Build Redropp

The Redropp server is Linux-only for the moment, and uses the Landlock LSM (and seccomp) which requires Linux 5.13 or more recent.

Redropp relies on C++ (server-side) and HTML/CSS/JS (client-side). Compiling Redropp uses a dedicated tool included directly in the repository.

Start by fetching the code from the Git repository: https://codeberg.org/Koromix/rygel

git clone https://codeberg.org/Koromix/rygel
cd rygel

To compile a development and test version, proceed as follows from the root of the repository:

# Prepare the felix tool used to compile Redropp
./bootstrap.sh

# The executable will be placed in the bin/Debug folder
./felix

For production use, it is recommended to compile Redropp in Paranoid mode using Clang 18+ and the LLD 18+ linker. On Debian 12, you can do the following:

# Prepare the felix tool used to compile Redropp
./bootstrap.sh

# Installation of LLVM described here and copied below: https://apt.llvm.org/
sudo bash -c "$(wget -O - https://apt.llvm.org/llvm.sh)"
sudo apt install clang-18 lld-18

# The executable will be placed in the bin/Paranoid folder
./felix -pParanoid --host=,clang-18,lld-18

Run Redropp

Once the Redropp executable is compiled, you can create a Redropp config using the following command:

# For this example, we will create this config in a tmp subfolder of the repository.
# But you can create it wherever you wish!

mkdir -p tmp
bin/Debug/redropp init tmp/test

To access this instance via a web browser, you can start it using the following command:

# With this command, Redropp will be accessible via http://localhost:8894/
bin/Debug/redropp -C tmp/test
