Building with cygwin

Mon Jan 11 16:00:57 UTC 2010

>From what I have determined the make that works with CYGWIN requires the run time libraries CYGINTL-3.DLL and CYGWIN1.DLL.  These appear to be the C runtime libraries.  There is nothing in the build instructions for GNU MAKE that suggests how to build with these, in particular which compiler and linker are required.  The CYGWIN files I've downloaded only include .a files, not .lib files, so I presume GCC is required rather than MSVC.

I've narrowed it down to make.  There is definitely something different about the make.exe that I downloaded from your link, http://cr.openjdk.java.net/~ohair/MakeBinaries/cygwin-windows-i586/ and the one I'm trying to build from GNU Make source.  I did a simple sanity test from the base OpenJDK source and your make.exe works, but mine does not.  So I guess I now need instructions on how to build make.exe correctly.

I've built gnu make for both 3.80 and 3.81 with these defined in config.h.W32:
HAVE_DOS_PATHS
HAVE_CYGWIN_SHELL

I've previously run using MKS with 3.80 with HAVE_MKS_SHELL instead of HAVE_CYGWIN_SHELL and had no problems.

I've downloaded executable forms of cygwin, but I built my own gnu make.  I don't use the make that comes with cygwin.  The gnu make build doesn't have any compile-time dependency on cygwin.  The make.exe you referenced requires a cygwin dll.  I'm not sure what all this means.

Don;t know what to say on that. I haven't actually built make on cygwin.
I did build it for Linux. Solaris, and MKS, but not cygwin.

If it built with MKS, I'd be puzzled as to why cygwin would be a problem.

Yup.

The issue with 3.81 on Windows was that the one provided in cygwin did not accept
the drive letter paths, e.g. C:/path, and we need that. As far as I know it's the
way the make is built that allows for C:/ paths.
As long as you have a 3.81 that accepts C:/, 3.81 is fine.

However, what I found out was that 3.81 has some problems with MKS and quoting.
These jdk changes: http://hg.openjdk.java.net/jdk7/jdk7/jdk/rev/bf6b160b455d
was essentially a workaround for MKS and make 3.81 on Windows.
The openjdk7 makefiles will soon be requiring GNU make 3.81.

The alternative was what was described in the README.W32 file of the source
distribution, I found this online copy:
   http://www.opensource.apple.com/source/gnumake/gnumake-119/make/README.W32
See the section on BATCH_MODE_ONLY_SHELL.

Haven't seen any issues with 1.7 cygwin, but haven't used it much either.

Again, I have not seen any issues with using the cygwin make 3.81 from
  http://www.cmake.org/files/cygwin/make.exe

I get the feeling that cygwin 1.7 requires a recompile, I see that there
is a cygwin 1.7 version at:
   http://www.cmake.org/files/cygwin/make.exe-cygwin1.7

I'll try and find out the formula for building GNU make 3.81 on cygwin
so that it accepts c:/ paths and let you know.
