Compiler Error C2732

linkage specification contradicts earlier specification for 'function'

Remarks

The function is already declared with a different linkage specifier.

This error can be caused by include files with different linkage specifiers.

To fix this error, change the extern statements so that the linkages agree. In particular, do not wrap #include directives in extern "C" blocks.

Example

The following example generates C2732:

// C2732.cpp
extern void func( void );   // implicit C++ linkage
extern "C" void func( void );   // C2732
