Problem building Ruby from sources

Hello,

I am having a problem building Ruby from sources (checked out latest
version with Subversion from repository). I tried it for Ubunty 8.04 and
Cygwin. In both cases I got an error while running make:

echo executable host ruby is required. use --with-baseruby option.;
false -Ks ./tool/insns2vm.rb --srcdir="." opt_sc.inc
executable host ruby is required. use --with-baseruby option.
make: *** [opt_sc.inc] Error 1

What does it mean?

Thank you,

Kurt

You don't have ruby installed, or it is not in your path.

If it is not in your path, use ./configure --with-baseruby (I think).

If it is not installed, try 1.8 before building 1.9.

Does it now need a running Ruby interpreter to build?

I tried to install 1.8 (and tested that it is working) before build
(although it seemed to me strange enough not to be able to build Ruby
from scratch) and configure --with-baseruby with approximately the same
result...

1) you can check the recv msg if msg==nil
2) maybe the send msg must add "\0" at end

Hello all,

I'm trying to get acquainted with network programming in Ruby and I'm
facing several problems. The biggest 2 are

1) How do I detect a connection loss when it happens while the client is
blocking, waiting for data? According to Stevens, most tcp
implementations time out after 11 minutes, but I disconnected my cable
and waited long after that--nothing. Is this my fault? Is it a ruby
problem?

2) The client (an IRC bot) seems to be stuck sometimes. Suddenly, input
stops, it stops logging data, everything stops. This happens on a
particular IRC server (heinlein.freenode.net) in the middle of the MOTD,
but happened a few days ago on another server during normal usage. The
code I'm using is

  buffer = @socket.recvfrom(512).first
  messages = buffer.split /\n/

  @messages.last << messages.shift \
    if @messages.last && @messages.last[-1] != ?\r

  @messages += messages

An interesting twist is that this doesn't happen on heinlein upon
connection if I print the contents of the array I get from recvfrom.
Seems to be some kind of flushing problem, but I don't know enough about
it to be sure.

Any ideas?

Cheers,

David
