why and how to fix ,answer in chinese 

2. install step

cmake .. -DCMAKE_CUDA_ARCHITECTURES="75"
make -j20

3. reason

这个错误提示 nvcc fatal : Unsupported gpu architecture 'compute_89'，表明你的CUDA编译器不支持目标GPU架构compute_89。可能的原因是你的CUDA版本较旧，不支持最新的GPU架构。

要解决这个问题，你可以尝试以下方法：

方法1：修改目标GPU架构

修改CMakeLists.txt文件，将不支持的GPU架构移除或替换为你的CUDA版本支持的架构。

1. 打开涉及CUDA编译选项的CMakeLists.txt文件。

2. 查找设置CUDA_ARCHITECTURES或类似选项的部分，通常看起来像这样：

   set(CUDA_ARCHITECTURES "compute_89")

3. 修改为你的CUDA版本支持的架构，例如compute_75（适用于NVIDIA Turing架构的GPU）：

   set(CUDA_ARCHITECTURES "compute_75")

方法2：更新CUDA工具包

确保你使用的是最新版本的CUDA工具包。新的版本可能支持最新的GPU架构。

1. 移除现有的CUDA工具包：

   sudo apt-get remove --purge cuda
   sudo apt-get autoremove

2. 下载并安装最新版本的CUDA工具包 ：

   从NVIDIA的CUDA下载页面下载并安装适合你的系统的最新版本。

3. 重启并验证CUDA版本：

   nvcc --version

方法3：在CMake中手动设置CUDA编译选项

在调用CMake时手动设置CUDA编译选项以匹配你的GPU架构。

1. 进入你的构建目录：

   cd /home/sun/3d/glomap/build

2. 运行CMake命令并指定支持的CUDA架构：

   cmake .. -DCMAKE_CUDA_ARCHITECTURES="75"

通过这些步骤，你应该能够解决compute_89架构不支持的问题并成功编译项目。如果问题仍然存在，请提供进一步的错误信息，以便更好地帮助你解决问题。
