QT5: Where are the multimedia libraries?

Hi,

I am using / trying to use QT just for a few days now. I have build QT5 from the source (for the zip file ... not from Git) as described here: http://qt-project.org/wiki/MinGW-64-bit

Building OpenSSL, ICU, Qt5 and Webkit works fine. My first Hello-World-app works fine, too.

But now I want to go a little bit in the deep and wanted to play an MP3 file. I found some examples in the qtmultimedia folder of Qt, but when I try to compile them, I get an error message: Qt Multimedia not found.

I have already tried "mingw32-make module-qtmultimedia" (as I found it on an other web page), but it still doesn't work.

Does someone have any Ideas?

Regards,

Rainer

It's likely you are missing some dependencies required to build that module. Check the output of configure to get a list of modules that are going to be built.

The funny thing is: at work (with Windows 7 Pro 32bit)I just needed to install the DirectX SDK, too. After that I the QT5Multimedia.dll (and some otheres DLLs files) were created.

At home (Windows 7 64bit ultimate) I installed the DirectX SDK, too. I added the "-audio-backend" flag to the configure command, but I am still missing some DLLs.

Here ist my configure command:

Code:

---

configure -debug-and-release -opensource -confirm-license -platform win32-g++ -developer-build -c++11 -icu -opengl desktop -openssl -plugin-sql-odbc -qt-style-windowsxp -qt-style-windowsvista -audio-backend -nomake tests

The output of this command is the following:

Can you see any reason why it doesn't work?

Please read the whole output of configure and find the part responsible for checking multimedia support.
