+== Using Debian / Raspbian libraries ==
+
+Choose a directory to store Raspbian packages, for instance `$RASPI_SDK_ROOT/chroot`. You can then use `debootstrap` to install packages to it, but if you have a multiarch-enabled system you can use this poor man's shell script:
+
+{{{
+#!sh
+raspi-install () {
+    for pkg in "$@"
+    do
+        apt-get download "$pkg":armhf \
+         && dpkg-deb -x "$pkg"_*.deb $RASPI_SDK_ROOT/chroot \
+         && rm -f "$pkg"_*_armhf.deb
+    done
+}
+}}}
+
+Then for ''eg.'' SDL:
+
+{{{
+#!sh
+raspi-install libsdl1.2debian libsdl1.2-dev
+}}}
+
+Then add the following to `CPPFLAGS` in the configure line:
+
+{{{
+#!sh
+-I$RASPI_SDK_ROOT/root/usr/include
+}}}
+
+And the following to `LDFLAGS`:
+
+{{{
+#!sh
+-L$RASPI_SDK_ROOT/chroot/lib/arm-linux-gnueabihf
+-Wl,-rpath-link -Wl,$RASPI_SDK_ROOT/chroot/lib/arm-linux-gnueabihf
+-L$RASPI_SDK_ROOT/chroot/usr/lib/arm-linux-gnueabihf

+-Wl,--unresolved-symbols=ignore-in-shared-libs
