1. How to build iwasm in Linux

cd products/linux/
mkdir build && cd build
cmake .. && make

2. How to build iwasm in Zephyr system
(1) clone zephyr source code

git clone https://github.com/zephyrproject-rtos/zephyr.git

(2) copy /products/zephyr/simple directory to zephry/samples/

cd zephyr/samples/
cp -a /products/zephyr/simple simple
cd simple

(3) create a link to and rename it to iwasm

ln -s iwasm

(4) create a link to and rename it to shared-lib

ln -s shared-lib

(5) build source code

mkdir build && cd build
source ../../../zephyr-env.sh
cmake -GNinja -DBOARD=qemu_x86 ..
ninja

(6) run simple

ninja run

3. How to build iwasm in AliOS-Things platform
(1) clone AliOS-Things source code

git clone https://github.com/alibaba/AliOS-Things.git

(2) copy /products/alios-things directory to AliOS-Things/middleware,
and rename it as iwasm

cp -a /products/alios-things middleware/iwasm

(3) create a link to in middleware/iwasm/ and rename it to iwasm

ln -s middleware/iwasm/iwasm

(4) create a link to in middleware/iwasm/ and rename it to shared-lib

ln -s middle/iwasm/shared-lib

(5) modify sample source code of AliOS-Things to call iwasm_init() function

modify file app/example/helloworld/helloworld.c, in the beginning of
function application_start(), add:

bool iwasm_init(void);
iwasm_init();

modify file app/example/helloworld/helloworld.mk, change
$(NAME)_COMPONENTS := yloop cli
to
$(NAME)_COMPONENTS := yloop cli iwasm

(6) build source code

aos make helloworld@linuxhost

(7) run source code
./out/helloworld@linuxhost/binary/helloworld@linuxhost.elf
