ndk-pkg

A package builder/manager for Android NDK to build projects written in C, C++, Rust, Golang, etc.

Caveats

Please read these caveats carefully before starting to use this software.

This software is being actively developed. It's in beta stage and may not be stable. Some features are subject to change without notice.
Please do NOT place your own files under ~/.ndk-pkg directory, as ndk-pkg will change files under ~/.ndk-pkg directory without notice.
Please do NOT run ndk-pkg command in parallel so as not to generate dirty data.

Platforms that this software can run on

HostOS	HostArch	SubSystem	recommended	fully tested	fully supported
✶	`x86_64`	Docker	✔︎	✔︎	✔︎
GNU/Linux	`x86_64`		✔︎	✔︎	✔︎
Windows	`x86_64`	WSL
macOS	`x86_64` `arm64`			✔︎

Notes :

This software can NOT run on Cygwin and MSYS2 due to a cmake error: CMake: Builds hosted on 'CYGWIN' not supported., for the reason please refer to Android-Determine.cmake. If you really want to use this software on Windows, please use via Docker or WSL instead.

Using ndk-pkg via GitHub Actions

This is the recommended way of using this software.

In this way, you don't need to care about other things than:

which package would you like to build? lookup package names
which minimum Android SDK API level would you like to support?
which Android ABI would you like to build for?
which build profile would you like to use?

For more details please refer to https://github.com/leleliu008/ndk-pkg-package-manually-build

Using ndk-pkg via Docker

This is the recommended way of using this software if you prefer to use this software locally due to docker container is an isolated environment where the running process can not be affected by your host system's environemt variables.

step1. create the ndk-pkg docker container

mkdir -p ~/ndk-pkg-home
mkdir -p ~/.m2

docker create -it --name ndk-pkg -v ~/ndk-pkg-home:/root/.ndk-pkg -v ~/.m2:/root/.m2 ubuntu:24.04

step2. start the ndk-pkg docker container

docker start ndk-pkg

step3. install ndk-pkg

curl -LO https://raw.githubusercontent.com/leleliu008/ndk-pkg/master/ndk-pkg
chmod a+x ndk-pkg
docker cp ndk-pkg ndk-pkg:/usr/bin/

step4. install essential tools

docker exec -it ndk-pkg ndk-pkg setup

step5. update formula repositories

docker exec -it ndk-pkg ndk-pkg update

If all goes well, then next you can start to install packages whatever you want, for example, let's install curl package for target android-34-arm64-v8a:

docker exec -it ndk-pkg ndk-pkg install curl --target=android-34-arm64-v8a

Note: you can use podman instead of docker

Install ndk-pkg via cURL

curl -LO https://raw.githubusercontent.com/leleliu008/ndk-pkg/master/ndk-pkg
chmod a+x ndk-pkg
./ndk-pkg setup

Please try the following URLs if above url is not reachable:

Install ndk-pkg via git

git clone --depth 1 https://github.com/leleliu008/ndk-pkg
ndk-pkg/ndk-pkg setup

Install ndk-pkg in WSL

Note :

As of Android NDK r25, due to use of BOLT to optimize the binaries of Android NDK for Linux , Android NDK for Linux is incompatible with WSL1. For more details please refer to android/ndk#1755

/etc/wsl.conf :

[network]
hostname = ubuntu
generateHosts = false

[automount]
enabled = true
root = /mnt/
options = "metadata,umask=22,fmask=11"
mountFsTab = true

installation instructions :

# If you want to store ndk-pkg generated data to D:\ partition
export NDKPKG_HOME=/mnt/d/ndk-pkg

# If you use Ubuntu or Debian distribution
sudo apt -y update
sudo apt -y install curl

curl -LO https://raw.githubusercontent.com/leleliu008/ndk-pkg/master/ndk-pkg
chmod a+x ndk-pkg
./ndk-pkg setup

~/.ndk-pkg

Caveats: Please do NOT place your own files under ~/.ndk-pkg directory, as ndk-pkg will change (remove, modify, override) files under ~/.ndk-pkg directory without notice.

a typical hierarchical structure under ~/.ndk-pkg directory looks like below:

environment variables

HOME

This environment variable already have been set on the most operating systems, if not set or set a empty string, you may receive an error message.
PATH

This environment variable already have been set on the most operating systems, if not set or set a empty string, you may receive an error message.
SSL_CERT_FILE
```
curl -LO https://curl.se/ca/cacert.pem
export SSL_CERT_FILE="$PWD/cacert.pem"
```
In general, you don't need to set this environment variable, but, if you encounter the reporting the SSL certificate is invalid, trying to run above commands in your terminal will do the trick.
GOPROXY
```
export GOPROXY='https://goproxy.cn'
```
NDKPKG_URL_TRANSFORM
```
export NDKPKG_URL_TRANSFORM=/path/of/url-transform
```
/path/of/url-transform command would be invoked as /path/of/url-transform <URL>

/path/of/url-transform command must output a <URL>

you can generate a url-transform sample via ndk-pkg gen-url-transform-sample

If you want to change the request url, you can set this environment variable. It is very useful for chinese users.
NDKPKG_DNS_SERVERS

DNS servers to be used instead of the system default.
```
export NDKPKG_DNS_SERVERS='1.1.1.1,8.8.8.8'
```
NDKPKG_XTRACE

For debugging purposes.

enable set -x:
```
export NDKPKG_XTRACE=1
```
NDKPKG_HOME

If this environment variable is not set or set a empty string, ~/.ndk-pkg will be used as the default value.
```
export NDKPKG_HOME=/path/of/ndk-pkg-home
```
NDKPKG_DEFAULT_TARGET

Some ACTIONs of ndk-pkg are associated with an installed package which need PACKAGE-SPEC to be specified.

PACKAGE-SPEC : a formatted string that has form: <TARGET>/<PACKAGE-NAME>, represents an installed package.

PACKAGE-NAME : should match the regular expression pattern ^[A-Za-z0-9+-_.@]{1,50}$

TARGET : a formatted string that has form: android-<ANDROID-API>-<ANDROID-ABI>

ANDROID-API : indicates which minimum Android SDK API Level was built with.

ANDROID-ABI : indicates which Android ABI was built for.

To simplify the usage, you are allowed to omit <TARGET>/. If <TARGET>/ is omitted, environment variable NDKPKG_DEFAULT_TARGET would be checked, if this environment variable is not set, then android-21-arm64-v8a will be used as the default.

Example:
```
export NDKPKG_DEFAULT_TARGET='android-34-arm64-v8a'
```

Note: some commonly used environment variables are override by this software, these are CC, CXX, CPP, AS, AR, LD, CFLAGS, CPPFLAGS, LDFLAGS, PKG_CONFIG_LIBDIR, PKG_CONFIG_PATH, ACLOCAL_PATH

ndk-pkg formula scheme

a ndk-pkg formula is a YAML format file which is used to config a ndk-pkg package's meta-information including one sentence description, package version, installation instructions, etc.

a ndk-pkg formula's filename suffix must be .yml

a ndk-pkg formula'a filename prefix would be treated as the package name.

a ndk-pkg formula'a filename prefix must match regular expression pattern ^[A-Za-z0-9+-._@]{1,50}$

a ndk-pkg formula's file content only has one level mapping and shall has following KEY:

KEY	required?	overview
`pkgtype`	optional	indicates what type of this package. value shall be any one of `exe`, `pie`, `lib`, `exe+lib`. To `exe` type package, `ndk-pkg` would add `--static -static` options to `LDFLAGS` if `--static` install option is given. To `pie` type package, it means that it doesn't support fully statically linking, it is supposed to be dynamically linked. If this mapping is not present, `ndk-pkg` will determine the package type by package name, if a package name starts/ends with `lib`, it would be recognized as type `lib`, otherwise, it would be recognized as type `exe`
`summary`	required	describe this package in one sentence.
`license`	optional	a space-separated list of SPDX license short identifiers
`version`	optional	the version of this package. If this mapping is not present, it will be extracted from `src-url` if present, otherwise it will be calculated by running command `date +%Y.%m.%d`

`web-url`	optional	the home webpage of this package. If this mapping is not present, use `git-url` if present, otherwise extract from `src-url`.

`git-url`	optional	the source code git repository. If `src-url` is not present, this mapping must be present.
`git-ref`	optional	reference: https://git-scm.com/book/en/v2/Git-Internals-Git-References example values: `HEAD` `refs/heads/master` `refs/heads/main` `refs/tags/v1`, default value is `HEAD`
`git-sha`	optional	the full git commit id, 40-byte hexadecimal string, if `git-ref` and `git-sha` both are present, `git-sha` takes precedence over `git-ref`
`git-nth`	optional	tell `ndk-pkg` that how many depth commits would you like to be fetched. default is `1`, this would save your time and storage. If you want to fetch all commits, set this to `0`

`src-url`	optional	the source code download url of this package. If value of this mapping ends with one of `.zip` `.tar.xz` `.tar.gz` `.tar.lz` `.tar.bz2` `.tgz` `.txz` `.tlz` `.tbz2` `.crate`, it will be uncompressed to `$PACKAGE_WORKING_DIR/src` when this package is installing, otherwise, it will be copied to `$PACKAGE_WORKING_DIR/src` also support format like `dir://DIR`
`src-uri`	optional	the mirror of `src-url`.

ndk-pkg formula repository

a typical hierarchical structure of a ndk-pkg formula repository looks like below:

NDKPKGFormulaRepoName
├── formula
│   ├── packageA.yml
│   └── packageB.yml
├── LICENSE
└── README.md

ndk-pkg formula repository local location

${NDKPKG_HOME}/repos.d/${NDKPKGFormulaRepoName}

ndk-pkg formula repository local config

a ndk-pkg formula repository's config file is located at ${NDKPKG_HOME}/repos.d/${NDKPKGFormulaRepoName}/.ndk-pkg-formula-repo.yml

a typical ndk-pkg formula repository's config file content looks like below:

url: https://github.com/leleliu008/ndk-pkg-formula-repository-official-core
branch: master
pinned: 0
enabled: 1
created: 1673684639
updated: 1673684767

If a ndk-pkg formula repository is pinned, which means it would not be updated.

If a ndk-pkg formula repository is disabled, which means ndk-pkg would not search formulas in this formula repository.

ndk-pkg formula repository management

run ndk-pkg formula-repo-add command to create a new formula repository locally.

ndk-pkg official formula repository

ndk-pkg official formula repository is hosted at https://github.com/leleliu008/ndk-pkg-formula-repository-official-core

It would be automatically fetched to your local repository as name official-core when you run ndk-pkg update command.

Note: If you find that a package is not in ndk-pkg official formula repository yet, PR is welcomed.

Using my prefab aars that have been published to GitHub-Hosted Maven Repository alongside with Android Gradle Plugin

I have published some commonly used packages as google prefab aar to https://github.com/leleliu008/ndk-pkg-prefab-aar-maven-repo

Using my prefab aars that have been published to Maven Central Repository alongside with Android Gradle Plugin

I have published some commonly used packages as google prefab aar to Maven Central Repository.

To get the full list of my published packages, please visit the following websites:

In the next two sections, I will show you how to configure with Android Gradle Plugin in Kotlin DSL and Groovy DSL respectively.

configure with Android Gradle Plugin Kotlin DSL

step1. enable prefab feature for Android Gradle Plugin

android {
    buildFeatures {
        prefab = true
    }
}

step2. enable Maven Central Repository for Gradle

allprojects {
    repositories {
        maven {
            mavenCentral()
        }
    }
}

中国大陆的用户可使用如下配置：

allprojects {
    repositories {
        maven {
            maven { url = uri("https://maven.aliyun.com/repository/public") }
        }
    }
}

step3. add dependencies in build.gradle.kts

Every package's coordinate for Gradle is com.fpliu.ndk.pkg.prefab.android.21:<PACKAGE-NAME>:<PACKAGE-VERSION>, for example, libpng package has a version 1.6.37, we could use it as follows:

dependencies {
    implementation ("com.fpliu.ndk.pkg.prefab.android.21:libpng:1.6.37")
}

step4. invoke find_package(PACKAGE-NAME [REQUIRED] CONFIG) command in your Android project's CMakeLists.txt

Every package provides several cmake imported targets:

TARGET-NAME	example	summary
`<PACKAGE-NAME>::headers`	`libpng::headers`	C/C++ header files only
`<PACKAGE-NAME>::lib*.a`	`libpng::libpng16.a`	static library
`<PACKAGE-NAME>::lib*.so`	`libpng::libpng16.so`	shared library
`<PACKAGE-NAME>::*`	`libpng::libpng`	base on .pc files

Following is a piece of codes show you how to link libpng.a which is provided by libpng package:

find_package(libpng REQUIRED CONFIG)
target_link_libraries(app libpng::libpng.a)

or

find_package(libpng CONFIG)
if (libpng_FOUND)
    target_link_libraries(app libpng::libpng.a)
endif()

step5. configure C++ standard and STL in build.gradle.kts

android {
    defaultConfig {
        externalNativeBuild {
            cmake {
                arguments += "-DANDROID_STL=c++_shared"
                cppFlags  += "-std=c++17"
            }
        }
    }
}

Note:

This step is only required for packages that use libc++.
If you link a shared library that depends on libc++_shared.so, then your Android app should use libc++_shared.so too.

configure with Android Gradle Plugin Groovy DSL

step1. enable prefab feature for Android Gradle Plugin

android {
    buildFeatures {
        prefab true
    }
}

step2. enable Maven Central Repository for Gradle

allprojects {
    repositories {
        maven {
            mavenCentral()
        }
    }
}

中国大陆的用户可使用如下配置：

allprojects {
    repositories {
        maven {
            url 'https://maven.aliyun.com/repository/public'
        }
    }
}

step3. add dependencies in build.gradle

Every package's coordinate for Gradle is com.fpliu.ndk.pkg.prefab.android.21:<PACKAGE-NAME>:<PACKAGE-VERSION>, for example, libpng package has a version 1.6.37, we could use it as follows:

dependencies {
    implementation 'com.fpliu.ndk.pkg.prefab.android.21:libpng:1.6.37'
}

step4. invoke find_package(PACKAGE-NAME [REQUIRED] CONFIG) command in your Android project's CMakeLists.txt

Every package provides several cmake imported targets:

TARGET-NAME	example	summary
`<PACKAGE-NAME>::headers`	`libpng::headers`	C/C++ header files only
`<PACKAGE-NAME>::lib*.a`	`libpng::libpng16.a`	static library
`<PACKAGE-NAME>::lib*.so`	`libpng::libpng16.so`	shared library
`<PACKAGE-NAME>::*`	`libpng::libpng`	base on .pc files

Following is a piece of codes show you how to link libpng.a which is provided by libpng package:

find_package(libpng REQUIRED CONFIG)
target_link_libraries(app libpng::libpng.a)

or

find_package(libpng CONFIG)
if (libpng_FOUND)
    target_link_libraries(app libpng::libpng.a)
endif()

step5. configure C++ standard and STL in build.gradle

android {
    defaultConfig {
        externalNativeBuild {
            cmake {
                arguments '-DANDROID_STL=c++_shared'
                cppFlags  '-std=c++17'
            }
        }
    }
}

Note:

This step is only required for packages that use libc++.
If you link a shared library that depends on libc++_shared.so, then your Android app should use libc++_shared.so too.
