QT5.7无法使用中文输入法

2016-11-21 14:06 756 查看
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/Qt5.5.0/5.5/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

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

解压后:

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


CMake Error at /home/lieefu/Qt5.5.0/5.5/gcc_64/lib/cmake/Qt5Gui/Qt5GuiConfigExtras.cmake:9 (message):

  Failed to find "GL/gl.h" in "/usr/include/libdrm".

处里方法:

sudo apt-get install libgl1-mesa-dev libglu1-mesa-dev

CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:108 (message):

  Could NOT find XKBCommon (missing: XKBCommon_LIBRARIES XKBCommon) (Required

处里方法:

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
