Turn to Memo.

System CentOS7.3 FCITX Chinese Input method. The previous article describes how to install the Chinese input method on CentOS7.

This article is to solve the problem of unable to enter Chinese in sublime after installing the FCITX Chinese input method. Reprint the following articles for your memo.

Test system: Ubuntu 12.10 (theoretically all Linux distributions are generic)

Input Method: Fcitx 4.2.6.1

Sublime text version: Sublime text 3 dev (Build 3026)

--------------------------------------------------------------------

My Computer Configuration is: linuxMint17.1

Input Method: Sogou Input Method

Sublime text version: Sublime text 3

1. Save the following code as asublime-imfix.cfile

 
/*
sublime-imfix.c
Use LD_PRELOAD to interpose some function to fix sublime input method support for linux.

gcc -shared -o libsublime-imfix.so sublime-imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC

typedef GdkSegment GdkRegionBox;

struct _GdkRegion

}

2. Install the C + + compiler environment and GTK Libgtk2.0-dev

sudo Install build-essentialsudoinstall libgtk2. 0-dev

3. Compiling a shared internal library

gcc -shared-o libsublime-imfix.so sublime-imfix.c 'pkg-config --libs--cflags gtk+-2.0 '- FPIC

4. Set ld_preload and start Sublime Text

Ld_preload=./libsublime-imfix.so Subl

5. Change/usr/share/applications/sublime_text.desktopto

 
[Desktop Entry]
[...]
Exec=env LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text %F
[...]

[Desktop Action Window]
[...]
Exec=env LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text -n
[...]

[Desktop Action Document]
[...]
Exec=env LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text --command new_file
[...]

Don't forget to put itlibsublime-imfix.so/opt/sublime_text/in the middle

6. Change/usr/bin/sublto

#!/bin/sh

Export ld_preload=/opt/sublime_text/libsublime-imfix.so
Exec/opt/sublime_text/sublime_text "[Email protected]"

Restart the computer, you can see sublime can input Chinese.
