tblis-src: Crate for TBLIS Source Code

To use crate tblis-ffi in rust, you may need to perform some configuration to properly link libtblis.so into your own program.

Link library tblis with cargo crate tblis-src

You can link library tblis by cargo crate tblis-src. You can use crago feature build_from_source to automatically build TBLIS with default configuration.

Crate features

• build_from_source: This will use CMake (cmake > 3.23, c++20 standard), and use the code from git submodule to compile tblis. Though this option can be developer-friendly (you do not need to perform any other configurations to make program compile and run by cargo), build_from_source does not provide customized compilation.

  CMake configurable variables (can be defined as environment variables):

  • TBLIS_SRC: Git repository source directory or URL. All git submodules (marray, blis, tci) should be properly downloaded.
  • TBLIS_VER: Git repository version (branch or tag). Default to be develop.

• static: This will link static libary instead of dynamic one. Please note that static linking may require additional dynamic library linking, which should be configured manually by developer in build.rs or environment variables RUSTFLAGS. Static linking can be difficult when searching symbols, and we recommend dynamic linking in most cases.

Link library tblis manually

By this way, you can directly use cargo crate tblis-ffi, without using tblis-src.

It is recommended to link libtblis.so by dynamic linking. Making sure your library is in environment variable LD_LIBRARY_PATH, then

// build.rs
println!("cargo:rustc-link-lib=tblis");
