Success! Since OMake doesn't really have a notion of a build environment, just one of platform (UNIX or Win32), compiling the latest release (0.9.8.5-3) from sources requires a number of modifications to the makefiles. Furthermore, OCaml has incorporated a number of warnings that make necessary adjusting some command-line parameters.
Note: These steps are specifically for the MinGW port of OCaml. If you're trying to build with OCaml/Cygwin, you'd want to keep most of the settings in the makefiles intact, except for adjusting the OCaml warnings. YMMV.
Here are the steps I followed for a clean build from sources:
- Make sure that your Cygwin environment is sane. In particular, prune from your $PATH variable all entries with spaces, make sure that $OCAMLLIB is properly set and eliminate the $OMAKELIB variable if present. Also, using Cygwin under Windows Vista or Windows 7 is fraught with privilege peril; set your $TMP variable to Cygwin's /tmp directory
- Download and unpack omake-0.9.8.5-3.tar.gz to Cygwin's root /
- Apply the source patches detailed here:

- omake_exec.ml.patch:
- Patch the Makefile with the following Makefile.patch:

These modifications account for MinGW applications's inability to read from symbolic links, and the need to use .exe as the executable files's extension.
- Patch src/Makefile with the following src_Makefile.patch:
--- src/Makefile.orig 2007-06-27 20:59:16.000000000 -0300 +++ src/Makefile 2010-08-16 13:26:35.342346000 -0300 @@ -7,32 +7,32 @@ # # System config # -LN = ln -sf +LN = cp RM = rm -f DOT = ./ slash = / -win32 = unix -system = null +win32 = win32 +system = system # # C configuration # -CC = cc -CFLAGS = +CC = gcc +CFLAGS = -mno-cygwin -I"$(OCAMLLIB)" -DWIN32 -DFAM_ENABLED -DFAM_PSEUDO AR = ar cq AROUT = EXT_OBJ = .o EXT_LIB = .a -EXE = +EXE = .exe -OCAMLFLAGS = -THREADSLIB = +OCAMLFLAGS = -thread +THREADSLIB = threads.cma .SUFFIXES: .mll .mly .mli .ml .c .cmi .cmo .cma .o .c.o: - $(CC) $(CFLAGS) -I"`ocamlc -where`" -c $*.c + $(CC) $(CFLAGS) -c $*.c #
Again, this accounts for the fact that MinGW applications under Cygwin are Windows applications with UNIX syntax.
- Patch OMakeroot with the following OMakeroot.patch:

The rationale behind these modifications can be found in this message. In short, it tricks the initial configuration into thinking it's a UNIX platform, and then reverts to the Win32 port, setting a variable for OMakefile.
- Patch OMakefile with the following OMakefile.patch:
--- OMakefile.orig 2010-08-16 13:29:07.788616600 -0300 +++ OMakefile 2010-08-16 13:29:13.828708200 -0300 @@ -15,7 +15,14 @@ # # Extra options for the C compiler # - CFLAGS += /MT /DWIN32 /W4 /WX + if $(equal $(TOOLCHAIN), MinGW) + CFLAGS += -DWIN32 + FAM_CFLAGS = -DFAM_ENABLED -DFAM_PSEUDO + export + + else + CFLAGS += /MT /DWIN32 /W4 /WX + export # # Don't build man pages @@ -57,7 +64,7 @@ # # OCaml options # -OCAMLFLAGS[] += -w Ae$(if $(OCAML_ACCEPTS_Z_WARNING), z) +OCAMLFLAGS[] += -w Ae$(if $(OCAML_ACCEPTS_Z_WARNING), z)-9-27..29 if $(THREADS_ENABLED) OCAMLFLAGS += -thread exportThis modification has two parts. First, it detects the MinGW toolchain to change the command line syntax of some of the build options. Second, it adjusts the OCaml warning flags so that the source compiles under 3.12.
- Do make bootstrap
- Edit .config to set your installation root
- Do make all
- Do make install
Good luck!
