>using IDE for learning
Seriously why do normalfags do this? I bet half of class doesn't understand the difference between IDE and compiler. Professor is right. Stop complaining and port code to UNIX. And no hardware can't prevent you from installing a new OS? Ever heard of virtualization?

>>60141665
There's no excuse, since many Unix systems are open source, therefore being free, and therefore running on nearly any hardware architecture possible. Too bad, bro, but it's all your fault.
If your computer can run Windows it can run FreeBSD.

>>60141665
Like you haven't even said what language you're using (likely either C or C++ but still). Do you even know if your code is platform dependent? If it's just using standard libraries it probably won't be.

that would be fucking retarded. *nix OSs run on fucking everything while windows is limited in hardware support.

Should have used libraries instead of writing those yourself.

I had a professor who required we learn both g++ and msvc++; our code projects had to compile with both compilers.
We were even required to write our own makefiles and give compile instructons when we "turned it in" for a grade.
I HATED it at first. But halfway through the course I saw the wisdom of it and stopped being a little bitch about it. Your professor wants you to learn these things so you aren't boxed in to using windows for the rest of your life. If your code doesn't need platform specific code, you should not write platform specific code initially. For very large projects, you want as much of your code to be portable as reasonably possible (hopefully not at the cost of performance or functionality). Your professor probably gave you an assignment which they knew could be coded in a platform independent manner.

>One of my control theory courses has a pretty assburger prof who insists we use UNIX-based systems in a code project.
Which makes sense considering that UNIX and UNIX-like families of OSes are far better suited for the job and far easier to use than Microsoft Windows in this particular context. There is more documentation and examples available and just truck loads worth insanely good books. You should install Open/Net/Free/*BSD, Solaris or (some UNIX-like such as) your favourite GNU/Linux distribution (such as Fedora, Debian or Slackware).

>Still half the class, including me, went with using Visual Studio as an IDE instead.
Why on earth would you guys do that? You're not learning anything that way. Especially if the language is C. The MSVC isn't even fully C99 compatible (let alone C11).

Introduce yourself to Bash, Vim, GCC and Make.

>The deadline is next week and my entire project is written for a windows system.
Well, I guess it's time for you to learn POSIX and write universally compatible programs. The problems you mentioned are fairly easy to solve. For example sleep() being in microseconds on Windows and seconds in POSIX is solved using nanosleep().

>What's a good excuse for not having used UNIX?
In this programming context there aren't any good excuses. You could try building an argument using the "UNIX-Haters Handbook" but that's mostly invalidated by the fact that the book is outdated as fuck. It's still amusing to read though.

>Could I blame it on compability issues with my hardware preventing installation of a new OS?
Nope. Modern UNIX systems like *BSD and Solaris work pretty much everywhere. Furthermore GNU/Linux (which is a UNIX-like to be precise) has a far better hardware compatibility out of box than Microsoft Windows. You guys could have even used macOS (which is a one kind of UNIX) for this task and still come out as winners.

Blame it on the jews

>>60143952
>The MSVC isn't even fully C99 compatible
seriously ? i'm too lazy to look it up, but thats kinda hard to believe, even if it's m$

>>60141665
Just install a VM and compile it there.

If you use compatibility as an excuse he'll just think you are a moron.

>>60144066
It isn't even C89 compatible. fopen is broken by design, to prevent code monkeys to do portable code.

>>60144086
fuck, thats really messed up. now i start to understand why windows users use mingw or cygwin or stuff like that.

>>60144066
However it's true. Microsoft doesn't care about the C language. They're only supporting it as a part of the C++ and the latest C++ standard supported by MSVC is C++11 which isn't fully C99 or C11 compliant. If you want C99 on Windows you have to use something like Pelles C.

https://en.wikipedia.org/wiki/C99#Implementations

And when people ask for the support Microsoft promptly usually declines...

Your professor likely uses Unix systems to test your code, and therefore, it makes sense to write code on a Unix system to avoid incompatibilities with the test script. If you're insisting on using Visual Studio and Windows-specific system functions, knowing full well that they will not work on the professor's machine, YOU'RE the autistic one.

>>60143464

It's not wholly wrong. The CL compiler will adopt a few C++ isms when compiling C code, like bitching about implicit conversions that gcc will have no problem with, but g++ will obviously have problems with.

>>60144548

To be fair, MinGW literally links everything against msvcrt.dll. So while it may do everything language specific perfectly (because it's literally just gcc for Windows), everything library specific is fucked by Microsoft. It really would be better to just ship their own libc and stop using msvcrt.dll entirely, although that would mean that they'd have to ship said libc with every application, just like with c++ programs produced with MinGW.

Got it running now! Thanks for the help anyway.

New problem; the code counts time way differently than the windows code. Below is an excerpt from a while loop.

        clock_t timeAtStart = clock();
                usleep(2000000);
                clock_t curTime = clock();
        runTime= (double)(curTime - timeAtStart ) / CLOCKS_PER_SEC;
                printf("%f\n", runTime);

This leaves a 2 second delay between the iterations in realtime, but when printed to terminal by printf it displays as in the screenshot. It's supposed to be like 0, 2, 4, 6 instead of 0.110, 0.113, 0.118 etc.

you aren't checking the return value of usleep, If it returns -1, you need to check errno. On some systems, the value passed in to usleep needs to be smaller than 1000000 (errno would tell you if that's the case for your system).
