python2.0 and redhat 7.0 (new issue)

[D-Man]

Ok,  I tried that with the following results:

$ find / -name "*.h" -exec grep forkpty {} \; -print 2>/dev/nullextern int forkpty (int *__amaster, char *__name,
/usr/include/pty.h
pid_t  	      vt_forkpty        (struct vt_em *vt, int do_uwtmp_log);
/usr/include/zvt/vt.h
int	     zvt_term_forkpty		       (ZvtTerm *term, int do_uwtmp_log);
/usr/include/zvt/zvtterm.h
/* Define if you have the forkpty function.  */
/usr/include/python2.0/config.h
/* BSDI does not supply a prototype for the 'openpty' and 'forkpty'
extern int forkpty(int *, char *, struct termios *, struct winsize *);
/usr/include/python2.0/pyport.h


So the protoype exists.  Since glimmer compiled without any problems, I expected that.  The real issue was finding the definition of the functions in a library file.

(in /usr/lib)
$ nm * -l 2>/dev/null | grep -E "(openpty|forkpty)"

If I'm reading this right, the functions openpty and forkpty came from the source files openpty.c and forkpty.c respectively and were compiled into the files openpty.o and forkpty.o respectively.  Then I tried this:

(in /usr/lib)
$ grep -E "(openpty|forkpty)" * 2>/dev/null
Binary file libutil.a matches
Binary file libutil.so matches
Binary file libwine.so matches
Binary file libwine.so.1.0 matches
Binary file libzvt.a matches
Binary file libzvt.so matches
Binary file libzvt.so.2 matches
Binary file libzvt.so.2.2.9 matches

(in /lib)
$ grep -E "(openpty|forkpty)" * 2>/dev/null
Binary file libutil-2.1.94.so matches
Binary file libutil.so.1 matches


Would the function glimmer wants be in the libutil file?

Thanks,

 | The following commands and variants are your friends:

 | find / -name "*.h" -exec grep forkpty {} \; -print
