CMake的试图找到的刺激时，报告“Boost_DIR-NOT_FOUND” [英] CMake reports 'Boost_DIR-NOT_FOUND' when trying to find Boost

问题描述

我想建立一个我的机器上称为CSWNet库。 cmake的可以找到Boost_INCLUDE_DIR和Boost_LIB_DIR但它不能找到称为Boost_DIR一个选项，是包含用于升压一个CMake的配置文件的目录。它在哪里？请帮帮忙，谢谢提前。我得到的错误如下所示，我安装了从Ubuntu库升压和它安装在/ usr /本地。

 在/usr/local/share/cmake-2.8/Modules/FindBoost.cmake:429（消息）CMake的错误：
当请求升压的特定版本，则必须至少提供
主要和次要版本号，例如，1.34
（第一最近一次调用）调用堆栈：
演示/的CMakeLists.txt：149（find_package）
 

解决方案

看来你误会了意思 Boost_DIR 。

Boost_DIR 是用作提示通过CMake的寻找提升安装目录的环境变量。如果设置为 Boost_DIR-NOTFOUND ，做的不的意思是，它没有找到提振。 Boost_FOUND 用于指示搜索是否成功：

  find_package（升压REQUIRED螺纹）
如果（Boost_FOUND）
    消息（STATUS成功！）
万一（）
 

在一个成功的搜索的情况下，CMake的也将在配置阶段它看起来像

I want to build a library called CSWNet on my machine. Cmake can find Boost_INCLUDE_DIR and Boost_LIB_DIR but it cannot find an option called Boost_DIR which is a directory containing a CMake configuration file for Boost. Where is it? Please help, thanks ahead. The error I got is shown below and I installed boost from ubuntu repository and it's installed in /usr/local.

 CMake Error at /usr/local/share/cmake-2.8/Modules/FindBoost.cmake:429 (message):
When requesting a specific version of Boost, you must provide at least the
major and minor version numbers, e.g., 1.34
Call Stack (most recent call first):
demos/CMakeLists.txt:149 (find_package)

解决方案

It seems you misunderstood the meaning of Boost_DIR.

Boost_DIR is an environment variable used as a hint by CMake to find the boost installation directory. If this is set to Boost_DIR-NOTFOUND that does not mean that it did not find Boost. Boost_FOUND is used to indicate whether the search was successful:

find_package(Boost REQUIRED thread)
if(Boost_FOUND)
    message(STATUS "Success!")
endif()

In case of a successful search, CMake will also print a diagnostic message during the configure phase which looks something like

Boost version: 1.53.0
