cmake在编译ur_rtde时could not find boost

img

boost包已经安装编译过了（我也很奇怪虽然只经过了几分钟），有stage里面的lib文件了，但是cmake编译的时候就显示couldnot find，用VS编译也总是在230行报错，怎么解决呢？

我看到了一篇博客，也是这个问题，特别好
https://blog.csdn.net/qq_26565435/article/details/129040032

系统变量加了吗

Boost库的安装路径未正确配置：将其添加到系统的环境变量中。
CMake缓存未正确更新： 删除CMake生成的缓存文件，然后重新运行CMake来重新生成缓存。
CMake版本不兼容？
缺少CMake依赖项？

boost与动态库之间的软链接问题:
具体可以参考一下下面这两篇文章，大佬写的很细
1、https://blog.csdn.net/alien_y/article/details/127670345
2、
https://blog.csdn.net/lc315yuhuofei/article/details/117999481

在cmake生成的工程里面手动添加lib依赖就可以。

BOOST_LIBRARYDIR环境变量没有设置，看下这篇文章修改一下：https://blog.csdn.net/lc315yuhuofei/article/details/117999481。

确保你的boost路径版本库文件都配置正确

cmake时提示错误Could NOT find Boost: missing: python-py27 ，boost依赖库报错原因以及解决方法
可以参考这个例子

（windows系统）

在CMakeLists.txt中添加：

（改成自己的路径）

set(BOOST_ROOT "D:/local/boost_1_79_0")

set(BOOST_INCLUDEDIR "D:/local/boost_1_79_0/boost")

set(BOOTS_LIBRARYDIR "D:/local/boost_1_79_0/stage/lib")

可能还是会报错


继续在CMakeLists.txt中添加：

set(Boost_LIB_PREFIX "lib")

set(Boost_ARCHITECTURE "-x64")

然后成功：
不知道你这个问题是否已经解决, 如果还没有解决的话:
  • 这篇博客: cmake-windows-boost中的 cmake中使用： 部分也许能够解决你的问题, 你可以仔细阅读以下内容或者直接跳转源博客中阅读:

    main.cpp

    //测试头文件库（ Header-Only Libraries）
#include <boost/lambda/lambda.hpp>  
#include <iostream>  
#include <iterator>  
#include <algorithm>

//测试库文件库（Boost Library Binary）
#include <boost/regex.hpp>
#include <string>
int main()  
{  
    using namespace boost::lambda;  
    typedef std::istream_iterator<int> in;  
    std::for_each(  
        in(std::cin), in(), std::cout << (_1 * 3) << " " ); 

    std::string line;
    boost::regex pat( "^Subject: (Re: |Aw: )*(.*)" );

    while (std::cin)
    {
        std::getline(std::cin, line);
        boost::smatch matches;
        if (boost::regex_match(line, matches, pat))
            std::cout << matches[2] << std::endl;
    }
}

    CMakeLists.txt

    cmake_minimum_required(VERSION 3.0)

set(PROJECT_NAME testboost)
project(${PROJECT_NAME})


set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(EXECUTABLE_OUTPUT_PATH ${CMAKE_SOURCE_DIR}/bin)

file(GLOB_RECURSE HEADERS *.h)
source_group("Header Files" FILES ${HEADERS})
aux_source_directory(. DIR_SRCS)



# 方法1： 显性设置boost的头文件与库文件目录， 发现此方法无效
#set(BOOST_INCLUDEDIR "H:\\cpp\\boost_1_61_0\\boost_1_61_0")
#set(BOOST_LIBRARYDIR "H:\\cpp\\boost_1_61_0\\boost_1_61_0\\stage\\lib")


#方法2：隐性设置 猜测通过设置BOOST_ROOT, 可以让cmake-3.10/Modules/FindBoost.cmake找到Boost相关的变量
#但是切记前提是 BOOST_ROOT符合目录结构规范
# 实验发现 当目录结构是 "BOOST_ROOT/include/boost-1_65_1/boost"和"BOOST_ROOT/lib"时可以找到${Boost_INCLUDE_DIRS}和${Boost_LIBRARIES}
# 如果目录结构是 "BOOST_ROOT/boost"和"BOOST_ROOT/stage/lib" 只能找到${Boost_INCLUDE_DIRS}
set(BOOST_ROOT "H:\\cpp\\build_boost_1_65_0\\")

SET(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)  
set(Boost_USE_STATIC_RUNTIME OFF)
#set(BOOST_NO_SYSTEM_PATHS TRUE)

#find_package(Boost 1.45.0 COMPONENTS *boost libraries here*)
#find_package(Boost REQUIRED) # wrong, ${Boost_LIBRARIES} will be empty
find_package(Boost REQUIRED COMPONENTS filesystem regex)
if(Boost_FOUND)
    MESSAGE(STATUS "Boost_INCLUDE_DIRS ${Boost_INCLUDE_DIRS}")
    MESSAGE(STATUS "Boost_LIBRARIES ${Boost_LIBRARIES}")
    include_directories(${Boost_INCLUDE_DIRS})
    add_executable(${PROJECT_NAME} ${DIR_SRCS} ${HEADERS})  
    target_link_libraries(${PROJECT_NAME} ${Boost_LIBRARIES})
endif()

    生成：

    cmake -G "Visual Studio 12 2013" ..

    打开*.sln,可以看到项目文件中已经配置好头文件与库文件


    vs编译

    cmake无法找到 boost

    情况1：

      Unable to find the Boost header files.  Please set BOOST_ROOT to the root
  directory containing Boost or BOOST_INCLUDEDIR to the directory containing
  Boost's headers.

    情况2：

      Could not find the following Boost libraries:

          boost_filesystem
          boost_regex

  Some (but not all) of the required Boost libraries were found.  You may
  need to install these additional Boost libraries.  Alternatively, set
  BOOST_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT
  to the location of Boost.

    参考：

    http://www.boost.org/doc/libs/1_65_1/more/getting_started/windows.html

    其它可以借鉴的方案：

    set( BOOST_COMPONENTS_NEEDED serialization )

    if(NOT BOOST_ROOT AND NOT $ENV{BOOST_ROOT} STREQUAL "")

            if( EXISTS ${BOOST_ROOT} ) 
                MESSAGE( STATUS "After removing the quotes " ${BOOST_ROOT} " was now found by CMake" )
            endif( EXISTS ${BOOST_ROOT})
        endif( NOT EXISTS ${BOOST_ROOT} )

如果你已经解决了该问题, 非常希望你能够分享一下解决方案, 写成博客, 将相关链接放在评论区, 以帮助更多的人 ^-^

这是cmake找不到boost库产生的错误，解决办法是手动安装这个库：

sudo apt-get install libboost-all-dev
再次执行安装。应该可以解决你的问题哦。

重新安装一下boost库

boost库的安装有问题，重新安装一下试试
