| rivers22_ | hello everyone....I need some help | 00:20 |
|---|---|---|
| rivers22_ | I've been trying to get java-gnome working | 00:21 |
| rivers22_ | every time I try to run my app an exception java.lang.UnsatisfiedLinkError: no gtkjni-4.0 in java.library.path | 00:23 |
| rivers22_ | I can't get it to work | 00:24 |
| persia | I suspect that this requires the installation of libjava-gnome-java, but wonder why we also have libgtk-jnu and lingtk-java-dev. We do need to clean up the duplicates one of these days. | 00:26 |
| rivers22_ | I need help with java-gnome!!! | 00:32 |
| rivers22_ | I can't get it to work properly | 00:32 |
| rivers22_ | Every time I try to run an example or my own code it an exception is thrown saying that there is no gtk-4.0 in java library.path | 00:34 |
| persia | rivers22_, You need to install libjava-gnome-java | 00:34 |
| persia | rivers22_, Next time you get a similar error, you can use a command like `apt-file search gtkjni` to find out which package you need. | 00:34 |
| rivers22_ | I can't find libjava-gnome-java in synaptic???? | 00:36 |
| persia | Ah. It seems to only be in 8.10 beta. Sorry. You might try libgtk-jni, but that only provides libgtkjni-2.10.s0 | 00:38 |
| rivers22_ | Okay I have it install | 00:39 |
| rivers22_ | I have libgtkjni-2.10.so and libgktjni.so in /usr/lib/jni/ and libgtkjni-4.0.so in /usr/local/lib | 00:42 |
| rivers22_ | how could i set gtkjni-4.0 in java.library.path??? | 00:43 |
| rivers22_ | when I run the java-gnome "make demo" it runs perfectly but when I try to compile and run it manually it does not work.... | 00:45 |
| persia | Now you've gotten outside of what I know well enough to help. Sorry. | 00:47 |
| rivers22_ | do you have java-gnome working? | 00:48 |
| persia | No, but I also don't have it broken (I've not tried to play with it) | 00:49 |
| rivers22_ | okay, so are you using and IDE to program in java? | 00:50 |
| persia | No. | 00:50 |
| persia | I play with netbeans some, but I haven't done any significant development in Java in some time. | 00:50 |
| rivers22_ | what programming language do you use if I may ask?? | 00:51 |
| persia | Mostly make. A bit of shell. | 00:52 |
| persia | I tend to do packaging, and merging of patches. Not so much development of code. | 00:52 |
| persia | Some of that is for Java, so I hang out here, and sometimes have useful things to say, but not once it gets into real code. | 00:53 |
| rivers22_ | is that more difficult than development code?? I've never done any packagin or merge any patches..... | 00:54 |
| persia | For code questions, I usually recommend people visit ##java, but it seems like you have something in-between a code issue and an issue with how java-gnome is installed in Ubuntu, so I don't know if you are in the right place. | 00:54 |
| persia | It's mostly different, rather than being either easier or more difficult. | 00:54 |
| persia | Most of it is like plugin development : you know the system that will be calling the code, so you write to a given set of callbacks and make sure you are in the correct state at each point. | 00:55 |
| persia | Instead of corresponding to interpretation of mouse/keyboard/video stream/etc. events, the callbacks are things like "compile package", "install package", "remove package". | 00:56 |
| rivers22_ | don't you have to code all of those instructions in a language??? | 00:57 |
| persia | Yep. Like I said, mostly make or shell. | 00:57 |
| rivers22_ | hey do you know why is taking so long for the apt-file to update??? I've just install it and ran the apt-file update command but it seems its taking a lot of time.. | 00:59 |
| persia | It needs to download a list of every file in each of the 20,000 packages. Takes a while. | 00:59 |
| persia | After this, it's *really* easy to find which package has stuff, but the first update is slow. | 01:00 |
| rivers22_ | Okay, that's good to know, I was getting worry..... | 01:00 |
| persia | Once you've updated the first time, it shoulld be quicker, as later updates are only updating the lists in the security or updates repos, so a few hundred packages at most, rather than all 20,000. | 01:00 |
| rivers22_ | okay the apt-file update has finish... i run the apt-file search gtkjni command and I got back this: libgtk-java-dev: /usr/lib/jni/libgtkjni.so libgtk-jni: /usr/lib/jni/libgtkjni-2.10.so | 01:06 |
| rivers22_ | but I already have them install, what I need to know is how to set the java.library.path | 01:07 |
| persia | Right. Those are the two packages that contain files containing "gtkini", so it's likely that one or both of them are the ones you want. | 01:07 |
| persia | Don't you just pass a CLASSPATH to javac? | 01:07 |
| rivers22_ | yes, that's what i've been doing | 01:08 |
| rivers22_ | okay I got it working!!!!!! yeah!@@! | 01:13 |
| persia | Cool! Nice job. | 01:15 |
| rivers22_ | I just had to use -Djava.library.path=/usr/local/lib and then -classpath | 01:15 |
| rivers22_ | okay well thanks, this is the first time I've use IRC, it's pretty cool....thanks a lot persia you're a genius!!! | 01:32 |
