Hi guys,
I'm trying to cross-compile iftop while using a custom install location of libpcap. So far, I am unsuccessful with going past a configure script error...
First of all I have libpcap installed here:
/usr/src/DVG1000_V1.1.01.04_WN_src/apps# ls libpcap-1.2.0/pcap-install/ bin include lib share
root@builder:/usr/src/DVG1000_V1.1.01.04_WN_src/apps# ls libpcap-1.2.0/pcap-install/include/ pcap pcap-bpf.h pcap.h pcap-namedb.h root@builder:/usr/src/DVG1000_V1.1.01.04_WN_src/apps# ls libpcap-1.2.0/pcap-install/include/pcap bluetooth.h bpf.h ipnet.h namedb.h pcap.h sll.h usb.h vlan.h
root@builder:/usr/src/DVG1000_V1.1.01.04_WN_src/apps# ls libpcap-1.2.0/pcap-install/lib/ libpcap.a libpcap.so libpcap.so.1 libpcap.so.1.2.0
# CC=mips-linux-uclibc-cc ac_cv_linux_vers=2 ac_cv_func_malloc_0_nonnull=yes ./configure --host=mips-linux --with-libpcap=/usr/src/DVG1000_V1.1.01.04_WN_src/apps/libpcap-1.2.0/pcap-install
checking gethostbyaddr_r usability... can't test because we are cross-compiling checking where to find pcap.h... /include checking for pcap_open_live in -lpcap... no configure: error: can't find libpcap You're not going to get very far without libpcap.
Looking at the ./configure --help => --with-libpcap=WHERE Where the libpcap packet-capture library is found. The pcap library should be installed in WHERE/lib, and the header file in either WHERE/include or WHERE/include/pcap.
I've already checked and the library files + header files really are in "WHERE"/lib and /include/pcap.... So what am I doing wrong ? Is there a way to convince the configure script to take a better look in there ?
Thanks, Mihai

Solved it. My fault... Iftop-0.17 but the cross-compiler was the problem. The one in the Netgear toolchain (what I was compiling for) when linking with libpcap (found this by compiling a libpcap basic example by hand) was trying to then locate the at_exit symbol in uclibc lib. The lib didn't have it => error. The configure script didn't output anything regarding this so it was quite confusing.
I rebuilt their compiler according to the real, existing uClibc and this worked.
Sorry for the trouble.
Thanks, Mihai
