Bolt is a gradle plugin that consumes static libraries for use in Kotlin Native projects. Its purpose is to keep the native source sets and toolchains out of Kotlin Multiplatform projects by downloading precompiled artifacts.

Usage

bolt {
    library = "liblinmem"
    url = "Url for static libraries"
}

Bolt works by convention, given a url it will look at the multiplatform targets you have enabled and expect to find a header and a specific archive/s. Archives can be zip or tar.

Kotlin Native Target	LLVM Target Triple
macosArm64()	aarch64-apple-darwin
macosX64()	x86_64-apple-darwin
iosArm64()	aarch64-apple-ios
iosSimulatorArm64()	aarch64-apple-ios-sim
iosX64()	x86_64-apple-ios
linuxArm64()	aarch64-unknown-linux-gnu
linuxX64()	x86_64-unknown-linux-gnu
mingwX64()	x86_64-pc-windows-gnu

For example if you have the following configuration:

bolt {
    library = "libfoo"
    url = "https://bar.com/0.1/"
}

kotlin {
    iosArm64()
    linuxArm64()
}

Then the plugin will look for

libfoo.h
libfoo-aarch64-apple-ios-sim.a.[zip/tar]
libfoo-aarch64-unknown-linux-gnu.a.[zip/tar]

Archives should contain one file, the static library itself i.e libfoo.a

Provided all the above is all correct then bolt will configure cinterop bindings such that you can now import libfoo
