Compile Bash for Android

本文详细介绍了如何将Bash 4.1编译为ARM架构的过程,包括获取Bash源码、下载适用于ARM的编译工具链(如Sourcery G++ Lite 2008q1-126)、配置编译参数以及最终完成静态链接的Bash编译。

1. Get the bash source:

$ wget -c http://ftp.gnu.org/gnu/bash/bash-4.1.tar.gz

$ tar zxvf bash-4.1.tar.gz

 

2. Download the ARM Toolkit , e.g. Sourcery G++ Lite 2008q1-126 for ARM GNU /Linux

$ wget -c http://www.codesourcery.com/sgpp/lite/arm/portal/package2549/public/arm-none-linux-gnueabi/arm-2008q1-126-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2

note:  using the newest toolchain compile bash-4.1 failed, use this toolchain 4.2.3 compiled ok.

 

 

3. configure the bash

$ cd bash-4.1

$./configure -host=arm-linux --enable-static-link --without-bash-malloc CC=/yourpath/arm-2008q1/bin/arm-none-linux-gnueabi-gcc

 

 

4. compile the bash

$ make

$ arm-none-linux-gnueabi-strip bash

$ file bash

bash: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, for GNU/Linux 2.6.14, stripped

### Chromium on Android Development and Usage #### Extracting Headers for Specific Modules in Chromium for Android Integration To integrate specific modules of the Chromium project into an Android application, one can utilize a script that extracts necessary header files from the Chromium source code repository. The command line tool `chromium_mod_headers_extracter.py` facilitates this process by accepting parameters such as the path to the root directory (`src`) of the Chromium codebase, output directories, module names like 'net', 'base' or 'url', along with optional target paths where these headers should be saved; if not specified, it defaults to saving them within the current working directory[^1]. For instance: ```bash $ chromium_mod_headers_extracter.py ~/data/chromium_android/src out/Default net ``` This operation specifically targets extracting headers related to network functionalities provided by Chromium. #### Understanding Multi-Process Architecture Impact on Web Page Display The design philosophy behind Chromium emphasizes security through isolation via its multi-process architecture which also plays a significant role when displaying web content efficiently while maintaining performance standards expected across different platforms including mobile environments like those powered by Android operating systems[^2]. This means developers must consider how processes communicate securely between each other during app development phases especially concerning rendering engines used inside browsers built upon Chromium framework. #### Setting Up Build Configuration Using GN Toolchain When preparing to compile custom builds tailored towards Android devices running versions based off upstream Chromium releases, setting up appropriate build configurations becomes crucial using tools like GN (Generate Ninja). Developers are encouraged to explore documentation available at official resources detailing steps required for configuring environment variables alongside specifying desired options ensuring compatibility with intended hardware specifications targeted by final products derived therefrom[^3]. --related questions-- 1. What modifications need to occur in order to optimize Chromium's multi-process architecture for better battery life on Android? 2. How does integrating selected components directly impact APK size and what strategies exist to minimize bloatware without sacrificing functionality? 3. Can you provide examples demonstrating effective use cases involving cross-platform capabilities offered by embedding Chromium-based WebView solutions into native applications? 4. In terms of user experience, what new features have been introduced recently aimed particularly toward enhancing privacy controls over browsing sessions conducted via Chrome Custom Tabs interface?
