mysql2postgres has no documentation?
by Prabu Subroto 30 Jun '04

30 Jun '04

Dear my friends... I am trying to nigrate my database from mysql to postgres. I have dump my databases qith mysqldump and put the result in a file ( named basisdata ). In order to make it be possible to be reloaded with psql, I want to convert the file with "mysql2pgsql.perl" tool. But I don't know the syntax. I tried this : " mysql2pgsql.perl basisdata " But lookslike it's wrong. Anybody would be so nice to tell me which command I should execute to convert the file into psql familiar format? Thank you very much in advance. __________________________________ Do you Yahoo!? Yahoo! Mail - 50x more storage than other providers! http://promotions.yahoo.com/new_mail

unknown IDE
by Cyprien Simons 29 Jun '04

29 Jun '04

Hi everybody, I'm trying to work on an old project which was not touched anymore since one year. The guy who did it is not joinable, and the documentation... well... is not the best I've ever seen. :( So here I am: I know that the guy was working on SuSE, and I got a .proj file in the project repertory (I know, it sounds like a cluedo...). I've a little bit searched on the web, but the only repertoried applications creating .proj files are NeXT Interface Builder (Mac) and a molecule simulator - which is absolutely not matching... So, I tried to open it with Kdevelop 3.0.4 and the latest Gambas, but unsuccessfully. Thus, I was wondering if you guys had any idea of which programming environment I could try... Thanx. Cyprien

Parent window is frozen after workspace filled with a child form.
by Prabu Subroto 29 Jun '04

Dear my friends... I am using QT Designer from SuSE 9.1 to create a database application. I made it to load a child (QDialog, custbaruForm) form into a parent form (MDI Window, depanForm). But after the child form displayed, the parent window is frozen. I can not do anything on the application. I close the application with xkill.

Looking for a -devel version of gtkglarea
by Ned Horning 29 Jun '04

29 Jun '04

Greetings, I am trying to run a program that requires the gtkglarea development package. I have Suse 9.1 that comes with gtkglarea-1.2.2-889 but not the -devel version. It is not on the CD or the Suse ftp site. Can someone let me know where I can find this version of the development package or let me know if there are some alternatives to deal with this. I searched the internet and found other versions but have been told that it is wise to use the same version for the development and library releases. I am new to Linux so any help would be appreciated. Ned

KDevelop 2.1 and SuSE 9.1
by Maura Edelweiss Monville 29 Jun '04

29 Jun '04

Since I'm experiencing some problems at compiling with KDevelop 3.0 a project imported from KDevelop 2.1 and since I'll be installing SuSE 9.1 on my new PC ... I wonder whether I can have KDevelop 2.1 running on SuSE 9.1 ... The latest KDevelop version is not so nice and fancy as the latest one but it works for me .. no headache .. Thank you. Maura

g++ and VC 2003
by Filippos Papadopoulos 29 Jun '04

29 Jun '04

Hi. I am developing a 3d application in SuSE Linux 9.0 in C++. I ported the application in WinXP using VStudio2003. The fun stuff is that the application executes in Linux but it crashes immediatelly in WinXP. I think i found what is causing the segfault in windows. I have the following classes (which are bad-coded by the way ;) : class Vertex3d { public: double x,y,z; long num; Vertex3d() { x = 0; y = 0; z = 0; num = 0; } /* Creates a new instance of Vertex3d */ Vertex3d(double x_,double y_,double z_,long num) { x = x_; y = y_; z = z_; this->num = num; } int draw() { glBegin(GL_POINTS); glVertex3d(x, y, z); glEnd(); return 0; } int draw(double px,double py,double pz) { glBegin(GL_POINT) glVertex3d(px, py, pz); glEnd(); return 0; } double distance(Vertex3d t) { return sqrt(pow(((Vertex3d)t).x - x , 2) + pow(((Vertex3d)t).y - y , 2) + pow(((Vertex3d)t).z - z , 2)); } }; #include "Vertex3d.h" class Cone { public: GLuint selectionName; bool isSelected; Vertex3d bottomCentre; double bottomRadius; Vertex3d topCentre; double topRadius; float* vertices1; float* vertices2; float* Upper; float* Lower; float *table; Cone() { ; } Cone(Vertex3d bottomCentre, double bottomRadius, Vertex3d topCentre, double topRadius) { this->bottomCentre = bottomCentre; this->bottomRadius = bottomRadius; this->topCentre = topCentre; this->topRadius = topRadius; selectionName = 0; isSelected = false; vertices1 = (float *)malloc( sizeof(float) * 2 * (30 + 1) ); vertices2 = (float *)malloc( sizeof(float) * 2 * (30 + 1) ); Upper = (float *)malloc( sizeof(float) * 3 * (30 + 1) ); Lower = (float *)malloc( sizeof(float) * 3 * (30 + 1) );; } }; In the begining of the main.cpp i do the following: float x=2.0, y=6.0f, z=1.5; Cone cone1(Vertex3d(10*x, 0, 10*z, 100), 1, Vertex3d(10*x, 0, 10*z+5, 2), 0.00); Cone cone2(Vertex3d(9*x, 0, 9*z, 100), 0.7, Vertex3d(9*x, 0, 9*z+3, 2), 0.00); Cone cone3(Vertex3d(9*x, 0, 11*z, 100), 0.7, Vertex3d(9*x, 0, 11*z+3, 2), 0.00); Cone cone4(Vertex3d(11*x, 0, 9*z, 100), 0.7, Vertex3d(11*x, 0, 9*z+3, 2), 0.00); Cone cone5(Vertex3d(11*x, 0, 11*z, 100), 0.7, Vertex3d(11*x, 0, 11*z+3, 2), 0.00); I think that the previous declarations cause my app to crash in WinXP. Why does this happens in WinXP although the app runs in Linux? thanks.
