How to Fix No Symbol Table is Loaded Error: Practical Solutions with the File Command

If you are a developer, you might have faced the "No symbol table is loaded" error while debugging your code. This error can be frustrating and can slow down your debugging process. In this guide, we will discuss practical solutions for this error using the "file" command.

What is the "No Symbol Table is Loaded" Error?

The "No symbol table is loaded" error occurs when there is no symbol table in the executable file or shared library. The symbol table is essential for debugging your code as it contains information about the functions and variables used in your program.

Solution 1: Use the "file" Command

The "file" command is a powerful Linux command that can provide information about the type of file you are dealing with. It can also tell you if the file has a symbol table or not. To use the "file" command, follow these steps:

1. Open your terminal.
2. Navigate to the directory where your executable file or shared library is located.
3. Type the following command:

file <filename>

Replace <filename> with the name of your executable file or shared library.

1. The output of the command will tell you if the file has a symbol table or not. If the file has a symbol table, you can proceed with debugging your code.

Solution 2: Compile Your Code with Debugging Symbols

If your executable file or shared library does not have a symbol table, you can compile your code with debugging symbols. Debugging symbols are pieces of information that are added to your code during the compilation process. These symbols contain information about the functions and variables used in your program.

To compile your code with debugging symbols, follow these steps:

1. Open your terminal.
2. Navigate to the directory where your code is located.
3. Type the following command:

gcc -g <filename>.c -o <filename>

Replace <filename> with the name of your code file.

1. The -g option tells the compiler to include debugging symbols in the executable file or shared library.
