DAHDI 2.6.1 pcap compilation error

Asterisk Asterisk Support
1

Hi,
I’m trying to compile dahdi 2.6.1 with pcap enabled.
OS is centos 5.4 32bit (but I get the same error on ubuntu 12 64bit)
libpcap.i386 14:0.9.4-15.el5 installed
libpcap-devel.i386 14:0.9.4-15.el5 installed

If I compile a non modified source tree everything is OK.
I follewed the mailing list tips and I’ve succesfully compile the mirror-enabled drivers (modified the dahdi_config.h)
When I edit the tools/Makefile and add dahdi_pcap to the UTILS, BINS plus the “dahdi_pcap: LIBS+=-lpcap” line I get the following linker error (added a --verbose gcc flag):

make[1]: Leaving directory `/root/dahdi-linux-complete-2.6.1+2.6.1/tools'
make: *** [all] Error 2

Now as far as I know the collect2 line means that I’m missing some library but I can’t find a clue about which one

Any odea on what’s wrong with my setup ?

thanks a lot !

As of dahdi-tools 2.6.0, there is no need to modify the Makefile to make the dahdi_pcap tool.

cd linux/
make dahdi_pcap

Should be all that’s required.

thanks, that works fine
