3007	GHC seems to ignore the package name of modules imported with {#- SOURCE #-}	jeltsch	igloo	"I have attached an archive with source bundles of two small Cabal packages A and B. Please build and register package A by executing these commands in directory A:
{{{
runghc Setup.lhs configure --user
runghc Setup.lhs build
runghc Setup.lhs register --inplace
}}}
Now try to build B by executing these commands in directory B:
{{{
runghc Setup.lhs configure --user
runghc Setup.lhs build
}}}
You will probably get the following error message:
{{{
B.hs:6:9:
    Bad interface file: .../Bug/A/dist/build/Internal.hi-boot
        .../Bug/A/dist/build/Internal.hi-boot:
            openBinaryFile: does not exist (No such file or directory)
    In the type `A'
    In the type signature for `a':
      a :: A
}}}

The type {{{A}}} is indirectly imported from module {{{Internal}}} of package A. GHC seems to think that this module was imported with a {{{{-# SOURCE #-}}}} pragma and therefore looks for a .hi-boot file instead of a .hi file. However, it’s the module {{{Internal}}} ''of package B'' that was imported with a {{{{-# SOURCE #-}}}} pragma."	bug	closed	normal	6.12.1	Compiler	6.10.1	fixed			Linux	x86_64 (amd64)		Unknown	driver/T3007
