Can NOT build with mainnetExplorer mode

[congle-ibl]

Hi everyone,

I am using this command to build the project with "mainnetExplorer" mode: nix-build -A connectScripts.mainnetExplorer -o explorer_mainnet.sh

But I met the below issue. Could you please help take a look and suggest me what to do now? Thank you so much. src/Pos/Explorer/Txp/Local.hs:83:5: error: • Couldn't match type ‘Maybe ()’ with ‘()’ Expected type: m () Actual type: m (Maybe ()) • In a stmt of a 'do' block: txNormalizeAbstract buildExplorerExtraLookup (normalizeToil' extras) In the expression: do { extras <- MM.insertionsMap . view eemLocalTxsExtra <$> withTxpLocalData getTxpExtra; txNormalizeAbstract buildExplorerExtraLookup (normalizeToil' extras) } In an equation for ‘eTxNormalize’: eTxNormalize = do { extras <- MM.insertionsMap . view eemLocalTxsExtra <$> withTxpLocalData getTxpExtra; txNormalizeAbstract buildExplorerExtraLookup (normalizeToil' extras) } where normalizeToil' :: HashMap TxId TxExtra -> BlockVersionData -> EpochIndex -> HashMap TxId TxAux -> ELocalToilM () normalizeToil' extras bvd epoch txs = let ... in eNormalizeToil bvd epoch toNormalize [30 of 30] Compiling Pos.Arbitrary.Explorer ( src/Pos/Arbitrary/Explorer.hs, dist/build/Pos/Arbitrary/Explorer.o ) builder for '/nix/store/fl1apaayh1spd3677w91l84mk1ns0b10-cardano-sl-explorer-1.1.1.drv' failed with exit code 1 cannot build derivation '/nix/store/7yn62yv5w6f9llb81y7p5rb15hfd66kl-explorer-connect-to-mainnet.drv': 1 dependencies couldn't be built error: build of '/nix/store/7yn62yv5w6f9llb81y7p5rb15hfd66kl-explorer-connect-to-mainnet.drv' failed

Hi @congle-ibl !

For building and starting the project on mainnet the following commands can be used (they start the importer, not the explorer):

• ./scripts/build/cardano-sl.sh blockchain-importer
• printf "wallet:\n relays: [[{ host: relays.cardano-mainnet.iohk.io }]]\n valency: 1\n fallbacks: 7" > "/tmp/topology.yaml"
• stack exec -- cardano-blockchain-importer --topology "/tmp/topology.yaml" --log-config "blockchain-importer/log-config.yaml" --logs-prefix "logs/mainnet" --db-path db-mainnet --keyfile "secret-mainnet.key" --configuration-file "lib/configuration.yaml" --configuration-key mainnet_full --postgres-name ${POSTGRES_NAME} --postgres-password ${POSTGRES_PASSWORD}

The commands for building with nix will be added on a later stage. Note that the project has NO full support for the mainnet, for now the project is intended to be used only on the Cardano testnet.

Hi @ntallar

Thank you so much for your quick support. But I don't really understand what you mean about not supporting for mainnet, because I built and ran blockchain-importer successfully with mainnet and didn't know how to do the same thing with testnet.

@congle-ibl The importer was tested and works with the mainnet, what I meant that you should just be careful about using this with the extension that you'll be moving funds on the mainnet.

@ntallar Thank you so much for your help
