Qt and cpprestsdk

zombieanfuehrer · December 7, 2020, 5:18pm

Good evening folks,

i am quite a beginner and am just struggling through the correct configuration of CMakeLists.txt files.

I have created a project based on my own file, Qt framework files and cpprestsdk (casablanca) from MS.
For the installation of the cpprestsdk I use conan.

Unfortunately I get several LNK Errors when building the _executable.
The individual libraries can be built without problems.

Here is the CMake output during build all:

@marc.chevrier IIRC, you understand German?

What I think is missing is a Core component in the find_package? It appears that moc is not being run on the MainWindow class somehow?

Hi Ben,

sorry I forgot to translate it :o.
I used set(CMAKE_PREFIX_PATH " … /cmake/Qt5") to my Qt installation dir.
I have read that I do not need find_package cause my enviroment var. of Qt is not fine.

You still need find_package(Qt5) so that CMake knows to look for it.

I think you’re confusing two things though. “Prefixes” and “roots” are the equivalent of CMAKE_INSTALL_PREFIX. I suspect that you want CMAKE_PREFIX_PATH to be the one which contains lib in your … there. What you have is suitable for Qt5_DIR though.

In My CMakelist at the main directory at line 19 (Screenshot) I have the find_package(Qt5 Required Widgets) command

marc.chevrier · December 7, 2020, 7:10pm

Not at all.

You do not use the Qt targets correctly. You must link all libraries to Qt, not just the executable unless you make all libraries STATIC.

Something like this is wrong and indicates the problem:

target_include_directories(${LIBRARY_NAME_3} PUBLIC
"C:/Qt/5.15.1/msvc2019_64/include/QtWidgets"    
"C:/Qt/5.15.1/msvc2019_64/include/QtGui"   
"C:/Qt/5.15.1/msvc2019_64/include/"

This must be replaced by target_link_libraries.

And something like
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_AUTOUIC ON)
should by the top-level for all targets, not just gui.

OK thanks,

i changes my CMakeLists in gui to this:
#.ui File aus dem Qt designer importieren

set(sources "${PROJECT_SOURCE_DIR}/gui/mainwindow.ui" )

#-------Qt-Framework-GUI----------------###################################

add_library(${LIBRARY_NAME_3} OBJECT

     

    "${sources}"   

    "${PROJECT_SOURCE_DIR}/gui/mainwindow.cpp"

       

)

target_link_libraries(${LIBRARY_NAME_3} 

    Qt5::Widgets 

)

And this

set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_AUTOUIC ON)

is now in my top-level CMakeList.

Also I delete the targe_link_libraries

Qt5::Widgets 
Qt5::Core

from my app CMakeList.

But now the compiler does not find the header files anymore e.g. mainwindow.h

I also added this part to the CMakelists.txt in gui:

target_include_directories(${LIBRARY_NAME_2} PUBLIC
"${PROJECT_SOURCE_DIR}/include/"
)

To find the mainwindow.h which is in the include directory.
But also does not work

ben.boeckel · December 7, 2020, 10:39pm

Why would you delete the Qt5:: targets from target_link_libraries? They need to be linked to from any target (library or executable) using Qt5 libraries.
