Hi,
I have a Qt4 program that I'm working on and ran into an issue yesterday
with the automoc cpp files. I had added a new slot and connected a
comboxbox currentIndexChanged signal to it but when I ran the program I
could see messages on stdout complaining that my slot didn't exist. I
tracked the problem down to the fact that the moc_ctrlBasic.cpp file was
not being regenerated. If I look in my cmake build directory I currently
have 8 moc cpp files:
./moc_ctrlBasic.cpp
./moc_ctrlmenu.cpp
./moc_infoWin.cpp
./moc_qglDisplay.cpp
./moc_qglMultiWindow.cpp
./moc_qglWindow.cpp
./moc_videoGeneric.cpp
./yuv_player_automoc.cpp
I am using CMake 2.8.10.1 with Visual Studio 11 and when I do a clean
solution these 8 moc cpp files are not deleted. In order to get my new
slot recognised I had to manually delete these moc files and then after a
rebuild everything worked as expected. None of my cpp files #include
"moc_xxx.cpp" but that isn't necessary from my reading of the AUTOMOC
property (i.e. ctrlBasic.cpp only does a #include "ctrlBasic.h"). What am
I doing wrong in my CMakeLists.txt file which looks like this:
cmake_minimum_required(VERSION 2.8.9 FATAL_ERROR)
project(yuv_player)
find_package(OpenGL REQUIRED)
find_package(Qt4 REQUIRED)
set(QT_USE_QTMAIN true)
set(QT_USE_QTOPENGL true)
include(${QT_USE_FILE})
set(CMAKE_AUTOMOC true)
if (MSVC)
add_definitions(/MP) # build in parallel
# disable the security warnings for fopen, scanf etc.
add_definitions(/D"_CRT_SECURE_NO_WARNINGS" /D"_SCL_SECURE_NO_WARNINGS")
endif()
