AW: AW: [suse-programming-e] wxwindows or qt?
by Monaghan, John 26 Jun '03

26 Jun '03

I know I said that my last email was the last comment I would make, but I have to respond to these emails. One reason I rarely post to these lists is because it is so painful. If you disagree or even try and put the other side, you are immediately flamed. Let me put this straight. I use Linux 100% at home, Windows 2000 100% at work I am a Software developer by profession (with a degree) I first started using Linux in 1993 I don't have a problem with QT I DON'T have a problem with wxwindows I use KDE, GNOME, etc..... as my desktop manager .... I find it very difficult when people say I'm right and you are wrong when all of it is subjective - this is called bigotry. Derek Fountain wrote: " > This is my last comment on this subject. Then I won't bother reading or answering." I find this very typical at the moment and the reason why companies such as SCO are having a field day (whether or not they lose their case). They just see arrogance, which is a shame because the majority of us are not. You can comment about QT as much as you like, what I was saying was that I wasn't going to be drawn into a fruitless argument. I did not at any time say QT was bad - I expressed a preference, I use both and neither are bad. Accept the fact that people are going to differ from what you say. To Salman, you missed the point to my email. I don't have the disease that you say - you don't know me at all. I was trying to balance a one sided argument - I will do this for anything because I can't stand bias or bigotry. I don't have to hate Trolltech to love wxwindows, I don't have to hate KDE to love Gnome or vice-versa. My comments reflect the emails that I sent to Julian Smart and the responses I received. Lastly, my time with Linux has not always been smooth - but having done technical support for Windows systems before, I don't want to use Windows. Again this is my choice. The guy who asked the original question needs to make up his own mind, which I think he has.

Several people have this "disease" that software must be free of $$. Anything commercial just doesn't do it for them. While totally neglecting the fact that $$ of software is just a small fraction of what companies pay the developers. In commercial terms, the cost of development software is considered "change" or "drop in a bucket". For those kind of people wxWindows is more attractive. Notice that you could give the same argument for using Linux is the first place. As a matter of fact I STRUGGLED with some font issues for about an hour at work today (after which I gave up and decided to live with the problem). Ever seen a Windows user struggle with fonts? This time alone together with a few other days basically has made Linux itself more expensive than Windows. So back to wxWindows. Even it may be free, the time that you spend find good documentation and learning it will be more than Qt learning curve. I use Linux because I hate M$. If I hated TrollTech, maybe I'd be voting for wxWindows. -- To unsubscribe, email: suse-programming-e-unsubscribe(a)suse.com For additional commands, email: suse-programming-e-help(a)suse.com Archives can be found at: http://lists.suse.com/archive/suse-programming-e

Newbie questions: how to build shared objects
by Serdiouk, Eugene 23 Jun '03

23 Jun '03

Hi, I am just getting my feet wet with C. I have a few object files that I want to convert into a shared library (.so file). Is that as easy as using the right gcc switch, or is it more involved? If the latter, where can I learn how to do it? Thanks, Eugene.

PERL IDE?
by Darrell Cormier 20 Jun '03

20 Jun '03

I am new to PERL. Does anyone know of a PERL IDE for Linux ( I am using SuSE 8.2 Pro). I would like to find something that would allow some form of debugging (i.e. breakpoints, watches,...). Is this possible with PERL. TIA Darrell Cormier

map and pointer
by Verdi March 15 Jun '03

15 Jun '03

Hi, Why is the following code does not work; "delete(s)" causes segmentation fault. But if I change the program to use "map<string*, string> m", "delete(s)" will sucessfully run. int main() { map<string, string> m; string *s = new string("first"); m[*s] = string("first value"); s = new string("second"); m[*s] = string("second value"); map<string, string>::iterator it = m.begin(); for (int i = m.size(); i > 0; i--, it++) { const string* s = &(it->first); delete(s); //this causes segmentation fault. } return 0; } TIA. -- -- Verdi March --

meaning of "typename"
by Verdi March 14 Jun '03

14 Jun '03

Hi, What is the meaning of "typename" in C++? I never realized there's such a keyword until now. For the following function: template<class T> void clearMap(map<string, T> m) { map<string, T>::const_iterator it = m.begin(); /* X */ for (int i = m.size(); i > 0; i--, ++it) { const string* key = &(it->first); m.erase(*key); delete(key); } } g++ will warn that the declaration of iterator it (line marked with /* X */) is deprecated. But using: typename map<string, T>::const_iterator it = ... will remove the warning. TIA. -- -- Verdi March --

Trouble linking cpp object with some library
by Verdi March 13 Jun '03

Hi, Is there any special steps to link a *.cpp to a library created and compiled with C compiler? I have a class that calls a C function in an existing library (libXX.so). This library is written in C. I got the following error while compiling, and I think it happens during linking: =========== cincai@haha:~/tmp/msg++/src> g++ -I../include \ -L/home/cincai/tmp/grimpsim/lib -lsimgrid Host.cpp /tmp/ccfjw59W.o(.text+0x76): In function `Host::Host[not-in-charge](std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, double)': : undefined reference to `MSG_host_create(char const*, char*, double, void*)' ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ /tmp/ccfjw59W.o(.text+0x15a): In function `Host::Host[in-charge](std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, double)': : undefined reference to `MSG_host_create(char const*, char*, double, void*)' ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ collect2: ld returned 1 exit status =========== The content of /home/cincai/tmp/grimpsim/lib is: =========== libsimgrid.a libsimgrid.la libsimgrid.so libsimgrid.so.0 libsimgrid.so.0.0.1 =========== -- -- Verdi March --

Determine the parameters: - Name : prabudb - Connection, Database Type : Adabas - Datasource URL : sdbc:adabas:prabudb - Username : prabudba - Zeichensatz : system 4. Adabas D Statistic : - Control username : prabucon - Password : mypassword. But if I do connection with Username setting (Benutzereinstellung) than I will got this error message after type-in the password (username filled automatically) : " Error in connection with the data source. SQLOD32.DLL " In German : " Fehler bei der Verbindung mit der Datenquelle. SQLOD32.DLL. " If I click detail (Zus�tze) than I have this explanation : " Error code 1000. " In German : " Fehlercode : 1000 " I don't know where the problem. Please tell me what my mistakes. I can do login with control, Query Tools and Domain Tools.
