Linux版的Google Earth從發行以來,中文的顯示一直都不能隨裝即用。一個主要的原因在於它用的圖形介面程式庫是它所附帶,32位元的QT動態程式庫。因為不是使用者系統中所的QT動態程式庫,使用者不能用qtconfig來更正中文字形。這一點,在一般32位元的Linux系統上,可以用系統中已安裝的動態程式庫(libQT*.so檔們)來取代,詳細步驟可以參考[1]。在64位元的系統上,由於系統中的32位元相容程式庫常有不全(如debian sid的libQtWebKit.so),單純的刪去附帶的版本會造成程式無法啟動。這時,可以試著用[1]中打包好的檔案來跑看看。但如果還是動不了,要自行補全所有的程式庫可能要費好一些功夫。
gltk is a C++ Widget library built on GLUT. The API of gltk is modeled after gtkmm, the C++ interface of the GTK+ library. The implementation of gltk was inspired by GLUI. By building on GLUT, the library is readily ported to platforms where GLUT (or FreeGLUT) is available. These include Linux, Windows, and Mac OS X.
I prefer to indent my code with TABs. Some people do not like that because a TAB can represent different amount of spaces in different editors or viewers. However, I like TABs for their semantic meaning of levels of grouping. How a code editor or viewer displays this grouping information should be left to the liking of its user. And, using two spaces (or four) is just wasting an extra character when we can just set the TAB size to 2 (or 4). I also favor compactness and readability. It's desirable to make the code visually shorter as long as it remains readable.
C++0x was approved by ISO. It adds a great amount of new features to an already-rich language. This very fact has drawn some criticism. And, yet there are still unsatisfied demands for features.
