So what does all this mean? May I avoid the whole problem by downloading version 3.05, or do I have to wait for 3.07?

I made the changes you mentioned below, but I still get this:
C:\ocaml>make -f Makefile.nt world
cd byterun ; make -f Makefile.nt all
gcc -mno-cygwin -DIN_OCAMLRUN -DOCAML_STDLIB_DIR='"C:/ocamlmgw/lib"' -O -Wall -W
interp.c
interp.c(215): jumptbl.h: No such file or directory
make[1]: *** [interp.d.o] Error 1
make: *** [coldstart] Error 2

So the file jumptbl.h is still missing. What should I do?

Re: [Caml-list] beginner's questions

[Hallvard Ystad]

OK, thanks. Things work better now. But there still is a problem. There seems to be noe file named "ocamlrun.a" anywhere, but it is required by byterun/Makefile.nt, line 43:
        $(CC) -o ocamlrun.exe main.$(DO) ocamlrun.$(A)

I get this error in the DOS console:
C:/mingw/bin/gcc -mno-cygwin -o ocamlrun.exe main.d.o ocamlrun.a
gcc: ocamlrun.a: No such file or directory
make[1]: *** [ocamlrun.exe] Error 1
make: *** [coldstart] Error 2

(I need to specify full path to gcc, because I have WebObjects installed on my computer, with an older version of gcc. It took a while to figure that out. WO has bugged me before, overriding my java paths, so I really wasn't all that surprised.)

Is ocamlrun.a really missing, or am I overlooking something again?

Thanks,
~H

They do. See readme.win32:

       Release notes on the MS Windows ports of Objective Caml
       -------------------------------------------------------

Starting with OCaml 3.05, there are no less than three ports of
Objective Caml for MS Windows available:
  - a native Win32 port, built with the Microsoft development tools;
  - a native Win32 port, built with the MinGW development tools;
  - a port consisting of the Unix sources compiled under the Cygwin
    Unix-like environment for Windows.

Here is a summary of the main differences between these ports:

                                      Native MS     Native MinGW        Cygwin
Third-party software required
  - for base bytecode system            none            none            none
  - for ocamlc -custom                  MSVC         MinGW or Cygwin    Cygwin
  - for native-code generation          MSVC+MASM    MinGW or Cygwin    Cygwin
[---cut---]

So if you are going to use ocamlopt from win32 binary distribution, you have
to install Microsoft Visual C and Microsoft Macro Assembler on your computer.

Again, the binary build expects Tcl/Tk 8.3 installed. To work with other
version you can rebuild the whole Ocaml from the sources.

Which one? E.g. module "Str" is already included into the standard library.

..or MinGW. I tried to compile ocaml with MinGW installed, and then got this error message (copied from console):
C:\ocaml>make -f Makefile.nt world
cd byterun ; make -f Makefile.nt all
gcc -mno-cygwin -DIN_OCAMLRUN -DOCAML_STDLIB_DIR='"C:/ocamlmgw/lib"' -O -Wall -Wno-unused -D_DLL -c interp.c
interp.c(215): jumptbl.h: No such file or directory
make[1]: *** [interp.d.o] Error 1
make: *** [coldstart] Error 2

So what did I miss now? It seems jumptbl.h isn't included in the distribution... Or am I mistaken again?

Actually, I was asking for a friend. He thinks it's called PCRE.

  jumptbl.h is generated from existing files.  I made it "by hand":
cd byterun && make -f Makefile.nt jumptbl.h
  before running "make world".

  But real problems begin further, at Dynlink module (generally at first
module when exception End_of_file needs to be got from stdlib.cma).
I can't cite the exact error message, but ocamlc can't find "End_of_file"
exception in "stdlib.cma(Pervasives)".
  Really, any small test program, which requires End_of_file, can't be
compiled, and the problem is not in bad paths to library/compiler.

  I'm using mingw 2.0 (gcc 3.2, binutils 2.13).

  Where I'm wrong?

Right, I believe this is a small bug in the 3.06 distribution
(the file byterun/.depend.nt should be in the distributed sources, but
isn't).

Probably the file bytecomp/runtimedef.ml was generated incorrectly,
maybe because you didn't use the correct version of "sed".  The
Win32 Makefiles are known to work with GNU sed as found in Cygwin, but
one user reported problems with another version of sed coming from
another Windows port of Unix tools.

  Thank you for help.  Yes, you are right - problem with "sed" and
end-of-lines.  I get sources from cvs using cvsnt, which writes CRLF
instead of LF.  And there's an easy way to fix this problem - you can
change
 sed -n -e 's|.*/\* \("[A-Za-z_]*"\) \*/$$|  \1;|p' byterun/fail.h | \
to
 sed -n -e 's|.*/\* \("[A-Za-z_]*"\) \*/|  \1;|p' byterun/fail.h | \
in Makefile.nt (thus not matching end-of-line) - the result will be the
same, but it will work with CRLFs (matching ".?$" or "\r?$" or "\x0D?$"
instead of "$" won't work).
