Gitlab CI/CD 的 C++17 问题

Question

I have been trying to set up CI/CD in the repo for a library I am working on. It requires C++17 and successfully compiles on my local machine. However, when the pipeline runs on Gitlab, when it compiles I get this error.

 $ make check

 all.cc.o

Here is my .gitlab-ci.yml file.

image: ubuntu:latest

stages:
    - build

before_script:
    - apt update -qq

Build:
    stage: build
    script:
        - apt install -y -qq cmake make git gcc g++
        - mkdir build
        - cd build
        - cmake ..
        - make check
    artifacts:
        paths:
            - public

I also have not changed any of the settings for CI/CD on Gitlab. I tried using debian:stable, but I just got a linker error to the functions I'm using from filesystem.

According to https://hub.docker.com/_/ubuntu/

The ubuntu:latest tag points to the "latest LTS", since that's the version recommended for general use. The ubuntu:rolling tag points to the latest release (regardless of LTS status).

At the time of writing, ubuntu:latest corresponds to Ubuntu 18.04 release, which might be too old.

Try ubuntu:rolling , which currently corresponds to Ubuntu 19.10.
