Data Member Alignment - How can I use the variable alignment attribute? Audit

Question

Accepted Answer

Question: 
 I have a C++ header file with class declaration. Part of the declaration is a data member. 
 
 int a; 
 
 I need to ensure correct alignment. According to documentation I should be able to do the following. 
 int a __attribute__ ((aligned (8))); 
 However, I get an error. 
 
 ".\foo.h", line 92: cc0065: error: expected a ";" int a __attribute__ ((aligned (8))); ^ 
 
 How can I use the variable alignment attribute? 
 =============================== 
 Answer: 
 The GCC compatibility extensions are only available in C89 and C99 modes.They are not accepted in C++ dialect mode, unless enabled with the -g++ switch". So please add '-g++' switch in to compiler > additional options in your C++ project before the build. 
 Please refer the CCES help path for more details. CrossCore Embedded Studio 2.x.x > SHARC Development Tools Documentation > C/C++ Compiler Manual for SHARC Processors > Compiler > C/C++ Compiler Language Extension
