How Do I Resolve the 'undefined reference to TextOut' Error When Linking GDI32 in Code::Blocks?

Linking to Libraries with Code::Blocks: Resolving TextOut Undefined Reference

For aspiring programmers who encounter the "undefined reference to TextOut" error while using the GDI32 library in Code::Blocks, the answer lies in understanding library linking.

Contrary to common belief, GDI32 is a pre-installed library on all computers. The compiler, however, requires an import library to bridge the connection between your program and system files. Import libraries are typically bundled with compilers.

If your compiler lacks import libraries for system libraries, consider downloading the Microsoft Windows Platform SDK.

To link with GDI32 in Code::Blocks, follow these steps:

1. In the Project Build Options window, navigate to the "Linker settings" tab.
2. Under "Libraries," type "gdi32" without the ".a" extension.
3. Ensure that the path to the import library is correct (it may be different for your system).

This approach works seamlessly with MinGW-gcc and all system libraries. For non-system libraries or unusual file locations, provide the full pathname using the "..." button.

This comprehensive guide empowers developers to establish reliable library connections within Code::Blocks, enabling them to effectively utilize the GDI32 library and its functions like TextOut.
