【中文标题】GitLab CI/CD 管道在构建 Debian 包时找不到 GCC

【英文标题】：GitLab CI/CD Pipeline can't find GCC when building Debian package

【问题描述】：

TL;DR - 为什么这条管道找不到 gcc？

在以下管道中，作业失败，因为它在 PATH 中找不到 gcc。 这是使用官方的 GCC docker 镜像。我也将此工作流程用于另一个项目。

image: gcc

  DEBVER: "1"

    - curl -O "$JSON_PARSER_MIRROR/libjsonparser-dev_1.1.0-1_amd64.deb"
    - dpkg -i libjsonparser1.1_1.1.0-1_amd64.deb
    - dpkg -i libjsonparser-dev_1.1.0-1_amd64.deb
    - mkdir -p build
  script:
    - which gcc
    - export PATH="$PATH:/usr/local/bin"
    - tar cvzf "../pam-oauth2_$VERSION.orig.tar.gz" --exclude='.git*' --exclude='*.deb' .
    - mv ../*.orig.tar.gz .
    - tar -xf *.orig.tar.gz -C build/
    - cd build
    - debuild -us -uc -d -i'(.*)'
  after_script:
    - rm -rf build
  artifacts:
    paths:
      - "*.deb"

【参考方案1】：

debuild 手册页说（在环境变量部分）：

由于环境变量会影响包的构建，因此通常 无意中，debuild 通过删除所有 除了 TERM、HOME、LOGNAME、GNUPGHOME 之外的环境变量， PGPPATH、GPG_AGENT_INFO、FAKEROOTKEY、DEB_*、（C、CPP、CXX、LD 和 F) FLAGS 变量及其 _APPEND 对应项和语言环境 变量 LANG 和 LC_*。如果未设置 TERM，则将其设置为“哑”，并且 PATH 设置为“/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11”。

参考： https://manpages.debian.org/jessie/devscripts/debuild.1.en.html

使用debuild --prepend-path=/usr/local/bin ...
