pkg-config SUSE standard place & sylpheed-claws
by Ivan Sergio Borgonovo 09 Dec '03

I was having a hell of time trying to compile sylpheed-claws 0.9.7. Now it is working but without ghostscript plugin. gtk(1/2), glib(1/2) problems seems solved. I noticed that PKG_CONFIG_PATH point to /opt/gnome/lib/pkgconfig. Then I noticed in the original didge's .spec rm -rf $RPM_BUILD_ROOT%{prefix}/include/sylpheed rm $RPM_BUILD_ROOT%{prefix}/%{_lib}/pkgconfig/sylpheed-claws.pc and %{prefix} points to /usr/X11R6/ The new configure.ac of ghostscript plugin 0.6 need the .pc file and it seems to need the include dir too. Furthermore the generated sylpheed-claws.pc file seems not suited for SUSE 9.0... The idea was to just "move" sylpheed-claws.pc where SUSE's pkg-config expect it. But I was wondering how many things I'm going to break. I gave a look to mmj's The SuSE Package-Conventions but didn't find anything that should point me to adopt the most standard/lasting solution.

Dear my friends.... I did make a connection to MySQL with Java through JDBC. Also executing the query (select * from customer). But I don't know how to use the result of the query. in PHP I use : " $row=mysql_fetch_row($result); list($customerid, $fullname)=$row; " Please give me the example to extract the result into the variables those I can use in my furthere code. Here is the result: " patrixlinux@patrix:~/arsip/My/comadmin> java customer Here is customer menu Connection established com.mysql.jdbc.ResultSet@1aaa14a " Thank you very much in advance. __________________________________ Do you Yahoo!?

Clearing the diplay with JAva.

Dear my friends... First time I use Java, I feel as if I am in new world. I want after the user choose one of menu in main menu than the displayed is cleared (blanken) and come the aimed menu. Can I use another class for this implementation? I mean like modular programming. I make one file as the main menu (comadmin.class) and some other files to represent each of the options in the main menu (such as : customer.class, product.class,etc). How can I do that? Thanks in advance. ps : here is my simple code for the detail of my explanation. ================= public class comadmin { public static void main(String[] args) { int pilihmenu; System.out.println("========================================="); System.out.println("| Main Menu |"); System.out.println("========================================="); System.out.println("| Options : |"); System.out.println("| 1. Customer |"); System.out.println("| 2. Product Field |"); System.out.println("========================================="); pilihmenu = Keyin.inChar("Please choose (1-2) : "); switch (pilihmenu){ case '1' : System.out.println("Opening customer menu\n"); customer; break; case '2' : break; } } } __________________________________ Do you Yahoo!?
