Description 

Build Configuration 

Displays the active build configuration. Use the drop-down menu to select another build configuration.  

Save As... 

Displays the Save As dialog box to save the current configuration's options to a file that can be loaded as a named option set.  

Load...

C++ Compatibility options 

Description 

Non-const calls for const object (-Vbn) 

Allow calling a non-const member function for a const object. Default = false  

Old overload resolution (-Vbo) 

Use old overload resolution rules. Default = false  

Non-const reference binding (-Vbr) 

Allow non-const reference binding. Default = false  

Explicit template specialization as member function (-Vbx)  

Allow explicit template specializations as member functions. Default = false  

Old-style explicit template specialization (-Vbe) 

Allow old-style explicit template specialization. Default = false  

Old style class arguments (-Va) 

Supports old style class arguments. Default = false  

Constructor displacements (-Vc) 

Supports constructor displacements. Default = false  

Old for-statement scoping (-Vd) 

Specifies the scope of variables declared in for loop expressions. The output of the following code segment changes, depending on the setting of this option.
int main(void)
{
for(int i=0; i<10; i++)
{
cout << "Inside for loop, i = " << i
<< endl;
} //end of for-loop block
cout << "Outside for loop, i = " << i <<
endl; //error without -Vd
} //end of block containing for loop
If this option is disabled (the default), the variablei goes out of scope when processing reaches the end of the for loop. Because of this, you'll get an Undefined Symbol compilation error if you compile this code with this option disabled.
If this option is set (-Vd), the variable i goes out of scope when processing reaches the end of the block containing the for loop. In this case, the code output would be:
Inside for loop, i = 0
...
Outside for loop, i = 10
Default = false  

Old Borland class layout (-VI) 

This is a backward compatibility switch that causes the C++ compiler to lay out derived classes the same way it did in older versions of C++Builder. Enable this option if you need to compile source files that you intend to use with older versions of C++Builder (for example, if you need to work with a DLL that you cannot recompile, or if you have older data files that contain hardwired class layouts). Default = false  

Push 'this' first (-Vp) 

Like Pascal, pushes 'this' first. The compiler typically pushes parameters on the stack from right to left. Default = false  

VTable in front (-Vt) 

Puts virtual table pointer at front of object layout. Default = false  

'Slow' virtual base pointers (-Vv) 

Uses 'slow' virtual base pointers. Default = false  

Zero-length empty class member functions (-Vx) 

Usually the size of a data member in a class definition is at least one byte. When this option is enabled, the compiler allows an empty structure of zero length. Default = false  

Zero-length empty base class (-Ve) 

Usually the size of a class is at least one byte, even if the class does not define any data members. When you set this option, the compiler ignores this unused byte for the memory layout and the total size of any derived classes; empty base classes do not consume space in derived classes. Default = false  

General option 

Description 

Default 

Saves the current settings as the default for each new project.
