[英]gitlab-ci.yml cpp coverage report
我正在嘗試使用Gitlab為c ++項目實現CI。 首先,我添加了一個簡單的c ++ hello world程序,它在我的PC和Gitlab CI中編譯和運行。
當我嘗試為相同的命令生成覆蓋率報告時,它適用於PC但不適用於Gitlab CI。
這是我的gitlab-ci.yml
# use the official gcc image, based on debian
# can use verions as well, like gcc:5.2
# see https://hub.docker.com/_/gcc/
image: gcc
build:
stage: build
# instead of calling g++ directly you can also use some build toolkit like make
# install the necessary build tools when needed
# before_script:
# - apt update && apt -y install make autoconf
script:
- g++ -Wall --coverage -fprofile-arcs -ftest-coverage helloworld.cpp -o mybinary
- ls
artifacts:
paths:
- mybinary
# depending on your build setup it's most likely a good idea to cache outputs to reduce the build time
# cache:
# paths:
# - "*.o"
# run tests using the binary built before
test:
stage: test
script:
- bash runmytests.sh
coverage:
stage: deploy
before_script:
- apt-get -qq update && apt-get -qq install -y gcovr ggcov lcov
script:
- ls
- g++ -Wall --coverage -fprofile-arcs -ftest-coverage helloworld.cpp -o mybinary
- ./mybinary
- ls
- gcov helloworld.cpp
- lcov --directory . --capture --output-file coverage.info
- lcov --remove coverage.info '/usr/*' --output-file coverage.info
- lcov --list coverage.info
- genhtml -o res coverage.info
這是生成的錯誤輸出
$ g++ -Wall --coverage -fprofile-arcs -ftest-coverage helloworld.cpp -o mybinary
$ ./mybinary

我怎樣才能解決這個問題?
通過將圖像名稱從gcc更改為ubuntu 16.04來解決問題,工作yml將如下所示
# use the official gcc image, based on debian
# can use verions as well, like gcc:5.2
# see https://hub.docker.com/_/gcc/
image: ubuntu:16.04
build:
stage: build
# instead of calling g++ directly you can also use some build toolkit like make
# install the necessary build tools when needed
before_script:
- apt update && apt -y install make autoconf gcc g++
script:
- g++ -Wall --coverage -fprofile-arcs -ftest-coverage helloworld.cpp -o mybinary
- ls

# depending on your build setup it's most likely a good idea to cache outputs to reduce the build time
