Your g77 failures are caused by linking with -lm.  Try the following patch
to usr/share/dejagnu/target.exp.  Crude, but it works.

I see you managed to get dejagnu running with cygwin installed in c:\cygwin.
I have not been able to do this.   Did you install your own versions of
dejagnu, tcltk and expect.  If so, where did you get them from and how did
you build them?

I believe I had to set DEJAGNULIBS to c:/Cygwin/usr/share/dejagnu and 
*may* have had to set TCL_LIBRARY=c:/Cygwin/usr/share/tcl8.0 before
running `make check'.

  $ export DEJAGNULIBS=c:/Cygwin/usr/share/dejganu
  $ export TCL_LIBRARY=c:/Cygwin/usr/share/tcl8.0
  $ make check

I'll try it again this evening and see if I needed anything more. 

That said, that gets you gcc and g77 tests; for g++, you may run
into a problem in running dg.exp (it looks for "/tests.exp", which
means something is looking for POSIX-style pathnames only). Time
to start looking in Tcl to get the pathnames fixed once and for all
so that it understands Cygwin mounts correctly. 

Christian hopefully has a better way of doing this!

Regards,
Mumit

Why does linking -lm cause problems?  It should have no effect.

The unix version of Tcl build with Cygwin and configured with `gcc -mno-win32'.
As a side effect, Tcl understands Cygwin paths.

Tcl pathname isssues [Re: Results for 2.97 20010115 (experimental) testsuite on i686-pc -cygwin]

Thanks Earnie for reminding me of this! I'll have to try it out and see
what happens.

The current Cygwin Tcl port's trouble with Cygwin paths/mounts is quite
fixable IMO, and it may be a matter of doing the path/name translation 
in a different place than is done right now. I remember trying to fix 
this a *long* time ago, but ran into a Cygwin bug in resolving relative 
symlink; I belive cgf fixed when he bacame an active contributor (like 
I said, it was a long time ago), but I never moved it off the back
burner.

My memory is rather shoddy on what exactly the potential fix was and
wheter it actually fixed the problem or not, but we'll cross that
bridge later.

Regards,
Mumit

A few things have changed in the path recognition since you've been gone so even if
you remember exactly what it is, it is likely not to work the same.  If a path
contains a : in column 2 or contains a \ character it is now determined to be an
absolute windows path.  Chris, is this the correct wording for this feature?

Earnie.

That's not really what I'm referring to. This is quite a few years ago,
and the problem is that we don't use Cygwin's cygwin_conv_to* API to
do the right thing. It may be Tcl_TranslateFileName where it needs to
be done, on top of the current Cygwin code bits there, but that's what
I need to investigate.

Mumit

Thanks for your tips about -lm, I saw that some weeks ago when I raised the
issue of dejagnu with cygwin-1.1.7 and GCC testsuite. I just thought I'd
make
a clean build first.

As you can see in the beginning of my e-mail, I have installed, the test
releases
available with the cygwin setup utility, of dejagnu-20010117-1 and
expect-20010117-1. The rest is "standard" cygwin.

N.B., there are two new tests passing...

Cheers,

/ChJ

Perhaps your patch is "the right thing", then I would like to see it in
cygwin's dejagnu, OTOH, "-lm" is quite normal to have. Perhaps cygwin could
handle "multiple" "-lm"  as "-lcygwin" in principle is "-lm" also...

But, what the heck, I'm, just a user... :-)

Thanks for trying this.  I've been meaning to announce it for a while
but I wanted to check how it worked myself first.

This is just a dejagnu/expect built from sources.redhat.com, which is
what I have been exhorting people to use for a while.

Sorry Chris.  Once you're not "just a user", you can never go back to being
"just a user".  Its just one of those little ironies of life.  Its kind of

I guess I was vainly hoping that someone would actually debug the
problem or offer insight into the reason for the problem rather than
saying "Just remove -lm! Works for me!"

Sorry.  I forgot what group I was sending email to.
