如何将 openMP 安装到 Jenkins 镜像

Question

问题：

我已将 OpenMP 添加到 C++ 项目中，该项目是使用 cmake 构建的。我使用 ubuntu 18.04 在本地成功构建了它。 然后我尝试在 Jenkins 上构建它，其 ubuntu 版本也是 18.04 但是，当它构建时，它找不到 OpenMP 库。

那么如何配置 Jenkins 管道以使其包含 omp 库（抱歉我以前从未配置过 Jenkins）？ 我已经尝试过运行

sudo apt-get install libomp-dev

作为构建步骤 它失败了

17:56:57 E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied)
17:56:57 E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?

这是我执行 ld -lomp --verbose 时发生的情况

非常感谢任何帮助。预先感谢。

完成这两件事后，Jenkins 似乎能够使用 OpenMP 标志进行构建。

1. 在 Jenkins 中的实际构建注释之前添加

   sudo -s apt-get update

   作为构建步骤。
2. 在cmake文件中添加

   find_package(OpenMP)

   。
