从Linux发行版生成sysroot树的实用程序
cross-sysroot的Python项目详细描述
cross-sysroot
cross-sysroot是生成用于交叉编译的sysroot的实用程序。
该工具需要目标Linux发行版的名称、版本、目标体系结构以及包含所需主要软件包列表的文件。
该工具将解决包依赖关系并将其提取到给定的sysroot路径中。
生成的sysroot可以用作toolchain命令行参数--sysroot=
安装实用程序：
pip3 install cross-sysroot命令用法：
usage: cross-sysroot [-h] [--verbose] --distribution {debian,ubuntu,raspbian}
--distribution-version DISTRIBUTION_VERSION
[--distribution-url DISTRIBUTION_URL] --architecture
{amd64,arm64,armhf,armel} --build-root BUILD_ROOT
package_list_file
Build package list for Linux Distribution.
positional arguments:
package_list_file File containing the list of packages (and their
versions)
optional arguments:
-h, --help show this help message and exit
--verbose Verbose mode
--distribution {debian,ubuntu, raspbian}
Linux distribution
--distribution-version DISTRIBUTION_VERSION
Linux distribution
--distribution-url DISTRIBUTION_URL
Linux distribution URL
--architecture {amd64,arm64,armhf,armel}
CPU Architecture
--build-root BUILD_ROOT
Location to store the Linux Distribution package.
--cross-gcc CROSS_GCC
GCC Path used to build the cross application. When
set, all GCC sysroot files are copied into the
sysroot.
- 例1：
cross-sysroot --distribution debian --distribution-version stable --architecture arm64 --build-root /tmp/cross-sysroot tests/requirements-debian-jessie-arm64.txt
- 示例2：考虑
CROSS_COMPILE环境变量指向交叉编译工具链：
cross-sysroot --distribution debian --distribution-version stable --architecture arm64 --build-root /tmp/cross-sysroot --cross-gcc ${CROSS_COMPILE}gcc tests/requirements-debian-jessie-arm64.txt
关于开发/ci的说明
从源代码树启动python应用程序：
PYTHONPATH=$PWD python3 -m cross_sysroot.cross_sysroot --help生成新的PIP包
在代码上运行python linter:
sudo apt get安装pylint3 Pylint3跨系统根
在源树中运行测试：
PYTHONPATH=$PWD pytest
