Hi guys,
I am working on running Cardano SL from source.
I get to running this command:
$ nix-build -A cardano-sl-node-static --cores 0 --max-jobs 2 --no-build-output --out-link master
but it fails with this error:
error: attribute ‘cardano-sl-node’ in selection path ‘cardano-sl-node’ not found
anyone knows why cardano-sl-node attr is missing?
Thanks in advance

Try building it with cardano-sl-static
$ nix-build -A cardano-sl-static --cores 0 --max-jobs 2 --no-build-output --out-link master
See this PR
please update the document
https://github.com/input-output-hk/cardano-sl/blob/develop/docs/how-to/build-cardano-sl-and-daedalus-from-source-code.md
for what it is worth I use -A cardano-sl-wallet to build the node see default.nix for targets.
Build on Ubuntu 16.04 with stack works fine.
Just add nix settings into stack configuration and follow Stack with Nix for system libraries (mixed mode) Instruction.

thanks guys. perfect ! I managed to build it now. I have a new questions now. I get the following error after running the node:
ConfigurationParseFailure “node/configuration.yaml” (InvalidYaml (Just (YamlException “Yaml file not found: node/configuration.yaml”)))
Any ideas ? I found a list of all parameters as part of documentation but I can really get my head around using it properly.
What I am suppose to do next ? any help is appreciated.
can you copy it from ./lib/configuration.yaml
judging from the error message, I would say you haven’t the file node/configuration.yaml.
Here original node/configuration.yaml.
@h4ck3rm1k3 wrote a very helpful installation instruction. Just follow it to avoid troubles.
Thanks this ^^ worked for me too.
Now when I run master/bin/cardano-node-simple I get error:
cardano-node-simple: MissingSystemStartTime
So a little research shows me this Issue gives hints to the solution. I’ll post a new thread if I can’t solve it. I’ll try to make a tutorial covering all these issues once I’m done.
@devcap: That’s my issue on Github 
The solution is quite simple. There is a script you need to build that starts your node and connect it to the mainnet. You build the script with this:
nix-build -A connectScripts.mainnetWallet -o connect-to-mainnet
@Raha_Mohebbi idk if this will work for you, but if I run master/bin/cardano-node-simple then I DON’T get your yaml error, but if I cd into master and then run bin/cardano-node-simple then I get your exact yaml error. So maybe try running the node from project root
@zmeel
Thanks I ran nix-build -A connectScripts.mainnetWallet -o connect-to-mainnet like you said and it completed after a few minutes. It created this script which I ran:
./connect-to-mainnet
@devcap And? Did your node work? Did it connect to the mainnet?
yes, it did run successfully! Lots of cool activity going on in the log. I think next I’ll lookup the API and try to work with it from command-line.
Next:
I want to understand better how this differs from the stuff in cardano-sl/scripts/launch and cardano-sl/scripts/launch/connect-to-cluster as it sounds similar and is referenced in cardanodocs.com/technical/launcher. Any ideas? I’ll research and try to follow those instructions too.
I also want to understand how or why the wallet is a separate application. When I ran a full bitcoin node a while ago, the features were all part of the same Bitcoin Core program, I believe. You can also run a bitcoin ‘lite node’ which is like a limited full node, for wallet functionality only.
I think the wallet is just a nice interface for the node. With the connect-to mainnet script you start a node-with-wallet. Most/all of the API’s are for wallet handling.
what OS are you guys using ? Win/Linux/OSX ?
Linux and OSX
fyi everyone: The build process on OSX is surprisingly easy!
where can i find the cert file for postman?
