The first error:
error while loading shared libraries: libctemplate.so.3: cannot open shared object file: No such file or directory
Solution:
This error message indicates that your program cannot find a shared library file named "libctemplate.so.3" at runtime, so the library file cannot be loaded. This may be because the library file is not installed correctly or is not configured correctly.
To solve this problem, you can try the following steps:
1. Check whether the library file has been installed. You can use the following command to search for the library file:
sudo find / -name "libctemplate.so.3"
If the library is already installed, it should show up in the search results. If the library file is not found, it needs to be installed.
2. If the library file is already installed, you can try to add its path to the LD_LIBRARY_PATH environment variable. You can use the following command to add the library file path to LD_LIBRARY_PATH:
Replace /path/to/libctemplate.so.3 with the address found in the first step
export LD_LIBRARY_PATH=/path/to/libctemplate.so.3:$LD_LIBRARY_PATH
3. If none of the above methods can solve the problem, you can try to reinstall the library file. You can reinstall the library with the following command:
sudo apt-get install libctemplate3
The second error:
error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory
This error message means that your program cannot find the shared library file named libmysqlclient.so.18 at runtime, so it cannot load the library file. This may be because the library file is not installed correctly or is not configured correctly.
To solve this problem, you can try the following steps:
1. Check whether the library file has been installed. You can use the following command to search for the library file:
sudo find / -name "libmysqlclient.so.18"
If the library is already installed, it should show up in the search results. If the library file is not found, it needs to be installed.
2. If the library file is already installed, you can try to add its path to the LD_LIBRARY_PATH environment variable. You can add the library file path to LD_LIBRARY_PATH with the following command:
export LD_LIBRARY_PATH=/path/to/libmysqlclient.so.18:$LD_LIBRARY_PATH
This will allow the system to find the library file when running the program.
3. If none of the above methods can solve the problem, you can try to reinstall the library file. You can reinstall the library with the following command:
sudo apt-get install libmysqlclient-dev
If you are using other Linux distributions, you need to use the corresponding package manager to install the library file.
