Issue #72 describes the same problem. I have just done some tests and compared between gsc from the installer and HomeBrew Ok here is the error message : The full verbose (gsc -verbose test.scm)Parsing: fact-aux fact Compiling: fact-auxfact Dumping: #<primitive | test|> #<procedure fact-aux> #<procedure fact> Compilation finished.gcc -arch x86_64 -m64 -arch x86_64 -m64 -bundle -Wno-unused -Wno-write-strings -O1 -fno-math-errno -fschedule-insns2 -fno-trapping-math -fno-strict-aliasing -fwrapv -fomit-frame-pointer -fPIC -fno-common -mieee-fp -flat_namespace -undefined suppress -D___SINGLE_HOST -D___DYNAMIC -I"/Library/Gambit-C/v4.7.2/include" -o "test.o1" test.c clang: error: unknown argument: '-fschedule-insns2' [-Wunused-command-line-argument-hard-error-in-future]clang: note: this will be a hard error (cannot be downgraded to a warning) in the future*** ERROR IN ##main -- C compilation or link failed while compiling "test.scm" Here is the code:;(standard-bindings) (extended-bindings) (block))(define (fact-aux n a) (if (<= n 1) a (fact-aux (- n 1) (* a n)))) (define (fact n) (fact-aux n 1)) **************************************************Then I reinstalled the HomeBrew gambit and I got this : Parsing: fact-aux fact Compiling: fact-auxfact Dumping: #<primitive | test|> #<procedure fact-aux> #<procedure fact> Compilation finished.clang -bundle -Wno-unused -Wno-write-strings -O1 -fno-math-errno -fno-strict-aliasing -fwrapv -fomit-frame-pointer -fPIC -fno-common -flat_namespace -undefined suppress -D___DYNAMIC -I"/usr/local/Cellar/gambit-scheme/4.7.2/include" -o "test.o1" test.c ************************** to compare with (from the installer)gcc -arch x86_64 -m64 -arch x86_64 -m64 -bundle -Wno-unused -Wno-write-strings -O1 -fno-math-errno -fschedule-insns2 -fno-trapping-math -fno-strict-aliasing -fwrapv -fomit-frame-pointer -fPIC -fno-common -mieee-fp -flat_namespace -undefined suppress -D___SINGLE_HOST -D___DYNAMIC -I"/Library/Gambit-C/v4.7.2/include" -o "test.o1" test.c *************************************************** To my surprise the HomeBrew gsc uses clang and not the gcc-4.2 though it was given the path at installation.

Hi,
I tried to install gambit with the installer. The interpreter worked, the compiler failed to compile a simple file (xcode and its command lines tools were installed). I finally installed apple's old gcc4.2 and then gambit with HomeBrew (the gambit formula allows to specify a compiler) and it seems to work fine. Well I might get some problems when linking with some 10.9 libs, I have no idea whether apple's previous and present compilers produce compatible binaries or not.
Any thoughts, similar troubles related to this topic?
Thanks,
Denis
Can you open an issue for this on github? (https://github.com/feeley/gambit/issues)
It would help if you could give the error messages that were produced. You should try to call gsc with the -verbose option so that the invocations of the C compiler are shown.
