проблемы с компоновщиками с qt4 и CMake

Question

Я пытаюсь выполнить проект Qt (Qt 4.8.6) с CMake, но у меня есть некоторые проблемы с компоновщиком, и я немного потерян.

Вот что я получаю, когда я делать "делать" в моем проекте:

chasselas:build tfaux$ make VERBOSE=1

    NOTE: a missing vtable usually means the first non-inline virtual member function has no definition.

Вот это addressbook.h: http://qt-project.org/doc/qt-4.8/tutorials-addressbook-fr-part1-addressbook-h.html

Вот это adressebook.cpp: http://qt-project.org/doc/qt-4.8/tutorials-addressbook-fr-part1-addressbook-cpp.html

Вот CMakeLists.txt:

CMAKE_MINIMUM_REQUIRED(VERSION 2.8) 
LIST(APPEND CMAKE_PREFIX_PATH "/usr/local/Cellar/qt/4.8.6") 

#Test Cmake file for Qt applications 
SET(PROJECT_NAME addressbook) 
PROJECT(${PROJECT_NAME}) 
Find_PACKAGE(Qt4 REQUIRED) 
SET(QT_USE_MAIN true) 

#Setting the sources of the project 
SET(PROJECT_SOURCES 
main.cpp 
addressbook.cpp 
) 

SET(PROJECTS_HEADERS 
main.h 
addressbook.h 
) 

#Traitement du moc Qt 
QT4_WRAP_CPP(PROJECT_HEADERS_MOC ${PROJECT_HEADERS}) 

#inclusions 
INCLUDE_DIRECTORIES(${TULIP_INCLUDE_DIR} ${QT_INCLUDES} ${CMAKE_CURRENT_BINARY_DIR}) 
INCLUDE(${QT_USE_FILE}) 
ADD_DEFINITIONS(${QT_DEFINITIONS}) 

#creation de l'executable et liaison des librairies 
ADD_EXECUTABLE(addressbook ${PROJECT_SOURCES} ${PROJECT_HEADERS_MOC}) 
TARGET_LINK_LIBRARIES(addressbook ${QT_LIBRARIES} ${QT_NETWORK_LIBRARY}) 
INSTALL(TARGETS addressbook DESTINATION bin) 

Любая помощь приветствуется, спасибо!

Answer 1

1. Используйте команды нижнего регистра в вашем коде cmake. Это гораздо более читаемо.

2. У вас есть опечатка. Вы устанавливаете переменную PROJECTS_HEADERS, но вы передаете PROJECT_HEADERS в qt4_wrap_cpp. Предпочитаете использовать редактор, который делает это очевидным, выделяя идентичные строки при выборе. Фиксирование опечатки исправляет вашу ошибку.

3. Используйте CMAKE_AUTOMOC вместо qt4_wrap_cpp. http://www.cmake.org/cmake/help/v3.0/manual/cmake-qt.7.html Он доступен с CMake 2.8.6.
