有人知道为什么吗?该代码在我同事的机器上运行良好。只是不是我的。我多次引用DerivedData,没有用。
按照本指南http://doc-snapshot.qt-project.org/qdoc/qdoc-guide-conf.html,我制作了一个简单的qdoc配置文件.
sourcedirs = ../sources
sources.fileextensions = "*.cpp *.qdoc *.mm *.qml"
headers.fileextensions = "*.h *.ch *.h++ *.hh *.hpp *.hxx"
outputdir = ./doc/
outputformats = HTML

但是,生成的文档文件夹为空,除了索引文件和几个文件夹.

有人可以帮忙解释一下吗?非常感谢!
