试图链接到外部静态库。 但是QT creator正在编译外部库源文件

Question

这一切都发生在 Ubuntu 18.04 上，QT Creator 4.5.2。 该项目是一个 QT 小部件项目。 我想链接到在 netbeans 中创建的静态链接的 C++ 库。 但是当我构建时，QT Creator 并不仅仅链接到静态库，它还会编译库（game.cpp）中的一个文件并生成以下错误。

/home/bobp040653/Scrabble/Programming/ScrabbleLib/Game.cpp:9：错误：未定义对`ScrabbleLib::Game::TileBag::tileValues'的引用

我完全不明白这一点。 Game.o 是外部静态链接库的一部分。 它在 netbeans 下编译得很好。 是不是因为库是 libscrabblelib.a？ 这是 QT 不理解的库类型吗？

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。
