BUG: 'CXX0017: Error: symbol not found' Compiling with /Zi

 * }

Q115709

1.00 1.50 WINDOWS kbtool kbbuglist -- The information in this article applies to: - The Microsoft C/C++ Compiler (CL.EXE), included with: - Microsoft Visual C++ for Windows, versions 1.0 and 1.5 -- SYMPTOMS ======== Attempting to use the CodeView Display Expression command (?) when debugging code which was compiled with the /Zi switch may cause CodeView to generate the following error message: CXX0017: Error: symbol not found CAUSE ===== The compiler is not emitting the correct symbolic information for the symbol. RESOLUTION ========== You can sometimes avoid the problem by compiling with the /Z7 switch. STATUS ====== Microsoft has confirmed this to be a problem in the Microsoft products listed above. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available. MORE INFORMATION ================ The sample code shown below can be used to illustrate the problem. To reproduce the problem, do the following: 1. Compile the sample code with the /Od and /Zi switches. 2. Load the resulting executable into CodeView. 3. Set a breakpoint on the final closing } of the source code. 4. Run to the breakpoint. 5. Open the Command window in CodeView and enter the following command: ?Function( x.a == 1 && ::X == 5 ),s 6. Press enter. This should cause CodeView to call Function with the result of the expression ( x.a == 1 && ::X == 5 ) as an argument. The value returned by Function should be displayed as a string. However, CodeView instead issues the CXX0017 error message. Compiling the same code with /Od /Z7 and following steps 2 through 6 listed above causes CodeView to correctly display the string "PASSED" as the return from Function. Sample Code --- /* Compile options needed: /Od /Zi */ char * Function( int Condition ); int X(void) { return 5; } void main( void ) { struct X { int a; }; X x; x.a = 1; { struct X { int b; }; X y; y.b = 2; } } char * Function( int Condition ) { if( Condition ) return "PASSED"; else return "FAILED"; } Additional reference words: 1.00 1.50 4.10 8.00 8.00c KBCategory: kbtool kbbuglist KBSubcategory: CLIss
