Can't build stack project #39

Closed jpathy closed 5 years ago

jpathy commented 5 years ago

On lts-13.28 stack2nix: user error (No such package ALUT-2.4.0.3 in the cabal database. Did you run cabal update?)

nh2 commented 5 years ago

Did you see #36 and #37? Do they help?

jpathy commented 5 years ago

Thanks using a snapshot of this month worked. Now my binary uses direct-sqlite with systemlib, i get linker failure:

/nix/store/ljx5sayk6w0bpd1ahcf0rm5fj55cqafd-binutils-2.31.1/bin/ld: cannot find -lsqlite3
collect2: error: ld returned 1 exit status
`cc' failed in phase `Linker'. (Exit code: 1)

@jpathy Is it an open-source project, so I could try building it?

If not, is it possible for you to strip it down to just some hello-world program with the sqlite dependency?

Also just to confirm, you were xdxd on IRC, right?

I tried to test this by adding a direct-sqlite dependency to static-stack2nix-builder-example, but didn't get far enough because with this patch:

I get the well-known and dreaded failure:

Determined cabalPackageId as Cabal-2.4.1.0-9MZFDeNrcJI10bcroa6pq8
setupCompileFlags: -package-id Cabal-2.4.1.0-9MZFDeNrcJI10bcroa6pq8
<command line>: cannot satisfy -package-id Cabal-2.4.1.0-9MZFDeNrcJI10bcroa6pq8
    (use -v for more information)

Looks like one more case where my overriding to use patched Cabal isn't perfect yet (brought to light because direct-sqlite somehow recursively depends on Cabal).

jpathy commented 5 years ago

Attached is an example project. I didn't get the cabal problem, it did compile the patched cabal for me.

test.zip

Yes, i don't directly depend on direct-sqlite, but i pass systemlib flag, so it doesn't link to the amalgamated sqlite on their repo.

nh2 commented 5 years ago

I've found the solution.

https://github.com/nh2/static-haskell-nix/blob/71d3aaa533687c2b11091f04b8a2abddfe8b99af/static-stack2nix-builder/default.nix#L35

Uses just .pkgs, not the pkgsWithArchiveFiles that have the sqlite that's overriden to have .a files.

I'll push a fix soon.

PR in #41

nh2 commented 5 years ago

@jpathy PR merged. Please try with the latest static-haskell-nix, and reopen if it still doesn't work (it does work for me now).

jpathy commented 5 years ago

It works now. Thanks for figuring it out.

nh2 commented 5 years ago

Great! Sorry it took so long; was a bit unfortunate with some holidays in between.
