我下载了 xfstk 源代码并构建了它。我安装了依赖项boost，例如libusb-devel等...但尽管我安装了boost，但我收到错误消息，例如下面的消息，报告boost未安装。

答案1
当您尝试在 Linux 发行版上构建软件时，通常有两条路径可供选择。
选项
- 依靠 Linux 发行版的包管理器来为您完成繁重的工作
- 将您的自编译库合并到 LD 的路径中，以便构建/配置工具能够识别它。
对于第一点，您可以boost使用发行版包管理器进行安装。我更熟悉 Redhat 发行版，对于这些发行版，您可以这样做：
$ sudo yum search boost | grep ^boost | head
yum search boost | grep ^boost | head -10
boost-atomic.i686 : Run-Time component of boost atomic library
boost-atomic.x86_64 : Run-Time component of boost atomic library
boost-chrono.i686 : Run-Time component of boost chrono library
boost-chrono.x86_64 : Run-Time component of boost chrono library
boost-context.i686 : Run-Time component of boost context switching library
boost-context.x86_64 : Run-Time component of boost context switching library
boost-date-time.i686 : Run-Time component of boost date-time library
boost-date-time.x86_64 : Run-Time component of boost date-time library
boost-devel.i686 : The Boost C++ headers and shared development libraries
boost-devel.x86_64 : The Boost C++ headers and shared development libraries
然后从此输出中安装您需要的任何内容：
$ sudo yum install -y boost boost-devel ....
对于第二点，我已经在 U&L 问答中对此进行了介绍，标题为：编译时链接 boost 库的困惑。
