So SVR4 was not defined. So it must have tried open()ing /dev/ptyc0 - /dev/ptyc7 which apparently failed. :-) ls -al /dev | grep pty :-) I would expect it to use getpt() instead, which i tested here, and gives me /dev/pty/2 : :-) cd /my/test/c :-) getpty got fd=3 ptsname=/dev/pts/2= crw--w---- 1 root tty 136, 2 Dec 24 18:23 /dev/pts/2 isnotastream parent: got 19 : CHILD sending pty child: got 27 : PARENT: responding on pty :-) The only explanation for that it does work on your systems would be that you do have /dev/pty?? devices. I don't know where these are supposed to be created. POSSIBLY OFFTOPIC: /dev/pts/* are created on the fly by getpt() Also, to see whether the pty gotten with getpt() is a stream, (not necessary, apparently, but more portable) stropts.h needs to be included, which is only included if SVR4 is defined. If it were possible to define SVR4 in the build, it might also solve the other bug. I have no idea how recent SysV Release 4 is (though 'streams' sounds kinda recent), and whether Debian's xxgdb is compatible with it. unreproducible-- ; moreinfo++ ; have fun !
