Trouble building using instructions in Read Me

[senderic]

I am following the instructions in the read me to build mgen and coming up with the following error:

[root makefiles]# make -f Makefile.linux 
g++ -c -g -DPROTO_DEBUG -DHAVE_GPS -DUNIX -Wall -Wcast-align -fPIC -DLINUX -DHAVE_SCHED -DHAVE_GETLOGIN -DHAVE_LOCKF -DHAVE_DIRFD -DHAVE_ASSERT  -D_FILE_OFFSET_BITS=64 -DUNIX -DUSE_SELECT -DUSE_TIMERFD -DHAVE_PSELECT -DHAVE_IPV6 -DHAVE_PCAP -I/usr/X11R6/include  -I../makefiles -I../include -I../protolib/include -o ../src/common/mgenApp.o ../src/common/mgenApp.cpp

make: *** [../src/common/mgenApp.o] Error 1

It seems like an expect pcap.h file is not there. I tried manually searching for it and came up dry, except for ezx-pcap.h in unrelated directories:

[root mgen-master]# find / -name "*pcap.h*"
/usr/src/kernels/3.10.0-1062.18.1.el7.x86_64/include/linux/mfd/ezx-pcap.h
/usr/src/kernels/3.10.0-1062.18.1.el7.x86_64.debug/include/linux/mfd/ezx-pcap.h

Now, I suspect since git is just taking the master branch that the instructions may want us pointing to a release version or some previous version. I tried a variety of them such as 5.02, 5.02c and protolib 3.0b1, etc. No combination worked (though the errors were a bit different each time).

My set up is Centos 7 and I'm experimenting doing this with Docker. That said, I tried the executable in the release .tgz file however that had no effect.

I attached my docker files and the command I use to build: docker build --rm -t local/c7-systemd . -f Dockerfile-centos-systemd docker build -f Dockerfile-centos . -t rmbn-test-centos (Remove the .txt extension from the files, I needed to add to upload)

Dockerfile-centos-systemd.txt Dockerfile-centos.txt

It'd be great if we can review the make process? And maybe, if possible, instead of manually making this, it could be added to the mgen release assets?

The PCAP development library should be available in your standard Linux OS packages. yum install libpcap-devel, apt-get install libpcap-dev, etc. Then re-run the make line and that error should disappear.

Excellent! The make process completes, although when I try to run mgen, bash can't find the command. Also when I search the machine for mgen, nothing comes up..

The executable has been built, but not installed into your system/anywhere in your PATH. The 'mgen' executable is in the 'makefiles' directory where you ran the make command. You have various options: 1) You can run it from that directory as ./mgen, 2) You can run it from anywhere as /path/to/mgen (whatever that path is to the mgen executable in your makefiles directory 3) You can copy or symlink the mgen executable to somewhere that's in your PATH (/usr/local/bin usually works) 4) You can add the MGEN 'makefiles' directory to your PATH (method differs depending on OS, shell, etc.)

Thank you!
