Dockerfile: xgo compile for darwin architecture fails about cgofuse HOT 7 CLOSED

Hey, Nick. Sorry for the delay in responding. I will have a look at this tomorrow.

from cgofuse.

I've decided to drop this build from rclone for the moment as it is only used for testing, so no urgency!

from cgofuse.

I believe the right thing here is to update the headers used in the Docker image.

I note that OSXFUSE 3.x series still uses the FUSE2 API, so it should be ok to update to latest OSXFUSE.

from cgofuse.

So the docker image has now been modified to include OSXFUSE 3.8.3 which includes the nonseekable symbol. (I chose OSXFUSE 3.8.3 and not the latest version because this is the last version that 7z can handle; newer versions of OSXFUSE use signed DMG's which 7z cannot handle.)

Unfortunately this is now failing during apt-get install because of missing files. The error message suggests that I should run apt-get update, which I already am except in an earlier Dockerfile step. I suspect that this is an effect of the Docker cache:

• This RUN step is pulled from cache:

  Step 3/7 : RUN dpkg --add-architecture i386 && dpkg --add-architecture amd64 && apt-get update && apt-get install -y --no-install-recommends p7zip-full
  ---> Using cache
  ---> c1143cf251eb
  

• This RUN step is being run because it came after the OSXFUSE RUN step which was just modified. Unfortunately it seems to fail because it needs a fresh apt-get update.

  Step 5/7 : RUN apt-get install -y --no-install-recommends libfuse-dev:i386 && apt-get install -y --no-install-recommends libfuse-dev:amd64 && apt-get download libfuse-dev:i386 && dpkg -x libfuse-dev*i386*.deb /

  ...
  Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
  

Is there a way to trigger DockerHub builds without the build cache? I no longer have easy access to Docker for Linux containers and I may not be able to fix this timely.

from cgofuse.

Ok, so I tried the kludge of adding a second apt-get update in the LIBFUSE installation RUN step and the build has now succeeded.

Can you please verify that the resulting xgo image works for you? Try pulling the latest tag for now.

from cgofuse.

I can confirm that that fixes the rclone builds - thanks Bill :-)

Sorry you had to debug on DockerHub - that is a miserable experience.

from cgofuse.

Excellent. I am closing this and will follow up on any additional work via rclone/rclone#4393.
