The wiki is currently not user-editable, which rather defeats the purpose of a wiki and, in any case, is certainly against the spirit of a wiki.

Consider opening the wiki to anonymous edits. Also consider migrating to Github, whose UI and workflow is somewhat less cluttered than that of SourceForge. Until then, I'll just leave this here.

Compilation

Largely thanks to an Autotools-based makefile, it is feasible but highly non-trivial to compile Netgen on your own. This is complicated by the need to explicitly specify the absolute paths of dependency directories, as detailed below.

Ubuntu

As of this writing (mid-2015), the version of Netgen officially provided by Ubuntu is painfully out of date (4.9.13). Since there sadly exists no PPA unofficially providing a more recent versions, Ubuntu users are encouraged to manually compile Netgen. In order:

Install METIS, OpenMPI, and Togl, including development headers for the latter two.
sudo apt-get install metis openmpi-bin libopenmpi-dev libtogl-dev
Download the newest stable release of Netgen.
Open a terminal window.
Change to the directory containing the downloaded tarball: e.g.,
cd ~/Downloads
Extract that tarball into the current directory.
tar -xvzf netgen-*.tar.gz
Remave that tarball.
rm netgen-*.tar.gz
Change to the newly extracted directory.
cd netgen-*
Temporarily add the OpenMPI include directory to the ${CPPFLAGS} variable.
CPPFLAGS="-I/usr/lib/openmpi/include/"
export CPPFLAGS
Configure Netgen, enabling installation of the nglib.so shared library to support Elmer and other high-level FEM frameworks. (You want this.)
./configure --with-sysroot=/usr/lib/ --with-tcl=/usr/lib/tcl8.5/ --with-tk=/usr/lib/tk8.5/ --with-togl=/usr/lib/ --with-metis=/usr/lib/x86_64-linux-gnu/ --enable-nglib
Compile Netgen.
make
Install Netgen.
sudo make install
Add the following lines to your user-specific ~/.profile shell startup script.
LD_LIBRARY_PATH=/opt/netgen/lib
NETGENDIR=/opt/netgen/bin
PATH="${PATH}:${NETGENDIR}"
export LD_LIBRARY_PATH
export NETGENDIR
export PATH
If ~/.profile does not already exist, create such file and ensure that your preferred shell sources such file. For example, under zsh, add the following line to your user-specific ~/.zshrc shell script:
source "${HOME}/.profile"
Source the newly modified ~/.profile.
source ~/.profile
Run Netgen.
netgen &!

Ignored `configure` Options

Attempting to enable the --enable-jpeglib option induces the following error from ./configure and has thus been omitted above:

OCCFLAGS = -DOCCGEOMETRY -I/usr/share/oce-0.15/inc -I/usr/include/opencascade -D_OCC64 -DHAVE_IOSTREAM -DHAVE_LIMITS -DHAVE_LIMITS_H -DHAVE_IOMANIP

Likewise, attempting to enable the --enable-occ option induces the following error from make and has thus been omitted above:

Likewise, attempting to enable the --enable-ffmpeg option induces the following error from make and has thus been omitted above:

The latter error is probably correctable by installing all libav development headers (e.g., libavcodec-dev).
