【问题描述】：

我正在尝试在运行最新版本的 Fedora 32 的计算机上构建 BornAgain 软件。我之前设法做到了，但我什至不知道从哪里开始出现我遇到的错误。在我的终端中，我收到以下错误：

我一直在尝试按照他们网页上的说明进行操作： https://www.bornagainproject.org/documentation/getting-started/installation/linux-detailed/third-party/
https://www.bornagainproject.org/documentation/getting-started/installation/linux-detailed/build-and-install/

我最大的问题是他们有 Ubuntu、OpenSUSE 和 RedHat/CentOS 的说明。我认为罪魁祸首在于他们安装 devtoolset 的说明（试图遵循 RedHat 说明），这似乎不存在于 Fedora 存储库中。我基本上尝试安装任何相关的东西，并尝试了他们为每个发行版命名的所有包，但我无法超越上面输入的错误。

【问题讨论】：

再看一点 pthread_create 不是问题Looking for pthread_create in pthread - found 实际问题是它找不到Cerf 库。
仅供参考，真的不应该使用sudo 来运行cmake，如上所示。仅在需要时保存root 权限。
谢谢，我知道这一点，而且我通常不会将root 特权授予随机命令。但在这一点上，我变得绝望，正在尝试随机的东西，看看是否有效。显然它没有，但你是对的。随机授予root 特权是不好的做法，在这种情况下充其量是完全没有意义的。

谢谢艾尔克！鉴于Cerf_LIBRARIES 上 Ǵoogle 的点击量，我不敢相信我实际上花了一半的工作时间在这上面，我认为这是我尝试安装的软件中的特定内容。

鉴于您分别格式化了Cerf，我用谷歌搜索了一下，我很快发现我可以直接从 dnf 包管理器安装libcerf 和libcerf-devel。这立即解决了我的整个问题。谢谢你解决了这个头疼的问题，没早点发现我有点傻。
