Statically linking against libdbus-1

[schell]

I'm trying to cross compile from a number of host machines to the raspberry pi. I'm following the conversation in https://github.com/diwic/dbus-rs/blob/master/libdbus-sys/cross_compile.md. While looking for libdbus-1.so on my pi I saw that libdbus-1.a is right next to it (for me this is in /usr/lib/arm-linux-gnueabihf/libdbus-1.a). Are there any reasons we can't copy this static lib and then add a static-link feature to dbus-sys to link it statically?

Maybe my lack of knowledge about how static linking works is leading me to a false conclusion. Any help is much appreciated, and if it seems this is workable I'm willing to submit the patch.

Static linking is not my area of expertise either. I would argue though that if you find a way to link to libdbus-1.a where it resides (i e inside /usr/lib/arm-linux-gnueabihf/) rather than to copy the file around, it would be a better solution.

Feel free to experiment further and tell me the results!

It is definitely possible. I’m building statically linked binary with dbus-rs in connman-resolvconf – CI job for x86_64, job for aarch64.
