Enable builds for armv6 target #560

Open rahul-thakoor opened 7 months ago

rahul-thakoor commented 7 months ago

We currently build for

        aarch64-unknown-linux-gnu,
        armv7-unknown-linux-gnueabihf,
        x86_64-unknown-linux-gnu,
        i686-unknown-linux-gnu

I tried to enable armv6 builds, using target arm-unknown-linux-gnueabihf

Cross compiling libdbus fails. As per instructions here I added

[target.arm-unknown-linux-gnueabihf.env]
passthrough = ["RUSTFLAGS=-L /usr/arm-linux-gnueabihf/lib/ -L /usr/lib/arm-linux-gnueabihf/", "PKG_CONFIG_PATH=/usr/lib/arm-linux-gnueabihf/pkgconfig/","PKG_CONFIG_ALLOW_CROSS=true"]

but Flowzone build fails in the Publish step with :

I'm looking at this too, but unable to get Flowzone to run a build in my fork. I'm having to move away from it and rewrite the Dockerfile to actually do the build.
