Ubuntu: Unable to locate libvips.42.so on application startup

[tylermmorton]

Hi! So far I've been using govips locally on my Intel Mac and it's been great. I started experiencing a lot of thorny issues when I went to package my application up for deployment, though. Perhaps this is due to my inexperience using C/C++ libraries within ubuntu images but this is the error I've been stuck on for a while:

error while loading shared libraries: libvips.so.42: cannot open shared object file: No such file or directory

I've done a lot of digging and I've attempted everything I can think of minus building from source.

• govips for ubuntu
• libvips installation guide
• libvips wiki - build for ubuntu
• ubuntu20: libvips-dev provided by ppa:tonimelisma/ppa is not available anymore #378

Any additional resources or things to try would be much appreciated. TYIA!

Turns out I missed something obvious. None of the shared libraries were being copied to the production image. Here's an updated docker container:

# The base image is a ubuntu image with Homebrew pre-installed.

RUN brew update-reset

ENV HOMEBREW_DIR=/home/linuxbrew/.linuxbrew

RUN go generate ./...

RUN ls -la ./.build

FROM ubuntu:latest as prod-base

I tried using base-workspace with all of the pre-installed homebrew dependencies as the starting point for the production image but the final product ended up being 5GB in size. Instead I added apt install libvips to a base ubuntu image. The application is able to start now, at least.
