Another pro to Dynamic Libraries is that they are Shared Libraries. If you have 80 different applications that depend on the dynamic library, they all call the same DLL at run time. They are SHARING the library. You do not have duplication of the library's code, and each executable only contains it's own code. This is why Dynamic Libraries are called Shared Libraries.
thank you master
You might've done this 6 years ago, but this is so well explained. You've just earned one more subscriber.
Keep making the tech videos for noob like me. much appreciated
+1 noob
Hands down best explanation of static and shared libraries. I much needed this video as I was struggling to understand this concepts.
You making this specific video is a good example of why the internet is so great! Thank you, glad you decided to talk about this. I've seen .dll files many times over the years, never knew (nor was curious to know) what they were.
You explained this topic beautifully, very clear and precise. Thanks Dave.
Hey Dave, I hope you can keep making these tech videos. I played this video during one of my college's C# classes, and everyone in the class loved it. Hope you can keep making more, they're super useful and will make for a wonderful reference in the future to come back to!
Nice! haha wow that's cool. Yea, I haven't made a technical video in awhile, I'll have to make one
Man, don't care too much about views for any given video. Technical videos are much appreciated and you help a lot of people.
This is the best explanation ive come across so far. Thanks!
So who told you your videos on tech are shitty? This is the information I've spent close to 72 hours sourcing for. Great job!
you are so good at explaining things！thanks Dave
Just to sum up using code:
file.c
#include
int main(){
printf("Hello");
}
If we compile this file using gcc then there are two ways either we use shared library to include printf() functionality or we use static library which include whole other bunch of function along with pritnf() which make our executable heavy...
Simplely compile your above program in two ways:
gcc -o output file.c
gcc -o output2 -static file1.c
And check the size of output and output2. Since output2 is statically compiled it size is greater then output file.
I started watching your videos on sunday morning, when I was hungover ... that day changed my life... 😊
Dave! You should keep making the tech videos. The simplicity of your explanation is splendid.
Real good stuff! Feels good to get the feel of how things work under the hood in general. Keep more such videos coming!
You have a really good accent. Simple and strait forward, Keep making tech videos for us! lol!!
I love how much easy you made understanding this concept. God bless you
Subscribed! You are better at explaining these concepts than any professor I've ever had.
Really dig your style of explanation. So calm and measured. I understood all of it. Thanks!
Keep making the tech vids. We love it
Great video. I now understand static and shared libraries more vividly. Thank you.
I really love this video! Detailed explanation, you broke things down to the core.
Thank you very much😃, I really enjoyed it👍
10 minutes well spent thanks buddy
Extremely thankful to you Dave!!...You explained such a complex things in such an easygoing way..keep making the tech videos🔥
I agree
This video is 7 years old and it aged so well even now
This explanation was pretty much perfect. Thank you!
As a typical highly interested in the why of stuff. I was looking in my systems and was like ..shared storage my ass... then I cancel the clear data . I came to this and wow. You do really great at teaching. I am not in this field of expertise but l can say this...I understand a whole lot more about my phone now.
You guys use us being connected so we help give strength to the core of this huge web of shared storage...interesting.
That's kind of cool .
what programming or developing... I think this was a good video. Dont ever give up or not do your desire. Tech is in need of your communication style. Keep up on this stuff.
Very good and simple explanation. Easy to understand.
Your explanation about compile time versus run time loading of static library and shared library, respectively, was good.
Thanks for making this, very useful. We need more fundamentals like this
Really good and simpler explanation. Thank you so much for this video. Subscribed !
Me caiste bien amigo.
Explicas de una manera espectacular, seguire viendo todos tus videos.
Gracias
Great way of explaining it, thanks for video!
dave Xiang is the man!!!! your videos are helping
Thanks Dave Xiang - very good explanation .
Outstanding Explanation Dave Xiang..
Thank you! This is a great supplementary video to LFS201.
You explain things very well!
Thank you for explaining this so well.
Thank you for this video, you explained chapter 1 of my linux+ book very well!
Great video man, brilliant tone and explanation flow.
Thank you so much for the introduction.
You explained that very well. Thanks!
Thank you for another great video Dave. Keep´em coming :)
Cool explanation, thank you very much!
this has helped me so much! thank you! really appreciate it.
Thanks Very much for this talk on libraries - you have touched on some cool points.
thank you so much for those explanations. subbed!!!
Very well explained. Thanks a lot!
Learnt great stuff from your video that I was not able to answer in one of my interview and failed.. Thanks alot for such kind of stuff :)
I'm not learning any C-like languages (yet), but this helped me better understand what's going on when I have dependency issues of any sort, whether it's managing language versions, getting frameworks up and running, linux stuff, etc. This also clarified some differences between "compile-time" and "runtime". Thx!
+James Gaehring glad it was helpful! thx
David, Im extremely grateful for what youre doing here for the newbie community. im about to undergo a web app development curriculum that stresses a slow path.. and their language of choice to teach is Ruby. do you have any opinions about Ruby as a first language?
Ruby is a good first language for sure. Easy to write, easy to understand. Also, very popular with web programming.
Hello , I know it's been 7 YEARS, but in the Event that you see this, how did that curriculum workout for you?
Thanks for the video, it's very educational! I also laughed a little when you told us about how you messed with some of the .dll files on your computer can bricked it as I also did that when I was a kid (was my first time seeing a blue screen).
very well explained, thank you very much.
great conceptual explanation of it!
Yeah Thank you, this is very concise explanation and cleared my doubts, which I didn't know to form a query to Google search.
excellent tutorials....i just love it...keep it up
Excellent explanation.
Great explanation. Thanks for sharing!
Thanks man, keep up the good work!
I use static libraries when there is less duplicated code to not worry about run time dependencies, but if I have some code that most of the rest of my project(s) need, I bung it in a shared library.
0:09 my 2¢: don't worry too much about "doing well" with likes/views. Online approval can be misleading. This is a quality topic
Thanks Dave!
Super helpful. Thanks man!
Very nice video.. Tech videos rock!
Great video, i understand clearly
really solid explanation!
yes ! for me very helpful and understandable video.. thank you for sharing ...
that was a very good explanation.
Thanks a lot for this !
I finally found you - - This is really good
It's a nice overview about these types of libraries, but you tend to repeat your structure sometimes.
Great Video!!! Thank you, keep on please
Great explanation man, thank you
Thanks for the great videos. Your videos gave a clear picture of what's going on under the hood..
Can you please make a video on how linkers work, what are relocatable object codes and some info on symbol table in context of C program compilation.
Awesome .... thankyou so much
THANK YOU!
very informative thanks a lot.
Thanks for the video
I REALLY like the tech videos.
keep making tech videos :) & thanks for helping me
thank you.. learnt alot ❣️
Awesome, Thanks
awesomeness ... 👌👌👌👌 please continue making these tech videos... I'm finally understanding coding ..... thanks a lot !! please do complete tutorials on c# ....
Thanks! this is helpful
dang! that's a headshot of explanation!
Subscribed after this
Thank you
Although I might be wrong, but actually there is small mistake in your explanation. All the executable code or implementation of functions in particular library (at least in case C and C++) lies in DLL files. Bit in static linking of library in time of compilation a .lib file is used to find a needed function in DLL file, while in dynamic linking the process differs and a .lib file is not needed.
So .lib files are for the static linking, but the actual code of library are contained in dll file in both cases.
Its info on WIki:
en.wikipedia.org/wiki/Dynamic-link_library
Thank you!!!
really help me thanks
good explanation, keep it up!
thank you
+Dave Xiang I've recently discovered you channel, and I think it's one of the best of its genre. Thanks a lot for all the knowledge! I would really like if you could answer one question I have: I'm currently learning C (as a first language) on Linux, and I'm reading Stephen Prata's C primer plus. Should I continue reading it, or do you recommend me another book/course?
+Lucio Cardoso Nice! C is an ambitious language to learn first but should be fruitful once you understand it. I don't know about that book personally, but just make sure you can differentiate from a "reference" style vs "curriculum" style book. I would get one for each. A curriculum you can easily follow, and a reference which you can index for specifics.
Really it's simply an awesome stuff..
Thank you man.
Jus another Gold Video:)
Really helpful , Thanks :)
Well explained
amaaaaaaaaaaaazing thx dave !!!!
