Question

在跟随test case example之后，我坚持制作。

我的程序如下。

~/Qt/5.12.2/clang_64/bin/qmake -project "QT +=testlib"
=>它生成了Testcase.pro
~/Qt/5.12.2/clang_64/bin/qmake
=>生成文件
~/Qt/5.12.2/clang_64/bin/moc -o testqstring.moc testqstring.h => testqstring.moc已生成
make => moc_predefs.h和moc_testqstring.cpp生成，并且打印错误如下。

我错了什么？

进行测试Qt测试用例-重复的符号
