(i have patched scons *only* to print more stuff, and SConstruct to
use -O0, wishing to down the build time)

So, i changed
env.Append(QT4_MOC=["-I/usr/include"])
for
env.Append(QT4_MOCFROMHFLAGS=["-I/usr/include"])
its okey now?

Take a look, without defining QTDIR

but the pkgconfig looks good (well, thanks to the network editor now i
know that pkg-config exists):

Well i thougt that pkg-config wasnt a dependency.


I have a few more questions ;)

1)
Take a look to the prefix's on *.pc

[san at abulafia src]$ cat /usr/lib/pkgconfig/clam_core.pc
name = clam_core
prefix = /home/san/clam/clean/pkg/usr
libdir = ${prefix}/lib
includedir = ${prefix}/include

Name: ${name}

of music audio signals

-I/usr/lib/sigc++-2.0/include -I/usr/include/glib-2.0

[san at abulafia src]$ cat /usr/lib/pkgconfig/clam_qtmonitors.pc
name = clam_qtmonitors
prefix = /home/san/clam/Ne/pkg
libdir = ${prefix}/lib
includedir = ${prefix}/include

Name: ${name}

they are wrong? I think they should say prefix = /usr, and that value
is taken from the  scons install --prefix=DIR
but because i am "doing the package"  and not using the "final" prefix.
How should i change them? In post install or what?

2)
How to tell NetworkEditor the correct path of example-data so when i
click in examples it opens directly that?
Now it is pointing to the pkgdir/usr/share instead of /usr/share/blah

I had read the sources of the debian packages, but still dont
understand! (well i dont have experience with debian)

thanks! and sory for the length
