/bin/sh: g++: not found
make[1]: *** [scripts/kconfig/qconf.o] Error 127

make: *** [xconfig] Error 2

原因：

没安装qt/x11

make xconfig 基于KDE的桌面系统……

首先安装gcc g++
sudo apt-get install build-essential

然后装libqt3-mt试试
sudo apt-get install libqt3-mt

如果还是报No package 'qt-mt' found 继续装libqt3-mt-dev
sudo apt-get install libqt3-mt-dev
