#3151: Hello World does not compile (missing Prelude?)
--------------------+-------------------------------------------------------
Reporter: fft1976 | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.10.1 | Severity: normal
Keywords: | Testcase:
Os: Linux | Architecture: x86
--------------------+-------------------------------------------------------
Note: This is actually 6.10.2 (the Ticket Properties does not give this
choice)
{{{
$ cat hello.hs
main = do
putStrLn "Hello, World"
$ which ghc
/home/t/local/bin/ghc
$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 6.10.2
$ ghc --make hello
[1 of 1] Compiling Main ( hello.hs, hello.o )
hello.hs:1:0:
Failed to load interface for `Prelude':
Use -v to see a list of the files searched for.
}}}
Ubuntu 8.04 GHC 6.8.2 works though:
{{{
$ /usr/bin/ghc --version
The Glorious Glasgow Haskell Compilation System, version 6.8.2
$ /usr/bin/ghc --make hello
[1 of 1] Compiling Main ( hello.hs, hello.o )
Linking hello ...
$ ./hello
Hello, World
}}}
{{{
$ ghc -v --make hello
}}}
Prints lots of stuff, including:
{{{
hello.hs:1:0:
Failed to load interface for `Prelude':
locations searched:
Prelude.hs
Prelude.lhs
}}}
Indeed, Prelude seems to be missing:
{{{
$ cd ~/local/lib/ghc-6.10.2/
$ find . -name \*elude\*
}}}
I can also confirm another bug report (the reason is likely the same):
{{{
$ ghci
GHCi, version 6.10.2: http://www.haskell.org/ghc/ :? for help
ghc: panic! (the 'impossible' happened)
(GHC version 6.10.2 for i386-unknown-linux):
interactiveUI:setBuffering2
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
