找不到 qgsapplication.h 和其他头文件

Question

我正在使用 QtCreator 和 QGIS 2.6 构建一个独立的 C++ 应用程序。

我遇到的问题是项目找不到所有必要的头文件。

我的 .pro 文件如下所示：

QT += core gui xml
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = TestQgis2
TEMPLATE = app
SOURCES += main.cpp
#HEADERS +=YOUR HEADERS
#FORMS += YOUR FORMS
#RESOURCES += images/images.qrc

win32:CONFIG(Release, Debug|Release) {
 LIBS += -L"C:/Program Files (x86)/QGIS Brighton/lib/" -lQtCore4
 LIBS += -L"C:/Program Files (x86)/QGIS Brighton/lib/" -lQtGui4
 LIBS += -L"C:/Program Files (x86)/QGIS Brighton/lib/" -lQtXml4
 LIBS += -L"C:/Program Files (x86)/QGIS Brighton/apps/qgis/bin/" -lqgis_core
 LIBS += -L"C:/Program Files (x86)/QGIS Brighton/apps/qgis/bin/" -lqgis_gui
}
else:win32:CONFIG(Debug, Debug|Release) {
 PRE_TARGETDEPS += C:/Program Files (x86)/QGIS Brighton/lib/QtCored4.lib
 PRE_TARGETDEPS += C:/Program Files (x86)/QGIS Brighton/lib/QtGuid4.lib
 PRE_TARGETDEPS += C:/Program Files (x86)/QGIS Brighton/lib/QtXmld4.lib
 LIBS += -L"C:/Program Files (x86)/QGIS Brighton/lib/" -lQtCored4
 LIBS += -L"C:/Program Files (x86)/QGIS Brighton/lib/" -lQtGuid4
 LIBS += -L"C:/Program Files (x86)/QGIS Brighton/lib/" -lQtXmld4
 LIBS += -L"C:/Program Files (x86)/QGIS Brighton/apps/qgis/bin/" -lqgis_core
 LIBS += -L"C:/Program Files (x86)/QGIS Brighton/apps/qgis/bin/" -lqgis_gui
}
win32:{
 INCLUDEPATH += C:/Program Files (x86)/QGIS Brighton/include
 DEPENDPATH +=  C:/Program Files (x86)/QGIS Brighton/include
# INCLUDEPATH += C:/OSGeo4W/apps/qgis-dev/include
# DEPENDPATH += C:/OSGeo4W/apps/qgis-dev/include
 DEFINES += GUI_EXPORT=__declspec(dllimport) CORE_EXPORT=__declspec(dllimport)
}
unix {
 LIBS += -L/usr/local/lib/ -lqgis_core -lqgis_gui
 LIBS += -L/usr/local/lib/qgis/plugins/ -lgdalprovider
 INCLUDEPATH += /usr/local/include/qgis
 DEFINES += GUI_EXPORT= CORE_EXPORT=
}

在我的程序中，找不到以下标题：

#include ""

#include ""

#include ""

#include ""

#include ""

#include ""

并且从安装的qgis文件夹中，我找不到上述任何头文件。

感谢任何帮助。

要调试您的应用程序，我认为您必须在项目文件中添加 RelWithDebInfo 模式：

QT += core gui xml
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = TestQgis2
TEMPLATE = app
SOURCES += main.cpp
#HEADERS +=YOUR HEADERS
#FORMS += YOUR FORMS
#RESOURCES += images/images.qrc

win32:CONFIG(Release, Debug|Release, RelWithDebInfo) {
 LIBS += -L"C:/OSGeo4W/apps/qgis/lib/" -lQtCore4
 LIBS += -L"C:/OSGeo4W/apps/qgis/lib/" -lQtGui4
 LIBS += -L"C:/OSGeo4W/apps/qgis/lib/" -lQtXml4
 LIBS += -L"C:/OSGeo4W/apps/qgis/bin/" -lqgis_core
 LIBS += -L"C:/OSGeo4W/apps/qgis/bin/" -lqgis_gui
}
else:win32:CONFIG(Debug, Debug|Release, RelWithDebInfo) {
 PRE_TARGETDEPS += C:/OSGeo4W/lib/QtCored4.lib
 PRE_TARGETDEPS += C:/OSGeo4W/lib/QtGuid4.lib
 PRE_TARGETDEPS += C:/OSGeo4W/lib/QtXmld4.lib
 LIBS += -L"C:/OSGeo4W/lib/" -lQtCored4
 LIBS += -L"C:/OSGeo4W/lib/" -lQtGuid4
 LIBS += -L"C:/OSGeo4W/lib/" -lQtXmld4
 LIBS += -L"C:/OSGeo4W/apps/qgis/bin/" -lqgis_core
 LIBS += -L"C:/OSGeo4W/apps/qgis/bin/" -lqgis_gui
}
win32:{
 INCLUDEPATH += C:/OSGeo4W/include
 DEPENDPATH +=  C:/OSGeo4W/include
# INCLUDEPATH += C:/OSGeo4W/apps/qgis/include
# DEPENDPATH += C:/OSGeo4W/apps/qgis/include
 DEFINES += GUI_EXPORT=__declspec(dllimport) CORE_EXPORT=__declspec(dllimport)
}
unix {
 LIBS += -L/usr/local/lib/ -lqgis_core -lqgis_gui
 LIBS += -L/usr/local/lib/qgis/plugins/ -lgdalprovider
 INCLUDEPATH += /usr/local/include/qgis
 DEFINES += GUI_EXPORT= CORE_EXPORT=
}

第 28 行是哪一个？

如果是这样的话：

win32:CONFIG(Release, Debug|Release, RelWithDebInfo)

您可以将其替换为：

win32:CONFIG(Release, RelWithDebInfo|Release)

并替换它：

else:win32:CONFIG(Debug, Debug|Release, RelWithDebInfo)

与：

else:win32:CONFIG(RelWithDebInfo, RelWithDebInfo|Release)

因为 Qgis ant Qt 库是用 Release 模式编译的，所以如果你想调试你的应用程序，你必须使用 RelWithDebInfo 模式
