more than numpy

Buildscripts to build numpy and other wheels for wasix. For convenience, this package already includes prebuilt versions of all the wheels and libraries.

Usage

The build script is controlled by the following environment variables:

• CC, CXX, AR, LD, RANLIB, etc... : The cross-compiler tools. These should all be normal clang tools, but target wasm32-wasix by default and use the wasix sysroot.
• WASIX_SYSROOT: The path to the wasix sysroot that is used by the toolchain. Libraries will get installed here when you run make install or when they are required to build a package.
• INSTALL_DIR: The path to the python library path. Wheels will get installed here when you run make install.
• WASMER: The path to the wasmer binary. You must have it registered to handle wasm files as binfmt_misc. You can do this with sudo $WASMER binfmt reregister.

The easiest way to setup all the environment variables is to activate the wasix-clang environment using source wasix-clang/activate.

Then you can run make all to build all wheels and libraries.

Notes

All built library packages should include a pkg-config file for each library.

Variables in pkg-config files

When building libs, we should make shour they include pkg-config files. The pkg config files should have their prefix set to /usr/local, exec_prefix set to ${prefix}, libdir set to ${exec_prefix}/lib/wasm32-wasi, and includedir set to ${prefix}/include. In some cases it might be acceptable to have exec_prefix hardcoded to the same value as prefix. In that case libdir should start with ${prefix} instead of ${exec_prefix}.
