Circleci and stm32 project

Hi community…

I am trying to use this project for trigger an automatic build with circleci for stm32 project…

Here you have a link to the repo

and this is the yaml file . …

version: 2
      - image: jumperio/vlab-gcc-arm:latest
      - checkout
      - run:
          name: build
          command: |
            sed -i -E 's/[A-Z]:\\.*\\workspace_[^\\]+\\[^\\]+\\/..\//' Debug/makefile
            make -C Debug all
      - store_artifacts:

every time i get failed and the error message it is the following …

makefile:61: *** multiple target patterns. Stop.

do you know the meaning ?

is it a problem the line 61 of the makefile ?

Thanks a lot
