Here are customized distribution of Android NDK 1.6_r1 which I have rebuilt from official
sources. Support of C++ exceptions, RTTI and Standard C++ Library added.
Actually only some build scripts and configuration include files were changed.
CrystaX NDK包含若干开源许可证. 详见每个模块的版权声明文件.
请注意CrystaX NDK发布包中也包括编译器,链接器,文档等的预编译二进制文件.
工具链的源码在GitHub
(你可以使用编译脚本自动下载它).
预编译的GCC和其他二进制文件(GDB, binutils 等等)基于the GNU General Public License (GPL) 或 the GNU Lesser General Public License (LGPL).
详见COPYING和COPYING.LIB,位于 $NDK/toolchains/$tc/prebuilt/$system.
预编译的LLVM/Clang工具链基于
LLVM "BSD" license.
基本上, 授权规则等同于Google's Android NDK - 例如, 允许商业&非商业用途. 唯一区别是CrystaX部分, 基于
BSD 2-clause license.
CrystaX NDK contains code from libc library of FreeBSD project which by-turn contains
code from other projects. Also, several another open-source projects used, such as GNU gcc,
GNU binutils, LLVM clang, LLVM libc++ etc. To see specific authors and/or licenses, look
into appropriate source file. Here is license for those parts which are not derived from
any other projects but written by CrystaX.

You can also build your own distribution if you don't want to use my prebuilt versions. To do it, follow instructions below.
Required development tools:
- For Windows, a recent release of Cygwin is required
- GNU Make 3.81 or later
- GNU Makeinfo (most recent version)
- GIT (for downloading toolchain sources)
- Most recent GNU Libtool packages (automake, autoconf etc)
- GNU C/C++ 3.x or later (for Windows, it should be exactly 3.x, not 4.x)
- ncurses library (for Cygwin, it should be ncurses-devel package)
- GNU flex (most recent version)
- patch utility. Most likely, it is already installed if you are using Linux or Mac OS X; however, in Cygwin it should be installed explicitly
Instructions
- Download my patch and store it somewhere
- Download android-ndk-1.6_r1 for your platform from android web site
- Unpack downloaded file and go to directory android-ndk-1.6_r1
- Apply my patch:
patch -p1 <path-to-my-patch
- Point environment variable ANDROID_NDK_ROOT to the current directory:
export ANDROID_NDK_ROOT=`pwd`
- For Windows, point environment variable CC to the GCC 3:
export CC=gcc-3
- Run build script:
./build/tools/build-toolchain.sh
It will download android toolchain sources (including binutils, gcc and gdb), patch and compile them.
It could take lot of time depending on your configuration so be patient.
- Now you are ready to test it. Try to compile application hello-jni (I've modified it, so there are STL and exceptions in the code)
using instructions from Android team
- Enjoy!
Thank you for downloading CrystaX NDK
(will start in seconds)!
CrystaX NDK is a fully open source project, free to use in any open-source and commercial environment.
We provide it free for use and don't ask our users to pay in exchange. However, we appreciate your support,
through sending us pull requests,
spreading the news about CrystaX NDK over the world, or just donating:
Who we are
We're a small team of developers who want to make development for Android easier.
Our goal is to create a comprehensive toolkit for native development for Android on C, C++, Objective-C,
and, potentially, in other programming languages already working on modern POSIX systems
(Swift, D, Haskell, Ocaml, Python, Ruby - you name it).
We've already done a lot (as you can see on our main project page),
but we want to do even more. We have a long way to go, but we know how to do it and can clearly see
the steps required to make it happen. You can read more about us here.
Why we need your support
Since we started working on CrystaX NDK, we have funded ourselves without any sponsorship.
That has led us to make money in other ways (such as working as contractors and doing consulting
jobs on other projects) and invest our earnings in the CrystaX NDK project.
Because of this we have only been able to work on NDK part-time, which means it is not
as powerful as it could be.
Having support from the community, we could pay more attention to CrystaX NDK development, without the
distraction on paid contracts. This will speed up CrystaX NDK development as well as
bug fixing and support.
Optionally, sponsors (those who send us $200/month or more) get in exchange a number of perks -
they get priority for consulting or training needs, they can be listed on the front page of the
CrystaX website and mentioned in the project README, etc.
Please read here for more details about
sponsoring options.
WARNING!
When the download is finished, please check that the downloaded file is not corrupted!
The SHA-256 hash must be .
Here is an example of how to check it using OpenSSL:
$ CHECKSUM= && \
FILE= && \
diff <(openssl sha256 $FILE) <(echo "SHA256($FILE)= $CHECKSUM") \
&& echo 'OK' || echo '*** CORRUPTED!!!'
