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?

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?

-----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.

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?

-----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++?

Matthias Ettrich in praise of MS Windows IDE's
by Steven T. Hatton 27 Feb '04

27 Feb '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 "Favorite editor? Hard to say. I'm mostly using XEmacs and it's quite ok. But it's not my favorite. It lacks very useful editing features known from MS-Windows IDE's, like showing a function's arguments when typing a call in the code. This requries profound C++ parsing and understanding in real-time, nothing you can do fast enough in lisp, unfortunately. So eventually, we have to replace Emacs with a K-Tool, I guess." This is now a couple years old, but things really haven't changed regarding C++ that much. It's getting there in KDevelop, but right now it's got the best of them challenged. Part of the reason the functionality isn't there is because too many people don't share Matthias's opinion. But what's Matthias Ettrich know about programming anyway?

ccache: often results in a 5 to 10 times speedup in common compilations?
by Steven T. Hatton 25 Feb '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I found this sitting on my harddrive. Has anybody used it?: /usr/share/doc/packages/ccache/ http://ccache.samba.org/ "ccache is a compiler cache.

This often results in a 5 to 10 times speedup in common compilations. The idea came from Erik Thiele wrote the original compilercache program as a bourne shell script. ccache is a re-implementation of Erik's idea in C with more features and better performance."

Qt OpenGL qt/qt-mt linking problems
by Martijn Houtman 23 Feb '04

23 Feb '04

Hello, When compiling the examples in the Qt examples dir (opengl gears example) and bumped into some errors. Firstly, I get the following linking errors: gear.o(.gnu.linkonce.d._ZTV10GearWidget+0xc): undefined reference to `QGLWidget::className() const' gear.o(.gnu.linkonce.d._ZTV10GearWidget+0x10): undefined reference to `QGLWidget::qt_cast(char const*)' gear.o(.gnu.linkonce.d._ZTV10GearWidget+0x14): undefined reference to `QGLWidget::qt_invoke(int, QUObject*)' Now, when I replace the -lqt in the Makefile by -lqt-mt, they link just fine. Is this a bug in the Makefile's from Trolltech, or some weird behaviour in SuSE's qt libs? These are the (unsupported?) qt3-3.3.0-47 libs from supplementary/KDE/update_for_9.0. Ok, replacing the qt with qt-mt works fine, but then the output is scrambled (take a look at http://www.suse-irc.org/temp/snapshot1.png) This did not occur with the regular qt libs SuSE 9.0 provides, but then I cannot run KDE 3.2 :) Thanks in advance, -- tinus.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 This message turned into a bigger listing than I originally intended. I guess I should put to gether a web page of C++ resources I like. This may have been posted before, but it seems worth calling people's attention to again. List membership changes over time, and sometimes things like this are forgotten. I haven't read all the tutorial, but it is the kind of thing that I should have read at the beginning of my C++ ordeal...uh I mean to say learning effort. http://www.cplusplus.com/doc/tutorial/index.html I know I posted this title before. It's along the same lines, and is what I actually used as a 'jump start'. _Essentials of C++_ http://www.booksmatter.com/b0878917489.htm Another short and sweet treatment of some aspects of C++ is: C++ Notes: Table of Contents http://www.fredosaurus.com/notes-cpp/index.html Also worth mentioning is: C++ GUI Programming with Qt 3 by Jasmin Blanchette and Mark Summerfield "This is the first official Qt book, written by two veteran Trolls. The book is now available in US bookstores and from online booksellers." http://www.trolltech.com/ It's taken me about 100 pages to adjust to the presentation style. But if you just understand that they treat code listings as paragraphs, and they always present the code, and then describe it, usually with very little prior introduction, the text will probably read smoothly for you. I guess it's a sign that I am learning the C++ language when I look at a page full of code and feel relieved that I will almost certainly get through it fastart than a page of prose.

"<table></table>" and "<frameset><frame></frame></frameset>" in perl/tk
by Prabu Subroto 03 Feb '04

03 Feb '04

Dear my friends... Anybody would be so kind telling me what is similar in perl/tk to arrange the location of a form written in perl/tk? I want a nice look for my perl/tk application. Somewhat like this below: 1. Name : <place to type-in> 2. Address : <place to type-in> 3. Telephone : <place to type-in> I have made the main menu of my application with "Menubutton". And I want if the user click on the menu that what the user see is only the aimed application displayed on the determined area (under the main menu) but the menu has no change in position and form. Somewhat like on HTML: === <frameset><frame name=mainmenu src=mainmenu.html></frame><frame name=display></frame></frameset> ===  <table> <ol> <tr><td colspan=2>Main menu :</td></tr> <tr><td>1.</td><td><a href="biodata.html" target="display">biodata</a></td></tr> </table> === So the mainmenu will not have any change only the content of the display frame will have change as the user work with this application main menu. Thank you very much in advance. === #my current perl/tk code: #!/usr/bin/perl -w use Tk; my $mw = MainWindow->new; $mw->title("i\@m NA - Linux Server Administrating Tool"); $frmm = $mw -> Frame(-borderwidth => 2, -relief => 'ridge')->pack(-side => 'top', -anchor => 'n', -expand => 1, -fill => 'x'); $mobject = $frmm -> Menubutton(-text => "Administrated Object", -menuitems => [['command' => "Samba", -command => \&menusamba], ['command' => "Squid", -command => \&menusquid]])->pack(-side => 'left', -anchor => 'nw', -expand =>0); $msetting = $frmm -> Menubutton(-text => "Setting")->pack(-side => 'left', -anchor => 'nw', -expand => 0, -after => $mobject); $mfile = $frmm -> Menubutton(-text => "File", -tearoff => 0, -menuitems => [["command" => "New Document", -command => \&new_document], "-" ])->pack(-side => 'left', -anchor => 'nw', -expand => 0, -after => $msetting); $doc_num = 1; $doc_list_limit = 9; $mw -> Button(-text => "New Document", -command => \&new_document)->pack(-side => 'bottom', -anchor => 'e'); $entry = $mw->Entry(-width => 80)->pack(-expand => 1, -fill => 'both'); $mexit = $frmm -> Button(-text => "Exit", -command => \&keluar, -borderwidth => 0)->pack(-side => 'left', -anchor => 'nw', -expand => 0, -after => $mfile); $mhelp = $frmm -> Menubutton(-text => "Help")->pack(-side => 'right', -anchor => 'ne', -expand => 0); $judul = $mw->Label(-text => "Network Administrator Main Menu", -anchor => 'center')->place(-y => 30, -x => 0); MainLoop; sub keluar{ exit(); } sub menusamba{ $judul = $mw->Label(-text => ""); } sub new_document{ my $name = "Document $doc_num"; $doc_num++; push (@current,$name); $filem->command(-label => "$name", -command => [ \&select_document, $name ]); &select_document($name); if ($#current > $doc_list_limit){ $filem->menu->delete(2); shift(@current); } } sub select_document { my ($selected) = @_; $entry->delete(0,'end'); $entry->insert('end',"SELECTED DOCUMENT: $selected"); } __________________________________ Do you Yahoo!?

Porting from Solaris
by expatriate 02 Feb '04

02 Feb '04

Hello All I started a thread some time ago called "GPL Issues" I got some responses which of course generated a bunch more questions. I'm talking to the powers-that-be in my company (which is quite huge, global 500) about moving one of our products' OS from Solaris to Linux. In other words, we make a product that has an embedded computer running Solaris and now we are considering making the same product but running Linux instead. The product is sold to companies who have absolutely no interest in the source code (this is true). Does anyone on this list have experience (that they're willing to share) on their legal issues of porting from Solaris to Linux? I've already been to gnu.org and read all of their GPL and LGPL documentation. Furthermore, my email questions have gone unanswered (probably due to lack of staffing). TIA & Cheers
