Hi Gopi,
I'm now rather confused. Are you still working on getting guile installed? Everything below seems to be part of libgraph, which is a completely separate animal from guile. On the guile-user mailing list, we might be able to help you install guile (no guarantees, of course), but any other packages are definitely outside of our realm of expertise. Please restrict posts to this mailing list to those dealing with guile in some way. For help installing libgraph, I suggest you seek a mailing list, newsgroup, or forum related specifically to libgraph, or perhaps to FreeBSD in general.

Also, if you have managed to fix or workaround any of the errors you have previously described, we would greatly appreciate it if you could explain in as much detail as possible exactly what you did that made the errors go away. That way, we can fix things, so that anyone else who wants to run guile 1.8 on FreeBSD won't have these troubles. So please tell us as much as you can remember of what you've done to make things work.
Regards,
Jon

Hi Jon
Sorry for the late reply.I was busy with something else, so was not able to mail you.For that guile-config i will let you know in my next mail definitely.My friend is on leave.Regarding make errors, now i dont get any errors,my make command says "Makefile", line 781: warning: duplicate script for target "libgraph.pc" ignored
make all-recursive
"Makefile", line 781: warning: duplicate script for target "libgraph.pc" ignored Making all in doc
Making all in man
"Makefile", line 781: warning: duplicate script for target "libgraph.pc" ignored # I dont know whether make is complete or not.I think its incomplete.But make install command gives without error, it ends with libraries have been installed in :
/usr/local/lib
If you ever happen to want to link against installed libraries in a given directory, LIBDIR, you must either use libtool, and specify the full pathname of the library, or use the '-LIBDIR' flag during linking and do at least one of the following:
-add LIBDIR to the LD_LIBRARY_PATH  environment variable during execution
-add LIBDIR to the LD_RUN_PATH enivronment variable during linking
-use the -WI --rpath -WI --rpath LIBDIR linker flag
see any operating system documentation about shared libraries for more information ,such as the ld(1) and ld.so(8) manual pages

Now can u tell me whether libgraph is completely installed or not? regards
gopi

    Hi Gopi,
    What output did make give before and after the error (just several
    lines, at LEAST including the call to the compiler or the linker
    which
    caused this error)? What are the values of some of your shell
    variables, such as LD_LIBRARY_PATH, and the contents of the
    /etc/ld.so.conf file? Have you run ldconfig as root since making any
    changes to libraries? What compiler and linker are you using, name
    and
    version?

    It seems as though the linker is not finding the file containing the
    main function (from the guile source, not the system libs), but we
    cannot tell for sure without seeing the output from make, and the
    various other things I listed here.
    Regards,
    Jon
