项目错误:QT中的未知模块:多媒体 [英] Project ERROR: Unknown module(s) in QT: multimedia

问题描述

在安装qt5

git clone https://github.com/pzorin/qgo.git
cd qgo
qmake
make
sudo make install

现在最新的错误是说它找不到多媒体

Right now the latest error is saying it can't find multimedia

# make
cd src/ && ( test -e Makefile || /usr/lib/x86_64-linux-gnu/qt5/bin/qmake /home/jdm/Downloads/qgo/src/src.pro -o Makefile ) && make -f Makefile 
Project ERROR: Unknown module(s) in QT: multimedia
make: *** [sub-src-make_first] Error 3

我根据这个问题猜出了库libqt5multimedia5，但是它说它已经在那儿的计算机上了，错误仍然存​​在.

I guessed the library libqt5multimedia5 based on this question, but the computer it says its already there and the error persists.

libqt5multimedia5 is already the newest version.

I'm not able to post a comment, so I will write it as an answer. Your problem has been solved here: https://forum.qt.io/topic/27608/unknown-module-multimedia/6

为了处理该问题，您应该尝试安装不存在的软件包:

In order to handle the issue you should try installing packages that are absent:

sudo apt-get install qtmultimedia5-dev libqt5multimediawidgets5 libqt5multimedia5-plugins libqt5multimedia5

，然后重新启动Qt Creator. 干杯.

and restart your Qt Creator after that. Cheers.

更新.如果它不起作用，请尝试其他解决方案:

UPDATE. If it will not work, try another solution:

sudo apt-get update
sudo apt-get build-dep qtmultimedia5-dev
sudo apt-get source --compile qtmultimedia5-dev

更新2 对我来说，解决方法如下:

UPDATE 2 For me the solution was the following:

1. 从 http://download下载源.qt.io/development_releases/qt/5.4/5.4.0-rc/submodules/

构建它们，手动添加库.

Build them, add the library manually.
