环境：
ubuntu 14.04 x64
fcitx五笔拼音输入法
sublime text 2
sublime text的中文输入法问题网上很多解决办法，用来用去都无法实现，后来发现原来是因为本地用的是解压版，没有创建快捷方式，导致启动时引导不上输入法，记录如下：
1、保存以下代码为“sublime-imfix.c”
/*
sublime-imfix.c
Use LD_PRELOAD to interpose some function to fix sublime input method support for linux.
By Cjacker Huang
gcc -shared -o libsublime-imfix.so sublime-imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC
LD_PRELOAD=./libsublime-imfix.so subl
*/
#include <gtk/gtk.h>
#include <gdk/gdkx.h>
typedef GdkSegment GdkRegionBox;
struct _GdkRegion
{
long size;
long numRects;
GdkRegionBox *rects;
GdkRegionBox extents;
};
GtkIMContext *local_context;
void
gdk_region_get_clipbox (const GdkRegion *region,
GdkRectangle*rectangle)
{
g_return_if_fail (region != NULL);
g_return_if_fail (rectangle != NULL);
rectangle->x = region->extents.x1;
rectangle->y = region->extents.y1;
rectangle->width = region->extents.x2 - region->extents.x1;
rectangle->height = region->extents.y2 - region->extents.y1;
GdkRectangle rect;
rect.x = rectangle->x;
rect.y = rectangle->y;
rect.width = 0;
rect.height = rectangle->height;
//The caret width is 2;
//Maybe sometimes we will make a mistake, but for most of the time, it should be the caret.
if(rectangle->width == 2 && GTK_IS_IM_CONTEXT(local_context)) {
gtk_im_context_set_cursor_location(local_context, rectangle);
}
}
//this is needed, for example, if you input something in file dialog and return back the edit area
//context will lost, so here we set it again.
static GdkFilterReturn event_filter (GdkXEvent *xevent, GdkEvent *event, gpointer im_context)
{
XEvent *xev = (XEvent *)xevent;
if(xev->type == KeyRelease && GTK_IS_IM_CONTEXT(im_context)) {
GdkWindow * win = g_object_get_data(G_OBJECT(im_context),"window");
if(GDK_IS_WINDOW(win))
gtk_im_context_set_client_window(im_context, win);
}
return GDK_FILTER_CONTINUE;
}
void gtk_im_context_set_client_window (GtkIMContext *context,
GdkWindow*window)
{
GtkIMContextClass *klass;
g_return_if_fail (GTK_IS_IM_CONTEXT (context));
klass = GTK_IM_CONTEXT_GET_CLASS (context);
if (klass->set_client_window)
klass->set_client_window (context, window);
if(!GDK_IS_WINDOW (window))
return;
g_object_set_data(G_OBJECT(context),"window",window);
int width = gdk_window_get_width(window);
int height = gdk_window_get_height(window);
if(width != 0 && height !=0) {
gtk_im_context_focus_in(context);
local_context = context;
}
gdk_window_add_filter (window, event_filter, context);
}
2、安装 C/C++ 的编译环境和 gtk libgtk2.0-dev
sudo apt-get install build-essential
sudo apt-get install libgtk2.0-dev
3、编译共享内库，生成“libsublime-imfix.so”，把生成的so文件放到sublime根目录
gcc -shared -o libsublime-imfix.so sublime-imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC
4、修改 /usr/bin/subl 为
#!/bin/sh
export LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so
exec /opt/sublime_text/sublime_text "$@"
5、新增“/usr/share/applications/sublime_text.desktop”
[Desktop Entry]
Version=1.0
Type=Application
Name=Sublime_Text
GenericName=Text Editor
Comment=Sophisticated text editor for code, markup and prose
Exec=bash -c 'LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text %F'
Terminal=false

[Desktop Action Window]
Name=New Window
Exec=bash -c 'LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text -n'
OnlyShowIn=Unity;
[Desktop Action Document]
Name=New File
Exec=bash -c 'LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text --command new_file'
OnlyShowIn=Unity;
6、重启。
