  • 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

    http://docwiki.embarcadero.com/RADStudio/Seattle/en/Stricter_C%2B%2B_Compilers_%28Clang-based_C%2B%2B_Compilers%29#Two-Phase_Name_Lookup_in_Templates

    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)
    {

    }

    Unable open  BCBSMP.LIB

    Lib Path Add
