What version of GHC did you build?
This was building from the ghc-7.4 branch. That being said, after this build finished I noticed that the resulting stage 2 compiler wasn't invoking llc with the correct parameters, resulting in the same linker error when doing builds. This might have been due to the fact that I changed `build.mk` several times mid-build. I'm currently waiting for a clean rebuild. However, I'm now using a more specific configuration as passing `-optlc-float-abi=hard` in `HC_SRC_OPTS` caused the stage 0 build to fail with, ... *** LLVM Compiler: 'llc-3.0' '-O1' '-relocation-model=static' '/tmp/ghc25792_0/ghc25792_0.bc' '-o' '/tmp/ghc25792_0/ghc25792_0.lm_s' '-float-abi=hard' '-mcpu=cortex-a9' '-mattr=+v7,+vfp3,+d16' '-float-abi=hard' llc-3.0: for the -float-abi option: may only occur zero or one times! I'm not really sure where this second `-float-abi=hard` is coming from, but using the following in `build.mk` works around the issue, SRC_HC_OPTS = -H64m -Rghc-timing GhcStage1HcOpts = -O -fvia-C GhcStage2HcOpts = -O0 -fllvm -keep-llvm-files -debug -DDEBUG -optc-mfloat-abi=hard -optc-mcpu=cortex-a9 -optlc-float-abi=hard -optlc-mcpu=cortex-a9 GhcLibHcOpts = -O -fllvm -optc-mfloat-abi=hard -optc-mcpu=cortex-a9 -optlc-float-abi=hard -optlc-mcpu=cortex-a9 The build is still in stage 1 so it is unclear whether this will fix the original linker error.
