# NXOS-SDK

## Prerequisite

* host c/c++ compiler. (gcc or clang)
* make
* cmake
* ninja (optional)

## Build from source

1. update the gitmodules

```shell
git submodule update --init --depth 1
```

2. build the clang, lld and llvm tools using the host c/c++ compiler.

```shell
make build-clang
```

3. build the baselib(libnxos, libxlibc), llvm runtimes(libc++, libc++abi, etc.) using the clang.

```shell
make build-runtimes-riscv64 # build the riscv64 target library.
make build-runtimes-x86     # build the x86 target library.
```

4. Install the clang, baselib and runtimes.

```shell
make build-clang                # install the clang,lld and llvm tools.
make install-runtimes-riscv64   # install the riscv64 target library.
make install-runtimes-x86       # install the x86 target library.
```

### Misc

**Available ARCHs: riscv64, x86**

Other goals:
* ```make``` or ```make help```: Show the help message.
* ```make distclan```: Delete all generated files in build directory.
* ```make clean-<ARCH>```: Clean the build for the arch.

Available Variables:
* ```PREFIX```: Set the install directory, default: ```/opt/nxos-sdk```.
* ```O```: Set the build directory, default: ```./build```.
* ```HOST_CC```: Set the host c compiler to build clang.
* ```HOST_CXX```: Set the host cxx compiler to build clang.
