Re: [Haskell-iPhone] Build error with ghc-8.2.2 for iOS

Hi Torsten, I believe those notes are bit dated. You might find https://medium.com/@zw3rk/a-haskell-cross-compiler-for-ios-7cc009abe208 https://medium.com/@zw3rk/ghc-cross-compiler-binary-distributions-490bb2c0c4... helpful. I hope to have a fresh set of better cross compiler binary distributions ready by the end of next week. Cheers, Moritz

Hello all,

I try to build ghc-8.2.2 based on a brew installed ghc (8.2.1) on macOS 10.13.1 with current Xcode. I follow the guidelines at https://ghc.haskell.org/trac/ghc/wiki/Building/CrossCompiling/iOS and come to an error at step 5 where

./configure CC=arm-apple-darwin10-clang --target=arm-apple-darwin10; make

is being executed.

The error reads…

arm-apple-darwin10-clang -E -DPROFILING -DTHREADED_RTS -DDEBUG -fno-stack-protector -Wall -Wall -Wextra -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Winline -Waggregate-return -Wpointer-arith -Wmissing-noreturn -Wnested-externs -Wredundant-decls -Iincludes -Iincludes/dist -Iincludes/dist-derivedconstants/header -Iincludes/dist-ghcconstants/header -Irts -Irts/dist/build -DCOMPILING_RTS -DUSE_LIBFFI_FOR_ADJUSTORS -fno-strict-aliasing -fno-common -Irts/dist/build/./autogen -Wno-unknown-pragmas -O2 -fomit-frame-pointer -g -DRtsWay=\"rts_v\" -Wno-strict-prototypes -MM -x c rts/linker/LoadArchive.c -MF rts/dist/build/.depend-v-l-debug-thr-thr_debug-thr_l.c_asm.bit clang: warning: optimization flag '-fomit-frame-pointer' is not supported for target 'armv7' [-Wignored-optimization-argument] rts/linker/LoadArchive.c:57:2: error: Unknown Darwin architecture #error Unknown Darwin architecture ^ 1 error generated. make[1]: *** [rts/dist/build/.depend-v-l-debug-thr-thr_debug-thr_l.c_asm] Error 1 make: *** [all] Error 2

This stems from the following code in rts/linker/LoadArchive.c…

static StgBool loadFatArchive(char tmp[static 20], FILE* f, pathchar* path) { uint32_t nfat_arch, nfat_offset, cputype, cpusubtype; #if defined(i386_HOST_ARCH) const uint32_t mycputype = CPU_TYPE_X86; const uint32_t mycpusubtype = CPU_SUBTYPE_X86_ALL; #elif defined(x86_64_HOST_ARCH) const uint32_t mycputype = CPU_TYPE_X86_64; const uint32_t mycpusubtype = CPU_SUBTYPE_X86_64_ALL; #elif defined(powerpc_HOST_ARCH) const uint32_t mycputype = CPU_TYPE_POWERPC; const uint32_t mycpusubtype = CPU_SUBTYPE_POWERPC_ALL; #elif defined(powerpc64_HOST_ARCH) const uint32_t mycputype = CPU_TYPE_POWERPC64; const uint32_t mycpusubtype = CPU_SUBTYPE_POWERPC_ALL; #elif defined(aarch64_HOST_ARCH) const uint32_t mycputype = CPU_TYPE_ARM64; const uint32_t mycpusubtype = CPU_SUBTYPE_ARM64_ALL; #else #error Unknown Darwin architecture #endif

It seems that the necessary architecture is not provided here?

Any help would be very much appreciated!

Thanks!
