There have been a number of posts about compilng exits and I have tried their suggestions in building an exit (specifically in this case mirrorq) for Solaris WMQ 6.0.2.1 (64Bit)
There was even a doc update that gave revised instructions for building the exit yet it seems no matter what I do, the exit fails to load.

finally looking at the binary produced,

-bash-3.00$ file mirrorq

-bash-3.00$
[/lcode]
I get exactly the same results with the sample exit supplied with WMQ.
Any hints/tip about where to go next would be much appreciated.
TIA

I included the wrong compiler script in my original post.
It should be
cc -V -xarch=v9 -KPIC -mt -G -o mirrorq mirrorq.c -I/opt/mqm/inc -L/opt/mqm/lib64 -R/opt/mqm/lib64 -R/usr/lib/64 -lmqm -lmqmcs -lmqmzse -lsocket -lnsl -ldl -DUNIX -DSOLARIS -D_REENTRANT -DHNLUP

Looks like you have a few things to correct.
A) you say you compiled with 64 bits but you placed the exit in the 32 bit part of the exit directory??
B) you need to compile for both 32 bits AND 64 bits and place the executable into its respective directory
Enjoy

The exit as compiled for 64bit is in the exits64 directory
There is also a version of the exit in the exits. This is compiled for 32bit.

Looks like a linking problem. Verify what kind of lib is in /usr/lib/(32/64bit)...
Make sure each of the libraries (32 bit/64bit) links to its respective 32/64 bit counterpart....
Last but not least is the user root supposed to be running this stuff?
See the qmgr log where it says user root.
I would start the qmgr as mqm... maybe you'll get a different result...
Have fun...

One of the things I do on Unix/Linux is to put root into the MQM group.
This allows root to start/stop queue managers. I think its in the docs somewhere...
Anyway, I tried to start the QMGR as another user and there is no change to the messages in AMQERR01.LOG
I did an LDD -v on BOTH 32 & 64 bit exits binaries.
there seems to be no conflict here. The 64bit references the 64 bit versions of libraries
For Example:-
| Code: |
-bash-3.00$ ldd -v mirrorq
find object=libmqm.so; required by ./mirrorq
libmqm.so => /opt/mqm/lib64/libmqm.so
find object=libmqmcs.so; required by ./mirrorq
libmqmcs.so => /opt/mqm/lib64/libmqmcs.so
find object=libmqmzse.so; required by ./mirrorq
libmqmzse.so => /opt/mqm/lib64/libmqmzse.so
find object=libsocket.so.1; required by ./mirrorq
libsocket.so.1 => /usr/lib/64/libsocket.so.1
find object=libnsl.so.1; required by ./mirrorq
libnsl.so.1 => /usr/lib/64/libnsl.so.1
find object=libdl.so.1; required by ./mirrorq
libdl.so.1 => /usr/lib/64/libdl.so.1
find object=libmqmcs.so; required by /opt/mqm/lib64/libmqm.so
find object=libmqmzse.so; required by /opt/mqm/lib64/libmqm.so
find object=libthread.so.1; required by /opt/mqm/lib64/libmqm.so
libthread.so.1 => /lib/64/libthread.so.1
find version=libthread.so.1
libthread.so.1 (SUNW_0.9) => /lib/64/libthread.so.1
find object=libsocket.so.1; required by /opt/mqm/lib64/libmqm.so
find object=librt.so.1; required by /opt/mqm/lib64/libmqm.so
librt.so.1 => /lib/64/librt.so.1
find object=libc.so.1; required by /opt/mqm/lib64/libmqm.so
libc.so.1 => /lib/64/libc.so.1
find version=libc.so.1
libc.so.1 (SUNW_0.7) => /lib/64/libc.so.1
|
and for the 32bit
| Code: |
-bash-3.00$ ldd -v mirrorq
find object=libmqm.so; required by ./mirrorq
libmqm.so => /usr/lib/libmqm.so
find object=libmqmzf.so; required by ./mirrorq
libmqmzf.so => /usr/lib/libmqmzf.so
find object=libmqmcs.so; required by /usr/lib/libmqm.so
libmqmcs.so => /opt/mqm/lib/libmqmcs.so
find object=libmqmzse.so; required by /usr/lib/libmqm.so
libmqmzse.so => /opt/mqm/lib/libmqmzse.so
find object=libthread.so.1; required by /usr/lib/libmqm.so
libthread.so.1 => /usr/lib/libthread.so.1
find version=libthread.so.1
libthread.so.1 (SUNW_0.9) => /usr/lib/libthread.so.1
find object=libsocket.so.1; required by /usr/lib/libmqm.so
libsocket.so.1 => /usr/lib/libsocket.so.1
find object=librt.so.1; required by /usr/lib/libmqm.so
librt.so.1 => /usr/lib/librt.so.1
find object=libc.so.1; required by /usr/lib/libmqm.so
libc.so.1 => /usr/lib/libc.so.1
find version=libc.so.1
libc.so.1 (SYSVABI_1.3) => /usr/lib/libc.so.1
find object=libdl.so.1; required by /usr/lib/libmqm.so
libdl.so.1 => /usr/lib/libdl.so.1
find object=libmqz.so; required by /usr/lib/libmqm.so
libmqz.so => /opt/mqm/lib/libmqz.so
find object=libmqmcs.so; required by /usr/lib/libmqmzf.so
find object=libthread.so.1; required by /usr/lib/libmqmzf.so
find version=libthread.so.1
libthread.so.1 (SISCD_2.3a) => /usr/lib/libthread.so.1
find object=libsocket.so.1; required by /usr/lib/libmqmzf.so
find object=librt.so.1; required by /usr/lib/libmqmzf.so
find object=libc.so.1; required by /usr/lib/libmqmzf.so
|
So, as far as I can see, everything is in the right place and linked correctly.
Any other thoughts most welcome

Thanks for the suggestions. I had already tried the compiler commands based upon the API guide.
Anyway, I rebuilt both 32 & 64 bit versions of the exit again and put them in place.
The result when trying to start the QMGR is the same as before.

this module.
EXPLANATION:

'/var/mqm/exits64//mirrorq' failed to load correctly due to a problem with the

You've still got a trailing slash in ExitsDefaultPath and ExitsDefaultPath64.
I'm really not kidding when I say to try this, and it's not ... entirely ... a random suggestion.
What lib file is supposed to export MQXEP?

Jeff,
The trailing '/' are put in the qm.ini by WMQ when it creates the QMGR....
Anyway, I tried it without them and there was no difference apart from the path not showing the double //.
| Code: |
07/25/07 14:54:05 - Process(1479.1) User(sdavi) Program(amqzxma0_nd)
AMQ6175: The system could not dynamically load the shared library
'/var/mqm/exits64/mirrorq'. The system returned error message 'ld.so.1:

Regarding the MQXEP. I did a grep of mirrorq.c and found
| Code: |
-bash-3.00$ grep -i mqxep *.c
MQXEP(pExitParms->Hconfig, MQXR_BEFORE, MQXF_CLOSE, (PMQFUNC) CloseBefore,
MQXEP(pExitParms->Hconfig, MQXR_AFTER, MQXF_CONN, (PMQFUNC)ConnAfter,
MQXEP(pExitParms->Hconfig, MQXR_AFTER, MQXF_CONNX, (PMQFUNC)ConnxAfter,
MQXEP(pExitParms->Hconfig, MQXR_BEFORE, MQXF_DISC, (PMQFUNC)DiscBefore,
MQXEP(pExitParms->Hconfig, MQXR_AFTER, MQXF_OPEN, (PMQFUNC)OpenAfter,
MQXEP(pExitParms->Hconfig, MQXR_AFTER, MQXF_PUT, (PMQFUNC)PutAfter,
MQXEP(pExitParms->Hconfig, MQXR_AFTER, MQXF_PUT1, (PMQFUNC)Put1After,
MQXEP(pExitParms->Hconfig, MQXR_CONNECTION, MQXF_TERM, (PMQFUNC)Terminate,
-bash-3.00$
|
MQXEP is defined in cmqcx.h which is an include in the .c file.
the output from the 'ldd' command shows no undefined references so AFAICG (As far as I can guestimate) it is a compile/link issue. But quite what it is I am at a bit of a loss.

Jeff,
(You must have big pockets for a complete wall eh?)
I've run into the problem with unsupported C compilers before (with Broker 2.1 and gcc when sun couldn't sell us a c compiler) so I have a supported compiler.(AFAIK)
Viz
cc -V
cc: Sun C 5.8 2005/10/13
This is from a SunStudio install.
Any more suggestions welcome.

The secret is to use very small bricks... 
The other thing to check is that you have UNSET Lib and LD_LIBRARY_PATH, per "implications of a 64bit queue manager" (Solaris Quick beginnings manual).
