Hmm, are you using Raspbian? I.e. hard-float abi caught my eye in case of ARMv6/ARM11 chip here...
I'm afraid LLVM is not well guided in your case so could you be so kind and test if adding -optlc=-mattr=+vfp2 helps? You need to add it to your build.mk probably and you will need to rebuild everything again...
No change with SRC_HC_OPTS = -H64m -Rghc-timing -optc-mfloat-abi=hard -optc-march=armv6 -optc-mfpu=vfp -optlc=-mattr=+vfp2 GhcStage1HcOpts = -O -fllvm GhcStage2HcOpts = -O0 -fllvm GhcLibHcOpts = -O -fllvm I still get the error: ===--- building final phase make -r --no-print-directory -f ghc.mk phase=final all LD libraries/ghc-prim/dist-install/build/HSghc-prim-0.3.0.0.o /usr/bin/ld: error: libraries/ghc-prim/dist-install/build/cbits/debug.o uses VFP register arguments, libraries/ghc-prim/dist-install/build/HSghc-prim-0.3.0.0.o does not /usr/bin/ld: failed to merge target specific data of file libraries/ghc-prim/dist-install/build/cbits/debug.o I don't really understand what is going on here. The file libraries/ghc-prim/dist-install/build/HSghc-prim-0.3.0.0.o doesn't even exist, so when I manually run /usr/bin/ld I get: $ /usr/bin/ld libraries/ghc-prim/dist-install/build/HSghc-prim-0.3.0.0.o /usr/bin/ld: cannot find libraries/ghc-prim/dist-install/build/HSghc-prim-0.3.0.0.o: No such file or directory What is make really doing here? My research suggests that this error is a symptom of trying to link something without the hard-float ABI together with something with a soft-float ABI. But I don't know where libraries/ghc-prim/dist-install/build/HSghc-prim-0.3.0.0.o is coming from. -- Russell O'Connor http://r6.ca/ ``All talk about `theft,''' the general counsel of the American Graphophone Company wrote, ``is the merest claptrap, for there exists no property in ideas musical, literary or artistic, except as defined by statute.''
