I am running Redhat 9, MQ5.3 and am having a problem with the impwrld example.
This seems to be a similar problem to one somebody has already asked about but there was no reply.

I try and build it as follows
g++ -o imqwrld 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

but get the error: /usr/bin/ld: bad -rpath option
collect2: ld returned 1 exit status

If I remove the -W1, rpath options, I get a warning: libstdc++.so.3, needed by /opt/mqm/lib/3.0.3/libimqb23gl.so, not found (try using -rpath or -rpath-link).

Looking in my usr/lib directory, I didn't have a libstdc++.so.3 so firstly tried to use a symbolic link with libstdc++.so.5 but that then causes a crash when it tries to delete memory in the setStorage function of the ImqQueue destructor. I found a copy of libstdc++.so.3 on the redhat 7.2 updates page but that now warns about a conflict between so.3 and so.5.

Can anyone tell me what I am doing wrong?
Thanks in advance
