Hi

I'm using picolisp on Windows(cygwin).

I'm trying to run family.l (located at /doc) as explained (pil family.l
-main -go +)

but I got this error:

"DB read: Bad file descriptor" and localhost 8080 is waiting.

Can someone who (uses cygwin) to solve this problem.

Thanks

ly

I don't have cygwin here, but I assume that you can install 'strace'. If
so, could you do the following?

   1. Find out the process ID of the process causing this error _before_
      the error happens.

   2. Start 'strace' with a redirection of the standard error

      $ strace -p <pid> 2>strace.out

   3. Proceed with the application to produce the error.

Then post the file "strace.out" here. Perhaps we can get a hint about
the reason.

Cheers,
