Common Kotlin packages with support for linux_arm32_hfp, linux_arm64 and Android native.
This repo is serving two purposes at the moment. One is for tweaks of popular kotlin multiplatform packages for android native and linuxArm64, linuxArm32Hfp support. That you'll find in the repos folder.
The other is a complimentary plugin for cross-compiling native libraries for kotlin multiplatform.
Precompiled versions will be published at mavenCentral()
under my repository.
They might take a while to get there so pre-releases can be found
in the sonatype staging section
So you don't need to download this project and compile it, unless you want to.
To use them in your projects just add:
repositories {
// for the pre releases
maven("https://s01.oss.sonatype.org/content/groups/staging/")
// for the final releases
mavenCentral()
}
//and change "org.jetbrains.kotlinx" to "org.danbrough.kotlinx"
dependencies {
implementation("org.danbrough.kotlinx:kotlinx-coroutines-core:1.6.4")
implementation("org.danbrough.kotlinx:kotlinx-serialization-core:1.5.0")
// ..etc
}The tweaked repos will be git submodules under the repos folder.
So you can clone those, compare with upstream, roll your own.
Due to the need for absolute hard-coded paths in cinterop def files this repo will need to be
checked out at /usr/local/kotlinxtras
for building custom packages.
You can also use the "consumer" plugin from this project to automatically download precompiled
binaries to link against.
See the sqlite,curl_standalone,sqldelight in the demos folder for example.
The plugin is used for cross-compiling kotlin multiplatform projects with native library support. There are demos in the demos folder but it looks something like this:
const val XTRAS_OPENSSL_EXTN_NAME = "xtrasOpenssl"
open class OpenSSLBinaryExtension(project: Project) : LibraryExtension(project, "openssl")
class OpenSSLPlugin : Plugin<Project> {
override fun apply(project: Project) {
project.registerLibraryExtension(XTRAS_OPENSSL_EXTN_NAME, OpenSSLBinaryExtension::class.java) {
version = "1_1_1s"
git("https://github.com/danbrough/openssl.git", "02e6fd7998830218909cbc484ca054c5916fdc59")
configure { target ->
outputs.file(workingDir.resolve("Makefile"))
val args = mutableListOf(
"./Configure",
target.opensslPlatform,
"no-tests",
"threads",
"--prefix=${prefixDir(target)}"
)
if (target.family == Family.ANDROID) args += "-D__ANDROID_API__=21"
else if (target.family == Family.MINGW) args += "--cross-compile-prefix=${target.hostTriplet}-"
commandLine(args)
}
build { target ->
commandLine(binaryConfiguration.makeBinary, "install_sw")
}
cinterops {
headers = """
#staticLibraries = libcrypto.a libssl.a
headers = openssl/ssl.h openssl/err.h openssl/bio.h openssl/evp.h
linkerOpts.linux = -ldl -lc -lm -lssl -lcrypto
linkerOpts.android = -ldl -lc -lm -lssl -lcrypto
linkerOpts.macos = -ldl -lc -lm -lssl -lcrypto
linkerOpts.mingw = -lm -lssl -lcrypto
compilerOpts.android = -D__ANDROID_API__=21
compilerOpts = -Wno-macro-redefined -Wno-deprecated-declarations -Wno-incompatible-pointer-types-discards-qualifiers
#compilerOpts = -static
""".trimIndent()
}
}
}
}That creates a plugin that allows you to automatically download openSSL sources, cross compile them and build cinterop bindings for kotlin. You can also download precompiled binaries from maven.
In the case of curl,openssl,iconv,sqlite (at present) you don't need to write these yourself as they are provided, (with precompiled binaries for linuxArm32Hfp,linuuxArm64, linuxX64, macosX64,macosArm64,androidNativeX86 .. and the rest ..)
But as you can see, writing your own for projects using the "./configure, make install" logic isn't too hard.
