1.1.1. 修改配置文件¶

修改ebf_yocto_bsp/sources/base/setup-environment

DL_DIR ?= “${BSPDIR}/downloads/” 修改默认下载位置 DL_DIR ?= “${BSPDIR}/../downloads/”

1.1.2. 出错¶

ERROR: OE-core’s config sanity checker detected a potential misconfiguration.

Either fix the cause of this error or at your own risk disable the checker (see sanity.conf). Following is the list of potential problems / advisories:

DISTRO ‘fsl-imx-X11’ not found. Please set a valid DISTRO in your local.conf

Summary: There was 1 ERROR message shown, returning a non-zero exit code.

debian mp157 qt开发环境

拷贝源码到debian 解压安装环境

https://wiki.qt.io/Building_Qt_5_from_Git

apt-get build-dep sudo apt-get install build-essential perl python git sudo apt-get install ‘^libxcb.*-dev’ libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev libxkbcommon-x11-dev

sudo aptitude install gcc g++ build-essential make automake autogen autoconf sudo apt-get install gcc g++ build-essential make automake autogen autoconf

aptitude 与 apt-get 一样，是 Debian 及其衍生系统中功能极其强大的包管理工具。与 apt-get 不同的是，aptitude 在处理依赖问题上更佳一些。
