Reinstall Qt5 with QtMultimedia using Ubuntu Mate

SGaist

Don't build the tests nor the example, especially since your are cross-compiling. There's no use for that and you'll waste space, time and electricity for nothing.

Xenoshell

@SGaist So are the errors now important or can i just install without worries?
@JonB I just wanna cross out all possibilities what could be wrong

jsulm

@Xenoshell As you can see from what you posted those errors are coming from examples. As @SGaist suggested there is no need to build examples and tests (so, no these errors are not important). Use -skip to not to build examples and tests.

Xenoshell

@jsulm yeah, since make is now finished its a little bit too late to skip the examples. But its good to know that those errors dont matter

Xenoshell

@jsulm , @JonB somehow in the qt5 folder there is no qtmultimedia. I think i am going mental

jsulm

@Xenoshell make install ?

Xenoshell

@jsulm yeah already did that

jsulm

@Xenoshell Do you mean there is no libQt5Multimedia.* in lib directory and no header files?

Xenoshell

@jsulm nope in the lib folder there is only just everything else. Here is my command i used ./configure -opengl desktop -gui -widgets -gstreamer -pulseaudio -alsa -ffmpeg -dbus-linked, Do i maybe have to also add -multimedia?? I dont think there even is that command, but what do i have to do to install QtMultimedia

SGaist

Are you calling configure from the top folder ?
If so, did you clean everything before calling configure again ?

As I suggest every time: use out of source builds, that way if something goes wrong or you want to use a different set of option, you can simply nuke everything or change the folder and you know for sure you start from a clean state.

Xenoshell

@SGaist i called configure from the top folder i got from the .tar.gz file. I just deleted config.cache before calling configure again. How would i go about cleaning everything before calling configure again? What are out of source builds?

SGaist

make distclean or make confclean

As the name suggests: builds that happens out of the source tree.

Basically:

mkdir /home/your_user/build_qt5
pushd /home/your_user/build_qt5
/path/to/Qt_sources/configure -nomake tests -nomake examples
make -j (number_of_cores * 2 + 1)
make install
popd

Xenoshell

@SGaist Ok, is this even useful now? I mean i already installed Qt5 so isnt it a little bit too late?
Btw in my other post about my code are some new outputs since i installed Qt5.

SGaist

It will be in the future when you'll build Qt again.
