Hi all,

I'm still trying to build Source Navigator under Windows using VC++ 6.0.
I've gotten to the point of the 'make' where it is trying to build the grep
portion of Source Navigator.  Everything else ahead of grep seems to compile
and link okay.  I notice two problems.

First problem encountered:

  It appeared that a portion of grep compiles.  It then runs into a problem
with a missing libintl.h file.  When I look into the include directory
../intl, sure enough the file is there, but, it is a Windows shortcut file
to libgettext.h back in the source tree.  I wasn't aware that Make would
work with shortcut files.  If I replace the shortcut with a real version of
the file (not libgettext.h), I get past this problem.  Why is this shortcut
file being created for me?  Also, if I use '--with-included-gettext' for
configure, the problem still exists, even though this would suggest
eliminating the need for libintl.h.  Any ideas?

  Making all in src

Second problem encountered: 
 
  After copying a real libintl.h file into ../grep/intl, the make compiles
the c files okay and then tries to work with a file called libintl.a.  I get
the following output.  Could anyone give me a clue as to what is going
wrong?  Is there an incompatability with VC++ compiler/linker?  I tried
adding '--with-included-gettext' to the configure and starting over with a
clean build directory.  No change.

Thanks Mo for looking at this.

I've been using export="cl.exe".  It's only slightly different than what you
suggest.  Do you think it would make a difference?

Groan! I looked in grep/configure.in and found this:

dnl FIXME: this overcomes a flaw in using non-Cygwin tools with symlinks.
if test x$ac_cv_prog_CC = xcl ; then
  AC_MSG_RESULT([copying libgettext.h to intl/libintl.h])
  if test -f $nls_cv_header_intl ; then
    rm $nls_cv_header_intl
  fi
  cp $srcdir/$nls_cv_header_libgt $nls_cv_header_intl
fi

Looks like you need to use export CC=cl to get around that.

This is just a goofy hack in the old grep build system. It should not
cause problems linking.

This is also caused by the CC=cl thing.

From configure.in:

if test x$ac_cv_prog_CC = xcl ; then
  AC_DEFINE(alloca, _alloca)
fi

cheers
