# Prepare WASM building environments # Prepare WASM building environments
WASI-SDK version 8.0+ is the major tool supported by WAMR to build WASM applications. There are some other WASM compilers such as the standard clang compiler and Emscripten might also work [here](./other_wasm_compilers.md). For C and C++, WASI-SDK version 12.0+ is the major tool supported by WAMR to build WASM applications. Also we can use [Emscripten SDK (EMSDK)](https://github.com/emscripten-core/emsdk), but it is not recommended. And there are some other compilers such as the standard clang compiler, which might also work [here](./other_wasm_compilers.md).
Install WASI SDK: Download the [wasi-sdk](https://github.com/CraneStation/wasi-sdk/releases) and extract the archive to default path `/opt/wasi-sdk` To install WASI SDK, please download the [wasi-sdk release](https://github.com/CraneStation/wasi-sdk/releases) and extract the archive to default path `/opt/wasi-sdk`.
For [AssemblyScript](https://github.com/AssemblyScript/assemblyscript), please refer to [AssemblyScript quick start](https://www.assemblyscript.org/quick-start.html) and [AssemblyScript compiler](https://www.assemblyscript.org/compiler.html#command-line-options) for how to install `asc` compiler and build WASM applications.
For Rust, please firstly ref to [Install Rust and Cargo](https://doc.rust-lang.org/cargo/getting-started/installation.html) to install cargo, rustc and rustup, by default they are installed under ~/.cargo/bin, and then run `rustup target add wasm32-wasi` to install wasm32-wasi target for Rust toolchain. To build WASM applications, we can run `cargo build --target wasm32-wasi`, the output files are under `target/wasm32-wasi`.

Note that it is wasi mode, so libc-wasi should be enabled by runtime embedder or iwasm (with cmake -DWAMR_BUILD_LIBC_WASI=1, enabled by iwasm in Linux by default), and normally no need to export main function, by default _start function is executed by iwasm.
## 2. How to reduce the footprint?
Firstly if libc-builtin (-nostdlib) mode meets the requirements, e.g. there are no file io operations in wasm app, we should build the wasm app with -nostdlib option as possible as we can, since the compiler doesn't build the libc source code into wasm bytecodes, which greatly reduces the binary size.
### (1) Methods to reduce the libc-builtin (-nostdlib) mode footprint
- export \_\_heap_base global and \_\_data_end global
```bash
-Wl,--export=__heap_base -Wl,--export=__data_end
```
If the two globals are exported, and there are no memory.grow and memory.size opcodes (normally nostdlib mode doesn't introduce these opcodes since the libc malloc function isn't built into wasm bytecode), WAMR runtime will truncate the linear memory at the place of \__heap_base and append app heap to the end, so we don't need to allocate the memory specified by `-Wl,--initial-memory=n` which must be at least 64 KB. This is helpful for some embedded devices whose memory resource might be limited.
- reduce auxiliary stack size
The auxiliary stack is an area of linear memory, normally the size is 64 KB by default which might be a little large for embedded devices and actually partly used, we can use `-z stack-size=n` to set its size.
- use -O3 and -Wl,--strip-all
- reduce app heap size when running iwasm
We can pass `--heap-size=n` option to set the maximum app heap size for iwasm, by default it is 16 KB. For the runtime embedder, we can set the `uint32_t heap_size` argument when calling API ` wasm_runtime_instantiate`.
- reduce wasm operand stack size when running iwasm
WebAssembly is a binary instruction format for a stack-based virtual machine, which requires a stack to execute the bytecodes. We can pass `--stack-size=n` option to set the maximum stack size for iwasm, by default it is 16 KB. For the runtime embedder, we can set the `uint32_t stack_size` argument when calling API ` wasm_runtime_instantiate` and `wasm_runtime_create_exec_env`.
- decrease block_addr_cache size for classic interpreter
The block_addr_cache is an hash cache to store the else/end addresses for WebAssembly blocks (BLOCK/IF/LOOP) to speed up address lookup. This is only available in classic interpreter. We can set it by define macro `-DBLOCK_ADDR_CACHE_SIZE=n`, e.g. add `add_defintion (-DBLOCK_ADDR_CACHE_SIZE=n)` in CMakeLists.txt, by default it is 64, and total block_addr_cache size is 3072 bytes in 64-bit platform and 1536 bytes in 32-bit platform.
### (2) Methods to reduce the libc-wasi (without -nostdlib) mode footprint
Most of the above methods are also available for libc-wasi mode, besides them, we can export malloc and free functions with `-Wl,--export=malloc -Wl,--export=free` option, so WAMR runtime will disable its app heap and call the malloc/free function exported to allocate/free the memory from/to the heap space managed by libc.
## 3. Build wasm app with pthread support
Please ref to [pthread library](./pthread_library.md) for more details.
## 4. Build wasm app with SIMD support
Normally we should install emsdk and use its SSE header files, please ref to workload samples, e.g. [bwa CMakeLists.txt](../samples/workload/bwa/CMakeLists.txt) and [wasm-av1 CMakeLists.txt](../samples/workload/wasm-av1/CMakeLists.txt) for more details.
# Build WASM applications with emsdk
## 1. Install emsdk
Assuming you are using Linux, you may install emcc and em++ from Emscripten EMSDK following the steps below:
```
git clone https://github.com/emscripten-core/emsdk.git
cd emsdk
./emsdk install latest
./emsdk activate latest
# And then source the emsdk_env.sh script before build wasm app
source emsdk_env.sh (or add it to ~/.bashrc if you don't want to run it each time)
```
The Emscripten website provides other installation methods beyond Linux.
## 2. emsdk options
To build the wasm C source code into wasm binary, we can use the following command:
```bash
EMCC_ONLY_FORCED_STDLIBS=1 emcc -O3 -s STANDALONE_WASM=1 \
-o test.wasm test.c \
-s TOTAL_STACK=4096 -s TOTAL_MEMORY=65536 \
-s "EXPORTED_FUNCTIONS=['_main']" \
-s ERROR_ON_UNDEFINED_SYMBOLS=0
```
There are some useful options:
- **EMCC_ONLY_FORCED_STDLIBS=1** whether to link libc library into the output binary or not, similar to `-nostdlib` option of wasi-sdk clang. If specified, then no libc library is linked and the **libc-builtin** library of WAMR must be built to run the wasm app, otherwise, the **libc-wasi** library must be built. You can specify **-DWAMR_BUILD_LIBC_BUILTIN=1** or **-DWAMR_BUILD_LIBC_WASI=1** for cmake to build WAMR with libc-builtin support or libc-wasi support.
The emsdk's wasi implementation is incomplete, e.g. open a file might just return fail, so it is strongly not recommended to use this mode, especially when there are file io operations in wasm app, please use wasi-sdk instead.
- **-s STANDALONE_WASM=1** build wasm app in standalone mode (non-web mode), if the output file has suffix ".wasm", then only wasm file is generated (without html file and JavaScript file).
- **-s TOTAL_STACK=\<value\>** the auxiliary stack size, same as `-z stack-size=\<value\>` of wasi-sdk
- **-s TOTAL_MEMORY=\<value\>** or **-s INITIAL_MEORY=\<value\>** the initial linear memory size
- **-s MAXIMUM_MEMORY=\<value\>** the maximum linear memory size, only take effect if **-s ALLOW_MEMORY_GROWTH=1** is set
- **-s ALLOW_MEMORY_GROWTH=1/0** whether the linear memory is allowed to grow or not
- **-s "EXPORTED_FUNCTIONS=['func name1', 'func name2']"** to export functions
- **-s ERROR_ON_UNDEFINED_SYMBOLS=0** disable the errors when there are undefined symbols
For more options, please ref to <EMSDK_DIR>/upstream/emscripten/src/settings.js, or [Emscripten document](https://emscripten.org/docs/compiling/Building-Projects.html).
