Hi, I'm trying to build OCaml 3.11.1 using Cygwin. It's still unsuccessful. $ make -f Makefile.nt world cd byterun ; make -f Makefile.nt all make[1]: Entering directory `/cygdrive/c/cygwin/home/ocaml-3.11.1/byterun' gcc -mno-cygwin -DOCAML_STDLIB_DIR='"C:/ocamlmgw/lib"' -I"C:\cygwin\bin" -O -mms -bitfields -Wall -Wno-unused -c interp.c gcc: The -mno-cygwin flag has been removed; use a mingw-targeted cross-compiler. make[1]: *** [interp.o] Error 1 make[1]: Leaving directory `/cygdrive/c/cygwin/home/ocaml-3.11.1/byterun' make: *** [coldstart] Error 2 I don't understand. I already installed the mingw package. What's wrong here? -- --Andre
