HP-UX support

[Tontonitch]

Hi,
This project looks very nice!
It would be great to see it working on HP-UX platforms.
I tried to compile it (even if the platform is not supported), but it stop at
checking if host OS is supported... no
configure: error: *** unsupported OS hpux11.31
Every other checks are ok.
Best regards,
Yannick

Maybe that's not very hard to add support for HPUX, maybe not. You can
modify m4/os.m4, then run ./autogen.sh (if it fails in HPUX, just do it
on a recent Linux, then sync the directory). If I can get a shell
access, it would help. Or maybe this is something that could run in a

virtual machine?

Make sure your code "does nothing" gracefully.

Hi Vincent,
With the change (the change has been done on another node (CentOS)), the ./autogen.sh and then the ./configure produced a small warning (./configure[3365]: AM_PROG_AR: not found.)
But doesn't seem an important/blocking problem.
Then, the configure script ran ok, ended with the following summary:

For your info, I've added the following line to m4/os.m4:

Try grep AF_LOCAL /usr/include -r. Maybe we need to include some other

file. Otherwise, just replace AF_LOCAL by AF_UNIX.

Use data arrays to avoid repetitive control sequences.

(you've hit critical mass when people go for HP-UX support)

[Tontonitch]

I've replaced AF_LOCAL by AF_UNIX in priv.c, the compilation went a step ahead, but some other compilation issues. The err.h header file cannot be found apparently. Is it normally part of the sources?

For your information, availability of the err.h file:
On Centos6.5:

[root@srv lldpd-0.7.7]# find /usr/include -name "err.h"
/usr/include/openssl/err.h
/usr/include/err.h
[root@srv lldpd-0.7.7]# find /usr/include -name "errno.h"
/usr/include/asm/errno.h
/usr/include/sys/errno.h
/usr/include/asm-generic/errno.h
/usr/include/bits/errno.h
/usr/include/errno.h
/usr/include/linux/errno.h
[root@srv lldpd-0.7.7]#

On HPUX11.31

root@hpsrv# find /usr/include -name "err.h"
root@hpsrv# find /usr/include -name "errno.h"
/usr/include/aCC/errno.h
/usr/include/aCC_std/errno.h
/usr/include/errno.h
/usr/include/sys/errno.h
root@hpsrv#

So, no err.h on hpux.

Best regards,
Yannick

[vincentbernat]

You can remove the #include <err.h>, it is a legacy header that is not needed any more.

[Tontonitch]

Thank for the info. err.h removed.

So the compilation still stops here:

I tried some code changes, but my c skills are too light... So I couldn't fix the problem.
If I can test some changes, please ask.
Best regards,

[vincentbernat]

I had the same problem with Solaris. Could you grep in /usr/include for cmsghdr to check that this feature is supported on HP-UX (but I think it is). Do you have cmsg(3) as a manual page? Maybe they would say how to get them. Otherwise, could you add at the top of the file:

#define _XOPEN_SOURCE 1
#define _XOPEN_SOURCE_EXTENDED 1

[Tontonitch]

Indeed, I would say it is supported:

root@hpora2-b# grep cmsghdr /usr/include/*
root@hpora2-b# grep cmsghdr /usr/include/sys/*
/usr/include/sys/socket.h: * Given a byte length, align it to word boundary, aligned for cmsghdr.
/usr/include/sys/socket.h: * of message elements headed by cmsghdr structures.
/usr/include/sys/socket.h:struct cmsghdr {
/usr/include/sys/socket.h:/* given pointer to struct cmsghdr, return pointer to data */
/usr/include/sys/socket.h:                      _CMSG_ALIGN(sizeof(struct cmsghdr))))
/usr/include/sys/socket.h:/* given pointer to struct msghdr, return pointer to first cmsghdr */
/usr/include/sys/socket.h:      ((mhdr)->msg_controllen >= sizeof(struct cmsghdr) ?     \
/usr/include/sys/socket.h:        (struct cmsghdr *)(mhdr)->msg_control :               \
/usr/include/sys/socket.h:/* given pointer to struct cmsghdr, return pointer to next cmsghdr */

No manual entry:

I added the 2 variable definitions, the compilation went further, but returned finally the following errors:

PS: I will be unavailable until next monday

[vincentbernat]

OK, now comes the hard part. :)

You need to modify src/daemon/Makefile.am. Look at the block HOST_OS_NETBSD. I think this is the one that has a better chance to work for you. Duplicate it for HPUX and let's what works. You need to run ./autogen.sh again.

For other problems:

• missing asprintf() and vasprintf(), there is a fix for that in the git HEAD
• missing vsyslog(), well I don't know how to build this from syslog(), let me think about it
• missing daemon(), I will reimplement it

[vincentbernat]

Never mind for vsyslog(), this is easy to build it from vasprintf().

[vincentbernat]

The "other" problems should be fixed in git HEAD.

[Tontonitch]

Hi Vincent,
I took the last git master HEAD, commit 984bbcb.
Adapted the sources with your previous directives, when needed, to add HP-UX.

For the first error, it is a late change that I didn't test. The second one should also be solved by including a missing header (stdarg.h). Please try again.

However, keep in mind that's the "easy" part. The remaining part (network stuff) will be far harder except if HP-UX behaves exactly like one of the existing BSD. A (non-root) shell would help.
