RE: Building Insight snapshot on CygWin?

["Kevin Powell" <KPowell at sirf dot com>]

Hi -- I'm not on this list, but I have recently compiled insight for Cygwin using the 20030621 snapshot.

FWIW, here are my results:

First -- I got the same message as Gordon Shumacher when building dejagnu:

configure: error: source directory already configured; run make distclean
there first
configure: error:
/usr/src/insight+dejagnu-20030520/dejagnu/example/calc/configure failed for
example/calc
make: *** [configure-dejagnu] Error 1

re-running make seemed to make this go away.

Second, I had problems with expect.  the expect configure script was not picking up the tcl and tk configurations properly, so I had to manually configure expect with --with-tk-config and --with-tcl-config, then I was able to get past building expect.

The rest of the main build went pretty smoothly.

make check fails thusly:

make[6]: Entering directory `/usr/src/insight/insight/dejagnu/testsuite/libdejagnu'
c++ -DPACKAGE=\"dejagnu\" -DVERSION=\"1.4.2\"  -I. -I../../../../insight+dejagnu-20030621/dejagnu/testsuite/libdejagnu      -g -O2 -c ../../../../insight+dejagnu-20030621/dejagnu/testsuite/libdejagnu/unit.cc

Having read that dejagnu was probably broken for cygwin, I didn't bother to try to fix this. Perhaps that was a bad idea, because my newly built insight cannot debug my program.  It crashes as soon as I try to run the target program.  I'll attach the stackdump, though I think it won't be helpful.  I tried to use the cygwin dumper utility to get a core file and use that to further isolate the problem (can one use gdb to debug gdb?), but that failed as well (dumper core dumped before generating the core file).
here's what gdb self reports:

Here's the stackdump:

If there is some obvious bit of information that explains all this (eg, the snapshot I used is known to be busted), please let me know.

Anyway, I've fallen back on using the distributed binary version of insight for cygwin.  I have noted that the binary package gives this self-report

$ /usr/bin/gdb -v

I guess that to build my own, I need whatever makes the standard GDB into a cygwin-special gdb.
