M:
As a first step, y'all need to TRY AND READ the output of config.log.
Don't be afraid, it's pretty basic. If you get an error message you don't
understand, then ask, but FIRST, try reading it yourself...
In this, Stanley was 100% right - he knew where to look (config.log), how to
isolate it to the right section. But hey, he's a FreeBSD guy, so you can't
expect him to know his Penguins from his Polar Bears... (S: Right Church,
wrong pew. Couple of good tries but no cigar.)
FWIW, nm works only if the executable isn't 'stripped'. The other tool is
objdump:
$ objdump /usr/lib/libpcap.so -T | grep pcap_open_live
00002d10 g DF .text 000003f5 Base pcap_open_live
All: In reading config.log, look for the failing thing and then for the
lines around it...
See the error message? Sure you do. THAT is what you need to chase down...
/usr/bin/ld: cannot find -lz
Remember w/ -l, there's an invisible lib prefix, so you're looking for
libz.so and need to tell ntop how to find it via
./configure's --with-zlib-lib=
