Please follow this tutorial to build and test WasmEdge in OpenWrt(x86_64) from source code.
Currently, we only support the runtime for the interpreter mode.
First, we need to obtain the source code of OpenWrt and install the relevant tools to compile OpenWrt. The following commands take Debian / Ubuntu system as an example. For commands to install OpenWrt compilation tools in other host systems, see Building OpenWrt System Settings.
$ git clone https://github.com/openwrt/openwrt $ sudo apt update $ sudo apt install build-essential ccache ecj fastjar file g++ gawk \ gettext git java-propose-classpath libelf-dev libncurses5-dev \ libncursesw5-dev libssl-dev python python2.7-dev python3 unzip wget \ python-distutils-extra python3-setuptools python3-dev rsync subversion \ swig time xsltproc zlib1g-dev
Then, obtain all the latest package definitions of OpenWrt and install the symlinks for all obtained packages.
cd openwrt ./scripts/feeds update -a ./scripts/feeds install -a
git clone https://github.com/WasmEdge/WasmEdge.git cd WasmEdge
Run the build script
build_for_openwrt.sh in WasmEdge source code, and input the path of the OpenWrt source code as parameter. This script will automatically add the WasmEdge into the packages list which will be built of OpenWrt, and build the OpenWrt firmware. The generated OpenWrt images are in the
When running the build script, the OpenWrt configuration interface will appear. In this interface, we need to set
Target System to x86,
Target Profile to Generic x86/64, and find
WasmEdge in the
Runtime column and check it . Once set up, the script automatically builds WasmEdge and compiles the OpenWrt system.
In order to verify the availability of WasmEdge, we use a VMware virtual machine to install the compiled OpenWrt image. Before creating a virtual machine, we need to use the
QEMU command to convert the OpenWrt image to vmdk format.
cd ~/openwrt/bin/targets/x86/64 sudo apt install qemu gunzip openwrt-x86-64-generic-squashfs-combined.img.gz qemu-img convert -f raw -O vmdk openwrt-x86-64-generic-squashfs-combined.img Openwrt.vmdk
After that, create a virtual machine in VMware and install the OpenWrt system.
After setting the IP address of OpenWrt according to the gateway of the host, use
scp to transfer the wasm file on the host to the OpenWrt system.
scp hello.wasm firstname.lastname@example.org:/ scp add.wasm email@example.com:/
$ wasmedge hello.wasm second state hello second state $ wasmedge --reactor add.wasm add 2 2 4
