g++: error: release/.o: No such file or directory

这个错误通常表示 g++ 编译器无法找到指定的文件或目录。请确保你的编译命令中正确指定了要编译的源文件，并且源文件存在于正确的位置。

另外，检查一下你的编译命令是否正确。确保你没有拼写错误，包括文件名、路径和命令选项。还要确认你是否在正确的目录下执行编译命令。

如果问题仍然存在，可以提供更多的细节，例如你的编译命令和项目结构，这样我就能够更具体地帮助你解决问题。

golang ./opencv.h:10:10: fatal error: opencv/cv.h: No such file or directory

This error occurs when the compiler is unable to find the header file "opencv/cv.h" which is required for the program to compile successfully.

To resolve this error, you need to make sure that OpenCV is installed on your system and the correct header files are included in the search path.

Here are the steps to install OpenCV on Ubuntu:

1. Open a terminal window and run the following command to update the package list:

`sudo apt-get update`

2. Install the required dependencies by running the following command:

`sudo apt-get install build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev`

3. Clone the OpenCV repository by running the following command:

`git clone https://github.com/opencv/opencv.git`

4. Navigate to the OpenCV directory and create a build directory:

`cd opencv`

`mkdir build`

`cd build`

5. Configure the OpenCV build by running the following command:

`cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..`

6. Compile OpenCV by running the following command:

`make -j4`

7. Install OpenCV by running the following command:

`sudo make install`

Once OpenCV is installed, you need to make sure that the correct header files are included in the search path. You can do this by adding the following line to your code:

`#include <opencv2/opencv.hpp>`

This should resolve the "opencv/cv.h: No such file or directory" error.

ninja: error: loading 'build.ninja': No such file or directory

这个错误通常是由于在执行 `ninja` 命令时，当前目录不是 Clang 6.0 编译目录所致。你需要先进入 Clang 6.0 编译目录，然后再执行 `ninja` 命令。

请按照以下步骤操作，以进入 Clang 6.0 编译目录：

1. 打开终端，并进入 Clang 6.0 源码目录。

   cd clang-6.0.0.src

2. 创建一个 build 目录，并进入该目录。

   mkdir build
   cd build

3. 配置编译选项。在终端中运行以下命令：

   cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_INSTALL_PREFIX=/usr/local/clang ..

4. 编译静态库。在终端中运行以下命令：

   ninja clang{,++} -j8

如果编译成功，你应该可以在当前目录看到生成的 `build.ninja` 文件。此时，你可以执行 `ninja` 命令来安装静态库和相关的软件包。

sudo ninja install-clang{,++}

如果你仍然遇到 `ninja: error: loading 'build.ninja': No such file or directory` 错误，请检查当前目录是否为 Clang 6.0 编译目录，并确保你已经成功地执行了上述步骤。
