系统:Kubuntu-64-bit 20.04 - AMD 64-bit machine
我试图从源代码安装相当通用的电路模拟器并得到错误:
configure: error: Qt >= 4.6.0 is required.
configure: error: ./configure failed for qucs
尝试安装 Qt-4 得到错误:
apt-get install qt4-dev-tools libqt4-dev libqt4-core libqt4-gui
E: Unable to locate package qt4-dev-tools
E: Package 'libqt4-dev' has no installation candidate
E: Unable to locate package libqt4-core
E: Unable to locate package libqt4-gui
我如何得到这份工作?
