使用 CMake 和 MinGW 在 Windows 上使用 Boost 1.68.0 编译 C++ [英] Compiling C++ with Boost 1.68.0 on Windows using CMake and MinGW

问题描述

我想在 Windows 上使用 Boost 库，但这样做很麻烦.我从

我将以下内容添加到我的 CMake 文件中:

find_package(Boost 1.68 REQUIRED COMPONENTS 文件系统)# ...target_link_libraries(MyExecutable ${Boost_LIBRARIES})

我收到以下 CMake 错误:

它显然找不到 filesystem 但它在 C:\Boost\boost\filesystem (

如何设置我的 CMake 文件以正确使用 Boost?我也尝试设置 Boost 环境变量，但它仍然不起作用:

SET (BOOST_ROOT "c:/Boost")SET (BOOST_INCLUDEDIR "c:/Boost/boost")SET (BOOST_LIBRARYDIR "c:/Boost/libs")FIND_PACKAGE(Boost 1.68.0 REQUIRED COMPONENTS 文件系统)

解决方案

另外，Boost 说大多数东西都不需要编译，所以我没有这样做.

它找不到库 boost::filesystem.因为 boost::filesystem 是少数需要编译的库之一(所有你必须在 find package 命令中指定的必须编译).

您需要先构建提升:

./booststrap.sh

然后:

bjam

它会选择任何可用的编译器，因此您可能需要手动设置合适的工具集.

I want to use the Boost library on Windows but doing so has been troublesome. I downloaded the Windows package from here and extracted it to C:\Boost:

I added the following to my CMake file:

find_package(Boost 1.68 REQUIRED COMPONENTS filesystem)
# ...
target_link_libraries(MyExecutable ${Boost_LIBRARIES})

I'm getting the following CMake error:

  Some (but not all) of the required Boost libraries were found.  You may

  BOOST_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT

It apparently cannot find filesystem but it's there in C:\Boost\boost\filesystem (here is the documentation on FindBoost).

How do I setup my CMake file to use Boost properly? I tried setting the Boost environment variables as well but it still didn't work:

SET (BOOST_ROOT "c:/Boost")
SET (BOOST_INCLUDEDIR "c:/Boost/boost")
SET (BOOST_LIBRARYDIR "c:/Boost/libs")

FIND_PACKAGE(Boost 1.68.0 REQUIRED COMPONENTS filesystem)

解决方案

Also, Boost says that most things don't have to be compiled so I didn't do that.

It cannot find the library boost::filesystem. Because boost::filesystem is one of the few libraries that need to be compiled (all the ones that you have to specify in the find package command have to be compiled).

You need to build boost first:

./booststrap.sh

And then:

bjam

It picks up whatever compiler is available, so you may have to set the proper toolset manually.
