lightvgl-sys

Rust raw bindings for the LVGL C library.

Usage

Build requires the following environment variables to be set:

• DEP_LV_CONFIG_PATH: Path to the directory containing the lv_conf.h header file used for configuration of the LVGL library.

It is easier to store them in .cargo/config.toml then rust-analyzer will also pick them up.

[env]
DEP_LV_CONFIG_PATH = { relative = true, value = "." }

Alternatively, it can be added before cargo commands:

DEP_LV_CONFIG_PATH=`pwd` cargo build

Optional configuration

You might as well need to set one or more of these env variables, especially when cross-compiling:

• BINDGEN_EXTRA_CLANG_ARGS: Extra clang arguments to be passed to bindgen
• LV_COMPILE_ARGS: Extra arguments to be passed both to bindgen and to the C compiler
• CROSS_COMPILE: Target triple when cross-compiling
• LIBCLANG_PATH: Custom libclang.so location
