提前下好deepstream6#

下载地址：https://developer.nvidia.com/deepstream-getting-started

Copy
sudo tar -zxvf deepstream_sdk_v6.0.0_x86_64.tbz2 -C /

命令行安装gcc#

Copy
sudo apt-get install build-essential

源码编译安装gcc#

下载地址：http://mirrors.nju.edu.cn/gnu/gcc/gcc-7.5.0/

安装依赖：#

下载其他依赖文件，从这个地址都能找到:http://www.mirrorservice.org/sites/sourceware.org/pub/gcc/infrastructure/

• gmp-6.1.0.tar.bz2
• mpfr-3.1.4.tar.bz2
• mpc-1.0.3.tar.gz
• isl-0.16.1.tar.bz2
  每个依赖都使用相同的安装步骤，如下：

make -j2
sudo make install

编译安装gcc#

Copy
编译安装gcc
./configure --enable-checking=release --enable-languages=c,c++ --disable-multilib

如果出现gcc和g++版本不一致的问题,很可能是配置的问题,因为目前系统里有多个gcc了,调用如下命令,即可解决
/usr/local/bin/gcc是我的安装路径

sudo update-alternatives --install /usr/bin/gcc gcc /usr/local/bin/gcc  100
sudo update-alternatives --install /usr/bin/gcc gcc /usr/local/bin/g++  100

源码编译CPU版OpenCV#

Copy
cd opencv-4.5.1
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local/opencv-4.5.1 ..
make -j128
sudo make install

源码编译GPU版OpenCV#

** 使用源码安装opencv，注意要带cuda和gstreamer，这一步容易出现问题，将一些关键步骤做些说明，按照下边指令安装 **

安装依赖#

Copy
sudo apt-get install libavcodec-dev libavformat-dev libavdevice-dev ffmpeg
libglew-dev								OpenGL Extension Wrangler - 开发环境
libtiff5-dev							标记图像文件格式库 (TIFF)，开发文件
zlib1g-dev

libgtk2.0-dev
pkg-config

编译OpenCV#

Copy
wget https://github.com/opencv/opencv/archive/3.4.0.zip -O opencv-3.4.0.zip
unzip opencv-3.4.0.zip
cd opencv-3.4.0
wget https://github.com/opencv/opencv_contrib/archive/3.4.0.zip -O opencv_contrib-3.4.0.zip
unzip opencv_contrib-3.4.0.zip
mkdir build && cd build

make -j128
sudo make install

查看显卡CUDA_ARCH_BIN

• 方法1：利用cuda_sample查看

Copy

cd /usr/local/cuda/samples/1_Utilities/deviceQuery
sudo make
./deviceQuery

输出其中的** CUDA Capability Major/Minor version number: 7.5 **

• 方法2：git下载代码编译

Copy
git clone https://github.com/NVIDIA-AI-IOT/deepstream_tlt_apps.git
cd deepstream_tlt_apps/TRT-OSS/x86
nvcc deviceQuery.cpp -o deviceQuery
./deviceQuery

检测版本#

Copy
pkg-config --modversion opencv
pkg-config --cflags --libs opencv
# or
python
import cv2
cv2.getBuildInformation()

安装编译好的opencv python库#

Copy
cd opencv-3.4.0/build/python_loader/
python setup.py install

可能的报错#

Copy
1.找不到gst/gstxxx.hpp问题
在/usr/include下新建软连接
$ cd /usr/include
$ sudo ln -s gstreamer-1.0/gst/ gst

2.dynlink_nvcuvid.h问题
cuda10不再提供dynlink_nvcuvid.h功能，修改opencv-3.4.0/modules/cudacodec/src目录下的文件

modules/cudacodec/src/precomp.hpp
modules/cudacodec/src/video_decoder.hpp
modules/cudacodec/src/video_parser.hpp
modules/cudacodec/src/cuvid_video_source.hpp
modules/cudacodec/src/frame_queue.hpp
找到下边的代码

#if CUDA_VERSION >= 9000
#include <dynlink_nvcuvid.h>
#else
#include <nvcuvid.h>
#endif
替换为

#if CUDA_VERSION >= 9000 && CUDA_VERSION < 10000
#include <dynlink_nvcuvid.h>
#else
#include <nvcuvid.h>
#endif
如果改完还报错的话，需要下载 nvidia-sdk，下载链接：https://developer.nvidia.com/designworks/video_codec_sdk/downloads/v9.0

下载解压后将其中的 nvcuvid.h, cuviddec.h copy 到 /usr/local/cuda/include

然后重新make即可 

3.ippicv_2017u3_lnx_intel64_general_20170822.tgz下载慢问题
https://github.com/opencv/opencv_3rdparty/tree/ippicv/master_20170822/ippicv
查看build目录下的CmakeDownloadLog.txt，里边记录了下载地址，我这里的路径是

use_cache "/home/nvidia/opencv_3.4.0/opencv-3.4.0/.cache"
do_unpack "ippicv_2017u3_lnx_intel64_general_20170822.tgz" "4e0352ce96473837b1d671ce87f17359" "https://raw.githubusercontent.com/opencv/opencv_3rdparty/dfe3162c237af211e98b8960018b564bc209261d/ippicv/ippicv_2017u3_lnx_intel64_general_20170822.tgz" "/home/nvidia/opencv_3.4.0/opencv-3.4.0/build/3rdparty/ippicv"
#check_md5 "/home/nvidia/opencv_3.4.0/opencv-3.4.0/.cache/ippicv/4e0352ce96473837b1d671ce87f17359-ippicv_2017u3_lnx_intel64_general_20170822.tgz"

可以看到是把这个文件下载到/home/nvidia/opencv_3.3.1/opencv-3.3.1/.cache/ippicv/下，并命名为4e0352ce96473837b1d671ce87f17359-ippicv_2017u3_lnx_intel64_general_20170822.tgz，我们只需要把手动下载的文件然后复制到该路径下即可

4 cblas_xxx问题
如果出现编译问题“undefined reference to `cblas_sgemm(CBLAS_ORDER, CBLAS_TRANSPOSE, CBLAS_TRANSPOSE, int, int, int, float, float const, int, float const, int, float, float*, int)'”

可能需要重新编译BLAS，CBLAS，LPACK，参考链接《blas、lapack、cblas在Ubuntu上的安装》<https://www.jianshu.com/p/33c4aea6117b>

5 boostdesc_bgm.i等问题
在opencv_contrib目录中报错fatal error: boostdesc_bgm.i: No such file or directory

这个跟2.4.2类似，是有些包下载不成功导致的，可以直接下载https://github.com/nanmi/myresource/tree/main/opencv_3rdparts/下面的资源，参考链接：<https://github.com/opencv/opencv_contrib/issues/1301>，然后拷贝到opencv_contrib/modules/xfeatures2d/src/ 路径下，重新编译即可

6 多版本问题
如果之前安装过其它版本没有卸载，可以采用《Ubuntu下多个版本OpenCV管理（Multiple Opencv version）》来指定编译时用到的opencv版本，连接：<https://www.cnblogs.com/cmt/p/14580194.html?from=https%3A%2F%2Fwww.cnblogs.com%2Fxzd1575%2Fp%2F5555523.html>

7 opencv2/xfeatures2d/cuda.hpp问题
修改/opencv-3.4.0/modules/stitching/CMakeLists.txt文件，在开头增加下边内容，然后重新cmake和make

INCLUDE_DIRECTORIES("/<your location>/opencv_contrib-3.4.0/modules/xfeatures2d/include") 

如果修改后还报错，则找到报错的文件，将头文件改成绝对路径 

8 "xxxx/test_detectors_invariance.impl.hpp"问题
一般是说在features2d/test目录下没有XXX.hpp什么的，处理方式是将opencv-3.3.1/modules/features2d/test该目录下对于的缺少文件复制到opencv_contrib-3.3.1/modules/xfeatures2d/test该目录下，然后修改报错的文件的#include，将前面的地址删除，就让其在本地找

例如 :报错说在文件test_rotation_and_scale_invariance.cpp中找不到#include "xxxx/test_detectors_invariance.impl.hpp"，那么就在opencv-3.3.1/modules/features2d/test下去找test_detectors_invariance.impl.hpp文件，将其复制到opencv_contrib-3.3.1/modules/xfeatures2d/test目录，然后打开test_rotation_and_scale_invariance.cpp文件，修改#include "xxxx/test_detectors_invariance.impl.hpp"为#include "test_detectors_invariance.impl.hpp"即可

如果觉得难得每个文件去找，那么干脆将目录中的所有文件复制过去，之后就该对于报错文件的#include位置就好了。

安装DeepStream#

Copy
cd /opt/nvidia/deepstream/deepstream-6.0/
sudo ./install.sh
sudo ldconfig

# 查看安装的版本
deepstream-app --version-all

可能的报错#

Copy
1. 如果运行时报错提示找不到一些库，如libnvdsgst_meta.so，则需要把deepstream-6.0/lib添加到系统lib路径中，如下
sudo vim /etc/ld.so.conf
/opt/nvidia/deepstream/deepstream-6.0/lib/       //在文本后边添加该路径
sudo ldconfig    //执行ldconfig立即生效

2. 使用这个shell命令来测试 deepstream-app -c source30_1080p_dec_infer-resnet_tiled_display_int8.txt
如果报错：
** ERROR: <create_multi_source_bin:714>: Failed to create element 'src_bin_muxer'
** ERROR: <create_multi_source_bin:777>: create_multi_source_bin failed
** ERROR: <create_pipeline:1045>: create_pipeline failed
** ERROR: <main:632>: Failed to create pipeline
Quitting
App run failed

则是因为gstreamer缓存问题，运行下边指令删除即可，运行成功后，会显示检测画面。

rm ${HOME}/.cache/gstreamer-1.0/registry.*

如果是在服务器上运行，没有显示界面的话会报错如下
No EGL Display 
nvbufsurftransform: Could not get EGL display connection
需要修改环境变量，如下
vim ~/.bashrc
#打开后在最后边加下边语句
unset DISPLAY
export DISPLAY=:0 
#或者 export DISPLAY=:1

#保存退出
source ~/.bashrc
rm ${HOME}/.cache/gstreamer-1.0/registry.*

#然后再运行
deepstream-app -c source30_1080p_dec_infer-resnet_tiled_display_int8.txt
