entirely possible...

okay a little clearer now:
        no matter what options, libsig++ is compiled...
        paragui2-config includes references to srcdir (and sigc++) also
                no matter what configure options are used

and yes libsigc++'s autogen.sh is missing in my tree...  I'll have to see
if I can fix that this evening...

oh, it's got it's own configure.in + Makefile.am - history from a much
further ago split, probably to make a distro easier.   I've been using the
testapps (and the mpeg plugin :) as test apps for development - and if
neither are created properly -- or if paragui2-config breaks -- something
is wrong.

*heh* I think I will.... :)

apologies for overreaction...  I've had stuff (elsewhere) dissappear
overnight before - I've taken to maintaining serious backups because of
that in the past but have tended not to lately due to lack of backup media
*sigh*.   Anyways, overreaction - my bad.

*heh* didn't think of that.  Right - signing up today :)

Right - I'm going to try and make more detailed logs of what I'm doing too :)

paragui2-config.in:
      echo $includes address@hidden@/paragui2 @PARAGUI_CFLAGS@

in configure.in:
internalsigc=no
AC_ARG_ENABLE(internalsigc,
        [  --enable-internalsigc enable internal LibSigC++ version],
        internalsigc=yes
)

if test x$internalsigc = xno; then

    PKG_CHECK_MODULES(SIGC, $PKG_SIGC >= $SIGC_VERSION)

else
    SIGC_CFLAGS="-I\$(srcdir)/../libsigc++/sigc++/config 
-I\$(srcdir)/../libsigc++"
    SIGC_LIBS="./libsigc++/sigc++/libsigc-1.2.la"
    SIGC_SUBDIR="libsigc++"
    LIBSIGC=""
fi
..
PARAGUI_CFLAGS="$STL_CFLAGS $SIGC_CFLAGS $FREETYPE_CFLAGS $SDL_CFLAGS 
$RTTI_FLAGS $EXTRA_FLAGS"
...
first of all - internalsigc should NEVER be true except on platforms that
don't have it.  debian these days is tending towards making it a core
component as it's required by a number of things....

check out the section starting with "dnl Figure out which math library to use"
for platform-checking...  although it doesn't handle the special case of
embedded platforms...

as a comment, this is the bit I found in the --cflags option of
paragui2-config:
    SIGC_CFLAGS="-I\$(srcdir)/../libsigc++/sigc++/config 
-I\$(srcdir)/../libsigc++"

My configure line:
../configure --enable-internalexpat --enable-internalphysfs \
--disable-internalsigc \
--prefix=/usr

(I build in a seperate directory... makes directory sizes smaller and easier
to find files... ALSO nice for eventual cross-compiling :)
and the resulting echo:
/home/teunis/apps/paragui/i386-linux-gnu/paragui2-config: line 1: srcdir:
command not found
/home/teunis/apps/paragui/i386-linux-gnu/paragui2-config: line 1: srcdir:
command not found
-I/usr/include/paragui2 -I/../libsigc++/sigc++/config -I/../libsigc++
-I/usr/include/freetype2 -I/usr/include/SDL -D_REENTRANT

hrm - thoughts?

Anyhoo, more awake now.
G'day, eh? :)
