I am trying to compile a program(in OpenGL) in Ubuntu, but I am receiving this error
fatal error: common.h: No such file or directory
I am not sure on which package I need to install for this.

common.h is not part of any package. I suspect you took the code out of some project or a tutorial that was part of a whole set of programs. And common.h is a header common to all those projects.

If you arrive at this page, it's possibly because your going through the 'Introduction to Operating Systems' book and tried to copy the code from the intro chapter directly and compile. At least, that's why I ended up here. This won't work, and will throw the above error.
It's best to download the code directly from the source and compile what they give you. Enjoy!

The CPR lib is well installed using vcpkg however the including doesn't seem to work:
#include <cpr/cpr.h>
So in the compiler (G++) it says "no such file or directory".
I tried to copy the include folder in my sources folder and call the cpr.h file, it kinda worked but I needed to call api.h and then async.h etc which didn't work.

I am a beginner to Windows API, and trying to learn how to make applications and such. I got to this part in the winprog.org articles, where the author started using resource files. I have written the resource file, in the .rc format. I compile it using the rc command, and it compiles into a .res file. Then I pass it off to the linker along with the the main object file, again, all from the command line. But when I run the linked executable, it does not show me the menu I defined in the resource file. Nor the icon I specified in there.
I am using Visual Studio Code instead of Visual Studio, partly to get comfortable with the MSVC CLI, and partly because I just like VSCode better. I also don't want to install additional C/C++ compilers when I already have MSVC.
So,
How should I go about compiling and linking the resource file correctly?
Are there any more up-to-date and not nightmarish methods to learn how to work with the Windows API?
You compile the resource script using the Resource Compiler (rc.exe) and pass its output on to the linker. There is no other magic involved.

I'm using Eclipse IDE but there is a linking error while trying to build the project without a main.cpp file.
I know that what i'm trying to do is possible because the HelloWorld example has its main() method inside HelloWorld.cpp but i can't find what i need to change inside the eclipse IDE project building parameters.
That being said, is there any drawback in having the main() method in a file different than main.cpp in one project?
Thanks
Edit: After a computer reboot the problem never appeared again. I haven't been able to reproduce it since then so it looks like it wasn't a coding problem or conventional configuration issue. The normal behaviour is as described in the marked answer to this question.
Eclipse will check every file in the project for main, but not your entire harddisk. Did you add the file with main to your project?

I tried to run this tet-cpp-client and in the output I am getting Gazeapilib.a file, and when I am trying to open it, it's giving me error that I can't open that file.
I want to know how to open this file, and what is the data of this file and how it can be used further in any program? I have not much knowledge about it so please help me to solve this error.
I am running this program in Ubuntu using cmake software.
The .a file is a library file which contains the definitions of the functions in the library that you compiled. It is not a standalone program and must be linked with other code to make a program. You must pass this library file to the linker after building your program.
