青旅半醒 2022-07-17 02:41 498阅读 0赞

最近在ubantu上使用Qt开发进行开发,遇到不能使用输入法输入中文的问题,有点头疼,于是百度谷歌双管齐下,查阅各方资料,综合各种解决方案,kill 了这个问题,在此做下笔记,也希望能够帮助到同样遇到此问题的人。

系统版本: ubantu 16.04 LTS

输入法: 搜狗输入法

本人Qt版本: Qt5.6

解决方法,编译 fcitx-qt5 源码

# 一、解决步骤 #

1.1 前期准备工作

### (1).安装cmake ###

sudo apt-get install cmake

(2) 安装 fcitx-libs-dev

sudo apt-get install fcitx-libs-dev

(3) 设置环境变量

export PATH="/home/ProgramFiles/Qt5.6.1/5.6/gcc_64/bin":$PATH

其中蓝色部分为安装Qt的位置,,这个根据个人的安装位置情况而定.

### (4) 下载 fcitx-qt5 源码 ###

git clone https://github.com/fcitx/fcitx-qt5

如果显示没有权限获取,及表明没有秘钥,则可以打开这个网址直接到github上去下载压缩包,再解压即可.

## 1.2 执行编译操作 ##

编译 fcitx-qt5

cd fcitx-qt5
    
     cmake .
    
     make
    
     sudo make install

## 1.3 拷贝编译得到的 so 文件 ##

编译成功之后,将编译得到的libfcitxplatforminputcontextplugin.so 文件拷贝到Qt的按装目录下

`Tools/QtCreator/bin/plugins/platforminputcontexts` 或`Tools/QtCreator/lib/Qt/plugins/platforminputcontext`

`之中,两个目录由安装情况而定,有的会是`第一个路径,有的则是第二个路径,然后再继续将这个文

件放在Qt5.6.1/5.6/gcc\_64/plugins/platforminputcontexts之下 最后重启Qt或则重启电脑则可以了.

# 二、在此过程中可能遇到的问题 #

## 2.1 缺少 ECMConfig.cmake 和ecm-config.cmake ##

CMake Error at CMakeLists.txt:8 (find_package):
    
    Could not find a package configuration file provided by "ECM" (requested
    
    version 1.4.0) with any of the following names:
    
    ECMConfig.cmake
    
    ecm-config.cmake
    
    Add the installation prefix of "ECM" to CMAKE_PREFIX_PATH or set "ECM_DIR"
    
    to a directory containing one of the above files. If "ECM" provides a
    
    separate development package or SDK, be sure it has been installed.
    
    -- Configuring incomplete, errors occurred!

下载 extra-cmake-modules\_1.4.0.orig.tar.xz

链接: [https://launchpad.net/ubuntu/+source/extra-cmake-modules/1.4.0-0ubuntu1][https_launchpad.net_ubuntu_source_extra-cmake-modules_1.4.0-0ubuntu1]

解压后进行如下操作:

cd  extra-cmake-modules-1.4.0
    
    cmake .
    
    sudo make install

## 2.2 缺少Qt5Config.cmake 和qt5-config.cmake ##

CMake Error at CMakeLists.txt:29 (find_package):
    
    Could not find a package configuration file provided by "Qt5" (requested
    
    version 5.1.0) with any of the following names:
    
    Qt5Config.cmake
    
    qt5-config.cmake
    
    Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH or set "Qt5_DIR"
    
    to a directory containing one of the above files. If "Qt5" provides a
    
    separate development package or SDK, be sure it has been installed.

设置 CMAKE\_PREFIX\_PATH 环境变量

export CMAKE_PREFIX_PATH="/home/cc/ProgramFiles/Qt5.6.1/5.6/gcc_64/lib/cmake/"

## 2.3 缺少 xkbcommon ##

- Found PkgConfig: /usr/bin/pkg-config (found version "0.26")
    
    -- Could NOT find XKBCommon_XKBCommon (missing: XKBCommon_XKBCommon_LIBRARY XKBCommon_XKBCommon_INCLUDE_DIR)
    
    CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:108 (message):
    
    Could NOT find XKBCommon (missing: XKBCommon_LIBRARIES XKBCommon) (Required is at least version "0.5.0")

进行安装即可.

sudo apt-get install libxkcommon-dev

编译:

sudo apt-get install bison
    
    ./configure --prefix=/usr --libdir=/usr/lib/x86_64-linux-gnu --disable-x11
    
    make
    
    sudo make install
