Custom setup breaks GHCJS version detection

[cocreature]

When building a package which uses a custom setup (e.g. http-api-data) the build fails after trying to run the custom setup due to

Build profile: -w ghcjs-0.2.1 -O0
In order, the following will be built:
 - http-api-data-0.3.7.1 (lib:http-api-data) (configuration changed)

Configuring http-api-data-0.3.7.1...
Warning: cannot determine version of
/home/moritz/code/haskell/ghcjs/.cabal-sandbox/bin/ghcjs :
"Linking a.jsexe ()\n"
setup: The program 'ghcjs' version >=0.1 is required but the version of
/home/moritz/code/haskell/ghcjs/.cabal-sandbox/bin/ghcjs could not be
determined.

It seems like it’s looking at the wrong output of ghcjs, ghcjs --numeric-ghcjs-version outputs 0.2.1 as expected. Afaict (using ghcjs-pkg and cabal-plan) the custom setup is built against Cabal-1.24.0.0. I installed ghcjs from the ghc-8.0 branch.

This issue is reproducible with new-build and sandboxes on both cabal-install-1.24 and cabal-install-HEAD.

Is it possible to strace -e process and post the trace? I'm curious what the actual invocation is. Also, if you can figure out what version of Cabal library the setup script is being linked against, that would also be helpful. (I don't have a ghcjs install handy so it is difficult for me to try repro'ing)

[cocreature]

Here’s an strace of running the setup https://gist.githubusercontent.com/cocreature/0576db3ab4cf3c4e6bfdc7a693d890b1/raw/cfcea7fb6041602fd2bac1bb29a87df914400367/gistfile1.txt Sadly I’m unable to spot anything useful. It looks like it’s never even calling something like ghcjs --numeric-ghcjs-version.

Setup.hs is linked against Cabal-1.24.0.0 (according to cabal new-build -v3).

[cocreature]

Closing since it looks like this probably related to using the wrong version of node ghcjs/ghcjs#470
