[En-Nut-Discussion] Having some trouble to compile Ethernut

[Ole Reinhardt]

Hello!

Which compiler do you use? Does not look like gcc? 

Your compiler does not preprocessor statements included in a directive.

    outr(EMAC_PIO_PUDR,
#if !defined(PHY_MODE_RMII)
        /* Additionally disable RMII, if not configured. */
        _BV(PHY_COL_RMII_BIT) | 
#endif
        _BV(PHY_RXDV_TESTMODE_BIT) | 
        _BV(PHY_RXD0_AD0_BIT) | _BV(PHY_RXD1_AD1_BIT) |
        _BV(PHY_RXD2_AD2_BIT) | _BV(PHY_RXD3_AD3_BIT) |
_BV(PHY_CRS_AD4_BIT));

Your problem will be fixed, if you remove the #if !defined(...)
statements from within the outr statement and replace it like this:

#if !defined(PHY_MODE_RMII)
        /* Additionally disable RMII, if not configured. */
    #define PHY_MODE_RMII_SETTINGS _BV(PHY_COL_RMII_BIT) 
#else 
    #define PHY_MODE_RMII_SETTINGS 0
endif

    outr(EMAC_PIO_PUDR,
	PHY_MODE_RMII_SETTINGS |
        _BV(PHY_RXDV_TESTMODE_BIT) | 
        _BV(PHY_RXD0_AD0_BIT) | _BV(PHY_RXD1_AD1_BIT) |
        _BV(PHY_RXD2_AD2_BIT) | _BV(PHY_RXD3_AD3_BIT) |
_BV(PHY_CRS_AD4_BIT));

Anyone else has these problems?

Shall I fix it in the trunk?

Regards,

Ole
