+=== Supporting multiple architectures (armv6 and armv7) ===
+
+You need to compile separately for each architecture. For armv7, you need to compile using the flags:
+
+{{{
+export CFLAGS += -march=armv7 -mcpu=arm1176jzf-s -mcpu=cortex-a8
+export LDFLAGS += -march=armv7 -mcpu=arm1176jzf-s -mcpu=cortex-a8
+}}}
+
+For armv6, you need to compile using the flags:
+
+{{{
+export CFLAGS += -march=armv6 -mcpu=arm1176jzf-s
+export LDFLAGS += -march=armv6 -mcpu=arm1176jzf-s
+}}}
+
+Then you need to combine the resulting libraries using the '''{{{lipo}}}''' command. For example:
+
+{{{
+lipo -arch armv6 lib/armv6/libpjlib.a -arch armv7 lib/armv7/libpjlib.a -create -output lib/libpjlib.a
+}}}
+
+Another way to build a universal binary (for reference on how to build it on MacOS X, please see [https://trac.pjsip.org/repos/wiki/FAQ#osx-universal the FAQ here]) is to use '''{{{llvm-gcc}}}''' compiler provided in the iPhone SDK. For reference, please see [http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2011-June/013052.html this discussion] in pjsip mailing list.
