I really have no idea. I am the new plugins maintainer -- but so far
that mostly means I am willing to apply darcs patches and uploading
things to hackage. I have not had a chance to really dig into plugins.
I will now make some wild guesses.
1. does it matter if you compile with -O2 vs -O0 ?
2. do those .o files actually exist?
3. Are there perhaps .o and .hi files in your project directory that
were compiled with GHC 7.0 but now you are trying to load them with >=
7.0?

Hi,
I'm currently working on extending the hascat Server. My problem is, that for whatever odd reason it will only work on GHC < 7.0 or alternatively if I execute it with runghc or in ghci. If I compile it with GHC>=7.0 and execute it, then I get this:
$ ~/.cabal/bin/hascat config.xml Installing "Root" at / hascat: /home/tvh/.cabal/lib/plugins-1.5.2.1/ghc-7.4.1/HSplugins-1.5.2.1.o: unknown symbol `ghczm7zi4zi1_ErrUtils_zdsinsertzugo3_info' hascat: unloadObj: can't find `/usr/lib/ghc/binary-0.5.1.0/HSbinary-0.5.1.0.o' to unload user error (unloadObj: failed) Installing "Hascat Server Info" at /ServerInfo/ hascat: /home/tvh/.cabal/lib/hascat-system-0.2/ghc-7.4.1/HShascat-system-0.2.o: unknown symbol `base_DataziMaybe_Nothing_closure' hascat: unloadObj: can't find `/usr/lib/ghc/Cabal-1.14.0/HSCabal-1.14.0.o' to unload user error (unloadObj: failed) Installing "Hascat Application Manager" at /Manager/ hascat: /home/tvh/.cabal/lib/hascat-system-0.2/ghc-7.4.1/HShascat-system-0.2.o: unknown symbol `base_DataziMaybe_Nothing_closure' hascat: unloadObj: can't find `/usr/lib/ghc/Cabal-1.14.0/HSCabal-1.14.0.o' to unload user error (unloadObj: failed) Installing "Hascat Application Deployer" at /Deployer/ hascat: /usr/lib/haskell-packages/ghc/lib/zlib-0.5.3.3/ghc-7.4.1/HSzlib-0.5.3.3.o: unknown symbol `base_GHCziForeignPtr_ForeignPtr_con_info' hascat: unloadObj: can't find `/usr/lib/ghc/Cabal-1.14.0/HSCabal-1.14.0.o' to unload user error (unloadObj: failed) Waiting for connections on port 8012
Is there a way to make this work?
