如何查找opencv4tegra 的安装路径

Posted 2023-05-17

我刚刚在visual2010配置完opencv2.2，是按照下面的方法的，可行！与你分享一下。呵呵。希望你能成功配置。。。这里只谈预编译安装包的方法，注意，安装环境只适用于VS2010(32-bit),OpenCV2.2。其他环境请使用CMake方法。步骤：1.自行下载并安装OpenCV-2.2.0-win32-vs2010.exe（注意安装时选择把OpenCV路径添加到系统全局变量中）；2.在VS2010创建你自己的工程；3.打开projectproperties，在弹出窗口中定位到VC++Directories；4.加入“[OpenCV安装路径]\include”、“[OpenCV安装路径]\include\opencv”这两个路径到IncludeDirectory里面（目的是为了兼容2.1及其以前版本的引用头文件格式）；5.加入“[OpenCV安装路径]\lib”路径到LibraryDirectory里面；6.不要关闭当前窗口，定位到左边菜单中的Linker，再选择Input，把下面这些依赖项加进去：opencv_core220d.libopencv_highgui220d.libopencv_video220d.libopencv_ml220d.libopencv_legacy220d.libopencv_imgproc220d.lib当然，还有其他的库，视需要而添加；7.编写好程序或运行些实例看看是否能通过。 参考技术A 安装程序开始之后选择TK1，

其中Common为Jetson tk1和tx1共用文件，For Jetson TK1是其特有文件。下面为大家介绍一些安装文件的作用。
2.1 CUDA Toolkit for L4T
在移动平台上运行的CUDA，后期编译OpenCV需要，必须安装。
2.2 OpenCV4Tegra for Jetson TK1 Developer Kit
OpenCV优化包，必须安装。
2.3 NVIDIA VisionWorks Toolkit，NVIDIA VisionWorks Plus (SFM)，NVIDIA(R) VisionWorks(TM) Object Tracker
NVIDIA自家的视觉库，基于OpenVX，包含了三维重建（SFM）和跟踪模块（Object Tracker）硬件加速能力甩OpenCV一条街，建议安装。
2.4 The NVIDIA CUDA Deep Neural Network library (cuDNN)
NVIDIA自家的深度神经网络库，GPU加速能力超强，建议研究神经网络和机器学习的用户安装（其实TX1还有一个定位就是深度学习机，NVIDIA这点良心啊~）
2.5 CUDA Toolkit on Host for Cross Compiling
安装在宿主机上的CUDA，用于交叉编译。希望使用交叉编译的用户可以选择安装。
2.6 OS and File System

注意，如果你选择了这几项，就意味着你将重装Jetson TK1上的系统并且抹去所有文件，所有这一项慎选！本回答被提问者采纳

Linux如何查看JDK的安装路径

如何在一台Linux服务器上查找JDK的安装路径呢？ 有那些方法可以查找定位JDK的安装路径？是否有一些局限性呢？ 下面总结了一下如何查找JDK安装路径的方法.

 

1：echo $JAVA_HOME

使用$JAVA_HOME的话能定位JDK的安装路径的前提是配置了环境变量$JAVA_HOME，否则如下所示，根本定位不到JDK的安装路径

[root@localhost ~]# java -version

java version "1.7.0_65"

OpenJDK Runtime Environment (rhel-2.5.1.2.el6_5-x86_64 u65-b17)

OpenJDK 64-Bit Server VM (build 24.65-b04, mixed mode)

[root@localhost ~]# echo $JAVA_HOME

 

2：which java

首先要申明一下which java是定位不到安装路径的。which java定位到的是java程序的执行路径。网上的资料都是人云亦云，完全不去思考。那么怎么定位到java的安装路径呢？下面我们来看看例子吧,如下所示：

[root@localhost ~]# java -version

java version "1.7.0_65"

OpenJDK Runtime Environment (rhel-2.5.1.2.el6_5-x86_64 u65-b17)

OpenJDK 64-Bit Server VM (build 24.65-b04, mixed mode)

[root@localhost ~]# which java

/usr/bin/java

[root@localhost ~]# ls -lrt /usr/bin/java

lrwxrwxrwx. 1 root root 22 Aug 17 15:12 /usr/bin/java -> /etc/alternatives/java

[root@localhost ~]# ls -lrt /etc/alternatives/java

lrwxrwxrwx. 1 root root 46 Aug 17 15:12 /etc/alternatives/java -> /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java

[root@localhost ~]# 

[root@localhost ~]# cd /usr/lib/jvm

[root@localhost jvm]# ls

java-1.6.0-openjdk-1.6.0.0.x86_64 java-1.7.0-openjdk-1.7.0.65.x86_64 jre jre-1.6.0 jre-1.6.0-openjdk.x86_64 jre-1.7.0 jre-1.7.0-openjdk.x86_64 jre-openjdk

[root@localhost jvm]# 

whereis java 也是如此，它本身不能定位到安装路径。可以通过上面例子去定位安装路径

 

3： rpm -ql packagename

如果JDK是源码安装的话，那么这个方法也是行不通的。也就是说rpm –ql packagename也是有一定局限性的。

[root@localhost ~]# java -version

java version "1.7.0_65"

OpenJDK Runtime Environment (rhel-2.5.1.2.el6_5-x86_64 u65-b17)

OpenJDK 64-Bit Server VM (build 24.65-b04, mixed mode)

[root@localhost ~]# rpm -qa | grep java

tzdata-java-2014g-1.el6.noarch

java-1.6.0-openjdk-1.6.0.0-11.1.13.4.el6.x86_64

java-1.7.0-openjdk-1.7.0.65-2.5.1.2.el6_5.x86_64

[root@localhost ~]# rpm -ql java-1.7.0-openjdk-1.7.0.65-2.5.1.2.el6_5.x86_64 | more
