I am trying to complie the IBM supplied C++ sample imqwrld program on RedHat Linux 8.0 using the GNU g++ version 3.0.3 compiler. I have WebMQ v5.3 server installed. Following the instructions in the IBM WebMQ Using C++ manual I issue the following command from the shell:
g++ -o /home/kbsinc/bin/imqwrld /home/kbsinc/cpp_source/imqwrld.cpp -fsigned-char -I/opt/mqm/inc -L/opt/mqm/lib/3.0.3 -Wl,-rpath/opt/mqm/lib/3.0.3 -limqb23gl -limqs23gl
The compiler generates the error: /usr/bin/ld: bad -rpath option
collect2: ld returned 1 exit status
If I remove the -Wl,-rpath option, the compiler generates the error: /usr/bin/ld: warning: libstdc++.so.3, needed by /opt/mqm/lib/3.0.3/libimqb23gl.so, not found (try using -rpath or -rpath-link).
I have this exact sample compiled and working successfully on Windows 2000 using MS Visual C++. Can anyone point me in the right direction? Thanks...

It appears that your problem is specifically related to compiling and linking than on the source itself. I have not had this issue when installing or using MQ in Linux.
I am running
$ mqver
MQSeries Version: 520
CMVC level: p000-L001106
BuildType: IKAP - (Production)
So I don't have 5.3 yet... In the mail.... So I do not have the 3.0.3 library set... But I ran your compile statement and noticed that I got the same error you did.... add a space after the -rpath before the library directry.... This then gave me a different error... Because I do not have the 3.0.3 libraries...
So I that if you have the directory 3.0.3 under the /opt/mqm/lib directory then you should be ok. So try it with the space in there and see if it works. |

Leaving a space after the -rpath option and before the directory just causes the -rpath option to be ignored and produces the same error as documented in original post:
" /usr/bin/ld: warning: libstdc++.so.3, needed by /opt/mqm/lib/3.0.3/libimqb23gl.so, not found (try using -rpath or -rpath-link). "
The /opt/mqm/lib/3.0.3 directory and shared library members exist as well. Thanks...
