#3951: Unknown symbol error when ghci tries to load package scion
------------------------+---------------------------------------------------
Reporter: greenrd | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.12.1 | Keywords:
Os: Linux | Testcase:
Architecture: x86 | Failure: None/Unknown
------------------------+---------------------------------------------------
If you add scion to your flags in ~/.cabal/config, and then do the
following:
{{{
git clone git://github.com/greenrd/scion.git
cd scion
git checkout devel # DON'T OMIT THIS LINE!!!
cabal install
cd ..
darcs get --lazy http://code.haskell.org/yi/
cd yi
}}}
and then make the following change to yi.cabal
{{{
-- requires an unreleased version atm.
if flag (scion)
- build-depends: ghc == 6.10.*
+ build-depends: ghc >= 6.10.1
build-depends: ghc-syb
build-depends: scion
cpp-options: -DSCION
}}}
and then do cabal install, you should get, after some time, when it gets
around to compiling yi itself:
{{{
Loading package multiset-0.2 ... linking ... done.
Loading package network-bytestring-0.1.2.1 ... linking ... done.
Loading package uniplate-1.4 ... linking ... done.
ghc: /home/greenrd/.cabal/lib/scion-0.1.0.3/ghc-6.12.1/HSscion-0.1.0.3.o:
unknown symbol
`scionzm0zi1zi0zi3_ScionziTypesziOutline_OutlineDef_con_info'
Loading package scion-0.1.0.3 ... linking ... ghc: unable to load package
`scion-0.1.0.3'
cabal: Error: some packages failed to install:
yi-0.6.2.2 failed during the building phase. The exception was:
ExitFailure 1
}}}
(I had to make a couple of changes from upstream scion to make scion
compile together with yi, and those are in my repository.)
Although, to save time, you probably DON'T need to go to the trouble of
trying to compile yi - I'd hazard a guess that the bug occurs in the
compilation of scion, not the compilation of yi.
I did "cabal clean" in the scion directory and tried again - same result.
