使用 QtCreator(qmake) 编译 wtwithqt 示例

Question

我正在使用Qt 开发一个网络管理应用程序，我选择将Wt 用于 UI，因为使用它我不必处理任何 Web 部件（PHP、AJAX、HTML/CSS）和它可以在所有平台上使用。

我成功地使用 cmake 编译和运行示例。虽然我习惯了 QtCreator IDE 和 qmake，但我更愿意将其用于开发和编译。

我在尝试在 QtCreator(qmake) 中编译 "wtwithqt" 示例时遇到了困难。 我一直在到处寻找如何使用 qmake 编译它的指南。但是我发现没有任何帮助。

这是我的 .pro 文件。

testWt.pro

QT += core
QT -= gui

TARGET = helloqt
CONFIG += console no_keywords
CONFIG -=app_bundle

TEMPLATE = app

INCLUDEPATH += lib

LIBS += -lwt -lwthttp -lboost_signals -lboost_system -lboost_regex

QMAKE_CXXFLAGS += -DNDEBUG

HEADERS += \
    QtObject.h \
    HelloApplication.h

SOURCES += \
    hello.cpp \
    QtObject.cpp

编译输出

感谢任何帮助！提前致谢！

您的makefile 非常好，但我认为您忘记链接wtwitqt 互操作层。将-lwtwithqt 添加到LIBS 行，
