Re: glibmm building and sigc++ problem

[Paul Davis <pjdavis engineering uiowa edu>]

TJ,

pkg-config sigc++-2.0 --libs
gives me
-lsigc-2.0

Which is right.

You should look in /usr/local/lib for libsigc-2.0 libraries.

Now, if you want to try something, you can reconfigure and install the 
libraries to /usr/lib and /usr/include

from "./configure --help" :
By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc.  You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.

so that would be:
./configure --prefix=/usr
./make
./make install

Try that out and see if it helps.  If you have everything built alread 
it shouldn't take very long to do.  Its not the best way to do things, 
but it shoudl work.
