現象：

今天在銀河麒麟操作系統上編譯Qt 寫的程序，報如下 錯誤：

QFontDatabase: Cannot find font directory /home/tgm/qt/qt_sdk/lib/fonts. Note that Qt no longer ships fonts. Deploy some (from http://dejavu-fonts.org for example) or switch to fontconfig.

分析原因：這是因為沒有Qt安裝目錄下沒有字體文件導致的，我的Qt安裝目錄為：

/usr/local/Qt 5.9.2

字體目錄一般在Qt安裝目錄下的lib/fonts下即：

/usr/local/Qt 5.9.2/lib/fonts

解決方法：

找一個安裝了windows操作系統的機器，將其字體庫（一般在C:\Windows\Fonts目錄下，有的還很大，幾百兆吧）拷貝到/usr/local/Qt 5.9.2/lib/fonts目錄或者系統字體目錄，如：我的銀河麒麟操作系統字體存放目錄為：

/usr/share/fonts

然后執(zhí)行：

sudo vim /etc/profile

在其后加入如下代碼：

export QT_QPA_FONTDIR=/usr/share/fonts

或

/usr/local/Qt 5.9.2/lib/fonts

重啟系統即可。

注意：windows下的字體庫很大，我的444MB，對于嵌入式的、磁盤空間有限的情況，請根據你要的字體進行刪減，以節(jié)約空間。
