我已经安装了最新版本的Boost /usr/local(包含in /usr/local/include/boost和库/usr/local/lib/boost),我现在正尝试从源代码安装Wt,但CMake(版本2.6)似乎无法找到Boost安装.它尝试提供有关设置BOOST_DIR和Boost_LIBRARYDIR的有用建议,但我无法通过调整这些变量来使其工作.
我得到的最新错误消息是它找不到库,但它似乎表明它正在使用"/ usr/local/include"作为包含路径,这是不正确的(我可以'似乎解决了这个问题).是否有一个解决方案,他们的头顶,或者我需要在CMake内部捣乱才能弄明白？
我有以下C++开发设置:
OS X YosemiteCLion 140.2310.6(一个跨平台的C/C++ - 由JetBrains CMake用作构建系统的IDE )boost通过安装brew install boost到/usr/local/Cellar/boost/现在,我的目标是设置一个简单的项目并包含boost库.我只定义了一个看起来像这样的test.cpp文件:
#include <iostream>
#include <boost>
using namespace std;
int test() {
cout << "Hello, World!" << endl;
return 0;
}
我的CMakeLists.txt文件如下所示:
cmake_minimum_required(VERSION 2.8.4)
project(MyProject)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
include_directories("/usr/local/Cellar/boost/1.57.0/include/boost")
set(SOURCE_FILES main.cpp ./test.cpp)
add_executable(MyProject ${SOURCE_FILES})
当我构建项目时,我收到以下错误:
/Users/nburk/Documents/uni/master/master_thesis/MyProject/test.cpp:2:10:致命错误:找不到'boost'文件
make [3]:***[CMakeFiles/MyProject.dir/test.cpp.o]错误1 make [2]:***[CMakeFiles/MyProject.dir/all]错误2 make [1]:***[CMakeFiles/MyProject.dir/rule]错误2 make:***[MyProject]错误2
我在这里和那里调整路径,并使用add_library和target_link_libraries,没有一个使项目成功构建.
有人能指出正确的方向如何确保我可以boost在我的CLion C++项目中包含功能吗？
更新: 感谢@ Waxo的回答我在我的CMakeLists.txt …
我使用cmake生成的makefile来编译依赖于boost文件系统库的c ++文件.
在链接过程中,我收到以下错误:
Undefined symbols:

生成此错误的makefile中的操作是以下行:

一些谷歌搜索告诉我,这个错误似乎在使用boost文件系统库的mac上很常见,因为我必须链接到boost.system库或根据boost.system库创建我的项目.
如何在没有硬编码库路径的情况下强制cmake链接到库？
这是otool的结果:
otool -L /opt/local/lib/libboost_filesystem-mt.dylib
/opt/local/lib/libboost_filesystem-mt.dylib:
/opt/local/lib/libboost_filesystem-mt.dylib (compatibility version 0.0.0, …我正在尝试将 Boost 的线程库包含在我的 C++ 项目中。我的 CMake 文件是这样的：
cmake_minimum_required(VERSION 3.6)
project(LearningC)
find_package(Boost REQUIRED)
include_directories(${Boost_INCLUDE_DIR})
set(CMAKE_CXX_STANDARD 11)
set(SOURCE_FILES main.cpp Student.cpp Student.h)
add_executable(LearningC ${SOURCE_FILES})
target_link_libraries(LearningC ${Boost_LIBRARIES})
我收到错误：

我究竟做错了什么？
我有一个使用boost和zmq库的基于cmake的C ++项目。
我正在尝试使用Visual Studio Community 2017和vcpkg在Windows上构建它。
我按照项目页面上的说明安装了vcpkg。
现在，我可以看到已安装所需的软件包：
