The Intel® Debugger idb is built against libXft.so.1, which doesn't exist on Fedora* Core 6 or Red Hat* EL 5.0. Trying to execute the debugger will cause the following error: "error while loading shared libraries: libXft.so.1: cannot open shared object file: No such file or directory".
A work-around is for the system administrator (requires root account access) to create a symbolic link in /usr/lib from libXft.so.1 to libXft.so.2:
% cd /usr/lib
During installation of idb, the installer will detect the failed RPM dependency, and suggest a work-around for the system administrator:
For example: ln -s /usr/lib/libXft.so.2 /usr/lib/libXft.so.1. This must be done to install idb. Please contact Intel® Premier Support so you can be notified when a version of idb is available that avoids this problem, or if you have questions on this note.
