Appreciate any help to resolve the following compiling error. Liu

Compiling Error:

main.c: In function 'AOC_pci_request_regions':
main.c:>>>: error: dereferencing pointer to incomplete type
main.c:>>>: error: dereferencing pointer to incomplete type

Source Code:

static int AOC_pci_request_regions( device_t dev, const char *res_name )
{
int i,j;
int rid;
int bar;
struct resource_list_entry *rle;
struct pci_devinfo *dinfo;
struct resource_list *rl;

for ( i = 0; i <= PCIR_MAX_BAR_0; i++ ) 
{
bar = PCIR_BAR( i );
dinfo = device_get_ivars( dev );
>>> rl = &dinfo->resources;
rle = resource_list_find(rl,SYS_RES_MEMORY,i);
if( rle == NULL )
{
dinfo = device_get_ivars(dev);
>>> rl = &dinfo->resources;
rle=resource_list_find(rl,SYS_RES_IOPORT, i);
};

if( rle == NULL )
return (-ENODEV);
};

You most probably forgot to include some headers.

xibo,

Thanks.

Do you know where struct resource_list is defined? I searched the whole /usr/src and could not locate it.

Sincerely,
Liu

I don't know anything about this, but from

% grep -ir "resource_list" /usr/include

I see:

./machine/nexusvar.h:   struct resource_list    nx_resources;

jrm,

Thanks.

Yes, nx_resources is declared as struct resource_list" The structure resource_list looks defined no where.

Sincerely,
Liu
