Problem with installation using beta 1.0

[Mord]

Hi all, I've just recently installed Linux (sick of windows) and I've got most things up and running, including java sdk. Anyway I'm tryin to run the test app for lwjgl but i get the common library error that I've seen in the fAQ. I've tried a few solutions i've read on the forums but it still gives the same error. Here's my output for the command line:

mord@neo:~/Desktop/LWJGL/lwjgl$ java -cp .:res:jar/lwjgl.jar:jar/lwjgl_test.jar:jar/lwjgl_util.jar:jar/lwjgl_fmod3.jar:jar/lwjgl_devil.jar:jar/jinput.jar:-Djava.library.path=/home/mord/Desktop/LWJGL/lwjgl/native/ org.lwjgl.test.WindowCreationTest

Any help would be much appreciated.

thanks

due to the single file release and restructure, you should pass:
-Djava.library.path=/home/mord/Desktop/LWJGL/lwjgl/native/linux
instead

[Mord]

Heya, thanks for the reply. I tried that directory and I still get the same message. I was fooling around with LD_LIBRARY_PATH variable before(searching for answers to my problem not really knowing what i was doing). I'm not sure if this is a problem or not. Right now LD_LIBRARY_PATH is set too /usr/local/lib.

Thanks again for any help you can give me.

Just guessing - do linux libs extracted from the zip distribution have their UNIX executable permissions set?

If not, chmod +x and try again...

[Mord]

k, here's my latest attempt. I set executable permissions on the .so files

mord@neo:~/Desktop/LWJGL/lwjgl$ sudo java -cp .:res:jar/lwjgl.jar:jar/lwjgl_test.jar:jar/lwjgl_util.jar:jar/lwjgl_fmod3.jar:jar/lwjgl_devil.jar:jar/jinput.jar:-Djava.library.path=/home/mord/LWJGL/lwjgl/native/linux org.lwjgl.test.WindowCreationTest

Same problem, i think i set the executable permissions right.

thanks again

[Matzon]

try to ldd lwjgl.so

I noticed another thing:

In your transcript, -Djava.library.path setting appears to be appended to your -cp value. If that's true you're not setting any java.library.path at all (only a weird classpath).

What you want is:

java [blank] -cp [blank] <your:class:path> [blank] -D<your/lib/path> [blank] <mainClass>

-cp and -D are two separate options, -cp requires a blank between itself and a value, -D does not.

In fact, you don't need the colon ":" separator at the one of the classpath list (after jinput.jar).

[Mord]

ok, tried your suggestions but still get the same problem. Here is the lastest run:

mord@neo:~/Desktop/LWJGL/lwjgl$ java -cp .:res:jar/lwjgl.jar:jar/lwjgl_test.jar:jar/lwjgl_util.jar:jar/lwjgl_fmod3.jar:jar/lwjgl_devil.jar:jar/jinput.jar -Djava.library.path=/home/mord/LWJGL/lwjgl/native/linux org.lwjgl.test.WindowCreationTest

       at org.lwjgl.test.WindowCreationTest.main(WindowCreationTest.java:284)

and here's the ldd:

mord@neo:~/Desktop/LWJGL/lwjgl/native/linux$ ldd liblwjgl.so

Thanks again

[Matzon]

libjawt.so => not found

is the problem, it isn't finding the awt part of your java installation.

[Mord]

ok, i've tried fixin that by adding the libjawt.so directory to ld.so.conf file. But in Ubuntu dapper 6.06, i had to create the ld.so.conf file cause it doesnt use that file anymore. It still doesnt work after i did ldconfig. I'm not sure how else to link this file.

thanks again for any help

Mord

[Javapunk]

Do you have sun java installed?

[Mord]

ya, I installed sun JDK 1.5 update 6 (and re-installed just to make sure).

when I look at my library cache, it shows libjawt.so loaded :

libjawt.so (libc6, hwcap: 0x1000000000000) => /usr/lib/j2sdk1.5-sun/jre/lib/i386/libjawt.so

not sure why it's not seen by lwjgl

Mord

[Mord]

still lookin for a way to fix this. I'm not sure where to go from here.

thanks again for any help you can provide

[Matzon]

pretty clueless here - lwjgl works fine under Fedora Core 3+4+5 and Ubuntu latest

[ThorPrime]

Actually, I have noticed the same problem under the latest Ubuntu Dapper.

       linux-gate.so.1 =>  (0xffffe000)
       libm.so.6 => /lib32/libm.so.6 (0x55598000)
       libX11.so.6 => /usr/lib32/libX11.so.6 (0x555ba000)
       libXext.so.6 => /usr/lib32/libXext.so.6 (0x556a0000)
       libpthread.so.0 => /lib32/libpthread.so.0 (0x556ad000)
       libjawt.so => not found
       libc.so.6 => /lib32/libc.so.6 (0x556c0000)
       /lib/ld-linux.so.2 (0x56555000)
       libXau.so.6 => /usr/lib32/libXau.so.6 (0x557ef000)
       libdl.so.2 => /lib32/libdl.so.2 (0x557f2000)

I'm still looking for a solution as well.
