Visual C++ configuration

Pretranslated C++ code > Delphi RTL/VCL > Visual C++ configuration

For Visual C++ projects following options are recommended:

1. set the x64 option in the menu.

2. Additional dependencies may be:

  version.lib

  mpr.lib

  netapi32.lib

  Rpcrt4.lib

  Dbghelp.lib 

3. set C++ version to C++17

Normally in Visual C++ the  __cplusplus preprocessor macro has a fixed value, but d2c_config uses this value to calculate the used version of C++. Therefore in Visual C++ projects the option:

/Zc:__cplusplus

has to be set in the Additional options pane of the Command Line property page in the properties for C/C++ .

If you are using the big System.Classes, then also set /bigobj, otherwise you get "error C1128". The complete line then looks like:

/Zc:__cplusplus /bigobj

4. If newly translated code is compiled for the first time, it might be useful to disable the warning to "possible loss of data" at type conversions:

C++ -> extended -> deactivate warnings

4244

4267

5. If C++98 code is compiled with Visual C++ you should disable secure warnings

C++ Preprocessor -> preprocessor definitions

_CRT_SECURE_NO_WARNINGS

_SCL_SECURE_NO_WARNINGS

This is not necessary for C++11, because here the secure commands

strcpy_s

strncpy_s

wcscpy_s

etc. are defined.
