    Hi,

    If you want to build with MinGW I would recommend using the version that matches the one used for Qt.

        Hello all

        I downloaded vlc-qt (vlc-qt.tano.si) and i try to run a exemple (from here https://github.com/vlc-qt/examples). I downloaded the stable version for windows and i specified the path to those library in my src.pro. When i compile i gets some error that i dont understand. Note that it works fine on linux, I work with Qt editor.

        C:\Users\Paul\Desktop\examples-master\build-simple-player-Desktop_Qt_6_2_0_MinGW_64_bit-Debug\src/../../simple-player/src/SimplePlayer.cpp:27: undefined reference to __imp__ZN11VlcInstanceC1ERK5QListI7QStringEP7QObject'

        here is my .pro fil : https://pastebin.com/5z6iwT1P

        I'm out of idea. Please someone help me.

        Thanks

        @polohpi According to what you reviewed vlc-qt only provides the 32-bit binaries for mingw but you are using mingw for 64-bit.

        If you want me to help you develop some work then you can write to my email: e.yllanescucho@gmal.com.

          Please try with MinGW provided by Qt installer to make sure you're using exactly same compiler as you use for Qt.

            @eyllanesc indeed there is a 32 bit version for mingw and 64 bit version for MSVC. I didnt know what to choose. So if i try with MSVC how can i do it ?

                I have changed the compiler in qt editor to the msvc2015. I have a new error : "rc.exe" impossible to execute. Note that rc.exe is only in C:\Program Files (x86)\Windows Kits\10\bin

                UPDATE :

                After pointing to a specific folder where rc.exe is, i add the dll to my release folder and tryed to launch my exe. Nothing happened. Even when i try to run it via qt editor it seems to crash. I dont know how to solve the issue.

                  Did you also install Qt for that compiler?
                  You can't mix binaries created using incompatible compilers.

                      There is no need to modify anything, just install Qt for msvc2015.
