Build JMES Core

JMES Core is the official Golang reference implementation of the JMES node software. Use this guide to install JMES Core and jmesd, the command-line interface and daemon that connects to JMES and enables you to interact with the JMES blockchain.

Get the JMES Core source code

1. Use git to retrieve JMES Core, and check out the feat/winning_grants branch, which contains the latest stable release. You can find the latest tag on the tags page or via autocomplete in your terminal: type git checkout v and press <TAB>.

   
   

   _1

   git clone -b feat/winning_grants https://github.com/jmesworld/core

   
   

2. Use git to retrieve the jmesworld version of Cosmos SDK, and check out the v0.0.99-alpha.3 tag, which contains the latest stable release. Also, find the path to this folder for use in step 4.

   
   

   _1

   git clone https://github.com/jmesworld/cosmos-sdk.git

   
   
   
   

   _2

   # Switch to your cosmos-sdk folder

   _2

   cd cosmos-sdk

   
   
   
   

   _2

   # Checkout the latest tagged version to a local branch

   _2

   git checkout tags/v0.0.99-alpha.3 -b latest

   
   
   
   

   _3

   # Note the path to the folder and return to the home directory

   _3

   pwd # e.g. /root/cosmos-sdk

   _3

   cd ..

   
   

3. Similarly, use git to retrieve the jmesworld version of Tendermint, and check out the v0.99.0-alpha.1 tag, which contains the latest stable release. Also, find the path to this folder for use in step 4.

   
   

   _1

   git clone https://github.com/jmesworld/tendermint.git

   
   
   
   

   _2

   # Switch to your tendermint folder

   _2

   cd tendermint

   
   
   
   

   _2

   # Checkout the latest tagged version to a local branch

   _2

   git checkout tags/v0.99.0-alpha.3 -b latest

   
   
   
   

   _3

   # Note the path to the folder and return to the home directory

   _3

   pwd # e.g. /root/tendermint

   _3

   cd ..

   
   

4. Replace cosmos-sdk and tendermint dependencies in the replace section of the go.mod file. Ensure you replace <PATH TO YOUR local folder> with those nnoted in Steps 2 & 3 above.

   
   

   _5

   cd core

   _5

   _5

   sed -i 's|github.com/cosmos/cosmos-sdk => github.com/jmesworld/cosmos-sdk v0.46.0-jmes.1| github.com/cosmos/cosmos-sdk => <PATH TO YOUR cosmos-sdk folder>|g' go.mod

   _5

   _5

   #Example: sed -i 's|github.com/cosmos/cosmos-sdk => github.com/jmesworld/cosmos-sdk v0.46.0-jmes.1|github.com/cosmos/cosmos-sdk => /root/cosmos-sdk|g' go.mod

   
   
   
   

   _3

   sed -i 's|github.com/tendermint/tendermint => github.com/jmesworld/tendermint v0.34.21-jmes.1| github.com/tendermint/tendermint => <PATH TO YOUR tendermint folder>|g' go.mod

   _3

   _3

   #sed -i 's|github.com/tendermint/tendermint => github.com/jmesworld/tendermint v0.34.21-jmes.1| github.com/tendermint/tendermint => /root/tendermint|g' go.mod

   
   

5. Build JMES Core. This will install the JMESd executable to your GOPATH environment variable.

   
   

   _1

   make install

   
   

6. Verify that JMES Core is installed correctly.

   
   

   _1

   jmesd version --long

   
   

   Example:

   
   

   _7

   name: jmes

   _7

   server_name: jmesd

   _7

   version: feat/winning_grants-8d8a9c26047d9b834ada5c3c7c6880857b3ee4e1

   _7

   commit: 8d8a9c26047d9b834ada5c3c7c6880857b3ee4e1

   _7

   build_tags: netgo ledger,

   _7

   go: go version go1.20.4 linux/amd64

   _7

   # ...followed by a lot of dependenecies

   
   

💡tip

If the jmesd: command not found error message is returned, confirm that the Go binary path is correctly configured by running the following command:

_1

export PATH=$PATH:$(go env GOPATH)/bin
