[sigc] Compiling libsigc++ on Linux using mingw

[Tim Mazid <timmazid hotmail com>]

Hi list,

I am attempting to compile libsigc++ on Linux using mingw, as it is a
prerequisite of libgtkmm.

I grabbed the mingw cross compiling environment with "wget
http://download.savannah.nongnu.org/releases/mingw-cross-env/mingw-cross-env-2.15.tar.gz";,
from http://www.nongnu.org/mingw-cross-env, and ran "make gcc boost gtk".
This operation completed successfully.

I then downloaded libgtkmm-2.22.2 from the GNOME ftp site, and ran a
"./autogen.sh --host=i686-pc-mingw32", which yielded "configure: error:
Package requirements (sigc++-2.0 >= 2.0 glib-2.0 >= 2.21.1
gobject-2.0 >= 2.21.1 gmodule-2.0 >= 2.21.1) were not met:

No package 'sigc++-2.0' found"

So, I got libsigc++-2.2.8 also from the GNOME ftp site, and ran the same
autogen command, which completed successfully.  However, when I tried to
"make", it gives the following:

"make  all-recursive
make[1]: Entering directory `/home/tim/projects/libsigc++-2.2.8'

Apologies if I seem grumpy or frank, but I've been trying to set up an adequate
cross compiling environment for almost a fortnight now, and haven't gotten
very far yet.
