Recompiling with -fPIC: Resolving Linking Errors

Recompiling with -fPIC is necessary when encountering the error "relocation R_ARM_MOVW_ABS_NC against `a local symbol' can not be used when making a shared object." This error occurs when linking an object file with a restricted symbol, which cannot be used when combined with a shared object.

To successfully address this issue and recompile with -fPIC:

• Disable Static and Dynamic Libraries: Despite the compiler's suggestion, disabling both static and dynamic libraries may be a more direct solution. Select the method that best suits your requirements.
• Enable Shared Libraries: An alternative approach is to enable shared libraries when configuring the software. This can be achieved by adding the --enable-shared option to the ./configure commands, ensuring the compilation of a dynamic library (e.g., .so) instead of a static library (e.g., .a).

By implementing these steps, you can recompile your ffmpeg with -fPIC, thereby resolving the linking error and enabling successful compilation of your program that utilizes the ffmpeg library.
