error while loading shared libraries: libg2o_csparse_extension.so
时间: 2023-08-18 07:11:58 浏览: 190
这个错误通常是由于缺少 libg2o_csparse_extension.so 库文件引起的。这个库文件是 g2o 库的一部分,可能是由于没有正确安装或配置 g2o 库导致的。
要解决这个问题,你可以尝试以下几个步骤:
1. 确保你已经正确安装了 g2o 库。你可以通过在终端中运行以下命令来安装 g2o 库:
```
sudo apt-get install libg2o-dev
```
2. 检查库文件是否存在。使用以下命令来查找 libg2o_csparse_extension.so 文件:
```
sudo find / -name libg2o_csparse_extension.so
```
如果找到了库文件,确保它的路径在 LD_LIBRARY_PATH 环境变量中。你可以使用以下命令将其添加到 LD_LIBRARY_PATH 中:
```
export LD_LIBRARY_PATH=/path/to/libg2o_csparse_extension.so:$LD_LIBRARY_PATH
```
3. 如果找不到库文件,可能是由于库文件没有正确链接或安装的问题。你可以尝试重新编译和安装 g2o 库,确保在编译时启用了 csparse_extension 功能。
如果以上步骤都无法解决问题,那么可能是其他配置或依赖项的问题。你可以提供更多关于你的环境和使用情况的信息,以便我能够更好地帮助你解决这个问题。

g2o_viewer: error while loading shared libraries: libg2o_viewer.so: cannot open shared object file: No such file or directory
This error message indicates that the library file "libg2o_viewer.so" cannot be found by the system. Possible reasons for this error could be:
1. The library file is not installed on the system. You may need to install the library file using the package manager of your operating system.
2. The library file is installed but not in the default search path of the system. You may need to add the directory containing the library file to the LD_LIBRARY_PATH environment variable.
3. The library file is installed but its permissions are not set correctly. Make sure that the library file has read and execute permissions for the user running the g2o_viewer program.
To resolve this error, you may need to investigate further to determine the cause of the problem and take appropriate action.
./pose_graph_g2o_lie: error while loading shared libraries: libg2o_core.so: cannot open shared object file: No such file or directory
这个错误提示表明,你的程序在运行时找不到名为libg2o_core.so的共享库文件,因此无法加载./pose_graph_g2o_lie。
解决该问题的方法是确保你的系统中已经安装了g2o库,并且该库的动态链接库文件(.so文件)位于系统的默认搜索路径之一。如果你已经安装了g2o库,但是仍然遇到该问题,可以尝试将库文件的路径添加到LD_LIBRARY_PATH环境变量中,例如:
export LD_LIBRARY_PATH=/path/to/g2o/lib:$LD_LIBRARY_PATH
如果你没有安装g2o库,可以通过以下命令在Ubuntu系统上安装:
sudo apt-get install libg2o-dev
