我在 32 位 Fedora Core 9 机器上静态构建了 X11R5 库。然后我构建了一个使用 X11 的应用程序并静态链接它。到目前为止，一切都很好。 ldd 报告它是一个静态链接的应用程序。我在本地运行就可以了。但是当我将其复制到 64 位 FC9 机器时，失败如下:
assistant.static: xcb_io.c:228: _XSend: 断言 `!dpy->xcb->request_extra' 失败。
已中止
当我运行 strace 时，它似乎试图打开 libXfixes.so:

我不明白为什么静态链接的应用程序会尝试打开共享的 X 库。难道运行应用程序所需的所有内容都不应通过静态链接包含在内(当然应用程序进行的任何 Linux 系统调用除外，这些调用需要在外部处理)。
感谢您的解释!
最佳答案
X11 动态加载库，并且可能加载 64 位库而不是 32 位版本。
在运行时加载模块是正常的 - 就像加载插件或驱动程序时一样。而且由于模块是动态链接到 X11 本身的，因此您会发现自己陷入困境。
就我个人而言，我从来没有幸运地静态链接过 X11 - 您真的需要吗？
