+===== Cross-compiling for PPC on i386 (on MacOS 10.5) =====
+It is possible to cross-compile Macports and the MiniDisc software for PPC on an i386 host. This is very convenient as it dramatically speeds up building the software for PPC since the fastest PPC Macs are much slower than current Intel machines.
+First, install XCode and Macports as described above, but do not install Qt as it will be installed through Macports.
+After installing Macports, edit the //macports.conf// (in /opt/local/etc/macports) configuration file to set the build rchitecture to PPC:
+<code>
+build_arch                      ppc
+</code>
+Then, edit the portfile for libffi to fix a problem with cross-compilation. Type "port edit libffi" and add:
+<code>
+configure.args --build=powerpc-apple-darwin9.8.0 --with-gcc-arch=ppc
+</code>
+Other ports to be patched: //libmad//, //orc//.
+For //orc//, comment the first line shown here out (prepend the hash sign) and add the second one:
+<code>
+#configure.optflags-append -Xarch_i386 -O1
+configure.args --build=powerpc-apple-darwin9.8.0
+</code>
+For //libmad// and //fftw-3//, just add:
+<code>
+configure.args --build=powerpc-apple-darwin9.8.0
+</code>
+For //fftw-3//, comment out all lines containing references to "sse2".
+Finally, for //xorg-libXrandr//, add:
+<code>
+configure.ldflags -Wl,-headerpad_max_install_names
+</code>
+Now, install the dependencies as usual, but include //qt4-mac//:
+<code>
+sudo port install glib2 libmad git-core sox libgcrypt taglib libid3tag libusb-devel qt4-mac
+</code>
+Finally, edit the qmake project file of linux-minidisc, //md.pro// by adding the following two lines:
+<code>
+CONFIG += ppc
+CONFIG -= i386
+</code>
+Then, build as described above.
