I know that perhaps no one can help, since it is with a specific, nonstandard (?), program, but I think this may have to do with something more system-generic. I hope.
I am trying to install gtkmm (so that I can install another program), and on the web site it said that it required libsigc++. So I downloaded it, and installed libsigc++, no problems, error messages, nothing. I installed it by compiling and then make install-ing.
when I ./configure gtkmm, it does find a version of libsigc++ that is compatable (or, at least, it is above the required version level and there were no mentions of bug about it on the site), but it tells me that libsigc++ is not sane.
I have no idea what this means. however, I followed the instructions : "Most likely this means that you have not placed /usr/local/lib path in your library config file and urn ldconfig."
and so, after hunting around and asking a couple of people, I find that my library config file is /etc/ld.so.conf. I add this path, /usr/local/lib, to the bottom there, and run ldconfig, as root naturally. still, when trying to compile gtkmm, I get the exact same error message as if nothing has happened.
to be thourough, I tried to install libsigc++ again after having put that path int he library config file, but that did not help.
what am I doing wrong?
if indeed no one can help me: should I post this question on the gtkmm or the libsigc++ sites?
