Compiler Warning (level 1) C4964

  • Artikkeli

No optimization options were specified; profile info will not be collected

/GL and /LTCG were specified, but no optimizations were requested, so no .pgc files will be generated and, therefore, no profile-guided optimizations will be possible.

If you want .pgc files to be generated when you run your application, specify one of the /O compiler options.

The following sample generates C4964:

// C4964.cpp
// compile with: /W1 /GL /link /ltcg:pgi
// C4964 expected
// Add /O2, for example, to the command line to resolve this warning.
int main() {
   int i;
}
