an 80286 w/HDD and 1 MB RAM).
Mostly, however, the libraries were compiled once and, with the exception of an occasional addition, left as they were. Compile/link took seconds, usually.
You need to get a grasp on context when commenting in the forum. Not every, and perhaps hardly anything, is taken seriously. Certainly not if there's an opening for a laugh. Maybe that long sunless winter's getting to you?
Well, back when it was Turbo Pascal: Used the bathroom (took a book), got a cup of coffee, chatted up the receptionist (you could do that, then), checked the telex machine, read a bit of Byte magazine and then topped off my coffee again.
Some microcontrollers do not have RTC support or any other kind of timer-like tick coming in so cooperation seems like the best option for them. I seem to remember an article or two here on that topic.
I've also found that introducing multithreading into a system you already can't debug using a traditional debugger is a recipe for a nightmare in practice.
What I've done on this dual core monster I am working with is I keep exactly two threads - each with its own core affinity, and they basically do very little communication with each other, and all of their work is internally cooperatively multitasked.
It doesn't have an RTC per se, but like most CPUs it has a timing crystal connected so you can get the number of milliseconds since boot with it. I use that to make timers.
I have a similar issue. I have a big bunch of code to debug that needs to run on a GPU. I have written it so it can also run on the CPU so I am doing all my initial debugging on the CPU and then I'll try it on the GPU. I have already tried small bits on the GPU and it looks good so far.
