Qt：可執行文件不會重新生成

我有簡單的Qt程序。當運行make它給誤差是1200線長Qt：可執行文件不會重新生成

QThread是可執行文件。當我刪除它並再次運行make時，它編譯成功。但是，當我做一些更改make給我同樣的錯誤。我正在使用qmake創建Makefile，爲什麼可執行文件不會重新生成？

在我看來，你的編輯器以解析器不支持的模式保存文件。檢查保存選項。 – lapk

你可以發佈.pro文件的內容嗎？它看起來可能是編譯器試圖編譯.o文件，就好像它是C++源代碼一樣。 .pro文件應包含程序中的.cpp文件列表，而不是.o文件。另外命名可執行文件QThread可能不明智，因爲這也是Qt類的名稱;也許這是混淆了qmake/make系統中的某些東西。 –

@JeremyFriesner我改變了程序名稱，它的工作原理，謝謝。 – Ashot

你mythread.h確實#include <QThread>，當你自己的可執行文件被命名爲QThread，這個發現你剛剛建立，而不是Qt的自己的頭可執行文件。

您已經重命名了該程序以迴應Jeremy的評論，並且您已經看到它可以正常工作。這是一個很好的選擇。另一種方法是確保包含<QThread>而不是"QThread"（如果您還沒有這樣做），並確保您的編譯器標記已設置爲在Qt的頭文件目錄之前不搜索當前目錄。
