[Resolved] Nios II make errors "syntax error" and "already defined"

Altera_Forum · ‎04-20-2010

Hi,

I use Nios II IDE 9.0SP2 (but it is no significant here).

After little modifications on my sources, I had got make errors like this :

--- Quote Start ---

../myproject.c:783: error: invalid initializer

../myproject.c:783: warning: data definition has no type or storage class

../myproject.c:784: error: syntax error before '}' token

After 3 hours of research, clean, copy from sources, reinstall Nios IDE, test on another computer...

I found that all thoses make errors are just due to a little semicolon ';'

    detect_component = IORD_ALTERA_AVALON_PIO_DATA(DETECTION_PIO_BASE); // I have forgot ';' here
    if (detect_component)
    {
        printf("INFO\t: Detected Component ...\n");
    }

I wrote this post in case of someone is looking for those make errors.

Just a little 7-bit character ! :D

To resume : keep cool and simple. Make backups before modifications:)
