Linking to GDI32 Library in Code::Blocks

In this programming puzzle, the user encountered an undefined reference to the TextOut function while using the GDI32 library.

Problem:

The GDI32 library is a crucial component for many programming applications, but new programmers using Code::Blocks may struggle to connect to it. This user is having this issue despite having the windows.h header, raising the question: How can the GDI32 library be installed and linked to the program?

Solution:

The GDI32 library is already installed on most computers as it's essential for basic program functionality. The issue lies in establishing a connection between the program and the system library. This is achieved through an import library that comes with the compiler.

To link to GDI32:

1. Open the project's settings in Code::Blocks.
2. Navigate to the "Linker settings" tab.
3. Under the "Other linker options" section, specify the library name as "gdi32" (without the ".lib" extension).
4. Ensure that the correct path to the compiler's import library is added to the linker settings.

Additional Notes:

• The "-lgdi32" option can also be used in the linker settings, which is a shorthand for linking to the gdi32 library.
• If the linker option doesn't resolve the issue, it may be necessary to specify the full path to the import library.
• For libraries located in non-standard directories, you can use the "... (browse)" button to locate and select them.
