Hello,
I am building a Nios design using an 16550 Uart. (C++)
The primitives for altera_16550_uart_read are unicode versions.
altera_16550_uart_read(altera_16550_uart_state* sp,
wchar_t* ptr, int len, int flags);
However i would like to use the ansi version:
altera_16550_uart_read(altera_16550_uart_state* sp,
char* ptr, int len, int flags);
I searched header files, compiler settings etc.
=> If i change all wchar_t types to char in the driver source files, the problem is solved for the current application.
However there must be a more elegant way:
=> In the properties of my application, / C/C++ / Preprocessor Include Paths / GNU C++ there is an entry :
_wchar_type__=int. i cannot change this entry. Is it possible to change this entry to char, and will this do the trick ? If so, how can I change this setting? At this time the entry seems to be read only.
=> I looked with the BSP editor at various settings, I could have overlooked someting, but as far as I can see, there are not UNICODE / ANSI strings settings to be found. Is there a way to make the proper settings via the BSP editor?
=> I also looked in stddef.h, but since in C++ wchar_t is a type and not I defined type, i think that the solution for the issue is not there. But i am not sure.
Thanks for any help,
Johi.
