I'm trying to port some fairly tame programs we've developed here, and
keep running into a include file syntax errors! There's more than
one; /usr/include/utmp.h springs to mind, but I seen to recall file.h
having problems also.
This happens under both cc and gcc; even happens if I do a simple:
#include <utmp.h>
main () {}
type of program. Is this global, is there a fix, or is my computer
hating me this week? :(
Hm.. if it matters, the A/UX dist. was off tape...

Let's take a look at what happens when I try to compile the sample program you posted: 21 servalan /tmp[6:43pm] % cat >foo.c #include <utmp.h> main() {} 22 servalan /tmp[6:43pm] % gcc foo.c In file included from foo.c:1: /usr/include/utmp.h:40: parse error before `time_t' Looking at utmp.h, one notes that the file uses a typedef'd type, time_t, but does not have the definition for time_t. The definition for that, along with a lot of other special types, is found in /usr/include/sys/types.h. Thus one should #include <sys/types.h> before #include-ing <utmp.h>, viz.: 26 servalan /tmp[6:49pm] % cat >foo.c #include <sys/types.h> #include <utmp.h> main() {} 27 servalan /tmp[6:50pm] % gcc foo.c 28 servalan /tmp[6:50pm] % Look, Ma, no errors. -- Richard Todd rmtodd@uokmax.ecn.uoknor.edu rmtodd@chinet.chi.il.us rmtodd@servalan.uucp Motorola Skates On Intel's Head!

It is not terribly unusual (although it can be terribly frustrating) for include files to have dependencies on other include files. In the particular case you gave (utmp.h), you must include <sys/types.h> before including the utmp library. BTW: I did a "man utmp", which brought up the getut(3C) man page, which gives this information. >Chan Wilson Chief Hard-Question Answer Person >SRI Intl.
