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 <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

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!
Torsten
