Multiplatform AMD64/ARM64 Support #290

Open ckirsch opened 3 years ago

ckirsch commented 3 years ago

Building a multiplatform docker image for linux/amd64 and linux/arm64 using:

docker build --platform linux/amd64,linux/arm64 .

currently fails in the linux/arm64 portion for at least two reasons:

  1. lib32gcc-9-dev seems to be unavailable
  2. openocd fails to recognize the system
  3. spike fails to build (which may be an issue we can't solve easily)

I am not sure how involved fixing all this is but I expect we need to support ARM64 sooner or later and therefore may not get around the issue.

I think for OpenOCD it's probably the best choice to kick it out of the docker image since the GDB+QEMU combo works really well and since OpenOCD is only needed when one wants to debug the bare-metal setup on actual hardware. Regarding Spike it would be interesting to see the reason why it fails to build. Could you paste the relevant output here?
