Problem indexing xeno package #3

Closed qrilka closed 5 years ago

qrilka commented 5 years ago

It fails with the following message:

$ stack exec -- haskell-code-indexer -p ../xeno

It seems that file /home/qrilka/ws/h/xeno/.stack-work/dist/x86_64-linux-tinfo6/Cabal-2.0.1.0/setup-config doesn't exist. Does the directory /home/qrilka/ws/h/xeno/.stack-work/dist/x86_64-linux-tinfo6/Cabal-2.0.1.0/ exist?

Can you execute the command stack path --dist-dir in a directory with the source code of xeno package? stack path --dist-dir returns relative path of a dist-dir where setup-config file should be. (For example, I installed xeno-0.3.4 on my machine and the dist-dir is .stack-work/dist/x86_64-linux/Cabal-2.0.1.0).

Then you can try to add --dist option to haskell-code-indexer: stack exec -- haskell-code-indexer -p ../xeno --dist DIST_DIR

You're right, that was the case. Running stack build on the project fixed the problem. I think it's worth to document this requirement.

hasufell commented 5 years ago

That doesn't sound like a reasonable requirement to force everyone to use stack.

alexwl commented 5 years ago

Stack is not a requirement. It is possible to index packages built by cabal-install (cabal). You need Stack only to build haskell-code-indexer and haskell-code-server.
