尝试链接到外部静态库。但是QT创建者正在编译外部库源文件

Question

这一切在带有QT创建者4.5.2的Ubuntu 18.04上发生。该项目是QT小部件项目。我想链接到在netbeans中创建的静态链接的C ++库。但是当我建造时QT Creator不仅链接到静态库，它还会编译库（game.cpp）中的文件并生成以下错误。

/ home / bobp040653 / Scrabble / Programming / ScrabbleLib / Game.cpp：9：错误：对`ScrabbleLib :: Game :: TileBag :: tileValues'的未定义引用

我一点都不明白。 Game.o是外部静态链接库的一部分。它在netbeans下可以正常编译。是因为该库是libscrabblelib.a吗？这是QT无法识别的库类型吗？

这是我的项目的.pro文件的副本。

Answer 1

您添加了DEPENDPATH += $$PWD/../ScrabbleLib，它告诉Qt编译文件。
