Trouble getting QPrinter to link using cmake
c++, cmake, qt5, windows
Solution
With CMake 2.8.11:
SET(CMAKE_C_COMPILER E:/Qt/Qt5.2.1/Tools/mingw48_32/bin/gcc.exe)
SET(CMAKE_CXX_COMPILER E:/Qt/Qt5.2.1/Tools/mingw48_32/bin/g++.exe)
cmake_minimum_required(VERSION 2.8.11)
PROJECT (test_prog)
add_definitions(-std=c++11)
SET( test_prog_SRCS test.cpp)
# Tell CMake to run moc when necessary:
set(CMAKE_AUTOMOC ON)
# As moc files are generated in the binary dir, tell CMake
# to always look for includes there:
set(CMAKE_INCLUDE_CURRENT_DIR ON)
find_package(Qt5PrintSupport REQUIRED)
add_executable(test_prog WIN32 ${test_prog_SRCS})
target_link_libraries(test_prog Qt5::PrintSupport)
Problem
So I've been trying to get my programs with QPrinter to work compile with cmake+mingw+qt5.2 but I'm having issues: the following test program doesn't compile because it cant find QPrinter which should be part of QtCore ``` #include <QPrinter> #include <QApplication> #include <windows.h> int main() { QApplication a( argc, argv ); return 0; } // end ``` this is my cmake file ``` SET(CMAKE_C_COMPILER E:/Qt/Qt5.2.1/Tools/mingw48_32/bin/gcc.exe) SET(CMAKE_CXX_COMPILER E:/Qt/Qt5.2.1/Tools/mingw48_32/bin/g++.exe) cmake_minimum_required(VERSION 2.8) PROJECT (test_prog) add_definitions(-std=c++11) SET( test_prog_SRCS test.cpp) # Tell CMake to run moc when necessary: set(CMAKE_AUTOMOC ON) # As moc files are generated in the binary dir, tell CMake # to always look for includes there: set(CMAKE_INCLUDE_CURRENT_DIR ON) # Widgets finds its own dependencies. find_package(Qt5Widgets REQUIRED) find_package(Qt5Core REQUIRED) find_package(Qt5Gui REQUIRED) include_directories( ${Qt5Widgets_INCLUDE_DIRS} ${Qt5Gui_INCLUDE_DIRS} ${Qt5Core_INCLUDE_DIRS} ) add_executable(test_prog WIN32 ${test_prog_SRCS}) target_link_libraries(test_prog ${Qt5Widgets_LIBRARIES} ${Qt5Core_LIBRARIES} ${Qt5Gui_LIBRARIES} ) ``` The Error is: test.cpp:1:20: fatal error: QPrinter: No such file or directory `#include <QPrinter>` Does anyone know the right incantations to get this to work?
