From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Checking dependencies for manual build and install of software (self.linux)

I am pretty new to linux so please excuse any foolish mistakes.

I am trying to manually install gpu-screen-recorder(GSR) to get rid of an annoying password prompt that I can't seem to disable in the flatpak version. I know there must be some way to do it because this prompt didn't show up on Pop!_OS, but maybe it's just not possible on Nobara KDE/Fedora. I noticed in the install.sh of GSR, that setcap cap_sys_admin+ep is called on the executable. So if you know any way of replicating something like that for flatpaks that is simpler than installing GSR manually, feel free to let me know.

I tried checking the dependencies listed, but was unable to figure out how to really make sure they are installed and accessible for GSR.

For example: I tried checking for libglvnd by running dnf list libglvnd. Sure enough, it returns

Installed Packages
libglvnd.i686                                         1:1.6.0-2.fc38                                       @anaconda
libglvnd.x86_64                                       1:1.6.0-2.fc38                                       @anaconda

But then I tried checking for mesa, so I ran dnf list mesa. But it returned

Available Packages
mesa.src                                    23.2.1-1.fc38                                     nobara-baseos         
mesa.src                                    23.2.1-1.fc38                                     nobara-baseos-multilib

It says 'available packages', so not installed, right?

Well, glxinfo -B says I am using mesa 23.2.1, so it seems to be installed, I guess?

So, just assuming I had everything necessary, I cloned the repo and tried to just run install.sh. However, of course I get an error message: wayland-scanner: command not found.

I am a bit confused because I am running on wayland, and checked using loginctl show-session 1 -p Type.

How do I properly make sure the dependencies are available?

If you're going to install from source at least change the compile config options so the prefix defaults to /opt/program-name.

You can further integrate with the system by adding the /opt/program/bin/ and sbin/ dirs to the PATH variable, and add lib/ to /etc/ld.so.conf but it should not be needed normally — only if other programs need to compile against this one.

You can also simplify integration by making common dirs for example /opt/.bin and /opt/.lib, adding only those to PATH and ld, and symlinking binaries and libraries from all /opt programs to them.

those are nice tips, thank you!
