Hi Rakesh,

libcap (for setting system capabilities) is different from libpcap (for port capture, used by tcpdump/wireshark/ethereal/etc.).

Regards,

Scott

Hi,
 
I have now libcap compiled statcally on my machine , but still I face the same error.
 
the static libcap is present under /sur/locla/lib
/usr/local/lib/libpcap.a
 
But for some reason it does not seem to recognize that.
 
gcc -std=gnu99  -g -O2 -Wall  -L/usr/local/lib -o syslog-ng main.o libsyslog-ng.a -static   -lrt -lnsl -lfl -L/usr/local/lib -lglib-2.0 -liconv   -L/opt/soe/local/syslog-ng-3.0.7/eventlog/lib -levtlog     -ldl  -lwrap   -lcap   globals.o
/usr/local/bin/ld: cannot find -lcap
collect2: ld returned 1 exit status
make[2]: *** [syslog-ng] Error 1
make[2]: Leaving directory `/compile/syslog-ng-3.0.7/src'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/compile/syslog-ng-3.0.7'
make: *** [all] Error 2
[root@CSCSVSLGG189v syslog-ng-3.0.7]#
I have tried to tweak with the entry in the Makefile but that does not seem to help.
DEPS_LIBS = -static   -lrt -lnsl -lfl -L/usr/local/lib -lglib-2.0 -liconv   -L/opt/soe/local/syslog-ng-3.0.7/eventlog/lib -levtlog     -ldl  -lwrap   -lcap
 
Please advice.
 
Thanks & regards,
Rakesh

Looks like it needs libcap, a static version.
