The easiest way to start is to use [Wasienv](https://github.com/wasienv/wasienv).
Create `hello.c`:
```c
#include <stdio.h>
int main()
{
printf("Hello, %s!\n", "world");
return 0;
}
```
```sh
$ wasicc -O3 -Wl,--stack-first hello.c -o hello.wasm
$ wasm3 hello.wasm
Hello, world!
```
### C++ WASI app
### C/C++ WASI app
Create `hello.cpp`:
```cpp
#include <iostream>
int main()
{
std::cout << "Hello World!" << std::endl;
int main() {
std::cout << "Hello, world!" << std::endl;
return 0;
}
```
Or `hello.c`:
```c
#include <stdio.h>
int main() {
printf("Hello, %s!\n", "world");
return 0;
}
```
```sh
$ wasic++ -O3 -Wl,--stack-first hello.cpp -o hello.wasm
$ wasic++ -O3 hello.cpp -o hello.wasm
$ wasicc -O3 hello.c -o hello.wasm
$ wasm3 hello.wasm
Hello World!
```
Limitations:
- `setjmp/longjmp` and `C++ exceptions` are not available
- no support for `threads` and `atomics`
- no support for `dynamic libraries`
