Date: Sat, 02 Sep 2000 22:21:04 +0000
Hello,
I understand (allmost) everything from the "linux module programming guide",
but I can't compile all but the most simple modules. Here's a sample of what
doesn't work:
#include <linux/kernel.h>
#include <linux/module.h>
#if CONFIG_MODVERSIONS==1
#define MODVERSIONS
#include <linux/modversions.h>
#endif
#include <linux/proc_fs.h> /* Causes the problem */
int init_module() { return 0; }
void cleanup_module() {}
I compile with the following flags (gcc 2.7.2.3, as suggested): -0
-D__KERNEL -DMODULE -DLINUX
The linux/proc_fs.h messes everything up: i get tons of errors (really!) on
ridiculous errors like "parse error before clock_t in
/usr/include/linux/time.h". When I go and look at those supposed errors,
I can't find any... (btw the problem occurs with other headers too....)
I'm using kernel 2.4.0test4 (When using 2.2.16 I just got some warnings with
-Wall turned on, but the compiling worked. I only couldn't insert the
module.)
Is this a) a kernel problem (not very likely), b) a gcc problem (not very
likely), c) my own fault (very likely)?
Any help - or guidance would be appreciated a lot!
thanks.
Joris Vankerschaver

There's alot of "lively" discussion of this issue, but the bottom line
is don't hold your breath. Right now, I'm looking at a tentative plan
to make a go at it in 2.5. I want to wait until 2.4 is stable and out
for a bit to avoid dumping too much on people's plates though.

You can give that up too. CLONE_PID isn't usable from user space. For
right now, your best bet is to replace Linux with FreeBSD.

In order to add any dso modules to php, you have to have the apxs rpm
installed. During your installation of Redhat you must not have
choosen this option. I think that you can recover by downloading the
rpm and starting the process all over again. it is probably named
apxs /apache or some derivation of those words(it may even be on your
cd).
Hope this helps.

Date: Sun, 03 Sep 2000 00:47:36 GMT
hi,
I just built this kernel on RH6.1
Everything was fine until i did "shutdown -r now"................
The system hung at the point where it said it cannot unmount /proc
because automount is not present.
Then, I rebuild the kernel with automount enabled, now it cannot
recognize partitions /dev/hda5, 6, 7, 8, 9
can somebody suggest why?
thanks

the mmap interface is 32 bit. you would have to use mmap64 to address bigger
areas of memory. try and avoid going back to the segmented model.

Date: Mon, 28 Aug 2000 19:44:17 +0200
Hi,
documentation of code is nice, but too much is not good. It can
confuse sometimes. Make shure that your file is executable
(chmod a+x filename). Invoking the perl interpreter should
happen in the first line and not in the second.
Otherwise your code is treated like a shell scipt. It would be a
good idea to test your code before you put it in the rc.d startup
scripts. I doubt that you can execute it on the command line
with ./filename?
Try:
#!/usr/bin/perl
...
Hope that helps,
Frank

The latter arp is rejected because at that point the original pending arp
request has been resolved and an entry exists in the arp table.
Two are probably being sent because proxy arp is enabled.

"Cheap" seems to be the operative rule, at least in the C language.

Hi,
when compiling my kernel (2.2.12) I set all the options using one of
the config programs (xconfig) compile it, and
copy it to /boot directory... I add a new entry in the lilo.conf file to
run this kernel.
When the kernel starts I get this error message:
mounting filesystem - type devpts not supported.
This doesn't seem to cause any trouble, everything runs fine.. I'd just
like to know what it is and what config option changes it.
thanks
dan.

Have you got the latest modutils? The arrangement of the modules
directories has changed. I am running this kernel, and modules
work fine (mostly; I had to do something special for sound).
modutils I have is:
$ rpm -qv modutils
modutils-2.3.14-2
