Hi!
I wrote small c application. It must work on HPUX and put messages to queue on Windows server.
I did not install mqseries on HPUX, but I have all libraries at /opt/mqm/lib.
And when I try to compile it
apxs2 -i -c mod_aqtmon.c -L/opt/mqm/lib -llibmqm
error message is appear:
ld: cannot find -llibmqm
collect2: ld returned 1 exit status
apxs:Error: Command failed with rc=65536
It's strange, because I have this library at /opt/mqm/lib
Anybody knows what does it mean? |

You can't do this without installing MQ.
Also, you need to go back to the Application Programming guide, and read it's discussion on client versus server connections - and make sure you know which one you are trying to create!
Hint: If there isn't a queue manager on HP, you can't make a server connection.

Here's a makefile I use to compile C programs on HP-UX. You may want to try it:
restrictions as set forth in sub-paragraph (c)(1)(ii) of the Rights in
Technical Data and Computer Software clause in DFARS 252.227-7013.
Hewlett-Packard Company
all: testrecioread
TARGET = testrecioread
CC = cc
CCOPTS = -c -DUNIX -Ae
INCLUDE = -I. -I/home/mqm/tools/source/COMMON -I /home/mqm/tools/source/MQMFTPV2 -I/opt/mqm/inc
MQMLIB = /opt/mqm/lib
LIBS = -lm -lmqm
OBJS = testrecioread.o
PROG = testrecioread
$(PROG): $(OBJS)
$(CC) -o $(PROG) $(OBJS) -L$(MQMLIB) $(LIBS) $(INCLUDE)
testrecioread.o: testrecioread.c
.c.o:
$(CC) $(CCOPTS) $(INCLUDE) $< |

All compiler I know uses -lmqm not -llibmqm
Maybe thats your problem.

There are really a few problems.
The first is trying to compile against an improper MQ installation. You need at least an MQ Client installed.
The second is probably using "libmqm" instead of "mqm".
The third is it needs to be mqic, and not mqm, as this appears to need a client connection.
The fourth is that mushroom didn't read the appropriate sections of the Application Programming Guide and the Quick Beginnings guide for HP.

Thank you all,
I thought I don't need to install MQ, because early I ran my java application on the station without MQ and it worked.
I don't understand, why c-application is different? |

Because C & Java handle libraries differently. Same reason you can't get orange juice from an apple even if you use an orange squeezer...

Your Java application should use the MQ install, too.
If you're moving the mq jar files around manually, then a) you're never quite sure what version of the jars you're using, and b) you're in an unsupported configuration - as far as I know.

No runtime environment is nessessary.
It's ok, if the compiler finds the header and the linker the libraries.

The client has no runtime environment - it's a series of libraries and headers. All the good stuff is done by the queue manager as part of the syncronous activity.

I personally wouldn't want to try and copy all necessary libs and headers for the purposes of compiling - particularly for building server applications - too messy and fraught with potential for error. Plus, no way to know what version the libs and headers are!
Plus, it's a non-supported install.

It's only possible to install one mq-server and/or one mq-client, so you need one system for every mq version and maybe for every CSD, Fixpack, Refreshpack.
For every mq server you need an mq license, even if it is only used to compile the code.

IMHO it's bad housekeeping to have that many levels of software around. It makes problem resolution tricky because you can never be sure what level a given machine is on. Personally I prefer to upgrade in waves - one dev sandbox, rest of dev, unit testing, regression testing, etc all the way to production and not restart the cycle until prod is at that level.

True, but development is typcialy done on clients grouped round a single dev queue manager for exactly this reason.

Now I have working C application without local MQ installing.
So, it's possible.
It was the problem when I try to link wrong library.
P.S. Vitor, it seems, I can teach you how to make orange juice from an apple. |
