$ konanc -l "$(find node_modules -name uv.klib)" main.kt
where main.kt
might be
import datkt.uv.* // entire libuv API
import kotlinx.cinterop.* // exposes types needed for interop
fun main(args: Array<String>) {
if (0 != uv_init()) {
throw Error("Failed to initialize libuv")
}
}
Example
import kotlinx.cinterop.*
import datkt.uv.uv_init
import datkt.uv.randombytes_buf
import datkt.uv.randombytes_random
import datkt.uv.randombytes_uniform
fun main(args: Array<String>) {
val rc = uv_init()
if (0 != rc) {
throw Error("uv_init() != 0")

which will produce build/lib/uv.klib
. The library can be installed

by running make install
Static Library
libuv.a
, a static library that can be linked with konanc
can be
built from source.
$ make static
which will produce build/lib/libuv.a
