Summary: compile errors on Alpha platform
Product: prim54
Version: 1.0.2.2
Platform: alpha
OS/Version: Linux 2.4
Status: ASSIGNED
Severity: normal
Priority: P2
Component: Device Driver
AssignedTo: prism54-devel@prism54.org
ReportedBy: john-and-kathy@shaw.ca
Building cvs snapshot from 2004 01 13 on Alpha platform fails with
messages below (they are fatal on a 64-bit platform). This is on 2.4.24
kernel from kernel.org. Using HP (Redhat 7.2) platform, gcc is version 2.96.
The interesting ones are islpci_mgt.c because they use (u32) pointers. The
rest are alignment calculations as far as I can tell.
The bugs regarding unistd/waitpid and unistd/close can be fixed by moving
the include for linux/unistd.h down below the include asm/uaccess.h. Whether
this is in fact good practise is another matter; I do not know.
The bugs for warning: cast to pointer from integer might be fixed by a "better"
choice of type for the variables "source" and "destination" in routine
islpci_mgt_queue (not u32 but something more platform-dependant like u_long
might be better). I haven't tried it yet myself; counting "u32" in the source
is a little daunting.
See de4x5.c for example of an Alpha-capable driver.
Here is the output of the make:

------- Additional Comments From Jens.Maurer@gmx.net 2004-01-26 23:41 -------
Thank you for your detailed bug report.
The <linux/unistd.h> appears not to be required/used. I've removed it in the
current CVS. The warnings from islpci_eth.c should be gone in recent CVS.
The warnings from islpci_mgt.c will be removed by the CVS mgmt_rework branch.
(This branch doesn't have the other fixes, though).
Please try again, and tell me if there are less errors.
