    You first need to identify what part of your code is platform dependent and abstract them away the dependencies away. for example, you can using the factory pattern to invoke platform specific calls.

    If you used VC 6, the code is likely MFC. You first step would be standardize the code, for example, rewrite code related to CArray with std::vector and CArchive with std::stream.

    Back in the days I used the book Write Portable Code: A Guide to Developing Software for Multiple Platforms by Brian Hook for guidance. Now you should probably get yourself familiar with the modern C++ standard library first and take a look at QT.

    Thank you reaching out!

     
    I see you're trying to compile a C program that was developed using Microsoft Visual C/C++ 6.0 on a Linux system. While that specific version of MSVC is mainly for Windows, you can still achieve this task by following a few steps with the right tools and compilers on your Linux setup.

     Here’s a general approach you can take:

     1. Install GCC: Most Linux distributions come with the GNU Compiler Collection (GCC) pre-installed, but if it's not installed, you can do so by running:
    sudo apt update
    sudo apt install build-essential

     2. Modify Source Code: Since MSVC and GCC might use different headers or syntax, you might need to make some adjustments to the source code. For example, certain MSVC-specific functions or libraries may not be available in GCC. You might need to replace these with their POSIX equivalents.

     3. Compile the Code: To compile, you can use the following command:  
     gcc -o output_program your_program.c   

    Here, output_program is the name of the compiled executable, and your_program.c is your source file.

     4. Run the Executable: After successful compilation, you can run your program
    using:  ./output_program

     5. Debug as Necessary: If you encounter errors while compiling, pay attention to the error messages, as they often indicate necessary changes to the code.

    To compile a C program developed with Microsoft Visual C/C++ 6.0 on a Linux system, you will need to follow these general steps:

    1. Porting the Code: Since Visual C++ may use Windows-specific APIs, you will need to refactor your code to remove or replace any Windows-specific calls with standard C or POSIX-compliant code. This may involve using libraries that are available on Linux.
    2. Install a C Compiler: Ensure you have a C compiler installed on your Linux system. Common options include GCC (GNU Compiler Collection) or Clang. You can install GCC using your package manager, for example: 
         sudo apt-get install build-essential
    3. Compile the Code: Use the terminal to navigate to the directory containing your C source files. You can compile your program using the GCC compiler with a command like: 
         gcc -o my_program my_program.c
      Replace my_program.c with the name of your source file, and my_program with the desired output executable name.
    4. Run the Program: After compilation, you can run your program using: 
         ./my_program
    5. Debugging: If you encounter errors during compilation, you may need to address them by modifying your code or including necessary libraries.

    This process involves ensuring that your code is compatible with Linux and using the appropriate tools available in the Linux environment.
