【Xilinx】如何脱离petalinux环境直接编译vcu-gst-app_error: nothing provides 'vcu-gst-app

Xilinx从2018.1开始，提供了一套基于zcu106的vcu参考设计，目前最新版本是2021.2。
https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841711/Zynq+UltraScale+MPSoC+VCU+TRD

里面提供了一套基于GStreamer的程序，即vcu-gst-app。但是这个需要基于petalinux环境编译：

petalinux-build -c vcu-gst-app
1

如何脱离petalinux直接编译呢，这里以PetaLinux2020.2为例，其他版本也是类似的操作

一、工具准备

1.创建工程

这步与正常的创建petalinux工程一样。详细步骤可以参考

Petalinux快速入门向导 (4) 第三章.PetaLinux开发基本流程

2.编译并安装sdk

编译对应的sdk，后续需要用到这个编译器来编译我们的代码

petalinux-build --sdk
petalinux-package --sysroot
1
2

在我的电脑上，工程目录是/opt/work/p202/xilinx-vcu-zcu106-v2020.2-final/
安装后的sdk路径是./images/linux/sdk
完整路径是/opt/work/p202/xilinx-vcu-zcu106-v2020.2-final/images/linux/sdk

二、源代码准备

1. 默认的源代码目录

默认源代码位于project-spec/meta-user/recipes-apps/vcu-gst-app目录下
目录结构为

2.整理后的代码目录

创建新目录/opt/work/p202/vcu-gst-app，再创建app，把vcu_gst_app.zip解压到目录下
创建lib子目录，把另外3个压缩包解压到目录下。
完整的目录结构为

三、配置Makefile

1.修改Makefile.am中的默认路径

1.1 修改路径recipe-sysroot

打开gedit Makefile.am ，搜索recipe-sysroot
共搜索到4处

vcu_gst_app_CFLAGS = $(VCU_GST_CFLAGS) -I$(vcu_gst_app_INC_DIR) -I$(vcu_apm_lib_INC_DIR) -I$(vcu_video_lib_INC_DIR) -I$(vcu_gst_lib_INC_DIR) -I../recipe-sysroot/usr/include/drm -I../recipe-sysroot/usr/include
libvcu_apm_lib_a_CFLAGS = $(VCU_GST_CFLAGS) -I$(vcu_apm_lib_INC_DIR)
libvideo_a_CFLAGS = $(VCU_GST_CFLAGS) -I$(vcu_video_lib_INC_DIR) -I../recipe-sysroot/usr/include/drm -I../recipe-sysroot/usr/include
1

因为这个路径与实际的路径不符，所以需要修改这几个地方
比如，在我的电脑，路径为/opt/work/p202/xilinx-vcu-zcu106-v2020.2-final/images/linux/sdk/sysroots/aarch64-xilinx-linux，所以要把
…/recipe-sysroot
替换成
/opt/work/p202/xilinx-vcu-zcu106-v2020.2-final/images/linux/sdk/sysroots/aarch64-xilinx-linux

替换后如下：

vcu_gst_app_CFLAGS = $(VCU_GST_CFLAGS) -I$(vcu_gst_app_INC_DIR) -I$(vcu_apm_lib_INC_DIR) -I$(vcu_video_lib_INC_DIR) -I$(vcu_gst_lib_INC_DIR) -I/opt/work/p202/xilinx-vcu-zcu106-v2020.2-final/images/linux/sdk/sysroots/aarch64-xilinx-linux/usr/include/drm -I/opt/work/p202/xilinx-vcu-zcu106-v2020.2-final/images/linux/sdk/sysroots/aarch64-xilinx-linux/usr/include
libvcu_apm_lib_a_CFLAGS = $(VCU_GST_CFLAGS) -I$(vcu_apm_lib_INC_DIR)
libvideo_a_CFLAGS = $(VCU_GST_CFLAGS) -I$(vcu_video_lib_INC_DIR) -I/opt/work/p202/xilinx-vcu-zcu106-v2020.2-final/images/linux/sdk/sysroots/aarch64-xilinx-linux/usr/include/drm -I/opt/work/p202/xilinx-vcu-zcu106-v2020.2-final/images/linux/sdk/sysroots/aarch64-xilinx-linux/usr/include

1.2修改路径…/vcu_gst_apps/

…/vcu_gst_apps/要求项目所在的目录名必须是vcu_gst_apps，这明显不合理，实际只需要使用当前路径**./**即可

vcu_gst_app_INC_DIR = ../vcu_gst_apps/app/vcu_gst_app/include
vcu_apm_lib_INC_DIR = ../vcu_gst_apps/lib/vcu_apm_lib/include
vcu_video_lib_INC_DIR = ../vcu_gst_apps/lib/vcu_video_lib/include
vcu_gst_lib_INC_DIR = ../vcu_gst_apps/lib/vcu_gst_lib/include
1
2

4

把…/vcu_gst_apps修改为./

vcu_gst_app_INC_DIR = ./app/vcu_gst_app/include
vcu_apm_lib_INC_DIR = ./lib/vcu_apm_lib/include
vcu_video_lib_INC_DIR = ./lib/vcu_video_lib/include
vcu_gst_lib_INC_DIR = ./lib/vcu_gst_lib/include

2.运行autogen.sh

./autogen.sh --host=arm

1.初始化sdk的环境变量

source运行environment-setup-aarch64-xilinx-linux配置

source /opt/work/p202/xilinx-vcu-zcu106-v2020.2-final/images/linux/sdk/environment-setup-aarch64-xilinx-linux

2.make

执行make即可编译生成后会生成vcu-gst-app

用readelf命令可以查看文件格式

xlx@u16:/opt/work/p202/vcu-gst-app$ readelf -h vcu_gst_app
