[Expectperl-discuss] re: building Expect.pm on solaris 9

[Zhisong J. <jj...@dy...>]

I'm trying to build a Expect.pm on solaris 9

1. download expect-1.15 and IO-tty-1.02 source from sourceforge
2. compile and install IO-tty , all OK, \
2. compile expect-1.15,  failed at make test 
$ perl Makefile.pl 
$ make 
$ make test 

"make test failed" , complain about 

Use of uninitialized value in ioctl at
/usr/local/lib/perl5/site_perl/5.8.4/sun4-solaris-thread-multi-64/IO/Pty.pm line 119.
warning: TIOCSCTTY failed, slave might not be set as controlling
terminal: Invalid argument at
/usr/local/lib/perl5/site_perl/5.8.4/sun4-solaris-thread-multi-64/IO/Pty.pm line 120.
TIMEOUT

looking into the source on Pty.pm , the relevent portion is:  
# Acquire a controlling terminal if this doesn't happen automatically
  if (defined TIOCSCTTY) {
    if (not defined ioctl( ${*$self}{'io_pty_slave'}, TIOCSCTTY, 0 )) {
      warn "warning: TIOCSCTTY failed, slave might not be set as
controlling
terminal: $!" if $^W;
    }
  } elsif (defined TCSETCTTY) {
    if (not defined ioctl( ${*$self}{'io_pty_slave'}, TCSETCTTY, 0 )) {
      warn "warning: TCSETCTTY failed, slave might not be set as
controlling
terminal: $!" if $^W;
    }
  }

can somebody suggest a work around or is there exist a solution? 
thanks.
