newbie questions - please help me get started

RE: [suse-programming-e] FSM example
by ntienjem＠netscape.net 27 Mar '04

Quick Introduction to Finite State Machines (FSM) or Finite State Automata (FSA) 1.1 Informal Definition An FSA consists of - a finite set of states, - a set of transitions from state to state; a transition occurs on an input symbol chosen from an alphabet. - an initial state, that is the state in which the FSA starts; it is an element of the set of states. - a set of final (accepting) states; that is a subset of the set of states. - an Alphabet, that is a set of input symbols. Example 1 An FSA which accepts all even numbers. The alphabet is the digits 0,1,2,3,4,5,6,7,8,9. The set of states is {a,b,c}. The initial state is a. The set of final states is {b}. The set of transitions is as follows: = in state a with input 0 or 2 or 4 or 6 or 8 go to state b. = in state a with input 1 or 3 or 5 or 7 or 9 go to state c. = in state c with input 0 or 2 or 4 or 6 or 8 go to state b. = in state c with input 1 or 3 or 5 or 7 or 9 go to state c. = in state b with input 0 or 2 or 4 or 6 or 8 go to state b. = in state b with input 1 or 3 or 5 or 7 or 9 go to state c. 1.2 Formal Definition An FSA is a 5-tuple (S, V, h, s0, F) where - S is the finite set of states, - h is an application which maps SxV to S; that is for each s in S and v in V it holds h(s,v) = s' where s' is in S. - s0 is the initial state; it is an element of the set of states S. - F is the set of final (accepting) states; that is a subset of the set of states S. - V is the Alphabet, that is a set of input symbols. Example 2 Please, reconsider example 1. Since we will be considering the behavior of an FSA on a string of symbols of an alphabet, we have to extend the application h to apply to a state and a string. Let W denote the set of all strings formed using an alphabet. Then, h is an application which maps SxW to S; that is for each s in S and w = w'v in W it holds h(s,w'v) = h(h(s,w'),v), where w' is in W. Example 3 Based on example 2, h(a, 1234) = h( h(a, 123), 4) = ... = h( h( h( h(a, 1), 2), 3), 4) = b. Example 4 a) Consider an FSA which recognizes numbers, e.g. 123, +1234.56E23, -231.45e-05, 432.89. b) Consider an FSA which recognizes all positive integer numbers which are multiple of 3. Definition 1.2 may easily be translated into a C++ program. 1.3 Deterministic FSA An FSA (S, V, h, s0, F) is deterministic (DFSA for short) if for each s in S and each v in V it holds that the number of states resulting from h(s,v) is at most 1; otherwise (S, V, h, s0, F) is nondeterministic (NFSA for short). I hope, I have kept it simple and short. Good Luck!

C# for Linux. Probably worth consideration.
by Steven T. Hatton 16 Mar '04

16 Mar '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I thought about posting this to SLE just for the fun of watching the hysteria unfold, but I would rather not see the list completely melt down. I haven't looked closely at C#, but I have learned a bit of relevant information about it. It is not owned by Microsoft, and it is a formal open standard. I suspect Microsoft bought some very good ideas to put into C++. They also have, at least one or two people there with solid programming experience, and the ability to apply it. The language was designed on the basis of a lot of history, and most likely a lot of research into what works and what doesn't. Microsoft put a lot of effort into C#, and would like to see it catch on. I say the language is worth reviewing as a potential mainstream GNU/Linux development tool. Give if it really does improve the quality and pace of production, then we give MS what the wanted. Buy-in. And we give them all the buy-in they can handle, and then some. If it really does suck, hey, reviewing a language is always an learning opportunity. To ignore it because MS sponsored it, would be like ignoring the technological advancements of another (hostile) country because you don't get along with them. In terms of statesmanship, and history, that is what is typically know as really stupid.

Ant compared to Autotools
by Steven T. Hatton 14 Mar '04

14 Mar '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have to admit, I have never gained a good sense of how to use the gnu Autotools, though I've spent far more time trying than I have with Ant. TrollTech's qmake, OTOH, is very easy to learn. It may simply be the case that Ant hasn't attempted the more complex things Autotools address. I can see some things in Ant which if not addressed soon will lead to the same kinds of obscurity I find in the Autotools. One of the problems I had with Autotools is that the Cygwin install I used had two different versions installed, and I was reading man pages from one version while working with another. /That/ is not a reflection on the difficulty of using Autotools. Nonetheless, when I do look at the documentation, I find myself following references to other documents which are not consistent with the reffering document. KDevelop will generate the files I need for this task, and thus far, I've been able to use the generated results without a problem. However, when I try to understand what all of it means, I am at a loss. Is there a problem brewing with this system? When one script generates another, which generates yet another, it seems there is a potential for the result to become incomprehensible even to the creators of the tools. Does anybody share my concern?

New installation :-)
by Michel Briand 12 Mar '04

12 Mar '04

Dear SuSE users, I've used SuSE since version 6.x, five or six years ago, and now I'm coming back to version 9.0. I've installed Suse 9 on a Serial bases system and installation DVD/CD can't handle such hardware configuration. I've been forced to turn my SATA controler in compatibility mode for Suse to install. Note: on my DVD the media.1/* and media.2/* files are somewhat corrupted and Yast complained about I/O error. I copied those file from CD1. Then I copied entire DVD to my hard disk. I set up a kernel myself (2.6.4-rc2) with my old Linux installation and I modified Grub accordingly. Everything went fine. Except a few warning during init due to Suse init scripts wanting to set up minor console ioctl pertaining to Suse modified kernel. Note about NVIDIA: I own an NVIDIA Quadro 4 XGL. I wanted to use NVIDIA provided drivers. But neither Yast2 nor YOU succeded in installing NVIDIA drivers displayed in patch listing. Although Yast installed correctly the nvidia.o driver for the Suse kernel, it didn't installed the remaining stuff of NVIDIA provided files (libraries and X11 driver). I installed theses files extracting manually the NVIDIA package and executing manually "make install". What was my surprise when I discovered that Suse didn't provide neither MPlayer neither transcode ! I'll have to build those things myself ;-). I needed GLEW library for my developments so I tried krpmbuilder to create one from sources. I went into an ugly issue : dependencies. Although I specified libGL.so.1 in dependencies through krpmbuilder (and I checked the spec file : libGL.so.1 was in Requires string), rpm complained about missing libGL.so.1. Whereas it was installed by XFree86-mesa-devel on my system. Here is what rpm says: error: Failed dependencies: libGL.so.1(LIBGL) is needed by glew-1.2.0-SuSE9.0 I wonder why I was force to say "-SuSE9.0" in krpmbuilder. And I wonder why rpm searches for (LIBGL) tag ??? Anyone master "build" and rpm to help me create a robust spec file for GLEW ? And it would be nice to discuss with GLEW team about tarball naming convention, and installation directories conventions... I attached my somewhat "alpha" spec file. Regards, M.B.

newbie qmake issue - multi threading package?
by Allen Seelye 12 Mar '04

12 Mar '04

I really have two issues here but I think they both are symptoms of the same problem so I've stuck them both in the same message here. I'm trying to compile the famous 'hello world' program. The first issue I'm running into is tellng qmake the location of qapplication.h or any include files at all. I have QTDIR set, as well as the appropriate entry in ld.so.conf but it still cannot find those files unless I include the complete path in the #include entry. Then I run into the second issue. When compiling I get this error: .../bin/ld: cannot find -lqt-mt collect2: ld returned 1 exit status make: *** [hello_world] Error 1 My googling has led me to believe that I need to install the qt-mt package (or something along those lines) but I have been unable to find any such package. I'm using suse 9.0 and qt is installed from the suse 9.0 packages, NOT from sources. Any hint is appreciated. -- Allen Seelye Alleninmt(a)yahoo.com A Linux user since 1999. --------------- "It's a trick, get an axe."

wxWindows looks terrible

I'm just experimenting with wxPython coding with wxWindows on SuSE 9.0. However, my application looks awful. And it's not my code - the demo apps look awful too. The font is ugly (every font you pick looks just the same) and the general look and feel is terrible. Since wxWindows on Linux is based on gtk, I assume this is because my gtk installation isn't properly themed or set up. Does anyone know how to fix this? My desktop is KDE so I do not have Gnome installed, but I run gtk-based apps like Gimp and Eclipse and they look fine. Best wishes - Ken

WAS "A good book on C programming", now an APPOLOGY

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear Everyone, I was had this pointed out to me, by Simon Perreault <nomis80(a)nomis80.org> (with my reply): "On Saturday 27 Dec 2003 8:49 pm, you wrote: > 1) Please do not cross-post. (This means sending the same message to many > lists.) OK, guilty, but I wanted a varied response, as different people subscribe to different lists. > > 2) Please stay on topic. This has nothing to do with Fedora. Fedora is GNU/Linux, there are C programmers, like you that use Fedora, and it is a general discussion list. What's the problem? I'm not asking for money for for you to join some crazy scheme. This kind of attitude annoys me about GNU/Linux, I am not wasting anyones time, so I don't see what the problem is." And his last reply: "On December 27, 2003 16:11, you wrote: > This kind of attitude annoys me about GNU/Linux, I am not wasting anyones > time, so I don't see what the problem is. Yes, you are wasting time (and bandwidth, as there are some people on very slow connections) when you are not on topic. This list is not even about GNU/Linux, it is about Fedora. General Linux questions do not belong here. This is Fedora-related stuff only. There are tons of Linux and C mailing lists. This is a quick lesson (that everyone must learn, I did too) on netiquette. You should Google a bit on that topic, particularly on stuff related to mailing lists." I am sorry if I have wasted everyones time and bandwidth, but I have spent the last 3 days searching for up to date links and book reviews, some things you never find, like the website: http://www.accu.org/bookreviews/public/ recommended by another user. I admit, I have cross posted, as I not only use Fedora, but Debian, SUSE and Gentoo. These are all different distro's with different user bases. I wanted to get a good feel of what are good texts from all the C programmers out their. I didn't get a response like above from anyone else. Even Alan Cox replied to me. What I don't understand is, and I quote, "This list is not even about GNU/Linux, it is about Fedora." What is Fedora then? Again, sorry to waste everyones time, but you have all helped me out. - -- Regards http://www.magicfx.co.uk http://www.suretecsystems.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) iD8DBQE/7f0YgNqd7Kng8UoRAimuAKCikZFb2yBGtrHss8AWHmb7pPwQMwCg4OAT hiT3sr0rPLJBLtQl/uiqQOU= =mTvq -----END PGP SIGNATURE-----

KDevelop. Opinions? Experience?
by Steven T. Hatton 04 Mar '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Has anybody worked with KDevelop? IMO this is one of the most important projects in the Linux Community, and especially in the KDE environment. If you've ever worked with JBuilder, you will know what IDE features can add to the development environment. There is NOTHING comperable for C++ that I know of on Linux. http://www.kdevelop.org/ I like JBuilder, and I like doing business with Borland, so I feel kind of bad holding them up as competition, but JBuilder is mark to meet, IMO.

4 GB address space ?
by William A. Mahaffey III 01 Mar '04

01 Mar '04

I am new to the list. I have various codes currently native on SGI hardware that I am interested in porting to Linux, specifically SuSE. I was attracted to SuSE by the reputed ability to address a larger part of the 4 GB 32-bit address space (larger than the usual 2-GB). To that end, I have tried to port a small benchmarking program to SuSE 8.2, on an Intel P4 box, 2.4 GHz, Biostar P4TSV mbd, w/ 2 GB of RAM (for now) & 1 GB of swap space. This box is a compute node on my network & is accessed by ssh; it has no monitor, kbd, or mouse, & runs in runlevel 3 by default. The benchmarking program executes various floating point array operations on successively longer arrays (allocated w/ malloc) until the malloc calls fail or until an upper size limit is reached. I was running the program last night & observed that I could successfully allocate sloghtly over 2 GB of memory (~2350 MB), but when I began operations, the process (as well as the parent shell & login shell, apparently) hung. I killed the login processes from the machine I was logged in from & was able to log back in w/o rebooting. Several questions: 1. I tried to set up a swap partition of > 1 GB & the installer wouldn't let me, how do I get around that ? 2. Is there a problem w/ having more RAM than swap ? (I have 2 GB RAM, 1 GB swap at the moment) 3. I had problems w/ the installer w/ 2 GB of RAM installed, when I removed 1 GB to test why I was having problems, everything went well, total install in about 20 minutes on newly formatted system disc. Is there a known problem w/ the installer w/ more than 1 GB of RAM installed ?

C++:Can one constructor call another from the same object?
by Steven T. Hatton 01 Mar '04

01 Mar '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 In Java it's quite common to call one constructor from another one in the same objects. Can that be done in C++? Is the same kind of situation handled in C++ with default values for arguments to the constructor rather than having two different constructors?
