Welcome! I post videos that help you learn to program and become a more confident software developer. I cover beginner-to-advanced systems topics ranging from network programming, threads, processes, operating systems, embedded systems and others. My goal is to help you get under-the-hood and better understand how computers work and how you can use them to become stronger students and more capable professional developers.
About me: I'm a computer scientist, electrical engineer, researcher, and teacher. I specialize in embedded systems, mobile computing, sensor networks, and the Internet of Things. I teach systems and networking courses at Clemson University, where I also lead the PERSIST research lab.

Didn't know you had a youtube channel! You were my professor for Operating systems at Clemson
Cool. Welcome to the channel. Hope things have gone well post-Clemson.
@@JacobSorber Where is your whole entire complete full course on Operating Systems? Do you teach Windows Kernel Mode Programming?
These are the best videos on C I have come across on youtube would recommend 10 / 10
@Carmelo Bruce nice I will keep that in mind, ty
Long ago, a clever co-worker on a resource starved system used for lots of text processing implemented a "spell checker" using make. Unique words were pulled from a file, the list sorted, then words were tested to exist in a dictionary. Finally, remaining unknown words were left for the user to find and correct in documents. (I should clarify that this system had virtual memory to swap in/out of its 512kb of core RAM...) I recall there were other features to his makefiles, perhaps something like building a TOC or index, too... Long, long ago...
Thank you for making this video, it answered questions and had suggestions I haven't been able to find anywhere else.
Your welcome. Glad it helped.
i realize it is quite off topic but do anybody know of a good website to watch newly released movies online ?
@@bentleydarwin7979 You can typically buy them from iTunes pretty quickly after release
Holy shit thank you for making that distiction about the toolchain! I had heard that term being used many times and I never understood what it meant. I of course knew what a compiler was, but did not realize that the actual act of taking code to executable was an act not just by the compiler, but by multiple tools in a row; a toolchain. This video was worth it just to learn that, thank you!
As a small and flexible tool,make is a really efficient one.I have read that it can be used in automating various processes.According to you,where do you think it would be best to use it ?
Wow half an hour to compile a C program
Hmmm that must be a pretty big program
C rocks !!
Props to linus torvaldz
What a great video! Thanks for this!
Thanks a great deal
This video really helped me
Not even 2 Minutes and I already understood what a toolchain is
Can you kindly do a video on linker scripts? How the memory mapping works. Thanks.
Does someone know what icons extension he uses? I'd like my .h files to have this purple C but I didn't find one that does it yet
And if my program has got multiple programming languages
then you probably just use a shell script
Nice video! Do you ever use CMake?
Thank you sir:)
How to compose multifile universal makefile?
Nice video, but man, I slowed your video and it is still fast in some parts! Nice work
I learned a lot...keep making videos
thanks for this great video
Welcome.
your videos are great, but there is only so much that can be included in a TH-cam video before it becomes to 'dry'. i am reviewing " The GNU Make Manual". is there any resources you could recommend on make that is somewhere between the details in the make manual and the easy of learning of your videos? I tend to use bash build scripts but the versatility in using make is appealing. thank you
compiler has many stages like semantic analysis
Can anyone help me with makefile with multiple subfolders and files
Isn't compiling multiple files at the same time the purpose of a makefile?
Yes. That's usually what we use Makefiles for.
Ha! I can compile a kernel in a half hour these days? used to take 3-4 hours on my 486!
what compiler you used ?
How can a makefile be used for a project containing both C and C++ source files?
Make doesn't really care what language you're using. So, you can just put in separate rules for your C and C++ sources. Linking them together can sometimes be a little tricky. Not a bad idea for a future video.
what softwear do you use for writing your code and compilning it ?
i think he uses Atom code editor and Clang compiler
Hey, I want to generate .so files for multiple .c files that are saved in a directory so that I can use these .so files in a Python code. Is there a way to do that?
I need to have a constant, LDFLAGS = -lpthread
But when I put it into my rule for main:
main.o: main.c
$(CC) $(CFLAGS) $(LDFLAGS) -c main.c -DUSE_PROCS
It trieds to do: clang -Wall -Wpedantic -Wextra -Werror -g -lpthread -c -main.c -DUSE_PROCS
And gives error: -lpthread: 'linker' input unused.
I can compile it without the -c method just fine.
With -c, you're just compiling, not linking. So, it produces a warning that the linker-specific input isn't used. -Werror tells it to treat all warnings as errors. So, that's why the error is there.I would just save the LDFLAGS for the linking step.
You sound *exactly* like The Modest Man.... 🤔
You think so? Hmmm...
