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.

I have an old application, EagleCAD, from 2014, a 32bit app, I managed to install it on my linux (Debian based, 64bits) and it works fine, but I had to look for and install some lib manually.

How can I package all this, the bin and libs, into one that I could easily re-install on about any distro? AppImage? Flatpak? Snap?

Here's what I do in my docker images:

mkdir -p /lib-your-executable
ldd ./your-executable | tr -s '[:blank:]' '\n' | grep '^/' | xargs -I % cp % /lib-your-executable

Essentially, it's the same thing that you're doing, just automating getting the dependencies, and then copying everything in the lib-your-executable dir to your LD_LIBRARY_PATH. I don't know of a better way, other than statically-linking the binaries.

EDIT: fix typo in commands.
