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.

The cplusplus.com tutorial (on-line) and other resources.

-----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.

I'm new to C in linux. Btw, I'm having a problem with function such as pow(x), sqrt(x), etc. For example, i wrote a program like this : #include<stdio.h> #include<math.h> main() { float a, b; b = pow(a, 3); printf("Result is : %f\n", b); } when i try to compile it using gcc, it keeps telling me an error like this ------> undefined 'pow' in main ....bla bla bla anyone can help?

by Ryan Walsh 18 Feb '04

18 Feb '04

I'm just getting back into programming, and this is my first introduction to LINUX. I was wondering if anyone had a basic C program on how to read input from the keyboard one character at a time (without having to press enter)... Thanks!!

building kdesdk3 nightshot
by Ivan Sergio Borgonovo 17 Feb '04

17 Feb '04

I'm having blocking problems with Umbrello so I decided to compile latest release. I downloaded last src from SUSE, changed the version number in the spec, substituted the original SUSE tarball with the newest. This is what I got: main.cpp: In member function `virtual int KBabelApp::newInstance()': main.cpp:103: error: `restoringSession' undeclared (first use this function) It seems to be some error due to missing source, what should I install to successfully build it?

question
by Andreas Roditakis 12 Feb '04

12 Feb '04

Hello folks..! I am looking forward to buy a IEEE 1394 PCI Adapter, in order to program a video/image capture program. The questions are: 1.Is it the correct decision to buy IEEE 1394? Maybe USB 2.0 is also alright for image capture with a digital camera. I wonder if digital cameras support Firewire or only usb 2.0. 2. Searching in the hardware database from SuSE i find not much info on IEEE Cards...Does anyone have experience with compatibility? My specs: Intel PC with P4 1.7 Suse 8.2 prof.

XVisualInfo problem
by Indra Geys 10 Feb '04

10 Feb '04

Hello, I am having problems with X window rendering and GLXFBConfig. If I try the choose a GLXFBConfig with attribute GLX_ALPHA_SIZE,8, then I get an error. I checked this and it seems that I don't have an XVisualInfo which has a alpha color buffer different from 0, although xdpyinfo gives that I have 12 visuals. I have a quadro FX 500 graphical board, and I tried already to install the latest four nvidia drivers for it. Nothing helps. I am just changed from redhat 9.0 with nvidia driver 1.0-4363, and there I had no problems. Does someone know how I can get the appropriate visual, and can solve the problem? Indra Geys
