Okay, I patched the settings filed generted by ./configure in the binary-dist and rank make install which completed. However,

Damn it. So close. I don't know how make install succeded without segfaulting.
Sigh! Go back to your build tree and try the same thing with inplace/bin/ghc-stage2 and let us know if this works or not. BTW: What's in Main.hs?
pi@raspberrypi /tmp $ ghc-7.6.1c/inplace/bin/ghc-stage2 Main.hs [1 of 1] Compiling Main ( Main.hs, Main.o ) Linking Main ... pi@raspberrypi /tmp $ ./Main Hello World.
The stage2 compiler works fine inplace.
OK, so binary-dist not only corrupted your settings file, but also somehow your compiler. Nice to see you are able to get working compiler on your RPi board. Congratulations! :-)
Thanks. :)
So the binary-dist has a settings.in file. It is the configure step in the binary-dist that generates the corrupt settings file.
I'll try to poke around to see where and why the stage2 compiler and the binary-dist compiler differ.
I replaced the lib/ghc-7.6.1/settings built from the binary-dist which read: [("GCC extra via C opts", " -fwrapv"), ("C compiler command", "/usr/bin/gcc"), ("C compiler flags", " -fno-stack-protector "), ("ar command", "/usr/bin/ar"), ("ar flags", "q"), ("ar supports at file", "@ArSupportsAtFile@"), ("touch command", "touch"), ("dllwrap command", "/bin/false"), ("windres command", "/bin/false"), ("perl command", "/usr/bin/perl"), ("target os", "OSLinux"), ("target arch", "ArchARM {armISA = ARMv6, armISAExt = [VFPv2], armABI = HARD}"), ("target word size", "4"), ("target has GNU nonexec stack", "False"), ("target has .ident directive", "True"), ("target has subsections via symbols", "False"), ("LLVM llc command", "llc"), ("LLVM opt command", "opt") ] With the settings file from the build: [("GCC extra via C opts", " -fwrapv"), ("C compiler command", "/usr/bin/gcc"), ("C compiler flags", " -fno-stack-protector -Wl,--hash-size=31 -Wl,--reduce-memory-overheads"), ("ar command", "/usr/bin/ar"), ("ar flags", "q"), ("ar supports at file", "YES"), ("touch command", "touch"), ("dllwrap command", "/bin/false"), ("windres command", "/bin/false"), ("perl command", "/usr/bin/perl"), ("target os", "OSLinux"), ("target arch", "ArchARM {armISA = ARMv6, armISAExt = [VFPv2], armABI = HARD}"), ("target word size", "4"), ("target has GNU nonexec stack", "False"), ("target has .ident directive", "True"), ("target has subsections via symbols", "False"), ("LLVM llc command", "/usr/bin/llc-3.0"), ("LLVM opt command", "/usr/bin/opt-3.0") ] and now ghc builds executables that do not segfault! It seem that the configure program in the binary-dist needs some patching. -- 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.''
