If I try to build grub in mock, I get: No Package Found for /usr/lib/crt1.o 0:binutils-2.17.50.0.6-9.el5.x86_64 0:ncurses-devel-5.5-24.20060715.x86_64 Cannot find build req /usr/lib/crt1.o. Exiting. Johnny Hughes explained the reason for the failure in his CentOS Forum post on 2008/02/09: http://www.centos.org/modules/newbb/viewtopic.php?topic_id=12491&forum=38&post_id=41509#forumpost41509 Excerpt: ---------------------------------------------------------------- There is a known bug in the yum that ships with centos-5 (and rhel-5) ... version 3.0.x ... where BuildRequires that are in the form of BuildRequires: <file_path> do not work. This bug will take any file, the first one it finds actually, and use it to meet the build requirement ... not the one specified by the full path. SO ... in this case the problem is that the grub spec file has this line for the x86_64 package build: BuildRequires: automake /usr/lib/crt1.o The problem is that what needs to be installed is glibc-devel.i386 ... however a different package meets that require due to the bug, and the build fails (if using mock and centos-5 as the base). If you use centos-4 as the base os and setup mock to build centos-5 packages on that machine, then this package will build via mock. ---------------------------------------------------------------- This still happens with the current yum-3.2.19-18.el5.centos.noarch (and mock-0.6.13-1.el5_2.3.x86_64) in CentOS-5.
