Hi,
Okay, I did bit more digging and discovered that 'getopt' is also contained in libmingwex.a. GCC - in the mingw version that I have - links this library by default (see the output of gcc -dumpspecs).

$ nm c:/MinGW/lib/libiberty.a | grep getopt
getopt.o:
00000008 D ___getopt_initialized
00000130 t __getopt_initialize
000003f0 T __getopt_internal
00000f20 T _getopt
getopt1.o:
U __getopt_internal
00000000 T _getopt_long
00000030 T _getopt_long_only

I have also two libmingwex.a
$ nm c:/MinGW/lib/libmingwex.a | grep getopt
(none)

$ nm c:/cygwin/lib/mingw/libmingwex.a | grep getopt
getopt.o:
00000670 T _getopt
00000070 t _getopt_internal
000007d0 T _getopt_long

I know that I had to link libiberty.a explicitly when I first compiled Icarus on Windows. You might try that...
How do I do that? In the g++ -o step below I added (modified as)
g++ -Lc:/MinGW/lib/libiberty.a -o ivl.exe main.o ....

but it still gives the same errors:
main.o: In function `Z17read_iconfig_filePKc':
c:/ivl/v81/main.cc:406: undefined reference to `optarg'
main.o: In function `main':
c:/ivl/v81/main.cc:492: undefined reference to `getopt'

lexor.o: In function `Z14VL_init_bufferP15yy_buffer_stateP6_iobuf':
c:/ivl/v81/lexor.cc:2409: undefined reference to `isatty(int)'

Same result if add the other lib -Lc:/cygwin/lib/mingw/libmingwex.a instead.

Do I need to change the compile step too any way? Exactly what is the change needed?

With respect to gperf and bison, I assume Cygwin is providing appropriate versions. If everything compiles okay, then the versions are probably appropriate.

The last step of my instructions is necessary on Mingw because man and ps2pdf are not provided by Mingw.

D. This may not be my immedate problem; but I am not clear about your last step... am I supposed to create those two files each with just those 3 lines? Do I simply create these two files man and ps2pdf and add the three lines you gave? Where should I place these two new files?

Try modifying the Makefile for ivl.exe to link in libiberty. If libmingwex exists in your install, try linking this (you can run 'nm' on the lib first to see if getopt exists in that libmingwex).

Let me know what you find...

Regards,
Matthew

Chacko

Thank you for the response! This is very encouraging that you have had success recently. I was getting a bit desparate :) Even though I have been programming for the last 40 years or so, I am very new to cygwin, ivl, and openSrc in general ... [I had no problem compiling ivl under linux.]

A. My cygwin setup shows gperf 2.7.2-1 as the latest... Is 3.0.1 needed? How come my cygwin installer does not show any past 2.7.2?

B. Bison installed shows 20030307-1.

C. I do have libiberty.a in c:\MinGW\lib (as well as in c:\cygwin\lib); but there is no getopt.h under the MinGW tree, there is one under c:\cygwin\usr\include\mingw. How does the g++ -o step below get to this lib, I do not see any CPP or LD FLAGS referring to this.

D. This may not be my immedate problem; but I am not clear about your last step... am I supposed to create those two files each with just those 3 lines? I do have a c:\cygwin\bin\ps2pdf:
----
#!/bin/sh
# $Id: ps2pdf,v 1.3 2002/02/21 21:49:28 giles Exp $
# Convert PostScript to PDF.

# Currently, we produce PDF 1.2 by default, but this is not guaranteed
# not to change in the future.
exec ps2pdf12 "$@"

and a c:\cygwin\etc\preremove\masn.sh:
----
#!/bin/sh
# man version 1.5p

manifest=/etc/preremove/man-manifest.lst

[ -f $manifest ] || (echo "Unable to find manifest file" && exit 0)

echo "*** Removing unmodified base files."
echo "*** These will be updated by the postinstall script."
echo "*** Please wait."

while read f; do
/bin/cmp -s "/${f}" "/etc/defaults/${f}" && \
(echo /$f hasn\'t been modified, it will be updated ; \
/bin/rm -f "/${f}")
done < ${manifest}

Any help will be very much appreciated!!

getopt comes from libiberty.a - at least on Mingw. Here are my directions for building IVI under Mingw (I use Mingw instead of Cygwin).

- install gperf-3.0.1 (from your favorite GNU mirror)

- install bison-2.0-MSYS from the mingw site

- Create 'man' and 'ps2pdf' shell scripts. Each of these scripts is:
#!/bin/sh

echo ""

Seems to build for me...

Matthew

Any idea where the getopt library comes from for the mingw compile? I have looked everywhere, and have installed more of the cygwin related libs and other stuff without any success. If I know where the lib is located, I may be able to tune the config or Makefile

Do you know of anybody who currently builds the win version? Perhaps I can try to contact him/her?

CLUE: in the first of two steps of ivl.exe build steps,

since there are no additional lib directives, I assume g++ has some libs it searches by default? Do you know which one it might be?
