I've ported a C++ program from a Windows NT 4 environment to AIX 5.3. The program basically gets messages from an MQ Series queue and turns triggering on of another queue. Unfortunately I am not able to compile (and link) the program on the AIX platform. I keep getting the following error:
The following symbols are in error:
Symbol
.ImqBin::copyOut(void*,unsigned long,char)
.ImqObj::setOpenOptions(long)
.ImqCac::useEmptyBuffer(const char*,unsigned long)
The contents of the makefile is as follows:
===============================================
.SUFFIXES: .cpp .o
.DEFAULT: all
PROGRAM=myMQprog
SRCS=myMQprog.cpp
OBJS=$(SRCS:.cpp=.o)
CC=xlC
CC_FLAGS= -qnamemangling=v5 -I/usr/mqm/inc
-blibpath:"/usr/vacpp/lib:/usr/lib:/lib:/usr/vac/lib"
all: $(PROGRAM)
.cpp.o:
$(CC) $(CC_FLAGS) -c $<
myMQprog: $(OBJS)
$(CC) $(CC_FLAGS) $(OBJS) -L. -bnoquiet -L/usr/mqm/lib
-limqs23ia -limqb23ia -o $@
===============================================
Any ideas?
I'm not sure which MQ libraries to use. |

You did change the carriage returns/line feeds?
Most annoying part of Windows/AIX porting sometimes is hidden characters, particularly when you are using certain compliers.
The other thing I always warn people about is the directionality of slashes.

| I also suspected the embedded control characters and decided to compile one of sample MQ Series C++ programs - The result was a similar error i.e. unresolved symbol during the link process. |

Using the "-q namemangling=v5" option did not have any effect.
Thanks for all the help. |

Oopos - its a link time not compile time option. What compiler are you using to do this? Its an exact match for a problem reported, and this option did solve it for them!
To quote an update:

I have investigated the above problem and I was able to
recreate the problem on one of the AIX machines we have in
the lab. If the above assumption is correct, then I think
the customer has not used the VisualAge C/C++ v6.0 compiler
option "-q namemangling=v5" for C++ to get all the WMQ
symbols resolved while linking the libraries. Please
check the note in the following URL;

Even after using the "-q namemangling=v5" option I still get the same error.
Below is a snippet of the command executed on AIX.
xlC "-qnamemangling=v5" -I/usr/mqm/inc -blibpath:"/usr/vacpp/lib:/usr/li
b:/lib:/usr/vac/lib" myMQprog.o -L. -bnoquiet -L/usr/mqm/lib -limqs23ia -limqb23ia -o myMQprog
As you can see I tried using the "-q namemangling=v5". I removed the space between the q and n because the compiler did not like the syntax. |

Can you compile the c++ samples?
xlC -O -qnamemangling=v5 -c imqsput.cpp
xlC -I/usr/lpp/mqm/inc -limqc23ia -limqb23ia -o imqsput imqsput.o
is shown as working - does it for you? |

The comands:
xlC -O -qnamemangling=v5 -c imqsput.cpp
xlC -I/usr/lpp/mqm/inc -limqc23ia -limqb23ia -o imqsput imqsput.o
produced the following errors:

| What compiler version are you running? What version/fixpack of MQ? |

Hmmm - That has solved it for all problems reported by customers so far, so I really dont know, Sorry!
Unless someone comes up with a better solution, I would suggest raising it wih IBM and indicate the exact syntax you have used (including the option I mentioned) and the exact errors reported. |

I just tried this with WMQ 5.3 csd04 on aix 5.2 with VisualAge C++ v6 and it worked fine for me.
One note though, using -I on the link step doesn't do anything (that is for include path during compile) . Try
xlC -L/usr/lpp/mqm/lib -limqc23ia -limqb23ia -o imqsput imqsput.o
You shouldn't even need the -L because links to these libs should be in /usr/lib. But, by putting in the -L, you can be certain that you are picking up the correct libs.
