How to install


There are no precompiled Linux packages (*.deb and *.rpm) and you need to compiled it from source. Refer to README.md to install all necessary dependencies. You need C++ compiler, build tools, and Qt4. You need also to install ngspice and/or XYCE. Ngspice is shipped by the most of Linux distributions. For example:

apt-get-install ngspice

will install Ngspice for Debian-like.

If have no previos Qucs versions installed you can unpack and compile as usual:

tar xvfz qucs-0.0.19S-rc5.tar.gz
cd qucs-0.0.19S-rc5
cd qucs
make install
cd qucs-core 
make install

If you already have other Qucs versions installed you may want to have two installations side-by-side. You need to use --prefix for GUI an core respectively switch in such case. You can set any desired directory (for example /opt) for Qucs-S package installation here:

./configure --prefix=/some_qucs_location/

If you are interested only in SPICE simulations, you need to build only Qucs-GUI. You can also use side-by-side installation of multiple versions with --prefix . Qucs will be installed in default /usr/local/ location, if this option is omitted:

tar xvfz qucs-0.0.19S-rc5.tar.gz
cd qucs-0.0.19S-rc5/qucs
./configure --prefix=/some-qucs-location/
make install


You need to use binary installer for Windows. You need to download and install Ngspice and/or XYCE manually from official websites: http://ngspice.org/ https://xyce.sandia.gov/ respectively
