Hi All, I tried to install Ocaml Version 3.05 on Windows XP using cygwin 2.0. After ./congifure, "make world" complains: rm -f argl.ppo Signal 11 make[3]: *** [crc.cmo] Error 139 make[3]: Leaving directory `/cygdrive/c/ocaml-3.05/camlp4/ocaml_src/camlp4' make[2]: *** [compile_cold] Error 2 make[2]: Leaving directory `/cygdrive/c/ocaml-3.05/camlp4' make[1]: *** [boot/camlp4.exe] Error 2 make[1]: Leaving directory `/cygdrive/c/ocaml-3.05/camlp4' make: *** [camlp4out] Error 2 Anyone has similar problem? But self-installing native port works. Thank you very much, Yu
