A40I运行QT程序出现以下问题该如何解决？

warren

No file found for "image/png.xml" , even though update-mime-info said it would exist.
Either it was just removed, or the directory doesn't have executable permission... ("/usr/share/mime")

缺少image/png.xml文件或者没权限

在 /usr/share/mime 下面创建目录  image, 然后在里面导入png.xml文件，内容如下：
<?xml version="1.0" encoding="utf-8"?>
<mime-type xmlns="http://www.freedesktop.org/standards/shared-mime-info" type="image/png">
