Newbie question..how to create container from a strictly local gcc executable?

[k9cfmark]

Very newbie question.
I can pull and execute the hello world example so the install on my PI is working.
How do I create a new locally written gcc program that doesn’t exist in a GitHub or docker repository?
Can someone point me to a dummies guide that gets me past THIS threshold?

The easiest is using a Makefile and a Containerfile, but if it is a single binary you can also just "import" it.

#include <stdio.h>
int main() { puts("Hello, World!"); }

$ gcc -o hello -static hello.c
$ tar cf hello.tar hello
$ podman import hello.tar hello
$ podman run --rm hello /hello
Hello, World!

Thank you!!
it seemed if you were already using repositories and had committed your base line, the instructions might make sense…..but I haven’t been, so it didn’t.
I’ll try the TAR and Import path.
thank so much!

The repository was supposed to have the "long" answer, including the Containerfile.

You can open new issues there ("PodmanHello"), if something is unclear about it?

You can also do a Containerfile with the following
from scratch
add hello /hello
podman build
podman run
