This is indeed a mystery to me. Perhaps the people working
with cygwin and related matters, such as tcl/tk and dejagnu
thereunder, on cygwin list have any comments?

My e-mail to David had this question in it:

-----
Hello David.

I'm just curious, how did you get the testsuite running?

I always get can't find /usr/share/dejagnu/runtest.exp
regardless if I set DEJAGNULIBS as /usr/share/dejagnu or
something like /cygdrive/c/cygwin/usr/share/dejagnu...

Oh, I have a win2k/pro/sp1 with an up to date cygwin-1.1.7.

Cheers,

/ChJ
-----

and it was because of his "report" to the gcc-testresults list

http://gcc.gnu.org/ml/gcc-testresults/2000-12/msg00326.html

I'm quite interested in hearing about how to get dejagnu/tcl
working more "properly" under cygwin, i.e., I can have cygwin
installed wherever I want to, like the recommended C:\cygwin,
and still be able to run the GCC testsuite.

TIA for any comments.

tcl is not a cygwin application so tcl+dejagnu don't understand
cygwin mounts.

However, the unix version of tcl will build with Cygwin and therefore understand
Cygwin's mounts.  You can also build the unix version of tk but that requires the
X11 from cygwin-xfree.

Yep. DJ actually got a version of dejagnu/tcl working some time ago but we haven't
had the cycles to make a release.  It's possible that the dejagnu + tcl + winsup
in sources.redhat.com may just build and work though, if anyone wants to give it
a shot.

If anyone does try, remember to `CC='gcc -mno-win32'' first.

     Hi there,

  I'm also using cygwin on win2k, without any service packs. I hadn't
heard the advice that dejagnu needs your cygwin installation to be in the
root of a drive, so I haven't followed it, but I've managed to get dejagnu
working on my system. The two things that seemed to make all the
difference in my case were:
   -  I had several futile attempts to build and install dejagnu using
tarballs I found on ftp.gnu.org and cygwin mirror sites. None of these
even built correctly. What finally worked for me was getting the CVS
sources from the cygwin anon cvs server (which is also the gcc server).
   -  I don't know how it happened, but I found that I had both tcl8.0 and
tk8.0 installations existing in both /usr/share and /usr/local/share.
OTOH, my dejagnu installation from the CVS put itself into
/usr/local/share. I don't really know what's going on with that, but
pointing DEJAGNULIBS at /usr/share really wouldn't work for me, because
there's no dejagnu directory there.
   -  Other possibly-relevant facts are that I'm working with the 2.95.3
branch of gcc, and that I'm running cross-compiler tests on a remote
target board.

    Here's the contents of my .bashrc, which I think may be relevant:

---------------------------------------------
export PATH=$PATH:/usr/local/lib
export LD_RUN_PATH=/usr/local/lib
export TCL_LIBRARY=/usr/share/tcl8.0
export DEJAGNULIBS=/usr/local/share/dejagnu
export DEJAGNU=/home/dkadmin/gcc/build/cvs4/gcc/testsuite/site.exp
---------------------------------------------

  The DEJAGNU definition points at the site.exp in my current working
version of the GCC CVS sources. I've attached my cygcheck output as well.
I'm reading this from the Gcc list; apologies for crossposting to cygwin
when I'm not going to see replies on that list, but I thought my
information might be relevant anyway.

     cheers,
        DaveK

I've downloaded dejagnu from sources.redhat.com/pub/dejagnu

What else do i need to load down?
There is a libiberty dir, but no header are included, i tried to use the header from 
cygwin-cvs sources, but make failed.

You need to use the CVS version of dejagnu + the reset of the sources.redhat.com tools.

These fixes are working here, on W2KSP1.  Thanks.  I've run into addtional
problems which are triggered by g77 -O -march=pentiumpro, and I'm still at a
loss how to track them down. The compilers seem fairly stable without the
pentiumpro option. Would someone be interested if I could show a gcc
translation which replicates an ICE, on both linux and cygwin?

This is probably of interest to other cygwin users.  It is for current gcc
cvs.  I'll write up the -lm problem with g77 for the cygwin list, as it also
occurs with the current cygwin release.

Christian.

This is how I did it.  Some of the changes are hacks looking for better
solutions.  cygwin needs to be installed in the root directory of the drive
(C:\ or D:\).  This is against the general advise, but is the only known way
to get dejagnu to work.

----------------------------------------------------------------------------
----------------------------
The g77 execute tests fail as cygwin g77 does not like "-lm".  I removed it
from /usr/share/dejagnu/target.exp.  There is probably a neater way to do
it, but ...

RE: Getting GCC's testsuite, i.e., dejagnu, under cygwin-1.1.7

This is probably of interest to other cygwin users.  It is for current gcc
cvs.  I'll write up the -lm problem with g77 for the cygwin list, as it also
occurs with the current cygwin release.

Christian.

This is how I did it.  Some of the changes are hacks looking for better
solutions.  cygwin needs to be installed in the root directory of the drive
(C:\ or D:\).  This is against the general advise, but is the only known way
to get dejagnu to work.

----------------------------------------------------------------------------
----------------------------
The g77 execute tests fail as cygwin g77 does not like "-lm".  I removed it
from /usr/share/dejagnu/target.exp.  There is probably a neater way to do
it, but ...

The g++ testsuite will not run as dejagnu cannot exec
${odir_v3}/tests_flags.  Fixed thus.  This has been submitted to
gcc-patches.
