GHC does not provide ARM NCG and so it is using > LLVM if you compile ARM registerised build. > But "./configure [...] --enable-unregisterised" should mean using the C backend, not LLVM, right? So this still looks strange. Also there is an explicit "-fllvm" on the failing ghc-stage1 command line. What is in your build.mk? Maybe you are using one of the build flavors that sets -fllvm explicitly? That said you can also try installing the supported version of LLVM for ghc 7.10, which is LLVM 3.5. Regards, Reid Barton
