1. 软件安装
- Jetbrains CLion
- CLion: A Cross-Platform IDE for C and C++ by JetBrains
- https://www.jetbrains.com/clion/
- jetbrains-agent: Jetbrains 全家桶项目。
- https://gitee.com/pengzhile/jetbrains-agent
- Cmake(可选)
- 除非必要,一般不必另安装,可以使用Clion中自带的Cmake。如一定要选用个人安装的,请注意在工具链中的Cmake路径设置,否则可以直接选bundled即可。
- Qt5 for MinGW64 use msys2
- msys2:下载安装msys2,在MinGW-64下载页面(url: http://mingw-w64.org/doku.php/download ),进入msys2页面进行下载,也可直接从http://www.msys2.org进入下载( 32位:msys2-i686-20180531.exe;64位:msys2-x86_64-20180531.exe),建议安装在磁盘空间大的磁盘目录下,因为安装Qt及依赖软件需要占用很多存储空间,本例中安装在C:\msys64目录下,并将此目录和bin目录加入系统路径中。
- Pacman:msys2 移植了Arch Linux 上的软件包管理系统 Pacman,有了包管理系统,升级、安装新的软件就很简单了(pacman常用命令参数见文末说明)。在此管理系统中,软件包的命名中前缀为“mingw-w64-”,然后是针对命名32位或64位系统使用, "-x86_64-" for 64-bit, "-i686-" for 32-bit。下载的软件包也会据此安装部署到不同的目录中,如32位的软件会部署到C:\msys64\mingw32中,64位的会部署到C:\msys64\mingw64中。软件下载包是放在C:\msys64\var\cache\pacman\pkg中。
- Qt5:msys2提供编译好的MinGW-w64套件,一般提供了32位和64位两个版本。Qt也分别有编译好的32位和64位版本,以及静态链接和动态链接共4个版本,以及QtCreator。(mingw-w64-i686-qt5,mingw-w64-i686-qt5-static,mingw-w64-i686-qt-creator;mingw-w64-x86_64-qt5,mingw-w64-x86_64-qt5-stati, mingw-w64-x86_64-qt-creator)。
- 启动msys2的命令行窗口,通过pacman下载安装MinGW版本的Qt5。在此已32位的为例。
- pacman -S mingw-w64-i686-qt5 mingw-w64-i686-qt5-static
- 下载安装make和gdb工具;
- pacman -S mingw-w64-i686-make mingw-w64-i686-gdb
- 安装完成后,在系统路径中添加bin路径;
- C:\msys64;C:\msys64\mingw32\bin
- 至此,即可正常使用Qt5了。可以用Qt5自带的示例测试是否安装正常,用CLion编译过程附后。
- 第三方库安装(以QWT为例)
- QWT:全称是Qt Widgets for Technical Applications,是一个基于LGPL版权协议的开源项目, 可生成各种统计图。它为具有技术专业背景的程序提供GUI组件和一组实用类,其目标是以基于2D方式的窗体部件来显示数据, 数据源以数值,数组或一组浮点数等方式提供, 输出方式可以是Curves(曲线),Slider(滚动条),Dials(圆盘),Compasses(仪表盘)等等。该工具库基于Qt开发,所以也继承了Qt的跨平台特性。在msys2中针对MinGW-w64提供了两个版本(mingw-w64-i686-qwt-qt5 mingw-w64-x86_64-qwt-qt5)。本文以32位为例,进行下载安装。因为第三方库的路径都是基于msys2的,所以无需后续系统路径的配置。
- pacman -S mingw-w64-i686-qwt-qt5
- 至此,如果需要用Clion作为IDE,用MinGW作为编译器,用CMake作为项目构建工具,开发基于Qt5、qwt的C++图形GUI项目,就已经基本具备条件了。
- 其他可选的编译器或Qt版本
- 基于MinGW的Qt5官方安装包模式:此模式下,需用其自带的MinGW,如使用qwt,需对qwt源码进行此版本下的编译生成,方可使用。
- 下载地址: http://download.qt.io/archive/qt/5.7/5.7.1/qt-opensource-windows-x86-mingw530-5.7.1.exe
- 安装需要注意,选择Tools里面的MinGW5.3.0,安装的Qt for MinGW的Tools中含有gcc/g++,是用来编译此版本Qt项目的。在CLion中,如图设置Toolchains:
- 基于MinGW的Qt5官方安装包模式:此模式下,需用其自带的MinGW,如使用qwt,需对qwt源码进行此版本下的编译生成,方可使用。
-
- LLVM Clang for MinGW64 (可选)
- Step 1: Install the msys2.
- Step 2: Launch the msys terminal and install llvm/clang.
- pacman -S mingw-w64-i686-llvm mingw-w64-i686-clang mingw-w64-i686-make mingw-w64-i686-gdb
- Step 3: Let CMake detect clang from the environment variables.
- CLion Setting Toolchains
- LLVM Clang for MinGW64 (可选)

然而,这种方法编译Qt项目,生成的项目执行文件比用QtTool的MinGW编译的大!
2. CLion开发Qt5环境配置
- CLion Setting Toolchains
- CLion Setting CMake(除选择Build Type和Toolchain外,其他都是默认项)
- 一般在做了工具链修改或项目CMakeLists.txt文件的修改,需要重新构建项目,再进行项目编译调试。通过在CLion中,选择Tools -> CMake -> Reset Cache and Reload Project
3. 开发示例
- Qt5 for msys2 MinGW32
- CMakeLists.txt for qt5 project,在CLion中,可用MinGW32、MinGW for Qt Tool、Clang编译工具链均可。

- 示例用QWT自带的示例Radio(可从https://sourceforge.net/projects/qwt/files/qwt/下载的压缩包中获得),在项目中去掉.pro文件,然后添加相应针对qwt的CMakeLists.txt文件,在CLion中,用基于msys2的工具链进行编译调试,顺利成功!
注意事项
- 在测试过程中发现,一定要注意非自编译的库,如Qt、Qwt等,都是从官方或msys中获得,必须要保证其已编译的库所使用的工具环境一致性,不同工具环境编译的库是不能互相调用的。如需要使用msys中的qwt库,就一定要用其对应的Qt库(同样从msys中获得的),因为都是用msys中的MinGW生成的,所以在使用时不会有问题;如果用Qt官方的MinGW版本的Qt进行使用,则不能成功,即使编译通过,会输出:Process finished with exit code -1073741511 (0xC0000139),打开执行文件会提示无法定位程序入口的弹窗,如必须使用此版本Qt,那需要通过qwt源码,用此Qt版本工具中的MinGW重新编译生成qwt库,再行使用方可。同时,这也体现在CLion的Toolchains设置中,各项也都应保持一致。
附:pacman基本命令参数
更新本地软件包: pacman -S --refresh 可以缩写为:pacman -Sy 升级软件包: pacman -S --refresh --sysupgrade 可以缩写为:pacman -Syu 列出所有已安装软件包: pacman -Q --explicit 或者 pacman -Q -e 可以列出所有的软件组: pacman -Q --groups 安装新的软件包: pacman -S比如安装 Qt5: pacman -S mingw-w64-i686-qt5 注:可以不用明确软件包版本,系统会根据依赖项进行自动匹配下载相应版本。 搜索软件包: 如果不清楚软件的准确名称,可以通过核心软件名查询软件包的名称。 pacman -Ss 比如搜索gcc相关的软件 pacman -Ss gcc 删除软件包: pacman -R

开发环境安装配置示例:
https://www.devdungeon.com/content/install-gcc-compiler-windows-msys2-cc
- Install gcc compiler on Windows with MSYS2 for C/C++
- Installing and running MSYS2
Download MSYS2 from http://www.msys2.org/. Download the .exe file and follow the installation instructions on the site. After installing, navigate to the directory where it was installed, and run msys2.exe. For this tutorial, we will assume the default location of C:\msys64. After opening it you should find yourself in a bash shell.
- Updating MSYS2
MSYS2 uses the pacman package manager that the Arch Linux distribution uses. After your initial install it is a good idea to update all the packages. Update everything using:
pacman –Syu pacman –Su
- Installing gcc using MSYS2
In the MSYS2 bash shell, use pacman again to install the build toolchain and compilers. Run the command below to install the mingw-w64-x86_64-toolchain package group.
# Install make, autoconf, etc to C:\msys64\usr\bin pacman -S base-devel
# pacman -S base-devel 1) asciidoc 2) autoconf 3) autoconf2.13 4) autogen 5) automake-wrapper 6) automake1.10 7) automake1.11 8) automake1.12 9) automake1.13 10) automake1.14 11) automake1.15 12) automake1.16 13) automake1.6 14) automake1.7 15) automake1.8 16) automake1.9 17) bison 18) diffstat 19) diffutils 20) dos2unix 21) file 22) flex 23) gawk 24) gdb 25) gettext 26) gettext-devel 27) gperf 28) grep 29) groff 30) help2man 31) intltool 32) lemon 33) libtool 34) libunrar 35) libunrar-devel 36) m4 37) make 38) man-db 39) pacman 40) pactoys-git 41) patch 42) patchutils 43) perl 44) pkg-config 45) pkgfile 46) quilt 47) rcs 48) scons 49) sed 50) swig 51) texinfo 52) texinfo-tex 53) ttyrec
- Installing other packages with pacman
If you want to compile an SSL program that links to libssl and libcrypto with -lssl -lcrypto you will need to install openssl-devel as shown below. There are many other devel packages. For example, libbz2-devel, libelf-devel, libunrar-devel, and libyaml-devel. The environment is rather limited, but it can be useful for learning.
# Install all *-devel packages pacman -S development
Packages included in "development" group:
:: There are 78 members in group development: :: Repository msys 1) apr-devel 2) apr-util-devel 3) aspell-devel 4) bash-devel 5) cloog-devel 6) gamin-devel 7) gettext-devel 8) glib2-devel 9) gmp-devel 10) heimdal-devel 11) icu-devel 12) isl-devel 13) jansson-devel 14) jsoncpp-devel 15) libarchive-devel 16) libargp-devel 17) libassuan-devel 18) libatomic_ops-devel 19) libbobcat-devel 20) libbz2-devel 21) libcares-devel 22) libcrypt-devel 23) libcurl-devel 24) libdb-devel 25) libedit-devel 26) libelf-devel 27) libevent-devel 28) libexpat-devel 29) libffi-devel 30) libgc-devel 31) libgcrypt-devel 32) libgdbm-devel 33) libgnutls-devel 34) libgpg-error-devel 35) libgpgme-devel 36) libgpgme-python2 37) libgpgme-python3 38) libguile-devel 39) libiconv-devel 40) libidn-devel 41) libidn2-devel 42) libksba-devel 43) liblz4-devel 44) liblzma-devel 45) liblzo2-devel 46) libmetalink-devel 47) libneon-devel 48) libnettle-devel 49) libnghttp2-devel 50) libnpth-devel 51) libp11-kit-devel 52) libpipeline-devel 53) libpsl-devel 54) libreadline-devel 55) librhash-devel 56) libsasl-devel 57) libserf-devel 58) libsqlite-devel 59) libssh2-devel 60) libtasn1-devel 61) libtirpc-devel 62) libtre-devel-git 63) libunistring-devel 64) libuv-devel 65) libxml2-devel 66) libxslt-devel 67) libyaml-devel 68) mpc-devel 69) mpfr-devel 70) ncurses-devel 71) openssl-devel 72) pcre-devel 73) pcre2-devel 74) protobuf-devel 75) ucl-devel 76) util-macros 77) xproto 78) zlib-devel
- Optional: Add executables to your Windows PATH
If you want to access everything from your Windows Command Prompt, then add the bin directory to your Windows PATH environment variable. Keep in mind this adds a lot of executables to your path which might conflict with other applications. The usr\bin\ directory contains the whole slew of executables listed above. There is a lot of unnecessary stuff in that directory. mingw64\bin\ directory :
;C:\msys64;C:\msys64\mingw64\bin;C:\msys64\usr\bin
- Header files and libraries
Libraries and include files can be found in two places.
# The dynamic lib runtime .dll files will be in bin dirs # Add the bin directory to PATH environment variable so it can find the .dll files C:\msys64\mingw64\bin C:\msys64\usr\bin # Static libraries C:\msys64\usr\lib C:\msys64\mingw64\lib # Header files C:\msys64\usr\include C:\msys64\mingw64\include
- A note about msys vs mingw64 repos
Some things are only available in the msys/ repo like vim and git, and will only be available in \usr\bin\. Some things like gcc are available in msys\, mingw32\, and mingw64\ repos and can potentially end up being installed in both \usr\bin\ and \mingw64\bin\. This is where you have to be careful about how you set up your PATH environment variable. If you add \usr\bin\ in order to make vim or git available, you will also add everything in that directory, which may conflict with something if you also add the \mingw64\bin\ directory to your path. If you only want the toolchain without as much extra stuff, use the mingw64 packages. Then you can add only the \mingw64\bin directory to your PATH if desired. The mingw64 repository generally has more libraries available for install that are unavailable in the general msys repo (e.g. SDL, exif, freeglut). The msys packages are intended to be used inside the msys shell, and the mingw packages are intended to be used outside of msys2.
