Dear all, consider a simple test program: let _ = Printf.printf "Hello world!\n" I can generate the relevant assembly just fine, e.g.: ocamlopt -dstartup -S test.ml gcc -c a.out.startup.s -c But I cannot link it: gcc a.out.startup.o -L$(ocamlc -where) -lasmrun_shared .... a.out.startup.o(.data+0x6e8): error: undefined reference to 'camlStd_exit__frametable' collect2: Fehler: ld gab 1 als Ende-Status zurück distcc[9960] ERROR: compile (null) on localhost failed It seems that the whole Pervasives is missing (which is kind of expected). How do I link it, manually? Where are the relevant object files? thanks, Christoph
