Which I've never done; I'm not a cygwin developer, just a user.
Do you remember where cygwin documents how to set up a build environment
and get a build going?

I think you're down to building and debugging the code.

We'll make a developer out of you yet! :-)

You'll need to run setup and install the 'gcc' package (not
gcc2) and the 'gdb' package.  That should install everything
you need as a build environment.  You'll also want the source
for tar.  Get that from setup too.  Once done installing,
do the following:

   1. cd /usr/src/tar-1.13.25-1/
   2. ./configure CFLAGS=-g
   3. make

Now you can try this version to see if your problem reproduces.
The new 'tar' is in ./src.  If you can reproduce the problem there,
try it in gdb.  To do so, type 'gdb src/tar.exe'.  At the gdb prompt,
type 'r <command line parameters that you give to tar to reproduce
the problem>'.  This will start it running.   When you think it's to
the point where it's hanging, type ctrl-c to stop it and then 'bt'.
This will tell you where you are.  You can step through the code with
'n'.  Presumably, you'll see you're cycling through the same statements
at some point.

This may not point out the source of the problem to you, although
you'll have more information to report to the list about the case
you're running into.  The steps you took, things you saw, and the
result of 'bt' (initially at least) may help someone on this list
spot your problem.

Good luck and enjoy! ;-)

Larry

Larry,

Can I just jump in here and say thanks for doing this quick intro to
debugging?

The closest I've come to gcc and gdb was using DJGPP about eight years ago
and it's hard to know where to start when things go wrong. This should get
me started next time something does...

Andrew.

Hmm, I wonder if it would make sense to have an FAQ entry with this info?
I know it's not Cygwin specific, but something like:

   Q: How do I debug something on a Cygwin system?
   A: Same way you do it under any Unix system, i.e., <and the info Larry
      provided below>.

The above would be nice to have to point people at when they need to debug
some application...  Another alternative is to put it in the User's Guide.

It's the checkbox marked "Src" between the version and the name of the

tar 1.13.25 runs forever, consuming CPU time, and produces nothing, on the following
test case:

Go to an empty directory.  Extract the attached with "tar -xzf hang.tgz".
Test that tar works on the extracted tree by doing something like "tar -cf /temp/test.tar ."

Now, "mv ATA_INTERFAC ATA_INTERFACE" and then try the tar again: "tar -cf /temp/test.tar ."
and tar will run forever, consuming CPU time, and leaving /temp/test.tar at 0 bytes.
(At least tar 1.13.25 does, on my Win 2000 box.)
