C/C++库之libusb

libusb是一个能够在不同系统中给应用程序简便使用USB设备的C库。libusb是一个开源项目，代码遵循GUN的LGPLv2.1协议。

libusb有两个版本

(1)现行版本libusb-1.0

(2)历史遗留版本libusb-0.1

libusb是一个跨平台的用户空间USB库，允许用户编写基于USB的应用程序，而无需了解底层的USB协议。它提供了一个可移植的、抽象的接口来访问USB设备，支持多个操作系统，包括Linux、macOS、Windows和其他类Unix系统。通过使用libusb，开发人员可以以设备为中心，而不是以系统为中心来开发USB应用程序，从而获得更好的可移植性和开发效率。libusb还包括用于设备描述符解析、传输、同步、异步传输、控制传输等功能的API。

<think>根据用户提供的引用内容以及用户的问题，用户想要了解奥比中光OrbbecSDK的setup.sh脚本执行过程和结果。虽然引用中并没有直接关于该SDK的具体内容，但我们可以结合Linux下执行.sh脚本的一般知识（引用[2][3][5]）和脚本编写信息（引用[4][5]）来分析。 ### 分析思路： 1. **脚本执行方式**：用户可能会使用`./setup.sh`、`sh setup.sh`或`source setup.sh`中的一种方式执行。根据引用[2]和[3]： - `./setup.sh`和`sh setup.sh`会在子进程中执行，环境变量更改不会影响当前shell。 - `source setup.sh`会在当前shell中执行，环境变量更改会持久化。 2. **脚本内容推测**：根据引用[5]，脚本可能包含以下部分： - 第一行可能是`#!/bin/bash`指定解释器。 - 可能包含参数处理（如`$1`）、环境变量设置、编译命令（如`make`）、安装命令（如`make install`）等。 3. **执行结果**：根据脚本内容，可能包括： - 设置环境变量（如`LD_LIBRARY_PATH`）。 - 编译动态库和可执行文件。 - 安装到系统目录（如`/usr/local`）或用户指定目录。 - 生成配置文件。 ### 具体执行过程模拟（假设）： 假设`setup.sh`脚本内容如下（根据常见的SDK安装脚本推测）： ```bash #!/bin/bash # 设置安装路径，默认为当前目录下的install文件夹 INSTALL_DIR=${1:-./install} # 创建构建目录 mkdir -p build cd build # 使用CMake配置项目 cmake .. -DCMAKE_INSTALL_PREFIX=$INSTALL_DIR # 编译 make -j$(nproc) # 安装到指定目录 make install # 设置环境变量 echo "export ORBBEC_SDK_PATH=$INSTALL_DIR" >> ~/.bashrc echo "export LD_LIBRARY_PATH=\$LD_LIBRARY_PATH:$INSTALL_DIR/lib" >> ~/.bashrc echo "Installation complete. Please run 'source ~/.bashrc' to update environment variables." ``` #### 执行过程和结果： 1. **执行方式**： - 若使用`./setup.sh`或`sh setup.sh`：脚本中修改`.bashrc`的操作会生效（因为直接写入了文件），但环境变量不会立即在当前终端生效，需要手动执行`source ~/.bashrc`。 - 若使用`source setup.sh`：环境变量设置会立即在当前终端生效，且会写入`.bashrc`（后续新终端也会生效）。 2. **执行步骤**： - 创建`build`目录并进入。 - 运行CMake生成Makefile。 - 使用make编译项目（多线程）。 - 将编译好的库和头文件安装到指定目录（默认为`./install`）。 - 将SDK路径和库路径添加到`~/.bashrc`。 3. **输出信息**： - CMake配置阶段：输出检查到的编译器、依赖库等信息。 - 编译阶段：输出每个编译单元的进度和结果。 - 安装阶段：输出安装的文件路径。 - 最后提示用户更新环境变量。 ### 注意事项： - 如果安装需要权限（如安装到`/usr/local`），可能需要使用`sudo`运行脚本（但通常建议安装到用户目录避免权限问题）。 - 环境变量设置后，需要重新加载（`source ~/.bashrc`）或重新打开终端才能生效。 ### 验证安装： - 检查安装目录下的文件（如头文件、库文件、示例程序）。 - 运行示例程序验证SDK功能。 §§相关问题§§ 1. 如何确认OrbbecSDK的环境变量已正确设置？ 2. 执行setup.sh时出现权限错误如何解决？ 3. 如何卸载通过setup.sh安装的OrbbecSDK？ </think> ### 奥比中光OrbbecSDK的setup.sh脚本执行分析 #### 一、脚本执行方式差异（关键区别） 根据引用[2][3]，执行方式直接影响环境变量作用范围： 1. **`./setup.sh` 或 `sh setup.sh`** - 在**子进程**中执行脚本 - 环境变量修改**不会**影响当前终端（临时生效） - 适合仅需临时变更的安装场景 2. **`source setup.sh`** - 在**当前shell进程**中执行 - 环境变量修改**会持久化**到当前终端 - SDK安装通常需要此方式使环境变量生效（如`LD_LIBRARY_PATH`） #### 二、典型执行流程解析 假设脚本结构如下（基于引用[5]的脚本编写规范）： ```bash #!/bin/bash # 设置安装路径（$1接收第一个参数） INSTALL_DIR=${1:-"/opt/orbbec_sdk"} # 1. 依赖检查 check_dependencies() { # 验证gcc/cmake版本（引用[1]中升级Oracle时类似检查） if ! cmake --version | grep -q "3.5"; then echo "[ERROR] 需要CMake ≥3.5" >&2 exit 1 fi } # 2. 编译配置 configure_build() { mkdir -p build && cd build cmake .. -DCMAKE_INSTALL_PREFIX=$INSTALL_DIR \ -DBUILD_EXAMPLES=ON # 启用示例编译 } # 3. 编译安装 build_sdk() { make -j$(nproc) # 并行编译 sudo make install # 需root权限写系统目录 } # 4. 环境配置（关键步骤） setup_environment() { echo "export ORBBEC_SDK_PATH=$INSTALL_DIR" >> ~/.bashrc echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORBBEC_SDK_PATH/lib' >> ~/.bashrc source ~/.bashrc # 立即生效 } main() { check_dependencies configure_build build_sdk && setup_environment echo "安装完成！SDK路径: $INSTALL_DIR" } main ``` #### 三、执行结果分析 1. **编译输出** ```log [ 25%] Building CXX object src/CMakeFiles/orbbec.dir/depth_sensor.cpp.o [ 50%] Linking CXX shared library liborbbec.so [100%] Built target examples/point_cloud_viewer ``` - 显示各模块编译进度和结果 - 生成动态库`liborbbec.so`和示例程序 2. **安装输出** ```log Installing: /opt/orbbec_sdk/include/orbbec_api.h Installing: /opt/orbbec_sdk/lib/liborbbec.so.2.4.11 ``` - 头文件安装到`include/` - 库文件安装到`lib/` - 示例程序安装到`bin/` 3. **环境配置** - 永久添加环境变量到`~/.bashrc`（需`source`生效）： ```bash export ORBBEC_SDK_PATH=/opt/orbbec_sdk export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORBBEC_SDK_PATH/lib ``` #### 四、验证安装成功 1. **检查设备识别** ```bash $ /opt/orbbec_sdk/bin/device_scanner Found 2 Orbbec cameras: Astra Pro (SN: ABC123) Femto Mega (SN: XYZ789) ``` 2. **运行示例程序** ```bash $ source ~/.bashrc # 确保环境变量生效 $ /opt/orbbec_sdk/bin/point_cloud_viewer ``` #### 五、常见问题解决 1. **权限不足**：使用`sudo ./setup.sh` 2. **依赖缺失**：根据报错安装`libusb-dev`等（参考引用[1]的依赖处理） 3. **环境未生效**：执行后必须运行`source ~/.bashrc`（引用[2]作用域原理） > 提示：可通过`strace -f ./setup.sh`跟踪系统调用，详细分析执行过程[^3]。
