My X have no voice. No pritty, piing, zoom, badaboum, or anything else.
How can I set it up?
Have anything for soundcards like gmpconfig for mouse under lovely Linux?
squake have no sound too. :-(
Any help can save the word :-)
ps. have any program like soundforge (under MsW9x) for linux or wine can
cooperate with soundforge?? 'Couse my young brother (age 25 :-) like to
change win to linux absolutly, if he can solve this problem.

I am currently porting some kernel code from x86 to alpha. This code
checks to see if the kernel is currently executing a system call. In order
to do this, it checks orig_eax>=0, eax == one of three values. How would
one do this under alpha? Any help would be appreciated. Thanks in
advance.
Warmest regards,

My guess is
1) You do not have the sound module loaded
cat /dev/sndstat
should show what devices are configured and if none
then check to see if you have sound modules which
need loading
ls /lib/modules/2.0.37/misc (use your version number)
will show all the sound modules (and others)
2) You do not have sound support, or your support is not
set to your soundcard. This would be very strange for a
distribution; almost all include sound support, but perhaps
it is loading the wrong one, or using IRQ 7 instead of IRQ 5
If you are brave enough to fix it yourself (go ahead! it's fun!) Look
in the /docs/HOWTO directory of your Linux CD and find the
Sound-HOWTO, then follow that advice carefully.

You can but there are issues with doing that (what process owns the
file descriptor?). Try this instead: publish a /proc file. Keep a
ring buffer and feed the /proc file with it. Then just make a
userspace daemon select() on the /proc file and write your log. I
haven't checked but I think printk/klogd does something like this.

Subject: glibc-2.1.1 setup
I'm having trouble setting up glibc-2.1.1. "make install" tries to run
perl, which needs libm.so.5 (I'm using perl version 5.005_03)...but if
"make install" libm.so.5 in my path, it quits with:
The script has found some problems with your installation!
Please read the FAQ and the README file and check the following:
- Did you change the gcc specs file (neccessary after upgrading from
Linux libc5)?
- Are there any symbolic links of the form libXXX.so to old libraries?
Links like libm.so -> libm.so.5 (where libm.so.5 is an old library) are
wrong, libm.so should point to the newly installed glibc file - and
there should be only one such link (check e.g. /lib and /usr/lib)
You should restart this script from your build directory after you've
fixed all problems!
Btw. the script doesn't work if you're installing GNU libc not as your
primary library!
Can someone please help me out with this?
Thanks,

Two ways:
If the X server is local to a machine and you have a home directory
there:
1. Put the font file in a directory under your home directory.
2. Add fonts.scale entries as appropriate.
3. Run mkfontdir to create the fonts.dir file.
4. Use xset [+fp|fp+] to add the directory to the X server's
font path.
5. Use xset fp rehash to make sure the X server's list of fonts
is up to date.
If you do not have a home directory on the machine the X server is running
on, but do have access to a machine you can run a font server on:
1. Do steps 1-3 above on the machine you have access to.
2. Create a config file for the font server that names the directory
the font is in.
3. Start the font server.
4. Use xset [+fp|fp+] to add the font server to the font path.
5. Use xset fp rehash to update the font list.

The script is just a security check. Please read the glibc2 FAQ and
the glibc2 HowTo and check the above mentioned points.
Your systems seems to be at least partly broken. There's no more help
neccessary than you've got already with the above messages and the
documentation.

Subject: Serial device (c language)
Date: Tue, 20 Jul 1999 11:20:05 +0200
I'm trying to use a serial device on a pc.
My problem is I want to define a timeout and use it when I have to read
somehting on the serial device.
I have try to use the tcsetattr() function from termios.h library with
the VTIME and VMIN parameters of c_cc attribute, but ot seems not work.
In fact, I have test these three cases :
- MIN > 0 and TIME = 0 : it works, ie when I use the read function, and
there is nothing to read, the function never return
- MIN = 0 and TIME > 0 (TIME = 500) : it doesn't work, ie I use the
read function, there is nothing to read, the function return immediatly
(there is no timeout )
- MIN > 0 and TIME > 0 (TIME = 500) : it doesn't work, ie I use the
read function, there is nothing to read, the function never return.
What I want to do is, when there is nothing te read, the function read
wait until timeout is finish, and then return a wrong value.
If somebody can help quickly.
Thanks

I guess you don't have mkfs.dos (mkdosfs-0.4-4.i386.rpm) installed. Use
fdformat to format a floppy. Use mkfs.dos to put a dos filesystem on
it. Then mount the disk and read/write to your hearts content.

Well, you have to compile the whole kernel at some point. Once you end
up with object files (.o) for each source file that goes into your
particular configuration of kernel, however, you can simply edit this
source file and re-run "make bzImage" (or whatever) from the source base
directory. Don't re-run "make dep; make clean", or the whole kernel will
get rebuilt again. "make clean" deletes all object files.
Note - "make bzImage" and friends do recomplie a couple of other files
every time. Don't worry about this.

The most beatiful approach, in my opinion, is to use what the standard
library uses, which is predicates. The approach is just slightly
different from your last one:
template <class T> struct less : public binary_function<T, T, bool> {
bool operator() (const T& x, const T& y) const {return x<y; }
};
template <class T>
inline const T& min(T const& a, T const& b) {
less comp;
return comp(a, b) ? a : b;
}
Now we specialize less for our class Strange
template<> struct less : public binary_function<Strange, Strange, bool>
{
bool operator() (const Strange& x, const Strange& y) const {return
x.strangeLessThan( y ); }
};
Which would look like:
main
{
Strange x;
Strange y;
Strange m = min(x,y);
int a, b;
int c = min(a,b)
...
}
The application programmer will only have to worry about specializing
less for the Strange class, nothing else. The main code is simple,
elegant, no extra run-time costs!
