Compile a module

[Brian Keenan]

Hi,
I'm trying to compile a module using the command
make install && make restart
It errors out with message:
ld: No $UNWIND_END$ subspace has been defined (probably missing /usr/ccs/lib/crt0.o)
apxs:Break: Command failed with rc=65536
*** Error exit code 1

The file /usr/ccs/lib/crt0.o does exist.

Any clues?

regards

Brian

[H.Merijn Brand (procura]

what module?
what C compiler?
what OS?

[Bill McNAMARA_1]

does /usr/ccs/lib/ exist?

swlist | more

To compile a kernel module, you'd use config (1m) and kminstall, but I don't think this is what you're doing..

See also http://www.hp.com/go/developer for general developer support..

Hi

From the 11.00 release notes

These symbols are no longer defined in a PA64 crt0.o:

$RECOVER_END$
$RECOVER_START$
$START$
$UNWIND_END$
$UNWIND_START$
$global$
__argc_value
__argv_value
_start


See www.docs.hp.com

Bill, /usr/ccs/lib exists, because the file /usr/ccs/lib/crt0.o exists (from initial message)

Steve, 64bit builds are not supported from the braindead bundled compiler.

/opt/langtools/lib/crt0.o
/opt/langtools/lib/pa20_64/crt0.o

are the one's used by HP's ANSI-C compiler

[Brian Keenan]

Hi,

swlist file attached.
module is nltm_auth for apache/unix

[H.Merijn Brand (procura]

OS = 11.00

Compiler = HP C-ANSI-C (I hope you *are* using it)
-- your version is B.11.01.07, consider an upgrade:

a5:/ 101 # swlist | grep ANSI
B3901BA B.11.02.04 HP C/ANSI C Developer's Bundle for HP-UX 11.00 (S800)
PHSS_25985 1.0 ANSI C compiler General patch
a5:/ 102 #

Module for Apache. Show us more output from the make. Do you *need* 64bit compile?

[Sean OB_1]

Have you run the .configure that most modules come with?

Then I'm assuming you ran make with no problems. Try "make test" to see if that is in there as an option.

Make sure that /usr/ccs/lib is in your path as well.

OK, this /does/ help. You are feeding your HP C-ANSI-C compiler gcc options. You have two choices

1. Download a working gcc, preferably the same mod_perl was built with, and use that (recent versions can be fetched from https://www.beepz.com/personal/merijn )

2. `Fix' the Makefile to pass correct arguments

-Wc,-Wall => remove, or use +w1
-xildoff => ?
-KPIC => +Z
-Wall => remove, or use +w1

[Brian Keenan]

Hi,

I went for option 2, but still getting the same error.

regards

Brian

[H.Merijn Brand (procura]

The /same/? *Exactly* the same? I don't believe. Show the output again please. (not the missing symbols, I beleive those :)

[Olav Baadsvik]

Hi,

I advise you to modify your makefile so that
it invokes cc to do the link (instaed of
ld as I assume you are using now)

In this way cc will invoke ld and automatically link in /usr/ccs/lib/crt0.o
It will also link in libc. Most of the
uresolved symbols (if not all) are found
in libc

Regards
Olav

Brian,

Make sure that you did a "make clean" after modifying the Makefile. Then "make", and then "make test".

Then let us see the results from the "make test".

[H.Merijn Brand (procura]

can we see 'apxs' please?

the suggestion to replace 'ld' with 'cc' is good, but we're not in that stage (yet). We first have to resolve the fact that cc is passed the wrong options

[Brian Keenan]

Hi,

Attached apxs file

Hey, great! That's a perl script!

Check and see how this works:

my $CFG_CFLAGS = q(-DSOLARIS2=260 -DMOD_SSL=206104 -DMOD_PERL -DUSE_PERL_SSI -I/include -DEAPI -DUSE_EXPAT -I../lib/expat-lite `../apaci`); # substituted via Makefile.tmpl

my $CFG_SYSCONFDIR = q(/apps/9ias/oracle/product/9iAS/Apache/Apache/conf); # substituted via APACI install

Or modify Makefile.tmpl

Since I cannot test above, I can give no guarantee :)

Hi,

That's an exit code of cc?

Calc > 65536

It's causing apxc to exit. To see what happens if you just ignore it, do change

sub execute_cmds {
my (@cmds) = @_;
my ($cmd, $rc);
foreach $cmd (@cmds) {
print STDERR "$cmd\n";
$rc = system("$cmd");
if ($rc != 0) {
printf(STDERR "apxs:Break: Command failed with rc=%d\n", $rc << 8);
exit(1);
}
}
}

to

sub execute_cmds {
my (@cmds) = @_;
my ($cmd, $rc);
foreach $cmd (@cmds) {
print STDERR "$cmd\n";
$rc = system("$cmd");
if ($rc != 0) {
printf(STDERR "apxs:Break: Command failed with rc=%d\n", $rc << 8);
# exit(1);
}
}
}

The error you see does not ring a bell here. I hope someone else can help you out there ...

Sorry, my help ends here. I can't see what causes mod_ntlm.o to be unable to build. Normally the error message you get only indicate a warning, but here they seem to be fatal for cc.

show the code from line 490..495 in mod_ntlm.c maybe someone recognizes the problem

[Brian Keenan]

Hi,

Code lines 489..496
