Hi all, When trying to rpmbuild http://robert.cheramy.net/ipfm/browser/trunk/redhat/ipfm.spec, I do this: [mihamina at centos6-01 redhat]$ rpmbuild -ba ipfm.spec error: line 5: Unknown tag: Licence: GPL And I get the error above. [mihamina at centos6-01 redhat]$ head -n 5 ipfm.spec Summary: IP Flow Meter is a bandwidth analysis tool Name: ipfm Version: 0.12.0rc1 Release: rktmb Licence: GPL [mihamina at centos6-01 redhat]$ There, I changed the original "Copyright:" to "Licence:", but I get the same error with "Copyright:" (but mentioning "Copyright:"). http://www.rpm.org/max-rpm-snapshot/s1-rpm-inside-tags.html says "Licence:" is a valid tag. Isnt'it? These are my rpm installed. [mihamina at centos6-01 redhat]$ rpm -aq | grep rpm rpm-python-4.8.0-19.el6_2.1.x86_64 deltarpm-3.5-0.5.20090913git.el6.x86_64 rpm-4.8.0-19.el6_2.1.x86_64 rpm-build-4.8.0-19.el6_2.1.x86_64 redhat-rpm-config-9.0.3-34.el6.noarch rpm-libs-4.8.0-19.el6_2.1.x86_64 Thank you. -- RMA.
