$ cygcheck -c luit Cygwin Package Information Package Version Status luit 1.0.3-1 OK $ /usr/bin/luit.exe Couldn't allocate pty: No such file or directory This error is caused by trying to opening a pseudo terminal in a BSD way (instead of in a SVR4 or Unix-98 way). Here are the relevant parts in sys.c: #if (defined(__GLIBC__) && \ (__GLIBC__ > 2 || (__GLIBC__ == 2 && __GLIBC_MINOR__ >= 1))) || \ defined(SVR4) #define HAVE_GRANTPT #endif ............................... int allocatePty(int *pty_return, char **line_return) { char name[12], *line = NULL; int pty = -1; char *name1 = "pqrstuvwxyzPQRST", *name2 = "0123456789abcdefghijklmnopqrstuv"; ............................... #ifdef HAVE_GRANTPT ................................ pty = open("/dev/ptmx", O_RDWR); ..................................... #endif /* HAVE_GRANTPT */ strcpy(name, "/dev/pty??"); for(p1 = name1; *p1; p1++) { name[8] = *p1; for(p2 = name2; *p2; p2++) { name[9] = *p2; pty = open(name, O_RDWR); In cygwin, the absense of __GLIBC__ or SVR4 causes HAVE_GRANTPT to be undefined, and so the codes to use SVR4 (or Unix-98) pseudo terminals are not enabled. A simple fix is to add "|| defined(__CYGWIN__)", but the recent master of luit has a better fix. It replaced "#if (defined(__GLIBC__) && ..." with a real configure test for grantpt. http://cgit.freedesktop.org/xorg/app/luit/commit/?h=4823838f77ab03cccd07860fdf8002bc577e0f04 -------------------------------------- Power up the Internet with Yahoo!
