没有指定目标，也没有找到makefile。 停
我有问题你去，我想安装qtractor。 我在终端写道
cd /home/hl/Documenten/qtractor-0.6.0 之后我写了并输入：
sh ./configure
这就是我得到的。

在此之后我写下并输入make
no targets specified and no makefile found. stop
是依赖性问题：您没有安装qt4库。
安装所有依赖项：
sudo apt-get install libqt4-dev sudo apt-get install libjack0 sudo apt-get install libjack-dev sudo apt-get install libasound2-dev sudo apt-get install libsndfile1-dev
现在，运行：
./configure
之后，键入：
make
最后：
sudo make install
