glade prob
by oguz eren 19 Jan '04

19 Jan '04

Hi, I'm trying to learn glade. autogen.sh failed on my first try; giving the error below: ./configure: line 4068: syntax error near unexpected token `PACKAGE,' ./configure: line 4068: `PKG_CHECK_MODULES(PACKAGE, $pkg_modules)' Then i learned that i had to install pkgconfig; i did so; but this time autogen gave the following error: checking for gtk+-2.0 >= 2.0.0... Package gtk+-2.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `gtk+-2.0.pc' to the PKG_CONFIG_PATH environment variable No package 'gtk+-2.0' found configure: error: Library requirements (gtk+-2.0 >= 2.0.0) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them. How do i have to set PKG_CONFIG_PATH environment variable? Thanks in advance.

c++ warning ??
by ged.suse＠ntlworld.com 30 Nov '03

30 Nov '03

Hi all, I'm currently rewriting many of the standard functions in C++. No i'm not wierd, i'm in the process of learning and figured this would be a good exercise. Anyway, my strlen() function is bringing up a warning. Although I understand what the warning mean, I don't understand why it is a warning. Can someone please quickly point out the technicalities. The main point I sometimes trip up with is pointers and references (as I suspect most people learning C++ encounter) int *MyStrlen(const char *source) { int i = 0; while (*source) { *source++; i++; } return &i; } Thanks ----------------------------------------- Email provided by http://www.ntlhome.com/

Bug in gcc?
by praisetazio 29 Nov '03

I got this line: ... buf->lockstart = PTHREAD_MUTEX_INITIALIZER; ... Gcc returns me an error: /home/praise/progetti/beyond/src/buffer.c:33: error: parse error before '{' token A substitution with the following line pthread_mutex_init(&buf->lockend, NULL); work properly. When does the '{' come out? Am I supposed to use PTHREAD_MUTEX_INITIALIZER only at initialization? Praise

Dear Suse Linux Programming members: Since I could not find a more appropriate Suse email discussion group I am writing here. I wish to instal Suse Linux (Persoanal or Professional), and I have a major problem: I want to access the Internet using a Cable Modem (Motorola SurfBoard SB4100), however I cannot find it in the list of Suse Linux supported hardware. I assuem there is a (Suse) Linux driver for this equipment. Please, advise: 1) Where may I find this driver, or/and 2) How can I use suse Linux with my Cable Modem ?

Installing a Python module
by Graham Smith 10 Nov '03

10 Nov '03

I'm just starting to learn python and am trying to install a module named pySerial. http://pyserial.sourceforge.net/ Installation details provided from the above site:- ------------------------------------------------------------- Extract files from the archive, open a shell/console in that directory and let Distutils do the rest: python setup.py install The files get installed in the "Lib/site-packages" directory. -------------------------------------------------------------- When I run the above command I get the following:- merlin:/home/graham/tmp/pyserial-2.0b2 # python setup.py install error in setup script: invalid distribution option 'classifiers' merlin:/home/graham/tmp/pyserial-2.0b2 # Just wondering what I'm doing wrong or is the setup script at fault, if so how can I manually install the above module? -- Regards, Graham Smith ---------------------------------------------------------

Strange characters from cout
by Richard Bos 10 Nov '03

10 Nov '03

Hello, I compiled a c++ rpm install program which gives some strange/unexpected output while using cout. I have consulted several sources, but untill now no success. The output I get is the following: After unpacking 11.2MB of additional disk space will be used. \?x×Bèÿ¿ÀT?@àçÿ¿ØÿX@èçÿ¿mBM@ \?x×Bèÿ¿ÀT?@àçÿ¿ØÿX@èçÿ¿mBM@ Executing RPM (-Uvh)... Preparing... ########################################### [100%] 1:python-devel ########################################### [100%] or Do you want to continue? [Y/n] \?x×Bèÿ¿ÀT?@àçÿ¿ØÿX@èçÿ¿mBM@ \?x×Bèÿ¿ÀT?@àçÿ¿ØÿX@èçÿ¿mBM@ \?x×Bèÿ¿ÀT?@àçÿ¿ØÿX@èçÿ¿mBM@ \?x×Bèÿ¿ÀT?@àçÿ¿ØÿX@èçÿ¿mBM@ \?x×Bèÿ¿ÀT?@àçÿ¿ØÿX@èçÿ¿mBM@ \?x×Bèÿ¿ÀT?@àçÿ¿ØÿX@èçÿ¿mBM@ \?x×Bèÿ¿ÀT?@àçÿ¿ØÿX@èçÿ¿mBM@ Executing RPM (-Uvh)... ?èÿ¿Za0 The involved code looks as follows: { ...... const char *operation; .... case Item::RPMUpgrade: if (Interactive) operation = "-Uvh"; else operation = "-Uv"; break; .... cout << _("Executing RPM (")<<operation<<")..." << endl; For the record: The exact same source has been used on suse-8.2 as well, and it did not show the problem. The compilation and execution has been performed with different LANG= settings. They do not seem to matter. The problem persist if cout is altered for cerr. If a "\n" is added to the variable operation as follows: case Item::RPMUpgrade: if (Interactive) operation = "-Uvh\n"; else operation = "-Uv"; break; ...... cout << "Executing RPM (" << operation << ")..." << endl; The output is now: Executing RPM (-Uvh@,¤E@è´B@0@8È¸çÿ¿0@ )... Or if the variable is assigned an empty string the following result is obtained: After unpacking 11.5kB of additional disk space will be used.

Is the definition of the variable incorrect, something else?? -- TIA, Richard Bos Without a home the journey is endless

Unable to buld umbrello
by Charles Kerr 09 Nov '03

09 Nov '03

I went to the uml.sf.net, after installed SuSE 9. I wanted to make some code modifications to umbrello, so get the latest cvs following instructions at uml.sf.net. When I did the configure --prefix=/opt/kde3 , it comes back with the following error: checking for Qt... libraries /usr/lib/qt3/lib, headers /usr/lib/qt3/include using -mt checking for moc... /usr/lib/qt3/bin/moc checking for uic... /usr/lib/qt3/bin/uic checking whether uic supports -L ... yes checking whether uic supports -nounload ... yes checking if Qt needs -ljpeg... no checking for rpath... yes checking for KDE... libraries /opt/kde3/lib, headers /opt/kde3/include checking if UIC has KDE plugins available... no configure: error: you need to install kdelibs first. Obivously I have kdelibs installed, kde is mydefault desktop, and I chose KDE development when I installed. Any thoughts appreciated!!!!! Charles

c++ problem
by Gedi 08 Nov '03

08 Nov '03

Hi all, I am very new to programming and am currently learning C++. At the moment I'm at the stage of structures and classes, so am writing many programs oriented around this to help. I have written a simple problem which I cannot get to run. Usually I have no big problems as the compiler aids me in debugging, however this program compiles and I am not up to the stage of using a debugging tool like GDB yet. My program seems to jump after asking the age and when complete gives very strange outputs. I can't paste an error report with this as there is no error, hopefully somebody can show me where I'm going wrong. Code as follows: #include <iostream.h> #include <string.h> struct students student_info(struct students data); void print(struct students data); #define MAX_STU 5 struct students { char name[30]; int age; char grade[2]; int iq; }; main() { students student[MAX_STU]; int i; //get the data for (i=1; i<=MAX_STU; ++i) { student[i] = student_info(student[i]); } //print the data for (i=1; i<=MAX_STU; ++i) { print(student[i]); } } struct students student_info(struct students data) { cout << "what is the students name: "; cin.getline (data.name, 30); cout << "What is the students age: "; cin >> data.age; cout << "What is the students grade: "; cin.getline (data.name, 30); cout << "What is the students IQ: "; cin >> data.iq; return (data); } void print(struct students data) { cout << "Name: " << data.name << endl; cout << "Age: " << data.age << endl; cout << "Grade: " << data.grade << endl; cout << "IQ: " << data.iq << endl << endl; } thanks Gedi

RE: [suse-programming-e] c++ problem
by Gedi 04 Nov '03

Hi Peter, Thanks for the input. That was a silly mistake on my part which I had overlooked. However, that was not the cause of the problem. I am thinking it has something to do with the area around 'cin >> data.age;' in the 'student_info' function, as this is where the problem occurs. However, I don't yet have the experience to pinpoint it. Thanks Gedi ---------------------------------- From: Peter Morreale ---------------------------------- You test in the "for" loops is wrong, it should be: for(i = 0; i < MAX_STU; i++) ^^^^^^^^^^^ By saying "<=" you are accessing students[5] which is out-of-bounds.
