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?
I am on Centos7 by the way
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…
here the official from haskell for ghc -
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

the build is running perfectly 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”
glad to hear. best of luck and wishes!
I am using ubuntu
