Subject: Link time problems with libipq example code
Date: Fri, 20 Dec 2002 15:44:05 -0700	[thread overview]
Message-ID: <20021220224405.GB28191@securityfocus.com> (raw)

Hello,
I've been trying to compile the libipq example code in the libipq man page.

My kernel is 2.4.18, distributed by RedHat as 2.4.18-14. I made a symlink to the kernel source at /usr/src/linux.
I built ipchains 1.2.7a as follows:
make
su
make install-devel

I copied the code from the man page into a file called ipqtst.c and compiled:
gcc -I/usr/local/include -L/usr/local/lib -lipq -o ipqtst ipqtst.c
/tmp/ccGDqSOi.o: In function `die':
/tmp/ccGDqSOi.o(.text+0xf): undefined reference to `ipq_perror'
/tmp/ccGDqSOi.o(.text+0x1d): undefined reference to `ipq_destroy_handle'
/tmp/ccGDqSOi.o: In function `main':
/tmp/ccGDqSOi.o(.text+0x49): undefined reference to `ipq_create_handle'
/tmp/ccGDqSOi.o(.text+0x81): undefined reference to `ipq_set_mode'
/tmp/ccGDqSOi.o(.text+0xb8): undefined reference to `ipq_read'
/tmp/ccGDqSOi.o(.text+0xe4): undefined reference to `ipq_message_type'
/tmp/ccGDqSOi.o(.text+0x116): undefined reference to `ipq_get_msgerr'
/tmp/ccGDqSOi.o(.text+0x141): undefined reference to `ipq_get_packet'
/tmp/ccGDqSOi.o(.text+0x166): undefined reference to `ipq_set_verdict'
collect2: ld returned 1 exit status

I get the same errors when I compile statically:
gcc -static -I/usr/local/include -L/usr/local/lib -lipq -o ipqtst ipqtst.c

Is libipq not the right thing to link against? Am I doing something else wrong (did I build ipchains incorrectly?)
