Stack ide doesn't work with stack on lts-3.0

[rvion]

Stack ide doesn't seem work with stack on lts-3.0

All details here lukexi/stack-ide-sublime#9 (I previously thought it was on sublime-stack-ide side)

Repro

1. pulled master of stack, stack-ide, and stack-ide-sublime
2. reinstalled stack and stack-ide, after setting: resolver: lts-3.0 in all stack.yaml files
3. generated brand new test project: stack new supernova && cd supernova && stack build && stack ide start supernova

and got that

⚠️ as @lukexi pointed out:

errors sometimes don't appear til you nudge stack-ide with a query like {"tag":"RequestGetSourceErrors","contents":[]} which you can just paste on the command line

Indeed, to see the error, you have to paste {"tag":"RequestGetSourceErrors","contents":[]} into the shell

Same problem here. I thought #48 fixed that, but appeared not the case in my machine.

Fixed this in commercialhaskell/stack@6ac73da.

Although I have now discovered a more ominous problem of the cabal_macros.h file somehow appearing in the module files leading to the same kind of result.

@chrisdone Thanks, it works now for me 👍

[chrisdone]

Yay, fixed the other issue too in commercialhaskell/stack@1f0d455.

[rvion]

confirmed ! Perfect 👍
