Look in debian/rules (the main Debian build script) in the php4 source
package and you'll see that it passes *loads* of arguments to
./configure, so it would make sense that missing out things like
--with-apxs would break it.
If you just want to build a package quickly, with the standard Debian
options plus a few of your own, editing debian/rules and typing
'debian/rules build' from the top-level source directory is the fastest
way to do it, assuming you've got all the build dependencies installed.
This won't give you a proper package, and won't even install the package
into a temporary directory; it's the moral equivalent of './configure;
make' without the 'make install'. You can copy the files yourself to
wherever they're supposed to go.
(Stop reading here if you only want a quick fix. :))
On the other hand, you might want to do it the full-blown proper way and
get yourself a Debian package with your own customizations. The way to
rebuild a Debian package with your own options and have it work at least
as well with your system as the original is as follows.
* Make sure you have all the build-essential packages installed (see
/usr/share/doc/build-essential/list in the package actually called
'build-essential', or
http://www.debian.org/doc/packaging-manuals/build-essential).
* Make sure you have all the packages listed in the Build-Depends:
line in debian/control in the relevant source package.
* Install 'fakeroot' as well: it means you don't have to build as
root.
* Edit debian/rules and customize it whatever way you want.
* Edit debian/changelog and add a new entry at the top with the same
syntax as the earlier ones. Use your own name, today's date, and a
newer version number - adding .0 to the end, say, will make it
unlikely to clash with any future official packages, although you'll
have to rebuild each time new fixes come out from Debian or
upstream.
* Type 'dpkg-buildpackage -rfakeroot' in the top-level source
directory.
* Wait, or debug if you need to. Eventually it should spit out a .deb
in the parent directory; check it with 'dpkg-deb -I foo.deb' and
'dpkg-deb -c foo.deb', then try installing it.

Subject: 2 x RTL 8139 Cards = doesn't work
Date: Tue, 26 Sep 2000 18:20:17 +0200
Hi,
I'm trying to get a PC with 2 100/10 RTL 8139 based cards to recognised
and configure both correctly.
I currently have the kernel compiled to include support for the '8139,
it detects both eth0 and eth1 and reports their MAC addresses at
startup.
My ifcfg-eth0 and 'eth1 scripts are excecuted and if config shows both
cards to work. If I try to ping a known host on the subnet of eth0 I
get a situation where the network requests queue up and aren't sent
*ever*.
I reboot (removing) the 2nd card, all works fine. (eth1's
initialisation is just delated).
Does anyone have a similar experience or perhaps know why I can't get
both working simultaneuosly?
Regards
Paul

Um, no, I never said anything about a symlink. Your startup could
do something like:
mv /etc/.backup/syslog.real /etc/syslog.conf
syslogd
mv /etc/.backup/syslog.fake /etc/syslog.conf
Quite safe and secure, especially if you do it by hand instead of
automating it in a script. And no links to give it away.

Somewhere in the 2.3.99 to 2.4.0-test series, some nasty memory
management bugs were introduced, and it's not clear that they've all
been worked out yet. They don't bite everyone, so some people are happy
enough with 2.4 kernels - I'm using 2.4.0-test2 without too much
trouble, though earlier kernels had serious performance problems for me.
But, for the people they do bite, I can see why there might be a good
reason to stay back at 2.3.51 for the time being.
Of course, if you're going to run development kernels, you might as well
at least try the latest ones.

Well, you could try changing the NGROUPS #define in
linux/include/asm-i386/param.h [1] [2] and the NGROUPS_MAX #define in
linux/include/linux/limits.h to the figure you want, and recompiling
your kernel.
[1] ... where linux/ is wherever you've got your kernel source tree.
[2] asm-i386 might be asm-sparc, asm-alpha, or whatever your processor
architecture is.
However, some userspace tools - like your C library, for instance -
might well be compiled against these header files too, and you'll have
to rebuild all of those. Trust me, you really do not want to have to
rebuild your C library if you can possibly help it.
Instead, do it a different way, and forget about the limit on
supplementary groups. Have a look at 'sudo', which can almost certainly
do what you want in a much cleaner and easier way.

Subject: NEED HELP w/ Linux install and X Server setup on Laptop...
Date: Tue, 26 Sep 2000 11:28:03 -0500
I have an HP Pavilion N3250 Notebook.
AMD K6/2 475MHz
6.0GB Harddrive
12.1 Inch SVGA TFT Display
Trident Cyberblade I7 AGP 3D Graphics.
I am installing Mandrake 7.1 using lnx4win because I don't want to
remove Windows. I was able to install it and get it running but I wasn't
able to get the X Server running. I found a reference on how an N3270
(which has the same video chipset, just a larger display) was setup at:
http://vorpal.nebrwesleyan.edu/~mcclung/hp3270.html.
I read that I need to use the Frame Buffer as in the way the N3270 uses
it. I tried using the svga X Server but couldn't come up with any
combinations of video/monitor that worked so I then tried the Frame
Buffer. But, I didn't have a XF86_FBDev in /usr/X11R6/bin. I only had
XF86_SVGA and XF86_VGA16. So I download an XF68_FBDev (yes, it says XF68
not XF86, why?? I don't know, does anyone know why?) and tried that. But
I got this error:
unable to open device /dev/fb0 (no such device)
I also read that XF86_FBDev comes with xfree86 3.3.6, which comes in
Mandrake 7.1 (correct me if I'm wrong). So, does this get installed
normally or do I have to specify it to get installed when I run lnx4win
(drake)?
So, to sum it up, here's my questions/needs:
What to I need to have installed when I install Linux on a laptop
(specifically XF86_FBDev)?
How do I setup the X Server? Do I use the Frame Buffer? How do I
install the Frame Buffer?
What do I need in my XF86Config file? (There's an XF86Config file in
the above web page for use with FBDev)
Any help would be greatly appreciated. Thanx,
Brandon

Yup. Going through the file system slows things down.
Also with a swap partition not only do you bypass the
file system but the pages are contiguous. It doesn't
get fragmented the way a swap file can.
With cheap multigig drives unless you're really on a tight
budget it's probably a better use of your time just to put
in a big drive.

The Network Card's bios mu�t support this, esp. the nic *has* a bios/rom.
After initialisation of the system the master bios seeks a boot device,
this may over take by a BootProm on the NIC.
After this sage the boot process may start, the NIC rom broadcasts
into the Ethernet an searches vor a aktive bootp server,
this assigns a IP Address to the Boot-Client,
and delivers over tftp a "Boot" image = the Kernel file.
Further initialisation is the part of the "initial Ramdisc" contents
and ther existing scripts to boot up the diskless client.
Search the ftp.kernel.org for "boot/etherboot" and simular environments
do setup such beast.

The BIOS is involved with the switching, but XFree has to be configured
to supply an appropriate signal that the external monitor can
understand. Since the panel display has a sync rates that are likely to
be different from the external CRT, I need some way to switch these
things when I switch to the second display.

I now am the proud owner of a triple boot Nt4/win2k/linux system.
The trick is to have 3 hard drives. It works very well. I have linux
on
hda, nt4 on hdb and win2k on sda. Lilo boots the computer, win2k and
nt4 don't really know linux is there because lilo remaps the drives in
bios. This makes setup of msft o/s very easy because you can set up the
drive as the boot drive, setup the msftos and then reconfigure. To boot
you reconfigure using lilo.

I think you must start linux in single mode. Now you must erase the
password field in the file /etc/shadow
the password is crypted and is between the first and the second ':' .
Now restart linux and reinsert the password, linux ask you the confirm and
you reinsert the password.
