Okay, creating a script: #!/bin/sh if [ -x /usr/lib/rpm/redhat/find-requires ] ; then FINDREQ=/usr/lib/rpm/redhat/find-requires else FINDREQ=/usr/lib/rpm/find-requires fi $FINDREQ $* case `uname -m` in *64) echo 'libisl.so.15()(64bit)' ;; *) echo 'libisl.so.15()' ;; esac gives me the following: warthog>rpm -qpR x86_64/gcc-x86_64-linux-gnu-6.3.1-1.fc26.x86_64.rpm ... libisl.so.15()(64bit) ... which seems more or less what I was looking for. Deciding whether or not I want to include the "(64bit)" flag is another issue to be solved.
