| 153 | environment, see <http://sources.redhat.com/cygwin/>. | |
| 154 | .PP | |
| 155 | Please note that pty creation is very system\-dependend. From my | |
| 156 | experience, any modern \s-1POSIX\s0 system should be fine. Find below a list | |
| 157 | of systems that \f(CW\*(C`IO::Tty\*(C'\fR should work on. A more detailed table is | |

| 161 | If you have problems on your system and your system is listed in the | |
| 162 | \&\*(L"verified\*(R" list, you probably have some non-standard setup, e.g. you | |
| 163 | compiled your Linux-kernel yourself and disabled ptys (bummer!). | |
| 164 | Please ask your friendly sysadmin for help. | |
| 165 | .PP | |
| 166 | If your system is not listed, unpack the latest version of \f(CW\*(C`IO::Tty\*(C'\fR, | |
| 167 | do a \f(CW'perl Makefile.PL; make; make test; uname \-a'\fR and send me | |
| 168 | (\fIRGiersig@cpan.org\fR) the results and I'll see what I can deduce from | |
| 169 | that. There are chances that it will work right out\-of\-the\-box... | |
| 170 | .PP | |
| 171 | If it's working on your system, please send me a short note with | |
| 172 | details (version number, distribution, etc. \f(CW'uname \-a'\fR is a good | |
| 173 | start) so I can get an overview. Thanks! | |
