On Fedora 16, although environment variable 'TERM' has value 'xterm', xterm isn't
installed. So, when debug scripts which will execute fork(), perl5db.pl will fail
and quit when it executes the following codes, enters line 1493 ~ 1500, because
function xterm_get_fork_TTY need xterm program:
1487 if (not defined &get_fork_TTY)
1488 {
1489 if ( defined $remoteport ) {
1490
1491 *get_fork_TTY = \&socket_get_fork_TTY;
1492 }
1493 elsif (defined $ENV{TERM}
1494
1495 and $ENV{TERM} eq 'xterm'
1496 and defined $ENV{DISPLAY}
1497 )
1498 {
1499 *get_fork_TTY = \&xterm_get_fork_TTY;
1500 }
1501 elsif ( $^O eq 'os2' ) {
1502 *get_fork_TTY = \&os2_get_fork_TTY;
1503 }
1504 elsif ( $^O eq 'darwin'
1505 and defined $ENV{TERM_PROGRAM}
1506 and $ENV{TERM_PROGRAM}
1507 eq 'Apple_Terminal'
1508 )
1509 {
1510 *get_fork_TTY = \&macosx_get_fork_TTY;
1511 }
1512 } ## end if (not defined &get_fork_TTY...
How did you come the idea that TERM environment variable carries terminal emulator executable name? The TERM defines type of terminal. Not a binary. What is `VT100' or `linux'? The current perl debuger code is just an ugly hack which must resolve upstream. Ask Free Desktop project for support in adding portable way how to spawn new terminal (emulator). Good idea. I will. |
