Hey
Ive just been trying to build the latest develoment snapshot (4.3.99.9)
and have come across an error in the compiling.
xf86DDC.c: In function `DDCRead_DDC2':
xf86DDC.c:336: error: invalid lvalue in assignment
make[6]: *** [xf86DDC.o] Error 1
make[6]: Leaving directory
`/var/tmp/portage/xfree-4.3.99.9/work/xc/programs/Xserver/hw/xfree86/ddc'
I cant seem to find much on this at all, except the offending code which is
the line marked with !!!! in the following procedure from xf86DDC.c
static unsigned char *
DDCRead_DDC2(int scrnIndex, I2CBusPtr pBus, int start, int len)
{
I2CDevPtr dev;
unsigned char W_Buffer[2];
int w_bytes;
unsigned char *R_Buffer;
int i;
xf86LoaderReqSymLists(i2cSymbols, NULL);
!!!! if (!dev = xf86I2CFindDev(pBus, 0x00A0)) {
dev = xf86CreateI2CDevRec();
dev->DevName = "ddc2";
dev->SlaveAddr = 0xA0;
dev->ByteTimeout = 2200; /* VESA DDC spec 3 p. 43 (+10 %) */
dev->StartTimeout = 550;
dev->BitTimeout = 40;
dev->ByteTimeout = 40;
dev->AcknTimeout = 40;
dev->pI2CBus = pBus;
if (!xf86I2CDevInit(dev)) {
xf86DrvMsg(X_PROBED,scrnIndex,"No DDC2 device\n");
return NULL;
}
}
if (start < 0x100) {
w_bytes = 1;
W_Buffer[0] = start;
} else {
w_bytes = 2;
W_Buffer[0] = start & 0xFF;
W_Buffer[1] = (start & 0xFF00) >> 8;
}
R_Buffer = xcalloc(1,sizeof(unsigned char)
* (len));
for (i=0; i<RETRIES; i++) {
if (xf86I2CWriteRead(dev, W_Buffer,w_bytes, R_Buffer,len)) {
if (!DDC_checksum(R_Buffer,len))
return R_Buffer;
#ifdef DEBUG
else ErrorF("Checksum error in EDID block\n");
#endif
}
#ifdef DEBUG
else ErrorF("Error reading EDID block\n");
#endif
}
xf86DestroyI2CDevRec(dev,TRUE);
xfree(R_Buffer);
return NULL;
}
Does anyone have any ideas?
