Can't build Cardano node

Staking & Delegation Setup a Stake Pool
1

Hello. Trying to set up stake pool server. Installing on Ubuntu Desktop 22.04 LTS. I’m using the coincashew guide.
Running the installation process as on testnet.
I’ve gone through the steps, past installing GHC and Cabal. Verifying both after installing. Then I get to the compiling steps.
First I run:
git clone GitHub - input-output-hk/cardano-node: The core component that is used to participate in a Cardano decentralised blockchain.
cd cardano-node
git fetch --all --recurse-submodules --tags

Then I try to run the command:
cabal build cardano-node cardano-cli

I get this outcome:
Warning: Requested index-state 2022-10-25T20:00:00Z is newer than
‘cardano-haskell-packages’! Falling back to older state
(2022-10-25T17:33:07Z).

After searching the rest of the dependency tree exhaustively, these were the
goals I’ve had most trouble fulfilling: base, cardano-api

I’ve googled the details I can extract from it. But to no avail.
Here’s my ghc and cabal info.

ghc --version
The Glorious Glasgow Haskell Compilation System, version 9.4.4

cabal --version
cabal-install version 3.8.1.0
compiled using version 3.8.1.0 of the Cabal library

What am I missing? Thanks in advance.

use ghc-8.10.x (not 9.4.4).

I’m using

:~$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 8.10.7
:~$ cabal --version
cabal-install version 3.6.2.0
compiled using version 3.6.2.0 of the Cabal library
:~$

Did you do the install cabal and ghc steps right from the guide? Installing the Glasgow Haskell Compiler and Cabal - CoinCashew

re: Alex. I just installed the 8.10.7 version and then set that as the version to use. Then I ran the compiler again, and I got a similar if not identical error. I think I’m going to do a reinstall of the OS, and then start over now that you gave me something to go on.

re: jeremy
Yes, I was using that specific guide

Thank you both. I’ll keep you posted.

re: Alex- after I reinstalled the OS and ran through another attempt where I only installed that version of ghc the compiling command worked! Thank you!

Wow, you had to completely re-install the OS? ive got the same issue where it just wont compile. gotta be a way around this…

I think you might just have needed to do:

cabal update

before your ‘cabal build’ commands.

Reinstalling no doubt fixed the problem but I would want to know why. Reinstalling is an uneducated Windowsy way of fixing things.

I don’t understand about the use of index-state configuration in cabal.project but in that file you will see the following lines:

index-state: 2022-09-27T18:00:00Z
index-state: cardano-haskell-packages 2023-01-26T18:00:00Z

Index-state seems to be something that the IOG team configure via cabal.project. Maybe it tells cabal something about what state the build tree should be updated to??? Hopefully someone who knows more can enlighten both of us and maybe even explain why my compile is still complaining about an 8 minute difference (see below).

In any case, your message says this:

Warning: Requested index-state 2022-10-25T20:00:00Z is newer than
‘cardano-haskell-packages’! Falling back to older state
(2022-10-25T17:33:07Z).

When I just ran the compilation now following a ‘cabal update’, mine said:

Warning: Requested index-state 2023-01-26T18:00:00Z is newer than
'cardano-haskell-packages'! Falling back to older state
(2023-01-26T17:52:04Z).

You probabaly wish you could have your old install back now to test if a ‘cabal update’ is the correct fix.

Try the above.
