Problem with installation #3

Open generalizedeigenvector opened 1 year ago

generalizedeigenvector commented 1 year ago

I am trying to install YATES on an Ubuntu machine and I've followed the installation guide closely. At the very last stage, when running the make command I get a nasty error I don't quite know how to resolve:

time -p jbuilder build @install
File "_build/.digest-db", line 1, characters 31-31:
Error: s-expression followed by data
Command exited with non-zero status 1
real 0.01
user 0.01
sys 0.00
Makefile:4: recipe for target 'build' failed
make: *** [build] Error 1

The only vaguely relevant piece of information I managed to find is this: https://stackoverflow.com/a/36903522/1813736 - but I don't see how it helps.

The file _build/.digest-db seems to be binary so I am at a loss how to fix this.

Any suggestions will be highly appreciated.

Oops. This project uses an outdated build system. We need to port it to Dune. I'll work on that now.

jnfoster commented 1 year ago

I ported the build system to Dune and updated for modern versions of the Jane Street OCaml libraries.

Can you try again?

jnfoster commented 1 year ago

If you try 

opam pin add yates https://github.com/cornell-netlab/yates.git

and then follow the prompts, it should work. Please let me know if you have issues with dependencies. It works on my system, but it is possible I missed some.

Thanks for getting back to me. It's still not quite working. I re-cloned the yates repo and when I try to run this line I get another error message:

The following dependencies couldn't be met:
  - yates ג†’ ocaml >= 4.12.0
      base of this switch (use `--unlock-base' to force)

[NOTE] Pinning command successful, but your installed packages may be out of
       sync.

I also tried to run this command which appears in the manual: dune external-lib-deps --missing @install and got another error message: dune: This subcommand is no longer implemented.

And I tried to simply run make again in the hope something would work but it claims that frenetic and other libraries are missing and says this in the end:

Warning: .dune files are ignored since 2.0. Reinstall the library with dune
>= 2.0 to get rid of this warning and enable support for the subsystem this
library provides.

But when I run dune --version I get 3.6.1.

So now I am even more confused...

Sorry, I lost track of this. Would you be able to try with a more up-to-date base OCaml installation? To do this, you would issue the command

ocaml switch create 4.12.0

and follow prompts, and then try again.
