I'm currently installing Jazz CALM solution on CentOS 4 64bit (equivalent to RHEL 4 64bit). I got stuck when installing both Rational Quality Manager (RQM) and Rational Requirements Composer (RRC). Both need to be installed via IBM Installation Manager. RRC installation package includes IBM Installation Manager, whereas RQM doesn't.
To install IBM Installation manager on 64bit RHEL 4 you first need to install these:
yum install gtk2.i386 libgcc.i386
I first installed libgcc.i386 only to get rid of the error message
libgcc_s.so.1 must be installed for pthread_cancel to work
After this, there was no error message, but the installer returned exit code 13 (which I haven't found documented anywhere). Installing 32bit gtk library solved the problem.
The IBM Installation Manager itself can be downloaded from ftp://public.dhe.ibm.com/…alsdp/v7/im/
I hope this helps somebody save some time of desperate googling for solution…
