#1779: unknown symbol `hs_hpc_module'
---------------------------------+------------------------------------------
Reporter: guest | Owner: AndyGill
Type: bug | Status: reopened
Priority: low | Milestone: 6.10.2
Component: GHCi | Version: 6.9
Severity: minor | Resolution:
Keywords: hpc | Difficulty: Unknown
Testcase: hpc_ghc_ghci | Os: Unknown/Multiple
Architecture: Unknown/Multiple |
---------------------------------+------------------------------------------
Changes (by igloo):
* testcase: => hpc_ghc_ghci
Comment:
I've made a minimal testcase, `hpc_ghc_ghci`.
In `libraries/hpc/tests/ghc_ghci`:
{{{
$ ../../../../ghc/stage2-inplace/ghc -v0 --interactive B.hs
*B> b
<interactive>: ./A.o: unknown symbol `hs_hpc_module'
$ ../../../../ghc/stage2-inplace/ghc -v0 --interactive B.hs
../../../../rts/Hpc.o
GHCi runtime linker: fatal error: I found a duplicate definition for
symbol
hs_hpc_rootModule
whilst processing object file
../../../../rts/Hpc.o
This could be caused by:
* Loading two different object files which export the same symbol
* Specifying the same object file twice on the GHCi command line
* An incorrect `package.conf' entry, causing some object to be
loaded twice.
GHCi cannot safely continue in this situation. Exiting now. Sorry.
}}}
