[英]How do I compile C++ code with Boost on Msys2
I (think) that I have all the libraries installed that I need, eg,我(认为)我已经安装了我需要的所有库,例如,
pacman -S mingw-w64-x86_64-boost
Also the common development libraries that the msys2 install documentation recommends.还有 msys2 安装文档推荐的通用开发库。 I am testing it out with these includes:
我正在用这些来测试它,包括:
#include <iostream>
#include <vector>
#include <string>
#include <boost/program_options.hpp>
I've tried various permutations such as below with the same error:我已经尝试了各种排列,例如下面的相同错误:
$ g++ -std=c++11 main.cpp -lboost_programoptions -I /mingw64/include/boost/ -o main
main.cpp:10:10: fatal error: boost/program_options: No such file or directory
10 | #include <boost/program_options>
| ^~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
How do I get boost with msys2 working?我如何通过 msys2 工作获得提升?
Update:更新:
Because of the question of @HolyBlackCat I discovered that there are two different versions of gcc installed, gcc 10.2 and mingw-w64-x86_64-gcc 10.3.由于@HolyBlackCat的问题,我发现安装了两个不同版本的gcc,gcc 10.2和mingw-w64-x86_64-gcc 10.3。 I'm not sure which one I should get rid of.
我不确定我应该摆脱哪一个。 See below,
pacman -Rcns
is intended to mean, "remove this package and all of its dependencies" as per here .见下文,
pacman -Rcns
的意思是,按照此处“删除此 package 及其所有依赖项”。
$ pacman -Rcns gcc

Update #2更新 #2
I uninstalled gcc 10.2 and started mingw64 vs. msys and now I get this:我卸载了 gcc 10.2 并启动了 mingw64 vs. msys,现在我明白了:
user@host MINGW64 /c/Users/user/boostexample
$ g++ main.cpp -o main -lboost_program_options
C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lboost_program_options
collect2.exe: error: ld returned 1 exit status
Update #3更新 #3
I needed to invoke the compiler with:我需要调用编译器:
g++ main.cpp -o main -lboost_program_options-mt
and it compiled fine.它编译得很好。 I suppose I should find where in the documentation these norms are specified.
我想我应该在文档中找到指定这些规范的位置。
Curating HolyBlackCat's comments into an answer that worked for me:将 HolyBlackCat 的评论整理成对我有用的答案:
mingw64
shell, not msys*
.mingw64
shell,而不是msys*
。 (Not sure what purpose the division into multiple binaries serves. Perhaps it matters for other windows versions.) /mingw64/lib
that matches what you wanted to compile against./mingw64/lib
下搜索与您要编译的内容相匹配的存档文件。 So if foobar
is name of the functionality you wanted look for libfoobar.a
there.foobar
是您想要的功能名称,请在那里查找libfoobar.a
。g++ main.cpp -o main -lfoobar
g++ main.cpp -o main -lfoobar
编译Install them using pacman
.使用
pacman
安装它们。
$ pacman -S mingw-w64-x86_64-boost mingw-w64-x86_64-cmake mingw-w64-x86_64-toolchain
Create a CMakeList.txt with boost , using OLen's answer.使用 OLen 的回答,使用boost 创建一个 CMakeList.txt 。

In the above, I have used only 'mingw-64', this will allow the binary to run on regular windows if you have DLLs in '/mingw64/bin' on your path.在上面,我只使用了“mingw-64”,如果你的路径上的“/mingw64/bin”中有 DLL,这将允许二进制文件在常规 windows 上运行。
The other toolchain (un-prefixed g++) requires an msys2 shell to run the program from (at least that is the easiest way).另一个工具链(无前缀的 g++)需要一个 msys2 shell 来运行程序(至少这是最简单的方法)。
