这个错误通常表示你的程序无法找到所需的共享库文件 `libpcl_common.so.1.7`。这可能是因为该库文件未正确安装或者未添加到系统的库路径中。
如果你已经安装了 PCL(Point Cloud Library),请确保你已正确安装了该库的版本 1.7,并且该库文件位于正确的路径下。
如果你尚未安装 PCL,可以尝试以下步骤来解决问题:
1. 确定你的系统是否已配置为从正确的源安装软件包。你可以使用以下命令来更新软件包列表:
```
sudo apt update
```
2. 安装 PCL 库及其依赖项。使用以下命令来安装 PCL:
```
sudo apt install libpcl-dev
```
3. 完成安装后,重新编译并运行你的程序,看看是否仍然出现相同的错误。
如果问题仍然存在,你可以尝试将库文件路径添加到系统的库路径中。可以通过以下方式完成:
1. 打开 `/etc/ld.so.conf` 文件进行编辑:
```
sudo nano /etc/ld.so.conf
```
2. 在文件的最后添加以下内容(假设 `libpcl_common.so.1.7` 文件位于 `/path/to/pcl/lib` 目录下):
```
/path/to/pcl/lib
```
3. 保存并关闭文件。
4. 运行以下命令以使更改生效:
```
sudo ldconfig
```
现在,重新编译并运行你的程序,看看问题是否已解决。如果问题仍然存在,请确保你已正确安装了所需的库文件,并且路径配置正确。

error while loading shared libraries: libpcl_segmentation.so.1.14: cannot open shared object file: No such file or directory
根据提供的引用内容,当出现错误"error while loading shared libraries: libpcl_segmentation.so.1.14: cannot open shared object file: No such file or directory"时,可以尝试以下解决方案:
1. 确认库文件是否存在:首先,确认所需的库文件libpcl_segmentation.so.1.14是否存在于系统中。可以使用以下命令来搜索该文件:
```shell
find / -name libpcl_segmentation.so.1.14
```
如果文件不存在,可能需要重新安装或更新相关软件包。
2. 添加库文件路径:如果库文件存在于系统中,但系统无法找到它,可以尝试将库文件路径添加到LD_LIBRARY_PATH环境变量中。使用以下命令将路径添加到环境变量中:
```shell
export LD_LIBRARY_PATH=/path/to/library:$LD_LIBRARY_PATH
```
其中,/path/to/library是库文件所在的路径。
3. 更新动态链接器缓存:如果添加了库文件路径但仍然无法找到库文件,可以尝试更新动态链接器缓存。使用以下命令更新缓存:
```shell
sudo ldconfig
```
请注意,以上解决方案是一般性的建议,具体解决方法可能因系统和环境而异。如果问题仍然存在,建议查阅相关文档或寻求专业支持。
error while loading shared libraries: librally_common.so: cannot open shared object file: No such file or directory
This error occurs when the system is unable to find the required shared library "librally_common.so" in the specified directory. To resolve this issue, you can try the following steps:
1. Check if the library file exists: Verify that the "librally_common.so" file is present in the specified directory. If it is not there, you might need to reinstall the software or library that requires it.
2. Update library paths: If the library file exists but is not found, you can update the library paths using the LD_LIBRARY_PATH environment variable. Set the variable to include the directory where "librally_common.so" is located. For example, you can use the following command:
```
export LD_LIBRARY_PATH=/path/to/library:$LD_LIBRARY_PATH
```
Replace "/path/to/library" with the actual path of the directory containing the library file.
3. Refresh dynamic linker cache: If the library paths are correctly set but the error persists, you can try refreshing the dynamic linker cache using the ldconfig command. Run the following command as root or with sudo privileges:
```
sudo ldconfig
```
4. Reinstall software or library: If none of the above steps work, you might need to reinstall the software or library that is dependent on "librally_common.so". Make sure to follow the installation instructions properly and ensure that all dependencies are satisfied.
If none of these steps solve the issue, please provide more details about your software or library, the steps you have followed, and any other error messages you are encountering.
