Troubles with compiling expressions with static_cast (C++) in newer Keil IDE

Nikolay Baklanov

Hallo, All!

These days I have migrated to newer Keil IDE version and found my older C++ project can not be compiled anymore. The IDE is installed and licenced correctly. If I return back to older version, everything is being compiled just perfectly.

Can anybody say what is wrong with my configuration (I reuse the same project) or with latest Keil version:

IDE-Version:
µVision3 V3.53
Copyright (c) Keil Elektronik GmbH / Keil Software, Inc. 1995 - 2007
Tool Version Numbers:
EC++ Compiler:      EC166.Exe      V1.09b
C Compiler:         C166.Exe       V6.09a
Assembler:          A166.Exe       V5.30
Linker/Locator:     L166.Exe       V5.22
Librarian:          LIB166.Exe     V4.26
Hex Converter:      OH166.Exe      V4.7a
CPU DLL:            S166.DLL       V2.54
Dialog DLL:         D167.DLL       V2.48a
Target DLL:         MONITOR\MON166.DLL       V2.42
Dialog DLL:         T167.DLL       V2.48

This tool-chain refuses to compile the source code (C++) containing expressions like:

 ...
 return static_cast <unsigned int> (myVar);
 ...

saying

 error: Embedded C++ does not support the new cast syntax

THIS IS STRANGE since I used to use older version of Keil:

IDE-Version:
µVision3 V3.21
Copyright (c) Keil Elektronik GmbH / Keil Software, Inc. 1995 - 2005
Tool Version Numbers:
EC++ Compiler:      EC166.Exe      V1.09
C Compiler:         C166.Exe       V6.02
Assembler:          A166.Exe       V5.20
Linker/Locator:     L166.Exe       V5.21
Librarian:          LIB166.Exe     V4.26
Hex Converter:      OH166.Exe      V4.7a
CPU DLL:            S166.DLL       V2.49
Dialog DLL:         D167.DLL       V2.45
Target DLL:         MONITOR\MON166.DLL       V2.41
Dialog DLL:         T167.DLL       V2.45

which has no problem when compiling the project.

What am I missing?

Thanks,
Nikolay.
