Header Hell
Noun · Slang & Abbreviations
Definitions
A painful situation caused by complicated include chains, conflicting declarations, or header management problems, especially in C and C++ ecosystems. In engineering slang, header hell is where build issues become archaeology.
In plain English: A miserable build and maintenance situation caused by header-file complexity.
Example: "The C++ build kept failing in header hell because one platform-specific include order subtly changed the meaning of a shared macro."
