Error While Compiling with ffmpeg: "Relocation R_ARM_MOVW_ABS_NC against `a local symbol' can not be used when making a shared object; recompile with -fPIC"

While attempting to reinstall ffmpeg on an ARM Ubuntu system, a compilation error was encountered when using a program that utilized the ffmpeg library. The error message indicated:

/usr/bin/ld: /usr/local/lib/libavcodec.a(amrnbdec.o): relocation R_ARM_MOVW_ABS_NC against `a local symbol' can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/libavcodec.a: could not read symbols: Bad value
collect2: ld returned 1 exit status

This error arises from an attempt to link a static library (.a) with a dynamic one (.so). To resolve this issue, it is necessary to recompile ffmpeg with the -fPIC flag.

Recompiling with -fPIC

Adding the --enable-shared flag during ./configure will instruct ffmpeg to build as a dynamic library. Alternatively, you can choose to disable static libraries completely if preferred.

Once the ffmpeg library has been recompiled with -fPIC, the compilation should proceed successfully without the aforementioned error.

Mastering Polymorphism in C : A Deep DiveMay 14, 2025 am 12:13 AM

Mastering polymorphisms in C can significantly improve code flexibility and maintainability. 1) Polymorphism allows different types of objects to be treated as objects of the same base type. 2) Implement runtime polymorphism through inheritance and virtual functions. 3) Polymorphism supports code extension without modifying existing classes. 4) Using CRTP to implement compile-time polymorphism can improve performance. 5) Smart pointers help resource management. 6) The base class should have a virtual destructor. 7) Performance optimization requires code analysis first.

C and XML: Integrating Data in Your ProjectsMay 10, 2025 am 12:18 AM

Integrating XML in a C project can be achieved through the following steps: 1) parse and generate XML files using pugixml or TinyXML library, 2) select DOM or SAX methods for parsing, 3) handle nested nodes and multi-level properties, 4) optimize performance using debugging techniques and best practices.

Using XML in C : A Guide to Libraries and ToolsMay 09, 2025 am 12:16 AM

XML is used in C because it provides a convenient way to structure data, especially in configuration files, data storage and network communications. 1) Select the appropriate library, such as TinyXML, pugixml, RapidXML, and decide according to project needs. 2) Understand two ways of XML parsing and generation: DOM is suitable for frequent access and modification, and SAX is suitable for large files or streaming data. 3) When optimizing performance, TinyXML is suitable for small files, pugixml performs well in memory and speed, and RapidXML is excellent in processing large files.

C# and C : Exploring the Different ParadigmsMay 08, 2025 am 12:06 AM

The main differences between C# and C are memory management, polymorphism implementation and performance optimization. 1) C# uses a garbage collector to automatically manage memory, while C needs to be managed manually. 2) C# realizes polymorphism through interfaces and virtual methods, and C uses virtual functions and pure virtual functions. 3) The performance optimization of C# depends on structure and parallel programming, while C is implemented through inline functions and multithreading.

C XML Parsing: Techniques and Best PracticesMay 07, 2025 am 12:06 AM

The DOM and SAX methods can be used to parse XML data in C. 1) DOM parsing loads XML into memory, suitable for small files, but may take up a lot of memory. 2) SAX parsing is event-driven and is suitable for large files, but cannot be accessed randomly. Choosing the right method and optimizing the code can improve efficiency.

C in Specific Domains: Exploring Its StrongholdsMay 06, 2025 am 12:08 AM

C is widely used in the fields of game development, embedded systems, financial transactions and scientific computing, due to its high performance and flexibility. 1) In game development, C is used for efficient graphics rendering and real-time computing. 2) In embedded systems, C's memory management and hardware control capabilities make it the first choice. 3) In the field of financial transactions, C's high performance meets the needs of real-time computing. 4) In scientific computing, C's efficient algorithm implementation and data processing capabilities are fully reflected.

Debunking the Myths: Is C Really a Dead Language?May 05, 2025 am 12:11 AM

C is not dead, but has flourished in many key areas: 1) game development, 2) system programming, 3) high-performance computing, 4) browsers and network applications, C is still the mainstream choice, showing its strong vitality and application scenarios.
