whats wrong with this typedef union ( boostC Compiler )

[Rudi]

hi,

i try isolated usb project and not sure why get a compiler error with this
typedef union c code as supplementary:
i use PIC18F2550 - boostC Compiler

i change BYTE in unsigned char in this example.

if i start with an empty PIC18F2550 project
and added this c code in supplementary for using
i get compiler error with 'missing brace'
..

Code: Select all

typedef union
{
    unsigned char    bitmap;
    struct
    {
        unsigned char ep_num:    4;
        unsigned char zero_pkt:  1;
        unsigned char dts:       1;
        unsigned char force_dts: 1;
        unsigned char direction: 1;
    }field;
} TRANSFER_FLAGS;

thanks for help

best wishes

think at code is nothing wrong,
think its the boostC compiler, that do not support Bit Fields.
thanks for help.

Hi Rudi,

One for the Sourceboost forums I believe.

BoostC is not a standard GCC based compiler and by modern standards is a bit of a relic. One of the reasons we are moving to a new compiler for the next Flowcode release. We just have to be careful we don't break things that currently work.
