+Cross Compiling DPDK using Meson
+--------------------------------
+
+Meson depends on pkgconfig to find the dependencies.
+The package ``pkg-config-aarch64-linux-gnu`` is required for aarch64.
+To install it in Ubuntu::
+
+   sudo apt-get install pkg-config-aarch64-linux-gnu
+
+To cross-compile DPDK on a desired target machine we can use the following
+command::
+
+	meson cross-build --cross-file <target_machine_configuration>
+	ninja -C cross-build
+
+For example if the target machine is arm64 we can use the following
+command::
+
+	meson arm64-build --cross-file config/arm/arm64_armv8_linux_gcc
+	ninja -C arm64-build
+
+Configure and Cross Compile DPDK using Make
+-------------------------------------------
 To configure a build, choose one of the target configurations, like arm64-dpaa-linux-gcc and arm64-thunderx-linux-gcc.
