Chkrootkit installation error: / usr/bin/ld: cannot find-lc
Chkrootkit is a tool that checks rootkit traces on the local system. It is a shell script that checks whether the system binaries have been modified by the rootkit virus.
System environment Centos 6.4
Chkrootkit-0.50 (currently the latest version)
# tar xf chkrootkit.tar.gz
# cd chkrootkit
Chkrootkit-0.50/ chkrootkit.tar.gz
# cd chkrootkit-0.50/
# make sense
Cc-DHAVE_LASTLOG_H-o chklastlog chklastlog.c
Make: cc: Command not found
Make: * * [chklastlog] Error 127
# yum install gcc
And then make sense again.
Cc-DHAVE_LASTLOG_H-o chklastlog chklastlog.c
Cc-DHAVE_LASTLOG_H-o chkwtmp chkwtmp.c
Cc-DHAVE_LASTLOG_H-D_FILE_OFFSET_BITS=64-o ifpromisc ifpromisc.c
Cc-o chkproc chkproc.c
Cc-o chkdirs chkdirs.c
Cc-o check_wtmpx check_wtmpx.c
Cc-static-o strings-static strings.c
/ usr/bin/ld: cannot find-lc
Collect2: ld returned 1 exit status
Make: * * [strings-static] Error 1
After searching for this mistake online for a long time, I finally found the answer on a fedora-related forum. Personally, I feel that this error is not often encountered when others install it, or it is directly installed by yum.
# yum install glibc-static
# make clean
# make sense

Chkrootkit will scan the important files in the system, and the above results show that the system is relatively clean.
It can be added to crontab scheduled tasks and scanned regularly, depending on the situation.
