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

[Dominik Schröder]

Thanks for your answer!

I have found my problem. Some months ago I added two Flags in
\nut\Makevars.gcc:
-O0 -pedantic -std=gnu99

I think -pedantic was the Problem...
Is there any chance to use -pedantic and compile Ethernut!?

I will change the code in your ways and try again to compile...

Best regards

Dominik Schröder

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
