On Fedora, you need to first:
sudo dnf install gcc make automake autoconf texinfo patch libwebsockets libwebsockets-devel json-c json-c-devel openssl-devel file-devel libcap-devel asciidoctor

sudo dnf install gcc-c++ qt5-qtbase-devel qt5-qtwebengine-devel qt5-qtwebchannel-devel

sudo dnf install vim-common
For Java classes, do:
sudo dnf install java-1.8.0-openjdk-devel
(You can also use Oracle JDK, version 8 or 9.)
(Tested on Ubuntu 17.10.1)
You need to install the following prerequisites:
sudo apt-get install git gcc make automake libjson-c-dev pkg-config asciidoctor libmagic-dev zlib1g-dev
--with-qtwebengine (recommended), also do:
sudo apt-get install qt5-qmake qt5-default libqt5webengine5 libqt5webchannel5-dev qtwebengine5-dev
In the future you should be able to do
apt-get install libwebsockets-dev, but at the time of writing the available package is too old,
so you have to build libwebsockets from source - see below.
If you need to build libwebsockets from source:
sudo apt-get install cmake
For building from source on WSL (Windows Subsystem for Linux) see the instructions below.
Alternatively, you can use of the pre-compiled
Then create a directory on a Windows partition,
cd to it,
unzip the downloaded file into the partition.
For example (assuming your Windows user name is
wusermkdir DomTerm cd DomTerm unzip /mnt/c/User/wuser/Downloads/domterm-
These library dependencies are needed:
apt-get install libjson-c2 libmagic1 zlib1g
Optionally you can create a symlink for
cd ~/bin ln -s /mnt/c/
Installing Electron is highly recommended.
brew install automake brew install json-c brew install libwebsockets brew install asciidoctor
There are some issues about openssl that I’m not clear about. A reported work-around is to do:
export LDFLAGS="-L/usr/local/opt/openssl/lib -L/usr/local/lib -L/usr/local/opt/expat/lib" export CFLAGS="-I/usr/local/opt/openssl/include/ -I/usr/local/include -I/usr/local/opt/expat/include" export CPPFLAGS="-I/usr/local/opt/openssl/include/ -I/usr/local/include -I/usr/local/opt/expat/include"
A cleaner solution/fix would be welcome.
domterm server requires libwebsockets version 2.2
or newer. As of January 2018, the version in Fedora 27 in fine,
but the version in Ubuntu is too old.
If you need to build libwebsockets from source, do the following:
cd $WORKDIR git clone https://github.com/warmcat/libwebsockets cd libwebsockets mkdir build cd build cmake -DLWS_WITH_SSL=0 -DLWS_WITH_ZIP_FOPS=1 ..
-D optional are suggested but not required:
-DLWS_WITH_SSL=0 avoids a dependency on OpenSSL;
-DLWS_WITH_ZIP_FOPS=1 is required if configuring

Microsoft Windows is now supported using Windows Subsystem for Linux (WSL). This has been tested using the Ubuntu distrubution: Follow the above Ubuntu instructions for getting prerequsities (without the optional qt packages), including (currently) building libwebsockets from source.
