Hey friends, Yestarday I installed FC3 through NFS .I wanted to test Mail Scanner with clamav + postfix.While installing MailScanner it said there are no /usr/src/redhat directory. I was surprised to see that redhat directory under /usr/src was not there.I created redhat directory under /usr/src .Under redhat directory I created RPMS,BUILD,SOURCES,SPECS,SRPMS subdirectories and under RPMS subdirectory I created athlon,i386,i486,i586,i686 and noarch directories. I again tried to install MailScanner and it keep showing this while installing Missing file /usr/src/redhat/RPMS/noarch/perl-Net-CIDR-0.10-1.noarch.rpm. Maybe it did not build correctly? Attempting to build and install perl-IO-stringy-2.108-1 --rebuild: unknown option It keeps coming for every rpm under MailScanner.I tried to install those .src.rpm manually.They got installed but when i tried to build them rpmbuild -ba perl-Net-CIDR-0.10-1.spec. "It said file not found." I forget to install the software development tools while installing the FC3 .But later on whatever libraries and programs (make,binutils,gcc) which were needed by MailScanner I installed it.I have only selected KDE and X windows for Desktop Environment. a)I want to know the reason for /usr/src/redhat directory missing at the first place b) What I have to do to make MailScanner installed properly.
