System: Ubuntu 18.04 I just went out and bought a new external Logitech webcam, and I am trying to make it the default webcam instead of my labtops intigrated webcam whenever it is present. For instance, if the cam is plugged in then it should be the default but if it's not plugged in then the...

Is there a way to access data that was set during startup from the user space? There is code in place for this embedded system that essentially probes a gpio pin to see if it's on the hardware. If it is on the hardware then it will set an int variable called value to 0. What I would like to do...

Ubuntu 16.04 I was attempting to build an old kernel today: 2.6.35.14 and I got an error: make -f scripts/Makefile.build obj=arch/arm/mm make -f scripts/Makefile.build obj=arch/arm/common make -f scripts/Makefile.build obj=arch/arm/mach-mx5 make -f scripts/Makefile.build obj=arch/arm/plat-mxc...

Any ideas about how I can be sure which files need to be altered? If you might be able to help but require more information just let me know. I have data sheets for both codecs and board specific information on hand. I also have circuit diagrams for how the CODECS are hooked up (old and new). I...

Thanks guys, yeah I tend to avoid just typing "good c++ editor" into google because the majority of the results are only going to be companies who have paid money for the advertisement. I am going to start off with visual studios because I like the idea of being able to look at the assembly and...

Hello, so currently to view and edit c++ files I am using gedit. It works okay but the problem is the lack of features. I am looking for an editor similar to notepad++ but for the Linux platform. I don't need anything too fancy. If I highlight some method definition I would like it to highlight...

A bit of an update: I found two guides: https://gcc.gnu.org/faq.html#multiple and http://www.tellurian.com.au/whitepapers/multiplegcc.php Interestingly, both guides refer to gcc being located in usr/local/gcc; however, on my machine there is no gcc director within local. I did find a directory...

Awesome, thank you Ryan you have been a great help!

Great, so what is lo: vs enp0s25? When I ran the command I got 1: lo: and 2: enp0s25

The version of Qt that I know works for sure is 4.7. So rather than force the application like Qt to compile with a certain compiler. I would just force my machine to compile with one or the other? That seems right here is what I got: murchrob@bznlinux038:~$ file $(which g++) /usr/bin/g++...

Can someone explain to me the difference between the: inet addr: i can find thorough an ifconfig and a LAN address? It seems to me that my LAN address is just my inet addr: with a /extension on it is that correct? Is there a way to figure out what my LAN address is in linux? It was already given...

So this is just a DOS version of a shell script then? Apparently, the person who asked thought I was on a DOS system?

To be honest, I am not the most competent Unix user in the box. If I tried installing it along with 8.1 how might I direct a program like Qt to use the version 4.7 rather than the 8.1?

Is downgrading my gcc from 8.1 all the way to 4.7 going to be possible? Would it be as easy as: apt-get remove gcc-8.1.0 apt-get install gcc-4.7 Or am I going to run into unforeseen complications if I try to do that?

I was recently asked to "post a batch file/script that would run the configure and build exactly as you do, on a clean command prompt, in order to reproduce your issue" what does this mean in layman's terms? What is a batch file/script?
