boost_chrono_FOUND to FALSE所以包"boost_chrono“被认为找不到

Question

我试图通过遵循波纹来构建基于GitHub的构建指南，但是boost不断地抛出一些未知的错误。Boost已安装并正在运行。我按照构建指南的描述安装了boost_1_71_0。

有一个类似的问题这里，但您的问题似乎是相反的情况。

错误的重要部分在这里：

No suitable build variant has been found.

The following variants have been tried and rejected:

* libboost_chrono.so.1.71.0 (shared, Boost_USE_STATIC_LIBS=ON)

* libboost_chrono.a (shared runtime, Boost_USE_STATIC_RUNTIME=ON)

它显示了找到了哪些库，甚至给出了被拒绝的原因。在机器上找到的所有库都是共享库。但是，您的CMake配置表明您做了而不是，希望使用共享库(Boost_USE_STATIC_LIBS=ON和Boost_USE_STATIC_RUNTIME=ON)。要修复错误，您有两个选项：

1. 将Boost_USE_STATIC_LIBS设置为OFF，将Boost_USE_STATIC_RUNTIME设置为OFF： set(Boost_USE_STATIC_LIBS OFF) set(Boost_USE_STATIC_RUNTIME OFF) find_package(Boost .)
2. 还可以构建静态 Boost库，因此不仅可以在计算机上使用共享库。
