No PCAP installed for 3.6.1 on CentOS 7

[Xyders]

Hello,

I installed 3.6.1 on CentOS7 using following commands:

CMAKE_OPT="-DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++"
cmake . $CMAKE_OPT -DUSE_GSL=1 -DUSE_PCAP=1 -DUSE_SSL=1 -DUSE_SCTP=1
make -j4

The same problem in #485 happened so I reused the commands in this issue.

But my problem was that PCAP was not build into it as the output of "sipp -v" was like:
SIPp v3.6.1-RTPSTREAM.

There was no error msg during my building so I don't know what was wrong.

BTW I tried 3.6.0 with ./configure --with-pcap --with-openssl and "sipp -v" showed SIPp v3.6.0-TLS-PCAP-RTPSTREAM.

Any comments would be appreciated.

I'm sorry. This is not sufficient info for me to solve. Please reopen when you have something that doesn't require me to install CentOS7 to test.

Here's some observation from my test. I installed both 7 and 8, and I found 3.6.0 on 7, and 3.6.1 on 8 both worked normally. The reason might be the version of libpcap, which is 1.5.3 on 7 and 1.9.1 on 8 by default yum install. Anyway at least I got the workaround in my environment.

👍

Glad you got it sorted.

... this is probably related to the CMake conversion though.

Possibly things start to work if one adds:

I'm not that intimate with cmake yet. (Make sure you make clean; rm -rf CMakeCache.txt CMakeFiles just in case).

@wdoekes I tried in your way and make again. It worked without problem. Now sipp -v showed SIPp v3.6.1-TLS-SCTP-PCAP-RTPSTREAM. Thank you for your solution!
