error compiling nfqnl_test.c

error compiling nfqnl_test.c

[Frank Abel Cancio Bello]

Hi all!

A newbie question:
When I try to compile "nfqnl_test.c" putting on command line:

"gcc -Wall -o nfqnl_test nfqnl_test.c"

the following error occur:

"
/tmp/cc8hh7RL.o: In function `print_pkt':nfqnl_test.c:(.text+0x15): undefined 
reference to `nfq_get_msg_packet_hdr'

:nfqnl_test.c:(.text+0x3f4): undefined reference to `nfq_close'

"

What I must put a command line to compile the "nfqnl_test.c"

Salute

[snip errors]

you forgot to include required library symbols:

gcc -Wall -o nfqnl_test nfqnl_test.c -lnfnetlink -lnetfilter_queue

will do

Thanks Sebastien!

Now the problem is when I try to run the binary, when I put on command line:

./nfqnl_test

the following error happend:

./nfqnl_test: error while loading shared libraries: libnfnetlink.so.0: cannot 
open shared object file: No such file or directory

Nevertheless my box have theses files:
/usr/local/lib/libnfnetlink.so.0
/usr/local/lib/libnfnetlink.so.0.0.0

Beside, when I install the libnfnetlink ("./configure;make;make install") I 
get a binary of nfqnl_test.c into utils directory and when I run it all is 
fine.

  Try to run ldconfig
  If this fails ,try to edit /etc/ld.so.conf and add
  /usr/local/lib
  So run ldconfig again.

Add /usr/local/lib to ld.conf or LD_LIBRARY_PATH env variable.

[Frank Abel Cancio Bello]

Thanks very much!!!
I'm advancing... lol

I need modify the nfqnl_test.c, specifically  I need access to ip.h and the=
=20
icmp.h headers. So I add "#include <linux/ip.h>" to the beginning of the fi=
le=20
nfqnl_test.c.

and when I try to compile with

gcc -Wall -o nfqnl_test nfqnl_test.c -lnfnetlink -lnetfilter_queue

the following errors:

In file included from nfqnl_test.c:10:
/usr/include/linux/ip.h:93:2: error: #error "Endian problem - this didn't=20
happen"
=2E......

the second line say something funy... :)

somebody known how solve this problem?
