Different Linux jobs mapping to Gcc versions

Hi,

I have noticed while using the Ubuntu1804 image that both Gcc 7 and Gcc 8 are installed. This is interesting for CI on my github repos, since I can use either of these. However, my test runs are long-running, so I'd split Gcc 7 and Gcc 8 into different jobs, rather than try to do it in a single Ubuntu1804 job.

After reading https://www.appveyor.com/docs/build-environment/#using-multiple-ima..., I thought I'd try this, although my .appveyor.yml does have Windows images too. This is what I tried, with the duplicate GCC_VERSION on the Ubuntu1804 image

image:
  - Ubuntu1804
  - Ubuntu
  - Visual Studio 2019 Preview
  - Visual Studio 2017
clone_depth: 10
configuration: Release
platform: AnyCPU
for:
  - matrix:
      only:
        - image: Ubuntu
    environment:
      GCC_VERSION: 5
  - matrix:
      only:
        - image: Ubuntu1804
    environment:
      GCC_VERSION: 7
      GCC_VERSION: 8
  - matrix:
      only:
        - image: Visual Studio 2017
    environment:
        VC_VERSION: 15.0
        VC_PRERELEASE_ARGS:
  - matrix:
      only:
        - image: Visual Studio 2019 Preview
    environment:
        VC_VERSION: 16
        VC_PRERELEASE_ARGS: "--VisualC.discoverprereleases"

Note that this is my normal structure, except for the duplicate GCC_VERSION environment variable under Ubuntu1804.

This fails, however, during parsing:

Error parsing appveyor.yml: (Line: 20, Col: 7, Idx: 330) - (Line: 20, Col: 18, Idx: 341): Duplicate key

Is there any way I can achieve this?
(I'm very comfortable setting up the update-alternatives scripts once I can configure the job structure of the project in AppVeyor.)

I'd really like to see a list of jobs such as

Ubuntu1804 (gcc 7)
Ubuntu1804 (gcc 8)
Ubuntu
Visual Studio 2019 Preview
Visual Studio 2017

appearing in my projects.

Many thanks,
Mark

   I would suggest you create a matrix this way:
   

   environment:
     matrix:
     - job_name: Ubuntu 16 and GCC 5
       APPVEYOR_BUILD_WORKER_IMAGE: Ubuntu1604
     - job_name: Ubuntu 18 and GCC 7
       APPVEYOR_BUILD_WORKER_IMAGE: Ubuntu1804
     - job_name: Ubuntu 18 and GCC 8
       APPVEYOR_BUILD_WORKER_IMAGE: Ubuntu1804
     - job_name: Visual Studio 2019 Preview
       APPVEYOR_BUILD_WORKER_IMAGE: Visual Studio 2019 Preview
     - job_name: Visual Studio 2017
       APPVEYOR_BUILD_WORKER_IMAGE: Visual Studio 2017
   

   Here are 2 jobs with the same Ubuntu1804 image.
   And then you can specify environment variables per each job:
   

   for:
     - matrix:
         only:
           - job_name: Ubuntu 16 and GCC 5
       environment:
         GCC_VERSION: 5
     - matrix:
         only:
           - job_name: Ubuntu 18 and GCC 7
       environment:
         GCC_VERSION: 7
     - matrix:
         only:
           - job_name: Ubuntu 18 and GCC 8
       environment:
         GCC_VERSION: 8
     - matrix:
         only:
           - job_name: Visual Studio 2017
       environment:
           VC_VERSION: 15.0
           VC_PRERELEASE_ARGS:
     - matrix:
         only:
           - job_name: Visual Studio 2019 Preview
       environment:
           VC_VERSION: 16
           VC_PRERELEASE_ARGS: "--VisualC.discoverprereleases"
   

   Also I would suggest you to use particular ubuntu images: ubuntu1804 and ubuntu1604. Since ubuntu image is just an alias for ubuntu1604 image as a default for those who dont care about OS version. We have a plan to switch this alias to point at ubuntu1804 image.

   Thanks! That worked, once I also removed the explicit image: node too, or I got a combinational explosion of jobs.

   And thanks for the tip for the planned switch of the Ubuntu alias.

   Mark.
