    @JonB I've got "#include <windows.h>" inside "mainwindow.h", so shouldn't it be recognised?

    #include <QMainWindow>
    #include <windows.h> // see note 1
    #include <GetCoreTempinfo.h>
    #include <QDebug>
    #include <QString>
    

    I do get a warning about "#include <GetCoreTempinfo.h>"; "non-portable path to file ' <GetCoreTempinfo.h>'; specified path differs in case from file name on disk.

    Thanks,
    Ryan

    So that would look like it makes it OK to compile when included via mainwindow.h, which is fine. But when you ask Creator to read in GetCoreTempinfo.h to view on its own, it might give warnings without windows.h. That's OK, so long as it compiles.

    "#include <GetCoreTempinfo.h>"; "non-portable path to file ' <GetCoreTempinfo.h>'; specified path differs in case from file name on disk.

    You include GetCoreTempinfo.h. I imagine you have saved/copied this file onto disk with e.g. all lower case letters. You will be OK under Windows; you might like to rename the file to match the way it is spelt here anyway, but not vital.

      I see, the header file doesn't match the documentation on the website, typical :)

      So it should be something like this:

      #include <windows.h>
      #include <GetCoreTempinfo.h>
      
      // other stuff in your program
      
      CORE_TEMP_SHARED_DATA ct;
      fnGetCoreTempInfo(&ct);
      qDebug() << "\n\n\nTest: " << QString::number(ct.fTemp[1]);

        @VRonin The Core Temp side seems to be poorly documentated in general!

        The only issue with using "fnGetCoreTempInfo(&ct);" is the following errror.

        ..\..\..\QtProgramming\QtCoreTempTest\QtCoreTempTest\mainwindow.cpp:12:23: error: cannot bind non-const lvalue reference of type 'CORE_TEMP_SHARED_DATA*& {aka core_temp_shared_data*&}' to an rvalue of type 'CORE_TEMP_SHARED_DATA* {aka core_temp_shared_data*}'
        

        It seems that one reference is a *&, and the other is just *; with the following compiler output.

          And this is why I don't like programming in C.

          CORE_TEMP_SHARED_DATA ct;
          CORE_TEMP_SHARED_DATA* pct=&ct;
          fnGetCoreTempInfo(pct);
          qDebug() << "\n\n\nTest: " << QString::number(ct.fTemp[1]);

            @VRonin Yea it's a bit tricky for me coming from C to C++, especially with Windows!

            Everything is getting recognised properly, but there's just one build issue on "fnGetCoreTempInfo(pct);". The error is as follows;

            C:\Users\ariie\Desktop\QtProgramming\QtCoreTempTest\QtCoreTempTest\mainwindow.cpp:13: error: undefined reference to `_imp___Z17fnGetCoreTempInfoRP21core_temp_shared_data'
            

            Thanks again for the responses,
            Ryan

              what are the contents of the CoreTempLib/x86/ folder (I can't trust the docs apparently)?

                  I finally gave up and actually downloaded the library otherwise we'll take forever.
                  They are incompatible with MinGW, good old @SGaist is always right.
                  You need to use Visual Studio or visual studio build tools to link against it

                    @VRonin

                    That was the clue I needed! I changed to kit to MSVC2017 and it started working perfectly, with your modifications!

                    I'll get it all on a GUI, post the project here and mark the topic as solved!

                    I can't thank you enough!

                      @VRonin said in Core Temp Shared Memory in Qt C++ - Windows:

                      good old @SGaist is always right.

                      I know, it's really irritating isn't it? ;-)

                        At least we got there in the end!

                        For anyone else wanting to make a PC monitoring system, I am releasing the full test project for Core Temp Shared Memory below.

                        • Make sure Core Temp is installed & running. I use the following settings: enable plug-ins, start core temp with Windows, start core temp minimized.
                        • You must tick "Enable global shared memory (SNMP)" inside Core Temp advanced settings!
                        • Make sure you're using MSVC compiler; I used 2017 32-bit on Qt 5.14.2, Windows 10 64-bit .
                        • Download the library and put it somewhere useful (No spaces, in a directory with a short file path).
                        • Import the library by right clicking the project; external library, untick Linux & Mac.
                        • Point the library file path to the folder corrosponding to your architecture (x86 or x64), depending on your compiler. Example "C:\CoreTempLib\x86".
                        • Point the include path to the root directory of the library (should have Borland, x64, x86 & GetCoreTempInfo.h inside). Example "C:\CoreTempLib".
                        • Now you can insert the header files "windows.h" and "GetCoreTempInfo.h" and use the library.
                                    CORE_TEMP_SHARED_DATA* pct=&ct;
                                    fnGetCoreTempInfo(pct);
                        
                        qDebug() << "Core 0 Temperature: "<< ct.fTemp[0] << " C.";
                        

                        f78f9358-9b96-4b7f-acee-ba8452ab49ab-image.png

                        I made this quick project with C++/XML. It uses QThread and grabs the CPU data every second and pushes it to the GUI, without blocking it. Some of the code is messy, but it's just a quick example so other people don't have to go through this! If I've done anything dramatically wrong (like use Mutex incorrectly), I'm not sure if people can still post on this topic after I mark it as solved, so just PM me and I should be able to make the edits. Feel free to use any of the code below however you want.

                        I'd like to say a big thank you to @SGaist, @JonB & especially @VRonin. I'd probaly still be scratching my head, wondering why the structure still isn't being populated without you guys!

                          At least we got there in the end!

                          For anyone else wanting to make a PC monitoring system, I am releasing the full test project for Core Temp Shared Memory below.

                          • Make sure Core Temp is installed & running. I use the following settings: enable plug-ins, start core temp with Windows, start core temp minimized.
                          • You must tick "Enable global shared memory (SNMP)" inside Core Temp advanced settings!
                          • Make sure you're using MSVC compiler; I used 2017 32-bit on Qt 5.14.2, Windows 10 64-bit .
                          • Download the library and put it somewhere useful (No spaces, in a directory with a short file path).
                          • Import the library by right clicking the project; external library, untick Linux & Mac.
                          • Point the library file path to the folder corrosponding to your architecture (x86 or x64), depending on your compiler. Example "C:\CoreTempLib\x86".
                          • Point the include path to the root directory of the library (should have Borland, x64, x86 & GetCoreTempInfo.h inside). Example "C:\CoreTempLib".
                          • Now you can insert the header files "windows.h" and "GetCoreTempInfo.h" and use the library.
                                      CORE_TEMP_SHARED_DATA* pct=&ct;
                                      fnGetCoreTempInfo(pct);
                          
                          qDebug() << "Core 0 Temperature: "<< ct.fTemp[0] << " C.";

                          I made this quick project with C++/XML. It uses QThread and grabs the CPU data every second and pushes it to the GUI, without blocking it. Some of the code is messy, but it's just a quick example so other people don't have to go through this! If I've done anything dramatically wrong (like use Mutex incorrectly), I'm not sure if people can still post on this topic after I mark it as solved, so just PM me and I should be able to make the edits. Feel free to use any of the code below however you want.

                          I'd like to say a big thank you to @SGaist, @JonB & especially @VRonin. I'd probaly still be scratching my head, wondering why the structure still isn't being populated without you guys!

                          @Ryan-R said in Core Temp Shared Memory in Qt C++ - Windows:

                          For anyone else wanting to make a PC monitoring system, I am releasing the full test project for Core Temp Shared Memory below.

                          All looks good! I don't get hardware/devices, so this is novel for me. Is this used for measuring my core temperature to see if I have virus or something?

                            Well originally I used LabVIEW and created this:

                            692aa16c-6c00-4f79-be97-2dcfa011b58f-image.png

                            The aim was to create a program that sticks to the Desktop and can be overlayed on top of games. The issue with LabVIEW is that the runtime engine is quite bloated, so running that program with 4K games wasn't an option without losing FPS.

                            My plan is to re-create the program in Qt C++ with XML and CSS.

                            I'm sure there are a few other gamers out there that are curious about making something like this, since you can get it to display warnings, Windows notifications, ect.. with Qt.

                            I'm also going to hook it up to my dedicated server with MySQL, so all of the data collected gets logged to a web panel. Then I can make a "lite" version of the program on my companies embedded PCs around the world for real-time data logging, remote control and firmware updates.
