At the moment, Boost.Regex has an incompatibility with the VCL headers when
compiling with Borland C++ 5.5. Simply having
#include <vcl.h> #include <boost\regex.hpp>
generates a large number of errors of the type.
[C++ Error] cregex.hpp(91): E2015 Ambiguity between '_fastcall operator |(int,const Variant &)' and '|'
I'm afraid that I have yet to track down the precise cause of the errors, or
a solution.
I had once a problem like the one described and was due to the operator|() being overloaded for an enum type. (compiler: BCB 5.5.1)
For example the code below
//-----Start of code
enum SquareAngle
{
Rotate0,
Rotate90,
Rotate180,
Rotate270,
Rotate360
} ;SquareAngle operator*(SquareAngle lhs, SquareAngle rhs)
{
return static_cast<SquareAngle>((static_cast<int>(lhs) +
static_cast<int>(rhs)) % static_cast<int>(Rotate360)) ;
}
#include <vcl.h> #pragma hdrstop
#include "OperatorOverloadForm.h"
//-------------------------------------------------------------------------- -
#pragma package(smart_init)
#pragma resource "*.dfm"
TForm1 *Form1;
//-------------------------------------------------------------------------- -
__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
}
//----End of code
produces the following error:
[C++ Error] sysset.h(24): E2015 Ambiguity between '_fastcall operator /(int,const Currency &)' and '/'
plus others...
Any workarounds? I sbstituted the operator*() with a normal function...
