Has anyone tried using CLAPACK in RH Linux (kernel 2.2.5)? How were you
able to write the makefile? I have already explicitly defined some
include files but the compiler still can not seem to see them...
Thanks in advance,

you can do ioctl on a socket as well. after all, it's just another file

not entirely true. the cryptography field has developed authentication
protocols that could indeed limit the number of copies of a given software
package active at any given time, and also safely check for the existence
of a valid, non-easily-fakable, unique key. of course, you then go from
the machine being a SPOF for the software running on that machine, to the
license server being a SPOF for that software package running on *all* your
machines. ask our unix admins some time how much they like the FlexLM
license manage, and you'll get an idea =)

You have to have LILO. A bit more precisely, you have to have a boot
loader -- something sitting in the boot sector that tells the machine
how to load the OS. The normal boot loader for Linux is LILO.

Another way to have an important part of the application not on
the system would be to have it on an hardware parallel port plug
key, one of the intelligent one which can crypt and decrypt.
I think, IHMO, that storing all constant data (if you have big arrays)
or even a part of the code on the PC, as encrypted, and for your program
to run you have to send all encrypted information to the key (for
decryption), is a quite good protection: the protection is a physical
device you have to watch for. Someone with a good knowledge could
debug (with gdb) your software to get back the decrypted data,
so you should not decrypt all at once in your application, but anyway
if he has access to the key he can also steal it, that is simpler for
him. It is then better to _not_ have the PC on a network.
You could also have the complete application running on a parport
key if they were enought powerfull...
The problem is that (I think) nobody has made such a parport key,
with the basic libraries (you need the source to check them!),
for Linux or other PC Unix system.
Just my 0.002,
Etienne.

Sales is not the problem, but the "intellectual property" inside the
application.

There's nothing misleading about it.
Kaffe can do java and compile java.
IBM's JDK is very good and faster than Blackdown's JDK.

You're really asking a lot here: you want to restrict the application
to certain machines (but not your own), you don't want to use a
dongle, you don't want to trust your users.
The PC architecture does not have any kind of host ID built in. Other
platforms (such as Suns) do, but even in Solaris it's possible to hack
the kernel to make it return something else. On Linux it would be
even easier, assuming that a hardware host ID existed: since the
entire kernel source is available, simply hack it (this isn't going to
be running on your machines, since you specifically don't want to use
your own resources).

See the MkLinux project. It is a co-located Mach kernel and linux
server running on PowerPC systems (maybe others?). It is reputedly
a tad slower than the monolithic LinuxPPC. However, this is perhaps
a bit biased as all the application programs are designed and
compiled for a monlithic model.
There are many other micro and nano kernels around, such as MacOS X (via
NeXT) / Darwin, Fiasco/L4, GNU Debian/Hurd etc.

You could write all software in assembler too, but I doubt you could
feasably do "anything". The nice feature of micro kernels is the
provision for greater kernel modularity and reliability. So to say the
monolithic linux kernel is 'better' than a microkernel (and there are
micro kernels other than Mach) is just propaganda.

This is not true. There are many things which smarter and better
designed OS can do which the standard unix clone struggles with.
Look a bit beyond hello world.

Hello,
This may probably sound stupid to most of you but
I'm just a Linux newbie.
So far, I've been programming console apps in Linux using
gcc and cc.
I'm now interested to know how to program in graphics mode.
I don't know how to explain this but I used to program
in DOS using Borland Turbo C, which has a (documented) graphics
library. I'm sure some of you know what I'm talking about
and have used it.
I'm looking for an equivalent in gcc linux. (It doesn't have
graphics.h does it?) I don't want to resort to assembly language
since I know linux has a (documented) graphics library somehow.
Please help me, I'd really appreciate it.
Please email me. Thank you!
