[Caml-list] unable to install opam under cywgin

[David Guaspari]

I am trying to install opam 1.1.2.  Under cygwin I do

  ./configure
  make lib-ext
  make
  make install

The last of these fails with the error message

-- begin

OPAMROOT=/tmp/opam-install-install src/opam-installer --prefix /usr/local
opam.install
[ERROR] Could not find "C:\\opam-full-1.1.2\\src\\opam"
[ERROR] Could not find "C:\\opam-full-1.1.2\\src\\opam-admin"
[ERROR] Could not find "C:\\opam-full-1.1.2\\src\\opam-installer"
doc/man\opam.1                   => /usr/local\man\man1\opam.1
Fatal error: exception Unix.Unix_error(20, "create_process", "/bin/sh")
Makefile:52: recipe for target 'install' failed
make: *** [install] Error 2

-- end

In fact, the directory C:opam-full-1.1.2\src contains the executables
    opam.exe
    opam-admin.exe
    opam-installer.exe

I made copies of these named  opam, opam-admin, opam-installer and
reran

    make install.

Now the error message is shorter

-- begin

OPAMROOT=/tmp/opam-install-install src/opam-installer --prefix /usr/local
opam.install
src\opam                         => /usr/local\bin\opam
Fatal error: exception Unix.Unix_error(20, "create_process", "/bin/sh")
Makefile:52: recipe for target 'install' failed
make: *** [install] Error 2

 -- end

Here's a guess. The installation wants to execute files whose names do not
end
in ".exe", but create_process (on a Windows machine) fails because it
wants a file whose
name ends in ".exe". If my guess is right, I'm not sure how to fix the
problem.

Any help would be appreciated.

===> Error 20 is Unix.ENOENT, which means "No such file or directory".
That means it can't find "/bin/sh". Are you sure that you have
"/bin/sh"?

If the program is "native windows", it cannot understand posix paths
like /bin/sh. It is a very likely issue in this context.

On Windows, you can ask to run either "foo" or "foo.exe" and you get the
same behaviour (well, iirc: you'd have to check the doc for
CreateProcess to be sure).
