gd is one of those libraries that can be compiled a number of different
ways, depending upon what is installed on the system. If you aren't
careful, installing gd can force you to bring in much of X11 (gd likes to
use libraries such as freetype that are part of or integrally linked into
X11). Sometimes this means that compiling gd from source is your best bet.
Other times, such as Gentoo's portage, there are special parameters so you
don't use the X11 stuff.
With me so far?
OK...
When reading config.log, basically you just have to read the output ...
anything that SOUNDS like an error message is probably an error message:
/usr/local/lib/libgd.so.2.0: undefined reference to `libiconv_open'
/usr/local/lib/libgd.so.2.0: undefined reference to `libiconv_close'
/usr/local/lib/libgd.so.2.0: undefined reference to `libiconv'
Remember the pattern -- libxxxxx is a -lxxxxx in the compile/link.
So you probably need to add -liconv to your compile command.
Now if you search the mailing list back traffic for iconv, you will find
it's a slippery bugger. Sometimes it's required and other times it breaks
things.
So what do you do? Well, there's a specific place in ntop for OS specific
stuff... and I put a lot of work into making it pretty flexible. It's the
configureextra subdirectory.
Look there and you'll see OS specific, OS/distro and even OS/distro/release
files... Look in there and you will usually find a model for pretty much
anything.
grep in there for iconv and you'll see how we solved it for Solaris.
That's probably a good start for openbsd. Rip the iconv lines from
configureextra/solaris8:
$ cat solaris8
#!/bin/sh
echo " Setting Solaris 8 specific flag values"
LDFLAGS="-L/usr/local/lib -lnsl -lsocket ${LDFLAGS}"
. configureextra/functions
# Test for GNU libiconv (e.g. SunFreeware)
test_library iconv iconv_open
and drop them into the openbsd file:
$ cat openbsd
#!/bin/sh
echo " Setting OpenBSD specific flag values"
SO_VERSION_PATCH=.0.0
# This is probably not right, but we can't seem to settle on what IS
right...
MAKE_SHARED_LIBRARY_PARM="-shared"
i.e.
====================================================================
#!/bin/sh
echo " Setting OpenBSD specific flag values"
SO_VERSION_PATCH=.0.0
# This is probably not right, but we can't seem to settle on what IS
right...
MAKE_SHARED_LIBRARY_PARM="-shared"
. configureextra/functions
# Test for GNU libiconv (e.g. SunFreeware)
test_library iconv iconv_open
