Building on RHEL 9.7

[tdiprima]

atch does not work on RHEL 9.7

Environment: RHEL 9.7, x86_64

Steps to reproduce:

git clone https://github.com/mobydeck/atch
cd atch
dnf install glibc-static  # required to build
make
./atch --help

Expected behavior: Help text is displayed.

Actual behavior: The process is immediately killed:

[1]  Killed  ./atch --help

Running under strace shows:

execve("./atch", ["./atch", "--help"], ...) = -1 EACCES (Permission denied)

SELinux is disabled on this system, so that is not the cause. No stale atch processes were running. The binary appears to compile successfully (with the expected getpwuid static linking warning), but cannot be executed.

Note: building also requires glibc-static, which is not mentioned in the README and needs the CodeReady Linux Builder repo enabled on RHEL 9.

Additional notes: The README mentions Alpine-based Docker builds — it may be that static builds against glibc are not well supported on RHEL/rpm-based distros. A note in the README about supported build platforms might be helpful.

Thank you.

@tdiprima thanks for opening this! 👍

my goal was to have a static binary built in Alpine using musl which makes it portable to run across all Linux distros.
my primary Linux is RHEL, then Amazon Linux and Ubuntu/Debian. single atch binary built statically with musl works across all of them. that's what many modern tools written in Rust usually do.

but I can add full support for building it on Linux using non-static glibc if that's what you need.
let me know please!

@arthurpro Thanks for the quick response! That makes total sense — I wasn't aware there was a pre-built static musl binary available. I just went straight to make from source.

Could you add a note to the README pointing to the pre-built binary as the recommended installation method? That would have saved me some trouble. Something like "download the release binary — it's a static musl build that works on any Linux distro".

No need to add glibc build support on my account — the pre-built binary approach is perfectly fine!

@tdiprima thank you for your input! I added installation section to the readme 👍
