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

Updated: October 2009

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


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).

To set this compiler option in the Visual Studio development environment

  1. Open the project's Property Pages dialog box. For details, see How to: Open Project Property Pages.

  2. Expand the Configuration Properties node.

  3. Expand the C/C++ node.

  4. Select the Advanced property page.

  5. Modify the Use Full Paths property.
