Navigating Challenges When Compiling C Code with a C Compiler
Compiling existing C code using a C compiler can present numerous potential issues. Here are some common hurdles to anticipate:
Type Strictness:
C enforces stricter type rules compared to C. Assigning an integer directly to a variable with an enumerated type is forbidden in C , while it remains permissible (though discouraged) in C. Therefore, such type conversions may need to be adjusted with explicit casts.
Name Mangling:
Without enclosing C files within "extern C { ... }" blocks, the C compiler will employ name mangling, which can lead to unexpected symbol clashes during linking. To avoid this, C files should be wrapped to preserve C-style naming conventions.
Reserved Words:
Certain words have been designated as reserved keywords in C , including "class," "bool," and "namespace." Using these words as variable names or function names will result in compilation errors.
Additional Concerns:
Gradual Transition Strategy:
When transitioning a large C code base to C incrementally, it is prudent to:
