    @polohpi said in vlc-qt giving error when compiling:

    I try to compile vlc-qt by myself on windows but i cant make cmake to work even by following what vlc-qt advise

    So, you actually do not have vlc-qt libs because you cannot compile it? Then of course you will not be able to compile any project using vlc-qt. You first need to build vlc-qt. You can post your problems building vlc-qt here. Maybe we can help to solve those.

      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.

                    You can't mix binaries created using incompatible compilers.

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