DrawPile is a drawing program with a twist: you can share your drawing live with other people.

Some feature highlights:

• Shared canvas using the built-in server or a dedicated server
• Record, play back and export drawing sessions
• Layers and blending modes
• Text layers
• Supports pressure sensitive Wacom tablets
• Built-in chat
• Supports OpenRaster file format

Dependencies:

• Qt 5.0 or newer
• zlib

For building just the dedicated server, only QtCore and QtNetwork are required.

It's a good idea to build in a separate directory to keep build files separate from the source tree.

Example:

$ mkdir build
$ cd build
$ cmake ..
$ make

The executables will be generated in the build/bin directory. You can run them from there, or install them with make install.

The configuration step supports some options:

• CLIENT=off: don't build the client (useful when building the stand-alone server only)
• SERVER=off: don't build the stand-alone server.
• DEBUG=on: enable debugging features

Example: $ cmake .. -DDEBUG=on
