Victor,
I believe that the crux of the problem lies in the fact that C++
compilers tend not to like implicit casts (such as (void *)) which are
leftover from C, as much as they like the explicit conversions:
const_cast
dynamic_cast
reinterpret_cast
static_cast
In your situation I would go ahead and try a reinterpret_cast<void *>,
instead of just using (void *). Hope this helps.

I am seeking the most straightforward way to apply the BIGMEM patch to
the 2.2.16 kernel. (I'm running Red Hat 7.0). I seek to increase my
program's virtual address space to 2 GB.
A download with subsequent instructions would be ideal.

It might be the response to a "divide by zero", but I would hope
that FP exceptions were better handled. Quite possibly it is your
data, and different machines handle FP numbers slightly differently.
A matrix with a near-zero determinant can cause big trouble.
Otherwise, do you have enough swap enabled? Some machines will
segfault when they run out of VM to allocate, even if it's
never used.

It might be. Anything is possible. Have you checked your memory
with memtest-86? You might also try my utilities below.

On any architecture that implements IEEE754 FP (which I think includes
every architecture with an FPU supported by Linux) you shouldn't need
to mess around with floating point formats. FP values will already be
in the right format, so you just need to take care of the byte order
issue.
You probably ought to at least look at some existing XDR code. For
example, the XDR code in glibc assumes IEEE754, so to encode a double
it simply does (in sunrpc/xdr_float.c:xdr_double):
long *lp = (long *)dp;
return (XDR_PUTLONG(xdrs, lp+!LSW) &&
XDR_PUTLONG(xdrs, lp+LSW));
(LSW is a macro that is 1 for a big-endian system, 0 for
little-endian).
The glibc code, like most other XDR code I've seen, is derived from
the ONC RPC code Sun released many years ago. The Sun code supported
non-IEEE754 architectures also.
That Sun code was released under the BSD license, so you ought to be
able to reuse it, if it meets your requirements. Though it is
probably better and easier to re-use a maintained derivative of it,
e.g. glibc if you can live with the GPL, or the sunrpc code from *BSD
otherwise. (Actually, looking at the code in glibc, I can't find
anything to indicate that it isn't still be BSD licensed. Check for
yourself.)

RedHat 7.0 comes with a kernel-enterprise package, with has a kernel
built with the BIGMEM patch. Install that.

Linux normally gives processes a virtual address space of 3GB. What
do you mean "increase"?

By default. Have a look at /usr/src/linux/include/asm-i386/processor.h, and
find the line
#define TASK_UNMAPPED_BASE (TASK_SIZE / 3)
Changing that to, for example,
#define TASK_UNMAPPED_BASE (TASK_SIZE / 12 * 10)
will have the kernel start doing mmaps (and thus library-loads) at
0xa0000000. Adjust as needed.

Subject: Automatically loading SCSI module
Date: 18 Jan 2001 01:15:12 -0500
Reply-To: [EMAIL PROTECTED]
I have a SCSI card (an old Adaptec 152x) with a SyQuest drive hanging
off of it. There's nothing else on the SCSI card.
I have built my kernel (2.2.18) to include support for this card as a
module (aha152x.o). I have also built SCSI disk support, etc., all as
modules.
I have added this to my /etc/modules.conf file:
options aha152x aha152x=0x340,9
alias scsi_hostadapter aha152x
(these options are required to use the card). I have added this to my
/etc/fstab file:
/dev/sda1 /syext ext2 noauto,user 0 0
Now, what I want to happen is that I just say:
# mount /syext
and Linux will automatically load the aha152x module with the proper
configuration. But, that's not happening. When the module is not
loaded and I try the above mount command, I get:
mount: /dev/sda1 is not a valid block device
If I load the module by hand using "insmod 152x", _then_ it all works
fine and I can mount the filesystem on /dev/sda1, use it, whatever.
If I use "modprobe scsi_hostadapter", then the 152x module is also
loaded correctly in that case.
What do I need to do to convince Linux to load that module when I try to
mount /dev/sda1? I thought the kmod daemon (which I do have all that
support enabled in my kernel) was supposed to managte all that; the
kernel proper calls the kmod code to resolve the issu, and it calls
modprobe with proper arguments, and problem solved.
What am I missing here?

With Linux, you get all the tools necessary to find out.
Since you have the binary and a core dump, use gdb to determine where
and why the program crashed.
Trying to analyse a problem with a program we don't know and a "random
error" requires state-of-the-art crystal balls and they are waaaay to
expensive.

AFAIK, autoloading does not work on SCSI host adapter drivers.
You need to load them explicitly by either building a (new) initrd or
adding an "insmod 152x" to rc.sysinit or the like.
