C++ 64-bit MQSeries Apps

[Puvvada]

Hi,

MQ Series Ver 5.2, AIX 4.3

I am trying to compile a 64-bit MQ App. I downloaded a support pack provided by IBM for 64-bit MQ clients. But my application runs on the MQ server itself. I tried to compile the sample C++ application imqsget.cpp by linking the 64-bit libraries. But I get the following errors.

/usr/ibmcxx/bin/xlC -q64 imqsget.o /usr/lpp/xlC/lib/libC.a /usr/mqm/lib64/libimqb23ia.a /usr/mqm/lib64/libmqic.a /usr/mqm/lib64/libmqicb.a /usr/mqm/lib64/libmqmcsc.a /usr/mqm/lib/libimqs23ia.a -o imqsget

If anyone tried to compile a 64-bit app before, please share your experiences with me.

Thanks

Hi,

I have a similar compile/link problem, did you find out anything about this in the meantime?

Thanks... Dominik.

It seems that compiling with 64-bit for MQSeries is currently a problem.


I did a quick search and found out the following:

doing a
nm -C /usr/lib/libimq* | grep setOpenOptions

on the 32-bit libraries gives the following:

[208] | 67708| 116|FUNC |GLOB |0 |9 |unsigned char ImqObj::setOpenOptions(const long)

and doing a
nm -C /opt/mqm/lib64/libimq* | grep setOpenOption

on the 64-bit libraries gives

[288] | 64704| 136|FUNC |GLOB |0 |9 |unsigned char ImqObj::setOpenOptions(const int)


Note the difference in parameters "const long" and "const int".

It seems that the set of exported methods is not the same for the 32-bit libraries and the 64-bit libraries. The header files contain information that does not match the methods contained in the 64-bit-libraries.

This may also be related to the fact that we are using CSD03 (Patch/ServicePack 3) of the base client-installation and there is no new 64-bit package with this patchlevel. We need to test this by installing the client-installation without patchlevel and the corresponding 64-bit libraries to see if this can work.


On the other hand it seems this one is for IBM Support to release a new 64-bit package!
