本文档2019年1月23日修正,Ubuntu18.10,Qt5.12.0测试通过
本文档2017年6月1日修正,Ubuntu16.04,Qt5.9.0测试通过
2016年6月8日修正,ubuntu 16.04 Qt5.7.0 以及 Qt5.6.1均测试通过
在Qt5.3之前,我发布过解决办法 解决Qt5 Creator无法切换输入法(fcitx),不能录入汉字问题,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。如果你懒得自己编译,可以下载我编译的 libfcitxplatforminputcontextplugin.so
看fcitx-qt5项目的更新日志,是在1.0.3版本时解决的这个问题,写本篇博客时,我git clone到的是1.0.4版本。
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/Qt5.12.0/5.12.0/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!
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!
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 .
make
sudo make install

处里方法:
sudo apt-get install libgl1-mesa-dev libglu1-mesa-dev

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
