I am having a similar problem; here's the Perl script
#!/usr/bin/perl -w
if (-t STDIN) {
print "STDIN OK\n";
} else {
print "no STDIN?\n";
}
if (-t STDOUT) {
print "STDOUT OK\n";
} else {
print "no STDOUT?\n";
}
It results in
no STDIN?
no STDOUT?
Because STDIN and STDOUT do not appear to be attached to a terminal, I cannot run Active State's ppm program. ppm3-bin.bat checks if (-t STDIN and -t STDOUT) and dies if the result is false.
This is Perl 5.8.0, newly installed.
The Problem occurs in both rxvt and the standard console shell.
BASH_VERSION='2.05b.0(1)-release'
CYGWIN='ntsec tty'
Theoretically this is the most recent cygwin version; I did a "reinstall". Not sure what to look at to prove the version #... if there is an environment variable I don't see it.
The folks at ActiveState cannot reproduce this problem; they _can_ run ppm with the latest version of cygwin bash.
Pointers appreciated. What do I need to change, install, uninstall... to cause Perl to believe that STDIN and STDOUT are connected to a terminal?
