Well, I'm running a variety of AIX platforms. We have 4.3.3 (to be decommissioned soon, honest) one at 5.1, 32-bit and a 6.1, 64 bit. I get the same on all apart from AIX 6.1, so I put it down to user error Smilie

Unfortunately, we don't even have the gcc compiler. We do have the official IBM XLC compiler, version 5 on AIX 5.1 and version 10 on AIX 6.1 yacc appears to be on all of them too, although I've never used it. Come to think of it, I've only used the available C compiler to sompile sudo, lsof and a few other tools. Sorry about that.


So, the errors:
Code:

I feel completely useless on this, but extra depressed because the diskwasher popped last night (overflow/flood detection triggerred), we're snowed in and the wife's parents are with us for a weekSmilie

Any pointers? The place we really want this is on the AIX 5.1 servers, if that concentrates things.

.... on either the shc or dishwasher Smilie

Smilie Aha! I have it working on AIX 6.1 by running Smilie
Code:
shc -T -f robin.ksh

Oh snow, we don't see that much in Australia, especially around christmas time, in-laws - yes heaps, but snow, not so much, lol.

I think if you update the makefile and add the line is blue lines below it should compile with the CC=cc; export CC setting:

Code:
# For GNU C compiler
CFLAGS = -Wall -O6 # -pedantic
 
# For AIX 5.1
CFLAGS = -O3
 
SHELL = /bin/sh

I did try to go a bit wild when I saw the "Undefined symbol". I searched out every direcotry called lib and added it to my LIBPATH (ignoring 3rd party software)

No difference. Smilie

Umm, that's a bit of a concern as atoll() is typically part of the base system (in libc.a). If your system has strtoll() we can use this instead by defining a macro below the definition of SIZE (around line 102) as show in blue:

Code:
#define SIZE 4096
#define atoll(x) strtoll(x, (char **)NULL, 10)

Firstly, good news that your home is not affected by the floods.


That helps a little in that I get a shc executeable, however using it fails. I created a very simple script:-
Code:
#!/bin/ksh
echo "Hello"

and ran the following:-
Code:
$ shc -x my_hello -f robin
shc -x my_hello -f robin
ld: 0711-317 ERROR: Undefined symbol: .atoll
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.
shc: Error 0
$ ls -lrt | tail -5
-rw-r-----   1 RBATTE1  SYSSUP        25009 17 Jan 10:50 shc-3.8.7.c
-rwxr-xr-x   1 RBATTE1  SYSSUP        48454 17 Jan 10:50 shc

-rw-r--r--   1 RBATTE1  SYSSUP         8016 17 Jan 10:53 robin.x.o
-rw-r--r--   1 RBATTE1  SYSSUP         9514 17 Jan 10:53 robin.x.c

I also tried to edit shc.c / shc-3.8.7.c to change the two atoll references in the code to be strtoll (not even sure if this is valid! Smilie) and got the following:
Code:
shc -x my_hello -f robin
"robin.x.c", line 290.32: 1506-098 (E) Missing argument(s).
$ ls -lrt|tail -5
-rw-r--r--   1 RBATTE1  SYSSUP           24 17 Jan 10:53 robin
-rw-r-----   1 RBATTE1  SYSSUP        25013 17 Jan 10:57 shc-3.8.7.c
-rwxr-xr-x   1 RBATTE1  SYSSUP        48454 17 Jan 10:57 shc
-rw-r--r--   1 RBATTE1  SYSSUP         9231 17 Jan 10:57 robin.x.c
-rwx--x--x   1 RBATTE1  SYSSUP         7757 17 Jan 10:57 robin.x

Like a fool, I tried to see what would happen if I ran the file marked as executable:-
Code:
$ robin.x
robin.x: my_hello:  not found.
$

I did find this on an IBM site Using the GNU C/C++ compiler on AIX:-
Quote:
AIX 5.2 added support for the atoll() function, but GCC built for AIX 5.1 includes a cached copy of stdlib.h that does not include the prototype for that function.
Does this mean I've got a dead duck? Smilie We're on a mixture of AIX 5.1Smilie and 4.3.3 Smilie

Nice innings by Mr. Watson over the weekend. Much better these games than the all five one-sided test matches. England were lucky in my opinion not to have lost the first, and that would have changed the whole series.

Good news that sprtoll() is available on your system, one more simple change to shc.c should get you going (don't forget to make it again after change):

replace:
Code:
"       if (date[0] && (atoll(date)<time(NULL)))",

with:
Code:
"       if (date[0] && (sprtoll(date,(char **)NULL,10)<time(NULL)))",

Eureka!

I guessed that you meant strtoll where you had sprtoll.

It works wonderfully! Ther only thing I have to do is to ensure that LIBPATH includes /usr/lib at runtime. It is a pain because some idiot (and I don't mean me for a change) has hardcoded something else in /etc/profile. That will be fun to get changed.


Anyway, many, many, many, many thanks! SmilieSmilieSmilieSmilieSmilie


Let's see what contest the cricket brings now.....Smilie

Come on the Poms! Smilie

Actually, let's just have a good game like the last one, preferably with the other result, but hey let's have fun.
