前言：参考了网上一堆的文章，还是出现了一堆的问题，一句话能用apt-get install安装的千万别自己下源码编译，没有新版本就GOOGLE 关键字+PPA找到新版本源，用add-apt-repository命令添加,然后update下，再apt-get install试试有没有，如果要学习另当别论。

一原因分析：

根据网上和自己的编译经验分析觉得QT5.6之所以无法切换fcitx的输入法是因为qt5的库文件和插件都没有加入fcitx输入法管理工具的相关支持，可能能用ibus，因为我在platforminputcontexts目录中看到有，如此的话，那么要想使之支持fcitx就要自己添加这些库文件和插件了。这里是我编译好的文件，你可以直接下载用。我的云盘访问密码 72f4

方法吗？如下两步

1.先进入QT5.6的目录，寻找“platforminputcontexts”这个输入法插件目录，你可以看到两个目录里面现有的插件是不是都有IBUS呢，把我压缩包里的libFcitx…so那个文件拷到这两个目录下就行。

插件目录：

anzyelay@ubuntu:Qt5.6.0$ find . -name platforminputcontexts
./Tools/QtCreator/lib/Qt/plugins/platforminputcontexts
./5.6/gcc_64/plugins/platforminputcontexts
anzyelay@ubuntu:Qt5.6.0$ ls ./Tools/QtCreator/lib/Qt/plugins/platforminputcontexts
libcomposeplatforminputcontextplugin.so  libibusplatforminputcontextplugin.so

2.再把压缩包中剩下的那6个库文件都放到“Qt5.6.0/Tools/QtCreator/lib/qtcreator”目录下或“Qt5.6.0/5.6/gcc_64/lib”目录下，我试过放一个就行，最好两个都放吧，可能有别的用处呢。。这两个目录都是库文件目录，其它版本的可参考找寻。
3.重启qtcreator程序，切换下输入法试试，不行就重启下机子，可能输入法的快捷切换键跟QT有冲突，可以试着改下看看。

二获得插件的方法

1. 使用apt-get安装

首先寻找了下自己电脑,一般在/usr/lib/x86_64-linux-gnu/目录下,看看有没有qt5,可能只有qt4,于是只能安装fcitx-frontend-qt5,如果安装成功会在其下有个plugin目录，我们要的libfcitxplatforminputcontextplugin.so就有这里，你可以搜索下。

一般安装会出如下问题，没有可用包，这时就要自己去找源更新后在安装了。反正我是找到了也一堆的依赖包缺失，没办法版本是12.04的。怎么弄都不行，用方法二了。

[email protected]:build$ sudo apt-get install fcitx-frontend-qt5
[sudo] password for anzyelay:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package fcitx-frontend-qt5 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package ‘fcitx-frontend-qt5‘ has no installation candidate

2.自己编译fcitx-qt5安装

编译的前提条件：

首先说明，编译fcitx-qt5要用cmake来生成Makefile编译文件，所以要先安装cmake程序。

再来直接看cmake成功后的提示如下：

[email protected]:build$ cmake ..
-- checking for module ‘fcitx-utils‘
--   found fcitx-utils, version 4.2.0
-- checking for module ‘fcitx-config‘
--   found fcitx-config, version 4.2.0
--
-- The following OPTIONAL packages have been found:

 * PkgConfig

-- The following REQUIRED packages have been found:

 * ECM (required version >= 1.4.0)
 * Qt5DBus
 * Qt5Widgets
 * Qt5 (required version >= 5.1.0)
 * Qt5Gui (required version >= 5.1.0)
 * XKBCommon (required version >= 0.5.0) , Keyboard handling library using XKB data , <http://xkbcommon.org>
 * Qt5Core

-- Configuring done
-- Generating done
-- Build files have been written to: /home/anzyelay/Downloads/fcitx-qt5/build
[email protected]:build$

上面说明了要编译fcitx-qt5需要的依赖包有：ECM，XKBCommon，Qt5DBus，Qt5Widgets，Qt5，Qt5Gui，Qt5Core以及fcitx-utils 模块，Qt5这几个应该安装Qt5后就会有不用担心，fcitx-utils ，ECM，XKBCommon可能要自己安装。

还有一点要说明，这个插件的编译要用到C++11的支持。如果你的GCC/G++版本低于4.8，那你必须先升级，以前的版本可能还可以屏蔽了C++11的支持，但这个版本的经我验证不行。

fcitx-qt5编译

假设你上述条件都有满足了，安装很容易，下载->配置->cmake->make->make intsall(这步可以不要，但有了新版不把QT4换了你忍得了)

1. 下载fcitx-qt5源码

anzyelay@ubuntu:Downloads$ git clone https://github.com/fcitx/fcitx-qt5.git
anzyelay@ubuntu:Downloads$ cd fcitx-qt5/

2. 设置qmake的环境变量

qmake在你安装的QT的bin目录下，也可以在cmake时指定：

anzyelay@ubuntu:Downloads$ export PATH=/home/anzyelay/Qt5.6.0/5.6/gcc_64/bin/:$PATH

如果不设置好像后面cmake时会出错如下：

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

3.cmake

生成Makefile等相关编译配置，类似于./configure，你可以新建一个目录，在里面cmake使生成的配置都在新建目录里，这要错了也好清除。如下：

anzyelay@ubuntu:build$ mkdir build
anzyelay@ubuntu:build$ cd build
anzyelay@ubuntu:build$ cmake ..

cmake后面的“..”是说要用上层目录中的CMakeLists.txt文件来配置，你只要指明目录，它会自行去寻找CMakeLists.txt文件的。

在这一步你会遇到很多问题，一般都是因为我上面说的几个编译前提条件造成的。我在下面罗列了些自己遇到的，还有别的自行百度之

4. make 和make install

5. copy编译好的插件和库到QT里面，具体参看我原因分析里说的方法。

cmake编译安装：

fcitx-qt5.需要的cmake版本必须是>2.8.12的，所以使用源码安装，你也可以试试直接安装，如果版本太低可以指定如下：

sudo apt-get instsll cmake=2.8.12

实在不行了就老实编译吧。

下载地址

参考安装说明有两种编译方法：

先查看下cmake --version

有旧版：

anzyelay@ubuntu:Downloads$ cd cmake-2.8.12.2/
anzyelay@ubuntu:cmake-2.8.12.2$ cmake .
anzyelay@ubuntu:cmake-2.8.12.2$  make
anzyelay@ubuntu:cmake-2.8.12.2$ make install
anzyelay@ubuntu:cmake-2.8.12.2$ cmake --version
cmake version 2.8.12.2

没有旧版：
```
./bootstrap
make
sudo make install
```

ECM编译安装：

安装它主要是为了获得ECMConfig.cmake这个东西。方法通用的编译安装如下：

下载：

anzyelay@ubuntu:build$ wget https://launchpadlibrarian.net/189487929/extra-cmake-modules_1.4.0.orig.tar.xz
anzyelay@ubuntu:build$ ls
extra-cmake-modules_1.4.0.orig.tar.xz

配置：

anzyelay@ubuntu:build$ tar -Jxf extra-cmake-modules_1.4.0.orig.tar.xz
anzyelay@ubuntu:build$ cd extra-cmake-modules-1.4.0
anzyelay@ubuntu:extra-cmake-modules-1.4.0$ cmake .

编译安装

anzyelay@ubuntu:extra-cmake-modules-1.4.0$ make
anzyelay@ubuntu:extra-cmake-modules-1.4.0$ sudo make install

编译后就得到了我们要的文件ECMConfig.cmake如下:

anzyelay@ubuntu:build$ find . -name ECMConfig.cmake
./extra-cmake-modules-1.4.0/ECMConfig.cmake

libxkbcommon编译安装

libxkbcommon的编译要用到yacc这条命令，先yacc -v或其它命令查看有没有yacc,没有就安装

anzyelay@ubuntu:Qt5.6.0$ which yacc
anzyelay@ubuntu:Qt5.6.0$ sudo apt-get install bison
anzyelay@ubuntu:Qt5.6.0$ which yacc
/usr/bin/yacc

然后开始编译libxkbcommon，

anzyelay@ubuntu:libxkbcommon-0.5.0$ wget http://xkbcommon.org/download/libxkbcommon-0.5.0.tar.xz
anzyelay@ubuntu:libxkbcommon-0.5.0$ tar -Jxf libxkbcommon-0.5.0.tar.xz
anzyelay@ubuntu:libxkbcommon-0.5.0$ cd libxkbcommon-0.5.0/
anzyelay@ubuntu:libxkbcommon-0.5.0$ ./configure
anzyelay@ubuntu:libxkbcommon-0.5.0$ ./configure --disable-x11
anzyelay@ubuntu:libxkbcommon-0.5.0$ make
anzyelay@ubuntu:libxkbcommon-0.5.0$ sudo make install

三 ERROR

cmake 错误：

1. CMake 2.8.12 or higher is required. You are running version 2.8.7

我创建安装目录,进入后执行 cmake +上层目录(如果是在fcitx-qt5/目录下直接cmake . 就行)后出现版本低的错误如下

anzyelay@ubuntu:Downloads$ cd fcitx-qt5/
anzyelay@ubuntu:build$ cmake ..
CMake Error at CMakeLists.txt:1 (cmake_minimum_required):
  CMake 2.8.12 or higher is required.  You are running version 2.8.7

安装高版本的cmake，具体见上面的cmake编译安装

2. Could not find a package configuration file provided by “ECM”

See also "/home/anzyelay/Downloads/fcitx-qt5/build/CMakeFiles/CMakeOutput.log".

出错提示大意是缺少ECM提供的ECMConfig.cmake,ecm-config.cmake两个文件中的任意一个,去下载获得ECM源码,然后解压出来编译安装就行（具体见上面的ECM编译安装）,错误提示也说了只要有两个文件中的一个就行了.如果没安装可以用ECM_DIR指明文件路径

3. need c++ 11 compatible compiler to compile

网上有的直接修改CMakeLists.txt文件，把检查CXX11的语句屏了,虽然CMAKE可行通过了,可后面make时会出问题,毕竟很多函数还是用到了C++11特性的.你也可以试试，或者把-std=c++11改为 -std=c++0x

21 #check_cxx_compiler_flag(“-std=c++11” SUPPORT_CXX11)

22

23 #if(NOT SUPPORT_CXX11)

24 # message(FATAL_ERROR “need c++ 11 compatible compiler to compile”)

25 #endif()

26

27 #set(CMAKE_CXX_FLAGS “${CMAKE_CXX_FLAGS} -std=c++11 -Wall”)

如果出现未定义之类的错误还是升级GCC版本吧.参考网址

查了下fcitx_utils_get_fcitx_path没有譔定义,网上找了下发现在fcitx-libs-dev库中.

安装它,安装时出错,要删除fcitx-frontend-qt5才能安装,因为我前面试着安装过fcitx-frontend-qt5但当时包没找到没安装成功,我还以为没关系,结果影响大大的,今后安装软件时如果不成功最好还是remove –purge下它省得出乱七八槽的事.如下出现的错误，及解决方法

怀疑是GCC4.7版本不行.更新到4.9的版本,再次编译OK了,注意在编译前先把原来的配置和编译的清理下.

编译后拷贝出错

1.原来可以切换输入法了，但清理完编译后的文件后，又无法切换了

原因是相关的库没有COPY过去，解决方法：

把fcitx-qt5-1.0.5文件夹下的dbusaddons 与 widgetsaddons中的动态库全拷贝到

Qt5.6.0/Tools/QtCreator/lib/qtcreator或者Qt5.6.0/5.6/gcc_64/lib下。

两个选一个就行.

2.插件和库都移过去了还是不能切换，甚至于其它软件也不能切换了

重启机子吧，检查下fcitx开启了没，配置下切换快捷键。

时间： 2024-10-01 07:12:40

QT5.6.0无法切换fcitx中文输入法问题记录

一原因分析：

二获得插件的方法

1. 使用apt-get安装

2.自己编译fcitx-qt5安装

编译的前提条件：

fcitx-qt5编译

1. 下载fcitx-qt5源码

2. 设置qmake的环境变量

3.cmake

4. make 和make install

5. copy编译好的插件和库到QT里面，具体参看我原因分析里说的方法。

cmake编译安装：

ECM编译安装：

libxkbcommon编译安装
