Re: Compiling on 8.1.3 on Openserver 5.05

Thx Tom

I edited the /usr/include/arpa/inet.h and added the following : #include <sys/byteorder.h>

Looks correct as some of the errors seem to be gone, however where would I have to add/include the "h_errno" and the "warning: unreachable code at beginning of switch statement" worries me

gmake command as follows:

ksh# gmake
gmake -C doc all
gmake[1]: Entering directory `/tmp/mdc_postgres8.1.3/postgresql-8.1.3/doc'
gmake[1]: Nothing to be done for `all'.
gmake[1]: Leaving directory `/tmp/mdc_postgres8.1.3/postgresql-8.1.3/doc'

I found the following:
    

u_long ntohl __P((u_long)), htonl __P((u_long));
u_short ntohs __P((u_short)), htons __P((u_short));
#define htonl(x)        (x)
#define ntohs(x)        (x)
#define htons(x)        (x)
in /usr/include/sys/byteorder.h
    

Hmm ... you could add "#include <sys/byteorder.h>" but I fear you're
going to need that in a lot of places.  The Single Unix Spec specifies
that these functions are to be declared in <arpa/inet.h>, and that
seems to be where most systems put 'em, because I can't recall having
heard many previous complaints about this sort of failure.  The shortest
route to success might be to modify your local copy of 
/usr/include/arpa/inet.h to include sys/byteorder.h, instead.

BTW, it could be that arpa/inet.h already does include sys/byteorder.h,
but only when some configuration symbol is defined.  In that case you
might want to force the configuration symbol instead.  Compare HPUX,
where we do
	CPPFLAGS="-D_XOPEN_SOURCE_EXTENDED"
in order to get access to a reasonable set of predefined symbols ...
