c++10 Seattle Clang error

升级到C++Builder RAD 10 Settle 一些错误解决方法，使用LLVM  CLang编译器，BCC32C

Brush->Color = RGB(49, 106, 197);

TColor cc= 0x333;

clang and c++11 Stricter。

[CLANG Error] ***.cpp(1993): cannot initialize a parameter of type 'System::Uitypes::TColor' with an rvalue of type 'COLORREF' (aka 'unsigned long')
Vcl.Graphics.hpp(390): passing argument to parameter 'Value' here

fix》(TColor)

(TColor)

Brush->Color =(TColor) RGB(49, 106, 197);

TColor cc= (TColor)0x333;

String().sprintf(TEXT("SUM(%s)"), fn);

[CLANG Error] 1.cpp(2156): cannot pass object of non-trivial type 'String' (aka 'System::UnicodeString') through variadic method; call will abort at runtime

fix》c_str()

.c_str()

String ft, fn;
String().sprintf(L"%s %s;", ft.c_str(), fn.c_str());

so like this ok?

String().sprintf(_D("%s"), _D("Hello"));

TParam *pParam, Variant val

pParam->AsBoolean = (bool)val;

[CLANG Error] tt.cpp(2237): ambiguous conversion for C-style cast from 'System::Variant' to 'bool'

fix:

pParam->AsBoolean = val.VBoolean;

 PtInRect Bound

[CLANG Error] WndSpy.cpp(86): taking the address of a temporary object of type 'System::Types::TRect'

PtInRect(&BoundsRect, MousePoint) && hWindow != hOldWindow)

fix》》

TRect arect=BoundsRect;
PtInRect(&arect, MousePoint) && hWindow != hOldWindow)

fix:

用bcc32经典编译器，完整编译OK！

Hide exception variables(-xv) 设置为true试试

fix:

use bcc32c no error,but component not install ok!

use bcc32: compiler error DoGetGestureOptions, switch to bcc32c and switch bcc32 compiler ok!! component install ok!@

add cpp and h file

void __fastcall DoGetGestureOptions(TInteractiveGestures &Gestures, TInteractiveGestureOptions &Options);

void __fastcall ttt::DoGetGestureOptions(TInteractiveGestures &Gestures, TInteractiveGestureOptions &Options)
{

}
