FLLinux · 02-02-2005, 09:26 PM

I just installed FC3 and i am trying to get eclipse to run on it. I know that there must be an answer to this somewhere.

When i run the eclipse command this is the error that i get.

Thanks

Hi Guys,

I could not answer this questions because I have the same problem too.

Please Help us. Thank you...

You need to tell the system where the eclipse libs are located. The easy way is to run

Code:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/eclipse

if /usr/eclipse is where you have it install, and then run eclipse.

If that works you should add that line to your /etc/profile. Look here for details http://www.csfalcon.com/wiki/csfalcon/EclipseIDE

hi friends i have been using fedora core 3. This systen hava java and javac command when i set up the FC3 . But eclipse can't run please help us

thank you for your contribition...

csfalcon · 02-09-2005, 10:24 AM

FC3 has either a place holder for java and javac or the gcc java, I'd recommend installing the Sun's JDK and replace those place holders. Here are the instructions for installing Java and Eclipse.

Java SDK
Eclipse IDE

FLLinux · 02-12-2005, 10:47 AM

Installing the actually Java JDK from Sun work great. Thanks csfalcon.

Just one think, after installing the JDK you also need to change the location that the /usr/bin/java link is pointing to. Need to move it from the script file to the location where the actually JDK was installed.

Thanks again.

dafatdude · 02-21-2005, 10:27 PM

Hi guys,

I have been having that very same problem but i fixed it now.
Make sure you check which version of java is being used.

Code:

which java

Mine displayed

Code:

/usr/bin/java

which was a symbolic link to the wrong place.

You have to make sure that the java displayed is the one which lives in your Java SDK directory.
This can be achieved by exporting the java path to the /etc/profile.

Code:

export PATH=$PATH:/usr/jdk*/bin

Mine worked fine after that.

Thanks guys,

Hi Guys,

i also got a problem with running eclipse with FC3. I installed the java sdk and eclipse. When I am trying to start eclipse I get the following error:

JVM terminated. Exit code=1
/usr/bin/java
-cp /home/armbrusterr/eclipse/startup.jar org.eclipse.core.launcher.Main
-os linux
-ws gtk
-arch x86
-showsplash /home/armbrusterr/eclipse/eclipse -showsplash 600
-exitdata /home/armbrusterr/eclipse/eclipse -exitdata 17800f
-vm /usr/bin/java
-vmargs
-cp /home/armbrusterr/eclipse/startup.jar org.eclipse.core.launcher.Main

I tried to change the PATH to the correct location (/usr/java/j2sdk1.4...../) with this:

Code:

export PATH=$PATH:/usr/java/j2sdk1.4.2_07/bin

but when I use

Code:

which java

it still answers /usr/bin/java

Thanks for your help.

PATH=$PATH:/blah/blah

sets /blah/blah to the last directory searched in the PATH. So if /usr/bin is before your entry ( which it will be), it will be picked up first instead of what you want.

export PATH=/blah/blah:$PATH

sets /blah/blah to the FIRST directory searched, so it will be searched before /usr/bin. Under bash, this syntax is true on all paths so they work the same ( by all paths I mean others like PKG_CONFIG_PATH, LD_LIBRARY_PATH, etc...).

TiMDoR · 03-01-2005, 02:23 AM

oooooh...

not really clicking on any of those posted links, but i spent HOURS trying to get eclipse running in FC3 but considering how slow it runs in windoze, it was worth it...

so after hours of doing everything the long way and searching through the eclipse wiki and bugzilla i saw a reply that simply said "why don't you just make a launcher?" and at that point i wasn't sure whether to laugh or cry...

so make yourself a custom launcher and point it to where you've got eclipse.exe hiding, and then in the command line add minus the quotes "-vm /usr/share/j2dk1.5.0/jre/bin/java.exe" or where ever you happen to have the java installed to...

plus since eclipse uses it's own compiler you'll want to stay away from using javac the default sun java compiler...

easy no?

ebo · 03-01-2005, 02:56 PM

Hi again,

I tried to set the Path like this:

Code:

export PATH=/usr/java/j2sdk1.4.2_7/bin:$PATH

when I check the config with :

Code:

which java

I get the following result:

Code:

/usr/java/j2sdk1.4.2_07/bin/java

I thought this might be some kind of bug or anything like that so I tried to start eclipse.... and got my same old problem:

Code:

JVM terminated. Exit code=1
/usr/bin/java
-cp /home/armbrusterr/eclipse/startup.jar org.eclipse.core.launcher.Main
-os linux
-ws gtk
-arch x86
-showsplash /home/armbrusterr/eclipse/eclipse -showsplash 600
-exitdata /home/armbrusterr/eclipse/eclipse -exitdata 12800d
-vm /usr/bin/java
-vmargs
-cp /home/armbrusterr/eclipse/startup.jar org.eclipse.core.launcher.Main

Any more ideas?

Thanks for your help.
