如何安装 X11 Xevie 扩展来编译基于 Xevie 的程序

有没有命令来安装谢维（用于 X11 编程）来自存储库？

（以便Xevie.h可以进行编程）

我需要它来在 Qt Creator 中编译此示例：

/* xeviedemo.c */
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <X11/Xlib.h>
#include <X11/Xproto.h>
#include <X11/X.h>
#include <X11/extensions/Xevie.h>
#include <X11/Xutil.h>


static void
print_key_event (XEvent *ev)
{
    XKeyEvent *key_ev;
    char buffer[20];
    int bufsize = 19;
    KeySym key;
    XComposeStatus compose;
    int char_count;

    key_ev = (XKeyEvent *)ev;

    printf ("        State: %x KeyCode: %x\n", key_ev->state & ShiftMask, key_ev->keycode);
    char_count = XLookupString(key_ev, buffer, bufsize, &key, &compose);
    buffer[char_count] = '\0';
    printf ("        Char Count: %d KeySym: %x char: |%c|\n", char_count, key, buffer[0]);
}

int
main(int argc, char **argv)
{
    Display *dpy;
    int major, minor;
    XEvent  event;
    XClientMessageEvent *xcme;
    int count = 0;
    long delay = 0;
    int ret;

    if (argc > 2)
    {
        printf ("Usage: xeviedemo delay (in milliseconds)\n");
        exit(1);
    }
    else if (argc == 2)
    {
        delay = strtol(argv[1], 0, 0);
    }
    printf("Delay is %d milliseconds\n", delay);
    delay *= 1000;

    dpy = XOpenDisplay(NULL);
    XevieQueryVersion(dpy, &major, &minor);
    printf("major = %d, minor = %d\n", major, minor);
    if(XevieStart(dpy))
        printf("XevieStart(dpy) finished \n");
    else
    {
        printf("XevieStart(dpy) failed, only one client is allowed to do event interception\n");
        exit(1);
    }

    XevieSelectInput(dpy, KeyPressMask | KeyReleaseMask |
                     ButtonPressMask | ButtonReleaseMask | PointerMotionMask);

    while(1)
    {
        XNextEvent(dpy, &event);
        xcme = (XClientMessageEvent *)&event;
        /* for readOnly users, send events back to Xserver immediately */
        printf("(%4d)", count++);
        switch(event.type)
        {
        case KeyPress:
            usleep(delay);
            printf(" KeyPress\n");
            print_key_event (&event);
            break;
        case KeyRelease:
            printf(" KeyRelease\n");
            break;
        case ButtonPress:
            usleep(delay);
            printf(" ButtonPress\n");
            break;
        case ButtonRelease:
            printf(" ButtonRelease\n");
            break;
        case MotionNotify:
            printf(" MotionNotify\n");
            break;
        case ClientMessage:
            printf("ClientMessage: <%s>\n", &xcme->data.b[1]);
            break;
        default:
            printf(" unknown event %x\n", event.type);
            break;
        }
        XevieSendEvent(dpy, &event, XEVIE_UNMODIFIED);
        if(count > 10000)
        {
            break;
        }
    }
    XevieEnd(dpy);
    printf("XevieEnd(dpy) finished \n");
    exit(0);
}

我认为没有任何软件包提供Xevie.h。有另一个库称为，xevie.h由提供，libxcb-xevie0-dev但这不是您所需要的。

然而我发现这一页它包含看起来像源包的内容。我尝试下载libXevie-1.0.3.tbz，可以确认它包含一个名为的文件Xevie.h，其中包含您评论中的函数。事实上，文件太小了，我在这里重现了整个内容：

当查找特定文件时，您可以在以下位置搜索http://packages.ubuntu.com或使用apt-file：

$ apt-file search xevie.h
libxcb-xevie0-dev: /usr/include/xcb/xevie.h

如您所见，使用apt-file search filename将返回提供该文件的包（如果有）。如果apt-file没有安装，则需要在运行它之前安装它并生成其包列表：

sudo apt-get install apt-file
sudo apt-file update

2009 年，Xorg 在 X11R7.5 中取消了对 Xevie 的支持自从它已经坏了一段时间了，没有人需要它或有兴趣修理它。即使您找到了构建客户端的库和头文件，它们也无法与任何最新的 Xorg 服务器一起工作。
