How to connect Risip in Qt

Maybe it's the debugger

Actually, none of the errors you listed are caused by the debugger.

error of Qt-Asterisk-Desktop-master: dependent 'phonon\seekslider.h' does not exist.

This error tells you that the project is looking for a header file called seekslider.h, but it cannot find the header.

error qt-asterisk-code-r100 : Unknown module(s) in QT: webkit

This error tells you that Qt WebKit is not installed.

The Qt WebKit module was deprecated and removed from Qt 5.6.

You have 2 options:

Downgrade to Qt 5.5, OR
Install an unofficial version: https://github.com/annulen/webkit/tree/qtwebkit-5.212.0-alpha2

errors of metasec: C:\Users\New Owner\Downloads\MetaVoIP1\pjproject-2.4\pjlib\include\pj\config.h:278: error: C1189: #error: "Please specify target machine."

config.h requires you to #define a macro so that #ifdef logic will not lead to an #error.

Read config.h, especially the lines above line #278 to figure out what you need to do.

error js AsteriskManager-master:: No rule to make target 'C:/Users/New Owner/Downloads/AsteriskManager-master/build-test-Desktop_Qt_5_12_3_MinGW_64_bit-Debug/../src/debug/libasteriskmanager.a', needed by 'debug/tst_loginactiontest.exe'. Stop.

I'm not sure about this error. Fix the others first, then come back to this one.

It looks like each of these projects will be a lot of fuss. Maybe you know how to connect PJSIP?

I've never used PJSIP before, sorry.

I can offer help with things related to Qt, but I can't offer help with external tools that I've never used before.

If this is important to you, I recommend you hire a professional to help you.

How do you connect such libraries with the help of the compiler?

@Mikeeeeee said in How to connect Risip in Qt:

Download (or build) a version of the library that is compatible with your compiler.
Add the library to your project: https://doc.qt.io/qt-5/qmake-project-files.html#declaring-other-libraries
#include the library headers in your own code and call the library functions
Build your code

But PJSIP does not have dll and lib files.

mrjj

Hi
You are supposed to produce the DLL and lib files your self by closely following
https://trac.pjsip.org/repos/wiki/Getting-Started/Windows

@mrjj is right. As I said in my previous post:

build a version of the library that is compatible with your compiler.

Here, "build" means use your compiler to create .dll/.lib files from the library's source code.

There is described an option for Visual Studio. But how to do it in Qt?

jsulm

@Mikeeeeee Since you're using MSVC++ compiler (from Visual Studio) build the lib using the description for Visual Studio.

Mikeeeeee

But is it possible to compile this dll into Qt? I have MSVC2019, but I never used it. How can I build a Dll in MSVC2019 (I created a library project)?

You don't compile a dll "into Qt". You simply compile it and then use in your app.

It is important to understand:

C++ is a language.
PJSIP is a C++ library.
Qt is a C++ library (mostly).
Qt Creator is an IDE.
Visual Studio is an IDE.
Microsoft Visual C++ is a compiler.

You use an IDE to write code and build applications/libraries. You need to tell your IDE which compiler to use.

You can use Visual Studio to write C++ applications that link to the Qt and PJSIP libraries.
You can use Qt Creator to write C++ applications that link to the Qt and PJSIP libraries.

How can I build a Dll in MSVC2019 (I created a library project)?

You must follow the instructions from PJSIP documentation. We do not know how to build PJSIP.
