It’s been a long day and I’m probably not in the best state of mind to be asking this question, but have you guys solved packaging yet?
I want to ship an executable with supporting files in a compressed archive, much like the Windows exe-in-a-zip pattern. I can cross-compile a Win32 C program using MinGW that will always use baseline Win32 functionality, but if I try to build for Linux I run into the whole dependency versioning situation, specifically glibc fixing its symbol version to whichever Linux I happen to be building from at the time. But if I try to static link with musl, the expectation is that everything is static linked, including system libraries that really shouldn’t be.
AppImage is in the ballpark of what I’m looking for, and I’ve heard that Zig works as a compatibility-enhancing frontend if you’re compiling C. I’d just like something simple that runs 99% of the time for non-technical end users and isn’t bloated with dependencies I can’t keep track of. (No containers.) Is this easily achievable?
Glibc preserves backward compatibility, so if you build against the oldest version you want to support, the resulting binary will work with newer ones.
However that’s definitely not what I recommend to do. Better learn packaging and build native packages for distros you are going to support. OBS can make this a bit easier (if your software is FOSS), but any modern CI will also do the job.
