Hi,
As part of the MQ8 upgrade, we need to recompile and relink the old cobol client application which was referring to libmqmcs and libmqmcb libraries before.
Now as in MQ8, libmqmcs is deprecated and not advised to use, we have removed it while linking. But after that getting error:
symbol referencing error in libmqmcb.so
Kindly help. |

Can you supply some more detail? Your build commands, a bit more detail around the error etc.

We are using cob command to link the MQ library - libmqmcb and getting the below error:
undefined symbol first referenced in
xcsConverString in /app/mqm/opt/lib64/libmqmcb.so
CSCtrl in /app/mqm/opt/lib64/libmqmcb.so
and few more variables.
but if we link the files using cob with both the libraries libmqmcb and libmqmcs, it is able to link. But then going forward gives the 2012 Environment issue. |

What was the complete 'cob' command you executed?
What o/s? IBM MQ v 8.0.0.0? Which COBOL compiler?

Are you sure your /app/mqm/opt/lib64/libmqmcb.so is a v8 file?
When I use the nm command to list the symbols in either the 7.5 or 8.0 version of libmqmcb.so, I don't see either of these symbols:
xcsConverString
CSCtrl

OS is solaris. and MQ version is 8.0.0.4.
I can see the variables defined in libmqmcs.so but undefined in libmqmcb.so, but their presence is there(as UNDEF) when I run nm command. |

Ok, I checked this out on Solaris for 8.0.0.4 and I see what you are saying. Those two symbols you mentioned were added into the libmqmcb.so at 8.0 (don't see them in 7.5) and the only shared object file that I see those symbols globally defined in is the libmqmcs.so. Maybe check this out with IBM in a PMR? My only other advice is make sure you are following the manual recommendations on how to build COBOL programs on Solaris.
