we are using g++ (GCC) 4.2.0 complier to compile some c++ programs which is using MQ API calls in AIX 5.3.0.0 .
Compiling is OK and able to create .o files , but when we link those files using g++ -o
It is giving us errors like
ld: 0711-317 ERROR: Undefined symbol: .ImqObj::setConnectionReference(ImqMgr*)
ld: 0711-317 ERROR: Undefined symbol: typeinfo for ImqErr

ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.
we are using the commands :-
g++ -c sample1.cpp
g++ -c sample2.cpp
g++ -o out sample1.o sample2.o -L/usr/mqm/lib64 -limqb23ia -limqb23ia_r -limqs23ia.a -limqs23ia_r.a
The required lib files exist in both /usr/mqm/lib64 and current working dir .
It seems the complier not able to find mqlibraries
Can any one able to help on this ?
IS g++ version4.2.0 will support MQ API calls on AIX 5.3.0.0
Best Regards

I thought that mqb23ia_r was the threadsafe version of mqb23ia and as such you would only have one of them on your link table...
But my knowledge in this area is severely restricted so:
- check the programmers manual and reference 
It should have enough information for you to get out of this mess.

g++ (GCC) is NOT supported on AIX (C++ linked objects are a different kind of beast).

You're writing an exit in C++?
You need to use a supported compiler on AIX to compile any MQ applications, this includes exits. There may not be a free one. |
