Installing Qucs on Ubuntu

Qucs is a free circuit simulator for Windows, Linux and Mac. It comes complete with a schematic editor, project manager and other useful tools.
Qucs is very easy to use and support the standard DC, AC, Parameter Sweep, Transient, digital and other simulations, it also includes a selection of popular component models.
Qucs can display the simulation data in a number of ways such as Cartesian Plot, Polar, Tabular, Smith Chart, Timing Diagram and Truth Table.

Installing

First open the terminal and type the following:

cd ~
wget -t5 http://downloads.sourceforge.net/project/qucs/qucs/0.0.15/qucs-0.0.15.tar.gz?use_mirror=kent

This is download the latest version of Qucs, once that is done you will need to extract it:

tar -xvzf qucs-0.0.15.tar.gz

If you want to delete the Qucs source archive you can do so by using this, if not skip this next command.

rm qucs-0.0.15.tar.gz

Now you need to move the folder to where you want to compile it, if you don’t mind it being in your home folder skip this:

sudo mv qucs-0.0.15 /usr/src
cd /usr/src/qucs-0.0.15

Next move into the folder and download the dependencies required to compile Qucs:

cd qucs-0.0.15
sudo apt-get install libqt3-headers

Finally you can compile Qucs:

./configure
make
sudo make install

Once this is done (hopefully without any errors) you can run Qucs simply by typing:

qucs

That’s all, although I’d suggest adding a shortcut to your menu.

Installing EDuke32

Install requirements

GNU C++ Compiler (g++)
libSDL runtime & development files
NASM (Assembler)
GTK+ 2.0 runtime & development files
libVorbis development files
—
Subversion (SVN) – to download the latest EDuke32 source
Timidity – software MIDI player

First check you have the build tools installed by running

gcc –version

You should be given the version, if you get something like ‘command not found’ you will need to install the build tools.
If the version is below 4.0 you should upgrade your build tools to version 4.3 or greater.

If you using Ubuntu you can use the following command to install the build tools.

sudo apt-get install build-essential

If you not using Ubuntu you should search your distributions package manager for the build tools.

All the required development files can be installed on Ubuntu using the following, again check your package manager if you are using a different distribution.

sudo apt-get install subversion timidity libsdl1.2-dev libsdl-image1.2-dev libsdl-mixer1.2-dev nasm libgtk2.0-dev libvorbis-dev

Getting EDuke32

Now you need to get the latest version of EDuke32.

cd ~
svn co https://eduke32.svn.sourceforge.net/svnroot/eduke32 eduke32

I assume your going to build in your home directory, if not I suggest you use /usr/src

Building EDuke32

Once EDuke32 is downloaded you can build it.

cd eduke32/polymer/eduke32
make

If the build completes without errors you should find two executables in your current directory.
Next you need to make the directory where you will place EDuke32 and Duke Nukem 3D.

mkdir ~/duke3d
mv eduke32 ~/duke3d
mv mapster32 ~/duke3d
cd ~/duke3d

Using EDuke32

Alternatively you may install EDuke32 globally, (I.E in /usr/bin) for information on doing this read the EDuke32 wiki.
Now simply get your version of Duke Nukem 3D and look for the file called DUKE3D.GRP. Move this file to where the EDuke32 executable is located. (I.E ~/duke3d)
Once that is done simply run EDuke32 with:

./eduke32

Important Note: ensure that the DUKE3D.GRP file is LOWER CASE, such as duke3d.grp or EDuke32 will not be able to read it, hopefully this will be fixed in future.
I will show you how to use multiplayer in my next post.

Update
There are APT repositories for Debian and Ubuntu for easy installation.
