Could not find a configuration file

Kais Ahmad

Hello, I am still fairly new to working with Qt and am currently running into an issue. I am trying to build kArchive using these docs but keep running into issues. After some debugging I found out that I needed to downgrade Qt to version 6.5.0 so I did that. After running the command: `cmake . -G “NMake Makefiles” -DCMAKE_INSTALL_PREFIX=C:Qt release -DCMAKE_BUILD_TYPE=release -DCMAKE_PREFIX_PATH=C:Qt release;C:Qt.

I get this error:

Installing in C:/kderoot. Run C:/Nextcloud/karchive/build/prefix.sh to set the environment for KArchive.

Does anyone have any idea what I am doing wrong and how to fix the issue? Thanks!

Looks like glibc headers are missing,

Kais Ahmad

@Axel-Spoerl Just to double-check. glibc headers are Linux-specific, are they not? I'm using a Windows machine to build

Axel Spoerl

Well, we don’t know what you build where, unless you show some code.

Kais Ahmad

My bad!

ECMQueryQt.cmake
This file normally already errors out becuase it can't find the Qt6paths executable. I have added the QUERY_EXECUTABLE manually

Code:

function(ecm_query_qt result_variable qt_variable)
    set(options TRY)
    set(oneValueArgs)
    set(multiValueArgs)

    cmake_parse_arguments(ARGS "${options}" "${oneValueArgs}" "${multiValueArgs}" ${ARGN})

    set(QUERY_EXECUTABLE "C:/Qt/6.5.0/msvc2019_64/bin/qtpaths.exe")

    if(NOT EXISTS ${QUERY_EXECUTABLE})
        if(ARGS_TRY)
            set(${result_variable} "" PARENT_SCOPE)
            message(STATUS "No ${_exec_name_text} executable found. Can't check ${qt_variable}")
            return()
        else()
            message(FATAL_ERROR "No ${_exec_name_text} executable found. Can't check ${qt_variable} as required")
        endif()
    endif()

    execute_process(
        COMMAND ${QUERY_EXECUTABLE} ${_cli_option} "${qt_variable}"
        RESULT_VARIABLE return_code
        OUTPUT_VARIABLE output
    )

    if(return_code EQUAL 0)
        string(STRIP "${output}" output)
        file(TO_CMAKE_PATH "${output}" output_path)
        set(${result_variable} "${output_path}" PARENT_SCOPE)
    else()
        message(WARNING "Failed call: ${QUERY_EXECUTABLE} ${_cli_option} ${qt_variable}")
        message(FATAL_ERROR "${_exec_name_text} call failed: ${return_code}")
    endif()
endfunction()

And this is included in my CMakeLists.txt:

set(REQUIRED_QT_VERSION 6.5.0)
find_package(Qt6Core ${REQUIRED_QT_VERSION} REQUIRED NO_MODULE)

(It could be that I am currently looking at the wrong place completely wrong. For that I apologize in advance! I need to build and compile an open-source program but there is little up to date information on this online)

@Kais-Ahmad said in Could not find a configuration file:

set(REQUIRED_QT_VERSION 6.5.0)

you might want to comment it out or adjust to cover your Qt version. Just be aware, developers might've put that for a reason.

Kais Ahmad

@artwaw That's the weird part.. 6.5.0 is installed. (https://ibb.co/6rQRy4J). I'm going to try removing the check in a moment and then come back here.

@Kais-Ahmad Are you by any chance mixing MSVC and MinGW? MinGW Qt build requires GLibC.
