Dependencies

Conan inclusion

This project depends on conan (v1.5 and higher, v2.0 not supported) to build it's dependencies. See https://conan.io/ to install conan.

Other dependencies

• C++20
• cmake - at least 3.20

Build and run

1. Create a build directory. For example: build
2. Change to that directory.
3. Configure conan (once before very 1st build)

conan profile update settings.cppstd=20 default
conan profile update settings.compiler.libcxx=libstdc++11 default
conan profile update settings.arch=x86_64 default

4. Run conan. The command is:

conan install -b missing -s build_type=Debug --output-folder . ..

(Note: the exact command I use is as follows, but this assumes gcc 12 is used and a gcc12 conan profile is present):

CC=$(which gcc) CXX=$(which g++) conan install -b missing --profile gcc12 -s build_type=Debug --output-folder . ..

5. Create a build file (replace .. with the appropriate directory):

• 5.1) Default. If you don't have installed rippled - this setup will download and build it.

cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=build/generators/conan_toolchain.cmake ..

• 5.2) If you have rippled build from source you can use it

cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=build/generators/conan_toolchain.cmake -DRIPPLE_SRC_DIR=/home/user/repo/rippled -DRIPPLE_BIN_DIR=/home/user/repo/rippled/build-release ..

6. Build the project:

make -j $(nproc)

7. Run

./xbridge_witnessd --conf /home/user/repo/config.json
