Hello, i am trying to build it on FreeBSD 12.2, i had the following error

gmake freebsd echo "const char *gitversion = "b8e9095135ec898cc5826f0c216dd3c120b5cafc";" > git_version.h g++ -o udp2raw_freebsd -I. main.cpp lib/md5.cpp lib/pbkdf2-sha1.cpp lib/pbkdf2-sha256.cpp encrypt.cpp log.cpp network.cpp common.cpp connection.cpp misc.cpp fd_manager.cpp client.cpp server.cpp -lpthread lib/aes_faster_c/aes.cpp lib/aes_faster_c/wrapper.cpp my_ev.cpp -isystem libev "-lpcap" -std=c++11 -Wall -Wextra -Wno-unused-variable -Wno-unused-parameter -Wno-missing-field-initializers -lrt -ggdb -static -O2 In file included from main.cpp:1: common.h:52:10: fatal error: linux/filter.h: No such file or directory 52 | #include <linux/filter.h> | ^~~~~~~~~~~~~~~~ compilation terminated.

i spent too much time looking for linux/filter with no luck .

Looks like it's my bad, I broke the BSD compile in some commit. It might solves the problem, if you change this line in makefile:

freebsd:git_version
	${cc_local}   -o ${NAME}_$@        -I. ${SOURCES} ${PCAP} ${FLAGS} -lrt -ggdb -static -O2

to

freebsd:git_version
	${cc_local}   -o ${NAME}_$@        -I. ${SOURCES} ${PCAP} ${FLAGS} -lrt -ggdb -static -O2 ${MP}

At the moment I do not have a BSD machine in hand to test the change. Could you plz try if it works?

thanks ,

the previous error gone , but it's seems we have a link or reference issue

try to remove -static:

freebsd:git_version
	${cc_local}   -o ${NAME}_$@        -I. ${SOURCES} ${PCAP} ${FLAGS} -lrt -ggdb -O2 ${MP}

[amrahmades]

Thanks, I have an executable file now !!

I'm going to test and give you feedback.

Do not remove -static, without it you won't have a static binary. Add -libverbs and then it will compile ok. Then you could use static binary on older systems without libraries (sometimes it's very important with older pfsense installs).

${cc_local}   -o ${NAME}_$@        -I. ${SOURCES} ${PCAP} ${FLAGS} -lrt -ggdb -static -libverbs -O2 ${MP}

Thank you very much for this. Can somebod please modify the makefile for freebsd to include this? I was searching a lot to find this very useful post.

I can confirm that the compile works OK with this modification on 13.2-RELEASE-p1 FreeBSD 64bit.
