Can't compile #210

Closed Trikos closed 4 years ago

Trikos commented 4 years ago

Hi, Im trying to use your library but I cant compile. Can you help me? I tried to download the source code and using include(path/to/.pri) into my project without doing nothing and QT said unknown qmqtt module found. I tried to open the qmqtt-master/src/qmqtt.pro and compile for winx64 and I get some error during compilation (I set CONFIG += QMQTT_NO_SSL; CONFIG += NO_UNIT_TESTS) What can I do in order to use it? Im developing an Android app and I want to insert this mqtt inside it. Thank you

Using the .pri file is not going to work. At best it will compile the QMQTT source and give you a bunch of errros regarding dll linkage (when compiling for windows).

The usual way to compile is to use qmqtt.pro in the root of the repo. You need to have perl installed to do this. After compilation deploy the project. It should install within your QT distribution. When this is done you should be able to use 'QT += qmqtt' in your own .pro file.

If this does not work out for you, please show us the compiler output.

Wow. I installed PEARL, then open the root .pro file. Select Win64x, compiled and deployed. No error at all. No the debug folder has been created. I opened my project I put qmqtt in .pro and same error. Unknow module. Maybe I had to include something or link the library in some way? Thank you for helping

The problem is probably with the 'deploy' step. I guess you're using QT creator to do this. It appears that the default deploy step does not copy any files to the QT installation directory. I had a custom one in my project, so it worked on my system.

The safest way to 'deploy' the project is to open a command prompt and go to the build directory created by qt-creator (this is the one you showed in your screenshot). Run the command nmake install there. This should copy all project files to the QT installation directory. This is the directory where the QT itself has been installed. (By default it's c:\qt if I'm not mistaken).

Before trying to compile your own code, please check if the files have been copied properly. Assuming your QT installation directory is c:\qt the qmqtt headers should be present in c:\qt\5.13.2\msvc2017_64\include\QtQmqtt.

If that is OK, you should be able to compile your own code. I tried all this with a small test project, and the first time I tried I also got the 'qmqtt.h' not found error while compiling. After restart QT creator the error mysteriously disappeared. It seems QT creator is caching some information, maybe as part of their 'kits'.

Im using qt creator. So after these steps I can also use qmqtt in android compilation right?

ejvr commented 4 years ago

For android compilation you need to setup an 'kit' within qt creator to cross compile to android (to do that you probably need the android SDK and the android QT binaries). If you use win64 it will compile for windows only.

I tried to move on my directory but using nmake install is not recognized as internal command and I havent Linux installed. I tried to look for nmake.exe into Microsoft VC 2019 but nothing. I look into "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community". I found one here "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.27.29110\bin\Hostx64\x86\nmake.exe"

ejvr commented 4 years ago

My bad. You have to use the 'x64 Native Tools Command Prompt for VS 2019' (or whatever visual studio version you are using). That will create a command shell with the proper settings. You can find that command prompt in the 'Visual Studio 2019' folder in the start menu.

Well I did. It compiled. Let me show you what is inside the folder image It seems everything ok, so I created a new project, inserted QT += qmqtt, run qmake everything fine, then moved to the main and this happened image C:\Documents\mqtttest\main.cpp:5: error: 'qmqtt.h' file not found C:\Documents\mqtttest\main.cpp:13: error: use of undeclared identifier 'QMQTT' I tried to remove the kit x64, restart qt but nothing. This is my .pro image

Regarding Android I have everything setted but I dont know how to move in order to compile the library and then use it. Thank you again, super helpful

ejvr commented 4 years ago

The error message 'qmqtt.h' makes sense, because the QtQmqtt directory should include far more files than just QtQmqttDepends. One of them should be qmqtt.h. So I guess the nmake install command somehow failed.

If you try to build again in the visual studio command prompt and run nmake install. On my system I get output like this (this is only part of the output). I guess on your system part not all copy actions are performed or they fail somehow.

I tried multiple times but only that one file appear in my folder. I have some other inside the bin folder. When compiling I have more strings than before. Can you show me what files would be inside the folders QtQmqtt? Also is complicated to compile for Android because I will use it on Android instead of Win. Thank you image

I tried another library qt/mqtt and I did the same stuff, build for WIN then using the tool compiled with nmake install and on the cmd more stuff appear, like real building stuff. If I sent here my log could be helpful?

Judging from your logs it looks like all necessary files have been installed except the headers. I have no idea why, but on your system the C:\Qt\5.13.2\msvc2017_64\bin\qmake.exe -install qinstall ... commands that should copy the headers have been skipped.

The files in c:\Qt\5.15.1\msvc2019_64\include\QtQmqtt are: qmqtt.h qmqtt_client.h qmqtt_frame.h qmqtt_global.h qmqtt_message.h qmqtt_networkinterface.h qmqtt_routedmessage.h qmqtt_router.h qmqtt_routesubscription.h qmqtt_socketinterface.h qmqtt_timerinterface.h QtQmqtt QtQmqttDepends QtQmqttVersion qtqmqttversion.h

Inside this directory there's also a subdirectory 1.0.0\QtQmqtt\private, which contains the files: qmqtt_client_p.h qmqtt_message_p.h qmqtt_network_p.h qmqtt_socket_p.h qmqtt_ssl_socket_p.h qmqtt_timer_p.h qmqtt_websocket_p.h qmqtt_websocketiodevice_p.h

I match the logs and something missing I dont know why. So I tried to follow another path: i imported some headers directly in my project image Then I included the library that a friend told me to use inside my main.cpp but Im not sure they are sufficient image and then I tried to create inside my main.cpp a Client, subscribe to HIVE broker and publish a message

image No message received but all the stuff worked compiled on Android Studio. There is a wiki in order to use it correctly? Or can you guide me to an example of sending and listening (my main concern is publish some messages, actually I dont need to listen for them) Thank you again

ejvr commented 4 years ago

We have a small example project in the repo: https://github.com/emqx/qmqtt/tree/master/examples/qmqtt/client

I can't find anything wrong with your code except:

You can find all of this in the example project.

Trikos commented 4 years ago

Ok Im checking the example. About your last point I create at the begin this object QApplication app(argc, argv); and at the end of my main.cpp return app.exec(); Is this ok or I have to use QCoreApplication? I use QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling); at the first line of my main and then never again

Trikos commented 4 years ago

I tried the example but on compilation I get these errors:

I tried to comment out the whole code but these errors appear anyway. Inconsistent dll linkage

ejvr commented 4 years ago

Is this ok or I have to use QCoreApplication?

Yes, QApplication should work, because the class inherits QCoreApplication.

About the dll linkage errors: it seems you are compiling qmqtt itself, not the example. This should work, but apparently it does not on your system. You can work around it by opening example.pro in QT creator, which allows you to compile the example only.

Any news here or may we close this?

ejvr commented 4 years ago

I would close the issue. We can always reopen it. It seems to be a problem in a single system.

Hi @mwallnoefer

I have the same problem. I can compile running:

qmake
make
make install

but in the C:\Qt\6.2.3\mingw_64\include\QtQmqtt I find only the QtQmqttDepends file and my Qt project cannot find "qmqtt.h" header.

Also, running make all it fails in compiling the examples because It couldn't find the qmqtt.h file.

SO: Windows10 Qt: 6.2.3 qmake: 3.1 mingw32-make: 4.2.1

How can I solve the problem?

thanks

mwallnoefer commented 2 years ago

Please consider issue #221 (in detail ejvr's answer: https://github.com/emqx/qmqtt/issues/221#issuecomment-803454316). If it doesn't help let us continue the discussion there.

Gappa88 commented 2 years ago

thanks @mwallnoefer for the answer.

I copied all the header files that @ejvr pointed out here (just few comments above) and now I can compile, run, connect and push to a mosquitto broker successfully.

Now I have to repeat the procedure on another computer...

Is there something that I can change in the Cmakefile or somewhere else in order to make it work properly?

thanks again

mwallnoefer commented 2 years ago

I guess if @ejvr does not answer we cannot do much about it. Please consider qmqtt as semi-abandonware: it isn't developed any further, we just accept bug-fixes but no new features.

ejvr commented 2 years ago

I don't have a lot info to add here. Normally, I would check the output of the make install to find out if qmqtt.h was copied and to which location.
