coral-media/ext-openblas
========================

[](#coral-mediaext-openblas)

`coral-media/ext-openblas` is a PHP extension scaffold for OpenBLAS using system OpenBLAS libraries.

Status
------

[](#status)

- PIE metadata configured
- Build config wired for `--with-openblas` (system OpenBLAS) on Unix and Windows
- Initial function exposed: `openblas_get_config()`
- Minimal PHPT tests included

System Requirements
-------------------

[](#system-requirements)

### Unix/Linux

[](#unixlinux)

- PHP development toolchain: `phpize`, `php-config`, C compiler, `make`
- OpenBLAS development files available via `pkg-config`
- Typical Debian/Ubuntu packages:
    - `libopenblas-dev`
    - `pkg-config`

### Windows

[](#windows)

- Visual Studio C/C++ build tools (used by `phpize`/`nmake` flow)
- OpenBLAS headers and import library installed (for example via `vcpkg`)
- Runtime `openblas.dll` available in `PATH` for tests/runtime

Install (PIE)
-------------

[](#install-pie)

```
pie install --with-openblas
```

Build From Source
-----------------

[](#build-from-source)

```
phpize
./configure --with-openblas
make -j"$(nproc)"
make test
```
