I am building a new node. all goes well until i run this command and get a ghc error. cabal build cardano-cli cardano-node [root@ADA-host cardano-node]# cabal build cardano-cli cardano-node cabal: Cannot find the program ‘ghc’. User-specified path ‘ghc-8.10.2’ does not refer to an executable and the program is not on the system path. any ideas why it would not be able to find the program up to this point? ---

Did you download ghc and install/unpack it? Looks like you didn’t do install ghc/lib or the path is incorrect. You can reference the coincash guide but swap out the commands to be centos vs ubuntu as each os is slightly different… [https://www.coincashew.com/coins/overview-ada/guide-how-to-build-a-haskell-stakepool-node#1-install-cabal-and-ghc](https://www.coincashew.com/coins/overview-ada/guide-how-to-build-a-haskell-stakepool-node#1-install-cabal-and-ghc) here the official from haskell for ghc - [https://www.haskell.org/ghc/download\_ghc\_8\_10\_4.html](https://www.haskell.org/ghc/download_ghc_8_10_4.html) ---

Thank you! looks like i ran the command from an old article and used cabal configure --with-compiler=ghc-8.10.2 instead of cabal configure --with-compiler=ghc-8.10.4 now i am getting , these were the goals I’ve had most trouble fulfilling: cardano-crypto-class troubleshooting that now. ---

Hi! you can “close” the topic by mark one of the answer as solution - also the title of the topic can be improved by adding the error message itself. like - stake pool server help - “cannot find the ghc” ---
