Happy to provide any other info that would be helpful. I didn't see any install instructions other than just building from source so I feel like I'm probably just missing a dependency or something. Any assistance would be much appreciated!

Hey @jmorganca, I'm running go version go1.21.0 linux/amd64. Is there a different version I should be using? Thank you for your help!

This may be from building without cgo:

CGO_ENABLED go build .

You may need to install gcc/g++:

sudo apt install build-essential

Hey, thanks so much. I think it was just that I needed build-essential; it wouldn't build with just CGO_ENABLED, but built just fine with it after also installing build-essential for gcc. Thanks a ton for your help!

Including another console log for posterity toward anyone finding this issue in the future. :)

ubuntu@machine:~/ollama$ CGO_ENABLED go build .
CGO_ENABLED: command not found

ubuntu@machine:~/ollama$ CGO_ENABLED=1 go build .
# runtime/cgo
cgo: C compiler "gcc" not found: exec: "gcc": executable file not found in $PATH

ubuntu@:~/ollama$ sudo apt-get install build-essential
[output snipped]

ubuntu@machine:~/ollama$ CGO_ENABLED go build .
CGO_ENABLED: command not found

ubuntu@machine:~/ollama$ CGO_ENABLED=1 go build .

ubuntu@machine:~/ollama$ ls

LICENSE     api        cmd  examples  go.mod  llm     ollama   progressbar  server

Built successfully with CGO_ENABLED=1 go build . and now I have the ollama binary. Thanks again!
