Hi, I just installed fc3, and try to install clamav on it. I added crash-hat.repo that points to http://crash.fce.vutbr.cz/crash-hat/$releasever then, try to install clamav 8.0 by using yum. However, I got: # yum install clamav .... clamav-0.80-4.i386.rpm 100% |=========================| 2.2 MB 00:04 warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 6cdf2cc1 public key not available for //var/cache/yum/crash-hat/packages/clamav-0.80-4.i386.rpm So, it is not installed. Then, I try tarball. The configure command does not show error. However, when I run make, I got: # make ... gcc: /usr/lib/libidn.so: No such file or directory make[2]: *** [libclamav.la] Error 1 make[2]: Leaving directory `/usr/local/src/clamav-0.80/libclamav' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/local/src/clamav-0.80' make: *** [all] Error 2 # and so cannot install it. Can somebody help me: 1. To use yum, how to get public key for clamav? Should I do something first? 2. To use tarball, how to solve the problem of "gcc: /usr/lib/libidn.so: No such file or directory" and other errors? Thanks! Hongwei Li
