Qt5.3及以前的版本:
qt creator插件目录:qt安装目录/Tools/QtCreator/lib/Qt/plugins/platforminputcontexts。
需要的fcitx输入法插件文件:libfcitxplatforminputcontextplugin.so
解决方法:
使用dpkg查找插件文件,fcitx在fcitx-frontend-qt5中,没有就用apt安装即可。
$ dpkg -L fcitx-frontend-qt5 | grep .so
/usr/lib/x86_64-linux-gnu/qt5/plugins/platforminputcontexts/libfcitxplatforminputcontextplugin.so
然后复制这个文件到QT Creator目录:
$ cd qt安装目录/Tools/QtCreator/lib/Qt/plugins/platforminputcontexts/
$ cp /usr/lib/x86_64-linux-gnu/qt5/plugins/platforminputcontexts/libfcitxplatforminputcontextplugin.so .
$ chmod +x libfcitxplatforminputcontextplugin.so
然后重启QT Creator即可输入中文。
---------------------------------------------------------------
编译程序后程序无法输入中文问题,也是缺少插件的原因。
$ cd QT安装目录/5.8/gcc_64/plugins/platforminputcontexts
$ cp /usr/lib/x86_64-linux-gnu/qt5/plugins/platforminputcontexts/libfcitxplatforminputcontextplugin.so .
$ chmod +x libfcitxplatforminputcontextplugin.so
然后重新编译即可。
Qt5.3以上的版本:
Qt5.4以及Qt5.5,旧办法失效,原因是Qt5.4后对之前Qt5版本不再二进制兼容,libfcitxplatforminputcontextplugin.so 需要编译最新的fcitx-qt5。
编译fcitx-qt需要cmake,安装cmake命令,如果已经安装,请略过。
sudo apt-get install cmake
-
安装 fcitx-libs-dev
sudo apt-get install fcitx-libs-dev
-
设置qmake的环境变量:
export PATH="/home/lieefu/Qt5.9.0/5.9/gcc_64/bin":$PATH
-
下载fcitx-libs源码:
git clone git@github.com:fcitx/fcitx-qt5.git
-
编译方法:
cd fcitx-qt5
cmake .
make
sudo make install
最后把编译得到 libfcitxplatforminputcontextplugin.so 拷贝到 Qt5.5安装目录的 Tools/QtCreator/bin/plugins/platforminputcontexts
Qt5.6的目录是 Tools/QtCreator/lib/Qt/plugins/platforminputcontexts
大功告成!

遇到上述错误处里方法:
这个页面 https://launchpad.net/ubuntu/+source/extra-cmake-modules/1.4.0-0ubuntu1 下载 extra-cmake-modules_1.4.0.orig.tar.xz
https://launchpad.net/ubuntu/+source/extra-cmake-modules/5.18.0-0ubuntu1 extra-cmake-modules_5.18.0.orig.tar.xz
解压后:
cd extra-cmake-modules-1.4.0
cmake .

处里方法:
Ubuntu 16.04中可以执行 sudo apt install libxkbcommon-dev 安装
wget http://xkbcommon.org/download/libxkbcommon-0.5.0.tar.xz
tar xf libxkbcommon-0.5.0.tar.xz
./configure —prefix=/usr —libdir=/usr/lib/x86_64-linux-gnu —disable-x11
make
sudo make install
编译libxkbcommon用到yacc,如果没有这个命令,会遇到下面的错误,yacc在 bison软件包中
sudo apt-get install bison
YACC src/xkbcomp/parser.c
./build-aux/ylwrap: line 176: yacc: command not found
make: *** [src/xkbcomp/parser.c] Error 127
