/FC (Full Path of Source Code File in Diagnostics)

Causes the compiler to display the full path of source code files passed to the compiler in diagnostics.

Syntax

/FC

Remarks

Consider the following code sample:

// compiler_option_FC.cpp
int main( ) {
   int i   // C2143
}

Without /FC, the diagnostic text would look similar to this diagnostic text:

• compiler_option_FC.cpp(5) : error C2143: syntax error : missing ';' before '}'

With /FC, the diagnostic text would look similar to this diagnostic text:

• c:\test\compiler_option_fc.cpp(5) : error C2143: syntax error : missing ';' before '}'

/FC is also needed if you want to see the full path of a file name when using the __FILE__ macro. See Predefined Macros for more information on __FILE__.

The /FC option is implied by /ZI. For more information about /ZI, see /Z7, /Zi, /ZI (Debug Information Format).

/FC outputs full paths in lower case.
