Re: unable to use mock



Hi,
    I executed yum --installroot
/var/lib/mock/fedora-development-i386-core/root 
groupinstall build-minimal build-base build
 as root and it takes much time and installed 140
packages. Then i restart system. As mock does takes a
srpm and builds it in a chroot. So i created as root
one SRPM from SPEC file as
rpmbuild -bs foo.spec
then i did
su - build
then i gave
 mock -r fedora-5-i386-core.cfg foo.src.rpm  
and its output is still
init
clean
prep
This may take a while
Error peforming yum command: /usr/sbin/mock-helper yum
--installroot
/var/lib/mock/fedora-development-i386-core/root
groupinstall build build-minimal build-base
ending
done

So i try to execute 
 yum --installroot
/var/lib/mock/fedora-development-i386-core/root 
groupinstall build-minimal build-base build
and its output is

OSError: [Errno 2] No such file or directory:

why its gave error now?? Then i check
 ls
/var/lib/mock/fedora-development-i386-core/root/var/cache/yum/core/
and found that it contains only
headers  packages
and not comps.xml
why??
