Could it be the reason ??? ) |

Using a myexit.def file :
Its contents is :
+++
LIBRARY exit
PROTMODE
DESCRIPTION ’Provides Retry and Channel exits’
CODE SHARED LOADONCALL
DATA NONSHARED MULTIPLE
HEAPSIZE 4096
STACKSIZE 8192
EXPORTS Retry
+++
The CL resuts are now :

Solution :
myexit.def file with :
+++
LIBRARY GNX2
PROTMODE
DESCRIPTION 'GN Channel Translation Exit'
CODE SHARED
DATA NONSHARED MULTIPLE
HEAPSIZE 16384
STACKSIZE 16384
EXPORTS gna @1
+++
Compile as this :
+++
CL /MD /GD /V"versio 1.2" /LD /I"C:\Program Files\IBM\WebSphere MQ\Tools\c\include" GNX2.C "c:\Program Files\IBM\WebSphere MQ\Tools\Lib\mqm.lib" "c:\Program Files\IBM\WebSphere MQ\Tools\Lib\mqmvx.lib" -DEFAULTLIB myexit.def

Hya chaps ... I've added my related problem to this thread. Hope it's ok.
basically, I've got a chl exit that checks the incoming IP address, and check that against a file of 'allowed' IP addresses. Nice and simple and it works fine under Linux (V5.3 CSd12)
I'm now porting it to Sun Solaris (MQ V5.3 CSD7) and the first hurdle was trying to find the 'correct' parameters for gcc to work. The IBM Intercommuncation manual is not exactly very helpful.
I did, however, find the following link useful: http://www.mail-archive.com/mqseries@listserv.meduniwien.ac.at/msg05999.html
The first issue however, is that the -lmqm_r parameter does not work under Solaris, so I left it off. It then compiled/linked ok, but than gave the AMQ6175 error, e.g.
07/27/06 14:46:34
AMQ6175: The system could not dynamically load the library
/var/mqm/exits/eqits_IPexit. The error message was ld.so.1: amqcrsta: fatal:
libgcc_s.so.1: open failed: No such file or directory. The queue manager will
continue without this module.
I then followed the 2nd suggestion in the weblink, which was to use the -R parm to specifically give it the reference to file libgcc_s_so.1 (which fyi was libgcc_s.so.1 => /sbcimp/run/pd/gcc/3.2.1/lib/libgcc_s.so.1 - using the ldd output).
So the -R was supplied to gcc, recompiled/linked and now I've got the dreaded SIGSEGV FDC.
I'll start by chaning the code so that initially it does nothing, and then gradually add more and more code, but I'm more concerned with the gcc queries.
Regards ... R |

problem solved. For some reason a 'strcpy' which worked fine under Linux had to be replaced by a 'strncpy'.
I am still running with the -R gcc parm.
Cheers ... R |

Since the original question was for a problem on Windows, it might have been more helpful to have this new question in a new thread.
It looks like I'm the first to say it, but it needs to be said: On Solaris, MQ has been compiled with the Sun compilers, and all testing etc. is done with programs, shared libraries etc. compiled with the Sun compilers. If you get stuff to work that's been compiled with gcc, then great. However, I think I have to point out that IBM Support will not be able to support your MQ system through any related problems you might encounter.
See http://www.ibm.com/support/docview.wss?rs=171&uid=swg27006263 for the official list of supported environments. |
