Note: You might not need to build a copy of the library for Linux - precompiled deb files for 64 bit and 32 bit Debian and Ubuntu are provided in the GitHub version releases. Unless you are on a different Linux distribution which does not support the installation of deb files, or wish to submit fixes and enhancements to the library itself you should have an easier time installing the precompiled version instead.

1. Build Source Code

cmake -B ./build

cmake --build ./build -j8

Replace the number after -j with a number suitable for your setup, usually the same as the number of cores on your machine. cmake will fetch any dependencies that are required for you and ensure they are compiled alongside the library.

2. Install to /usr/local/include and /usr/local/lib

cd build

sudo make install

3. Installation to a Different Directory

If you want to install the library, its dependencies, and header files to a different directory, specify this directory when running cmake:

cmake .. -DCMAKE_INSTALL_PREFIX=/path/to/install

Then once the build is complete, run make install to install to the location you specified.

4. Using the Library

Once installed to the /usr/local directory, you can make use of the library in standalone programs simply by including it and linking to it:

g++ -std=c++17 mydppbot.cpp -o dppbot -ldpp

The important flags in this command-line are:

-std=c++17 - Required to compile the headers
-ldpp - Link to libdpp.so
mydppbot.cpp - Your source code
dppbot - The name of the executable to make

Note: Compiling your bot with a raw `g++` command is not advised in any real project, and the example above should be used only as a test. From here, you should learn to create a bot in D++ by moving on to Building a Discord Bot Using CMake (UNIX) or if you have not yet created a token for your bot, Creating a Bot Token - If you are having trouble setting up CMake, you can try our template cmake bot project.

Have fun!
