Crate shaderc_sys

Shaderc system library FFI, building, and linking

This crate contains the lower-level C interface for the Shaderc library. For the higher-level Rust-friendly interface, please see the shaderc crate.

The Shaderc library provides an API for compiling GLSL/HLSL source code to SPIRV modules. It has been shipping in the Android NDK since version r12b.

This crate contains Rust FFI inteface to the Shaderc library. It also handles system library detection and building from source if no system library installed via build.rs.

The order of preference in which the build script will attempt to obtain Shaderc can be controlled by several options:

1. The option --features build-from-source will prevent automatic library detection and force building from source.
2. If the SHADERC_LIB_DIR environment variable is set to /path/to/shaderc/libs/, it will take precedence and libshaderc_combined.a (and the glslang and SPIRV libraries on Linux) will be searched in the /path/to/shaderc/libs/ directory.
3. On Linux, /usr/lib/ will be automatically searched for system libraries if none of the above were given.
4. If no other option was set or succeeded, shaderc-sys will fall back to checking out and compiling a copy of Shaderc. This procedure is quite slow.

The build script also tries to check whether Ninja is available on PATH. Ninja is required to build with Visual Studio because MSBuild does not support paths longer than MAX_PATH. On other platforms, Ninja is optional but is generally faster than the default build tool.
