Using the df command or the statfs and fstatfs system calls in a program.
By the way, you might want to see the new thread in this newsgroup about
enlarging your disk size by 4 inches. ;)

libc5 was ELF. You will need the libc4 libraries.

Subject: dynamic linker problem
Date: Sun, 18 Jun 2000 08:30:13 GMT
Hi,
I got some problems configuring kernel 2.2.16 on my linux box, when I
did "make xconfig" it gave me this error message. (I could manage to
upgrade my kernel before (from 2.2.5 to 2.2.15)):
[root@spica linux] make xconfig
rm -f include/asm
( cd include ; ln -sf asm-i386 asm)
make -C scripts kconfig.tk
make[1]: Entering directory `/usr/src/linux/scripts'
gcc -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -c -o tkparse.o
tkparse.c
cpp: -lang-c: linker input file unused since linking not done
BUG IN DYNAMIC LINKER ld.so: dynamic-link.h: 57: elf_get_dynamic_info:
Assertion `! "bad dynamic tag"' failed!
make{1}: ***[tkparse.o] Error 1
make[1]: Leaving directory `/usr/src/linux/scripts'
make: ** [xconfig] Error 2
I tried to upgrade ld.so to version 1.9.9 but the upgrade failed and gave
me a similar message.
Could anyone tell me the what the problem is and how to solve it ?
Software version :
- egcs 1.1.2
- gcc --version 2.91.66
- ld.so 1.9.5
- binutils-2.9.5.0.22-6
- Redhat 6.0
- kernel 2.2.15
Any help will be appreciated
Thanks,

Whoops, I stand corrected. Shows you how long it's been since I used
the a.out format. My earlier post obviously should have said you'll
need to download an install libc4. Searching the RedHat CD for them
would be fruitless.

Subject: Calling ide ioctl from a driver
Date: Sun, 18 Jun 2000 15:53:30 +0100
I have written a device driver and ancillary programs for Toshiba laptops
that enables you to control all the power saving features of the laptop.
The problem is that a couple of models don't support setting the hard drive
standby time. What I would like to do is emulate the Toshiba power
saving calls for the models that don't support them by using the
standard IDE hard drive standby feature.
You can set this with an ioctl on /dev/hda, but this of course requires
write permission on /dev/hda which either requires root permission or
giving rather too much permission on /dev/hda.
If figure that I can call ide_ioctl directly from within the kernel,
but how do I get the struct inode and struct file parameters when in
the kernel?
JAB.

Subject: process cpu time
Date: 18 Jun 2000 13:46:11 GMT
I'm trying to devise a method, from within a shell program, to determine
if a specific process is hung or not. What I'm thinking of doing is
checking the amount of cpu time the process has used, sleep for several
minutes and then check again to see if that has increased or not.
I suspect I can do this by parsing one of the pseudo files under
/proc/PID (where PID represent the process ID of the process to checked).
Which pseudo file would tell me this and where within that file?
Thanks.

Hi,
I am having some problems getting the Accerlearted GL code working on
my Linux box. I am running kernel 2.2.15 with glibc 2.0 (an upgrading
SuSE 6.1 distribution). I have successfully installed XFree 4.0 and
got everything working. I then installed Mesa 3.2 and got the libraries
compiled and all the demos running. I then downloaded the NVIDIA kernel
module and GLX drivers version 0.9-3 to run on my diamond viper 550
(TNT) card. I installed all the kernel modules and the GL libs from
the tarball distribution (taking care to rename old GL files). The
X server works fine. The problems start when I try to compile the
Mesa xdemo "glxinfo" with these libraries. I get the following output;
gcc -I../include glxinfo.c -L../lib -lglut -lGLU -lGL -o glxinfo
/usr/lib/libGL.so: undefined reference to `dlsym@@GLIBC_2.0'
/usr/lib/libGL.so: undefined reference to `dlerror@@GLIBC_2.0'
/usr/lib/libGL.so: undefined reference to `dlclose@@GLIBC_2.0'
/usr/lib/libGL.so: undefined reference to `dlopen@@GLIBC_2.1'
collect2: ld returned 1 exit status
I have tried including -ldl but still get;
gcc -I../include glxinfo.c -L../lib -lglut -lGLU -lGL -ldl -o glxinfo
/usr/lib/libGL.so: undefined reference to `dlsym@@GLIBC_2.0'
/usr/lib/libGL.so: undefined reference to `dlerror@@GLIBC_2.0'
/usr/lib/libGL.so: undefined reference to `dlclose@@GLIBC_2.0'
/usr/lib/libGL.so: undefined reference to `dlopen@@GLIBC_2.1'
collect2: ld returned 1 exit status
Does anyone recognise the mistake Im making? Anymore info needed?
one other point. When I checked my XFree4.0.log I noticed the following;
...
(II) [GLX]: __glXInitImports not found. GLX disabled
(II) [GLX]: Add the following line in your XF86Config file:
(II) [GLX]:
(II) [GLX]: Load "glx"
(II) [GLX]:
(II) [GLX]: More hints:
(II) [GLX]: Make sure you are loading libglx.so, not libglx.a
(II) [GLX]: Make sure you are NOT explictly loading libGLcore.
glx will load it.
...
despite the fact I have included the load glx line (and ensured that
libglx.a has been renamed).
Help.

I've used the select() on serial and network stuff and it might work fine
on the keyboard, so give it a try.

The unresolved reference is at linking time - it can't find the actual
definition of pthread_create. You need to tell the linker to include the
pthread library - add '-lpthread' onto the end of the command line.

nfs-utils is not an NFS server -- it's simply the tools that work with
knfsd. Kaz is correct -- you need to enable kernel NFS server support.

Subject: Modifing packets on the wire
Date: Mon, 19 Jun 2000 00:24:48 -0700
Hi, in my network I've got a router that is installed between two subnets.
I want it to take each packet that moves from A to B (or B to A) and modify
it in a specific way. I know that I might have to muck around with kernel
code, so I was wondering if I could do this in user space by using
SOCK_PACKET or something like that. Does anyone have any idea of how I can
accomplish this?
Also, it might be helpful to know that I'm going to develop the program
using redhat 6.2.
Thanks,
Carver
