Install using rustup.rs:
curl https://sh.rustup.rs -sSf | sh; source $HOME/.cargo/env
If rust is already installed, you should update to the latest version by running
Grin currently does not support a minimum version of Rust, so it's recommended to build using the latest version.
git ● tor ● clang ● ncurses and libs (ncurses, ncursesw5) ● zlib libs (zlib1g-dev or zlib-devel) ● pkg-config ● libssl-dev ● llvm ● linux-headers (needed on Alpine linux)
For Debian-based distributions (Ubuntu, Mint etc):
apt install build-essential git tor cmake git libgit2-dev clang libncurses5-dev libncursesw5-dev zlib1g-dev pkg-config libssl-dev llvm
xcode-select --install brew install --with-toolchain llvm brew install pkg-config brew install openssl
git clone https://github.com/mimblewimble/grin.git cd grin git checkout v4.0.2 cargo build --release
Grin can also be built in debug mode (using the
--debug or the
--verbose flags) but this will render fast sync prohibitively slow due to the large overhead of cryptographic operations.
Build errors ↴
Build error: Could not compile
You might want to remove any previous rust installations to avoid conflicts. Use
rustup to reinstall rust and cargo as described.
NOTE: If you install rust or cargo with your package manager (most Linuxes anno 2017) you’ll get too old versions. On Debian, you might have to manually compile cmake or get it from non-detault repositories.
failed to select a version for ‘serde_json’
cargo update to fix this
Build error: can’t compile crate
rustc –version and note that bitflags requires rust 1.21 or newer. Install via
rustup and recommended you also remove any rust/cargo installed via your package manager.
Build error: can’t locate stdarg.h
If librocksdb-sys fails to build, try symlinking stddef.h and stdarg.h from the gcc5 include directory. So probably from /usr/lib to /usr/include
/usr/bin/ld: cannot find -lz
On Ubuntu install the zlib development headers:
apt install zlib1g-dev.
/usr/bin/ld: cannot find -lncursesw
On Ubuntu install the ncurses development headers:
apt install libncursesw5-dev.
What was built?
Let's review what a successful build gets you.
target/release/grin is your main grin binary, located inside the build directory.
To add it to your path, type:
You can then run
grin from anywhere on your system.
All data, configuration and log files created and used by grin are located by default in the hidden
~/.grin directory (under your user home directory).
You can modify configuration values by editing the
grin-server.toml file, located in
You can have grin create its data files in the current directory. To do this, run:
grin server config
This will generate a
grin-server.toml file in the current directory. Running grin from a directory that contains
grin-server.toml will use the values in that file which will also be pre-configured to use the current directory for all of the node's data.
Grin attempts to run with sensible defaults, and can be further configured via
grin-server.toml file, generated by grin on its first run. The file contains documentation on each available option.
While it is recommended that you perform all grin server configuration via
grin-server.toml, it's also possible to supply command line switches to grin that override any settings in the file.
For help on grin commands and their switches, try:
grin help grin server help grin client help
Once your grin node is up and running, you can start mining by building and running grin-miner against your node.
For grin-miner to be able to communicate with your grin node, make sure that you have
enable_stratum_server = true in your
grin-server.toml configuration file and you have a wallet listener running (
(Running grin in a container)
docker build -t grin -f etc/Dockerfile .
For floonet, use
You can bind-mount your grin cache to run inside the container.
docker run -it -d -v $HOME/.grin:/root/.grin grin
If you prefer to use a docker named volume, you can pass
-v dotgrin:/root/.grin instead. Using a named volume copies default configurations upon volume creation.
