[need help] ubuntu jpcsp

[wingnux]

Sorry for the dumb question but how should I do that? Thanks in advance?

[kokusho]

I had the same problem, seem that jpcsp don't work with java 7 (both oracle and openjdk) on ubuntu,
if you uninstall it and try with java 6 openjdk or with java 6 sun (with jdk package) everything will work

Edit the 2nd line of start-linux-amd64.sh with

Code:

java -Xmx1024m -XX:MaxPermSize=128m -XX:ReservedCodeCacheSize=64m -Djava.library.path=lib/linux-amd64 "-Dorg.lwjgl.librarypath=$0/../lib/linux-amd64" -jar bin/jpcsp.jar

(this will only work inside the script, not directly on the command line)

[wingnux]

Same error:

Edit:

wingnux@wingnux-desktop:~$ locate liblwjgl.so
wingnux@wingnux-desktop:~$

I don't think I have this library on my system and I'd performed a "sudo updatedb" before trying to locate liblwjgl.so.

Same error:

then try to hardcode the absolute path from your system (the path you see when calling "pwd"):

Code:

java -Xmx1024m -XX:MaxPermSize=128m -XX:ReservedCodeCacheSize=64m -Djava.library.path=lib/linux-amd64 "-Dorg.lwjgl.librarypath=/.../jogos/jpcsp-linux-amd64/lib/linux-amd64" -jar bin/jpcsp.jar

These are the libs on the jpcsp directory:

wingnux@wingnux-desktop:~/jogos/jpcsp-linux-amd64$ ls ~/jogos/jpcsp-linux-amd64/lib/linux-amd64/
libjinput-linux64.so liblwjgl64.so libopenal64.so

Tried copying liblwjgl64.so to liblwjgl.so and it didn't work either.

[hyakki]

have you checked permissions ?
ls -al /jogos/jpcsp-linux-amd64/lib/linux-amd64/

make sure its readable by your user/group if not then

chmod 755 -R /jogos/jpcsp-linux-amd64/lib/*

if it still fails try
ldd /jogos/jpcsp-linux-amd64/lib/linux-amd64/liblwjgl.so
see if you are missing anything it needs.

[wingnux]

Permissions are ok and even after applying chmod -R 755 it still crashes.

Here's the ldd output of liblwjgl64.so:

As said before, there's no liblwjgl.so on the lib directory, only liblwjgl64.so.

[hyakki]

hm not sure if it will help maybe try making a symbolic link to both filenames (you might need to use full paths)
ln -s liblwjgl64.so liblwjgl.so


you could also try to set the global path
export PATH=$PATH:/jogos/jpcsp-linux-amd64/lib:/jogos/jpcsp-linux-amd64/lib/linux-amd64

[gid15]

From the source code, LWJGL is trying to load liblwjgl64.so and if it fails, it is trying with liblwjgl.so. If that one fails again, it is displaying the error message about liblwjgl.so.
Despite of the error message, the main issue is however that liblwjgl64.so cannot be loaded... at least, this is what I understood from their source code...
