Docker-based cross-compile setup for netopeer2 + full dependency stack (x86_64 / ARM32 / ARM64)

[sairohan0]

Hi all,

I put together a small build system for cross-compiling netopeer2 and its entire dependency chain (zlib, openssl, libssh, libpsl, libxcrypt, pcre, curl, libyang, sysrepo, libnetconf2, netopeer2, cJSON*, rabbitmq-c*) for x86_64, ARM32 (armhf), and ARM64 (aarch64) — all inside a single Docker Compose run, producing a ready-to-use sysroot per architecture.

It was born out of needing repeatable netopeer2 builds for embedded/ARM targets without hand-rolling the whole dependency chain and cross-toolchain setup each time.

What it does:

• One ./build.sh builds all three architectures back to back
• CMake toolchain files handle the ARM cross-compilation (arm-linux-gnueabihf-* / aarch64-linux-gnu-*)
• Output lands in per-arch sysroots (/opt/sysroots/x86_64, /arm32, /arm64) with flattened lib/, include/, pkgconfig/ dirs ready for downstream builds

Note: dependency source trees aren't vendored in the repo — you bring your own versions of each library into the repo root before building (the README lists the exact folder names expected).

Happy to hear feedback, or if this overlaps with something that already exists in the ecosystem, would love pointers to that too.

*rabbitmq-c and cJSON are optional
