error while building server

[rigille]

hi! i'm new to haskell and nix and i'm trying to build the server using nix, but I get the following error

$ make
./buildscripts/make-server.sh
--> Step 1 - Preparing nix-shell environment...
--> Step 2 - Runing: stack --no-nix-pure build --fast
error: attribute 'ghc865' missing, at (string):1:61
(use '--show-trace' to show detailed location information)
make: *** [Makefile:26: server] Error 1

which seems to be related to the ghc version. has someone experienced a similar error?

Thank you, @rigille!

I've just upgraded to a more recent nixpkgs and stackage release, could you try rebuilding from the latest master to see if it helps?

[rigille]

i appreciate you answered so fast 🙂 it did help, now i get a different error

--> Step 2 - Runing: stack --no-nix-pure build --fast

Error: While constructing the build plan, the following exceptions were encountered:

In the dependencies for happstack-server-7.5.1.3:
    network-3.1.1.1 from stack configuration does not match >2.6 && <2.9  (latest matching version is 2.8.0.1)
    template-haskell-2.15.0.0 from stack configuration does not match <2.15  (latest matching version is 2.14.0.0)
    time-compat-1.9.5 from stack configuration does not match ==0.1.*  (latest matching version is 0.1.0.3)
needed due to lojbanios-0.1.0.0 -> happstack-server-7.5.1.3

In the dependencies for papillon-0.1.0.6:
    template-haskell-2.15.0.0 from stack configuration does not match ==2.14.*  (latest matching version is 2.14.0.0)
needed due to lojbanios-0.1.0.0 -> papillon-0.1.0.6

Some different approaches to resolving this:

  * Set 'allow-newer: true' in /home/rigille/.stack/config.yaml to ignore all version constraints and build anyway.

  * Recommended action: try adding the following to your extra-deps in /home/rigille/repositories/haskell/lojban.io/stack.yaml:

- network-2.8.0.1@sha256:0f165dffa752d8cde30c2bde86f80609c4f1dc5eeb3182d593041f97839c5b3b,3011
- template-haskell-2.14.0.0@sha256:e3747ae9e2aeec160196706dd470b5fc4175678ec4136bcec9124534f67d83bc,1724
- time-compat-0.1.0.3@sha256:42a0a7d2f0d60467e388721a8b867caa7dff891cad20867d1211039716342087,861

Plan construction failed.
make: *** [Makefile:26: server] Error 1

so i tried to put allow-newer: true inside stack.yaml (without the extra-deps). the build process starts but it fails on papillon

[jqueiroz]

Sorry about that, and thanks again for the interest :)

I just made a few more changes, could you try again?

[rigille]

third time's the charm .ui .u'a i already can run the server locally. just had to increase my swap a bit because i ran out of memory building zasni gerna at first .u'i

[jqueiroz]

Awesome!

Yeah, zasni-gerna takes a lot of memory to build haha
