I installed Eclipse Neon yesterday and it seemed to be working fine. Installed a few plug-ins and did some work.
Today when I start it I get the following error message:
$ /usr/local/bin/eclipse46
/root/.p2/pool/plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.400.v20160518-1444: cannot open shared object file: Permission denied
I found some references in the config.ini file to the root folder (I have no idea why). I have correct these and the file now looks like:
#This configuration file was written by: org.eclipse.oomph.p2.internal.core.AgentImpl

However, I am still getting the "permission denied" error. Is there any way of correcting this?
I tried to put my user's folder to eclipse.ini file, and this didn't worked.
--launcher.library ~/.p2/pool/plugin /org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.400.v20160518-1444
seems the best approach for now is to copy the folder inside root home to your user, once its create with the the new installer.

I'm trying to use OProfile on Eclipse (3.8). The Juno version of oprofile didn't work, so I installed the Luna one. This one at least starts up, but can never find the libraries.
Here is the error:
ns3-dev-lena-profiling-debug: error while loading shared libraries: libns3-dev-lte- debug.so: cannot open shared object file: No such file or directory
profiled app exited with the following status: 127
I know that that means I need to add the library path. So I went to Profiling Tools Configurations, and specified the path under environmental variables as:
name: LD_LIBRARY_PATH
value: {workspace_loc:ns3dev2}/build (appended)
I manually checked and the library is located in the build folder. Furthermore, this library path works fine if I debug the same project instead (or run it...).
I've deleted the configuration and remade it, but it's the same error.
I also tried adding the same path to PATH instead of LD_LIBRARY_PATH, but that doesn't make any difference. (Just tried it for the hell of it).
Any thoughts?
Edit, I get the same problem on Eclipse 4.4 (Luna). I found the logs for the errors and the error is:
!ENTRY org.eclipse.linuxtools.oprofile.core 4 0 2014-10-27 12:33:07.200
!MESSAGE opreport process error output: warning: /no-vmlinux could not be found.
I'm a bit of an amateur developer and I'm currently messing around with JavaCV and Eclipse on my Mac.
I'm trying to get the FaceRecorgnition to work but I don't really know how to install this into Eclipse properly.
I've created a new Java Project, and I've imported the 'JavaCPP', 'JavaCV-Mac', and 'JavaCV' libraries.
I then created a package and called it 'mvn', then created a class and C/P the 'FaceRecorgnition' java into that class and then try and run it. I then get this error:

I don't fully understand imports and SDKs fully yet, so be easy.
Thanks.
This is not about missing libraries, but a missing .txt file.
It seems like the all10.txt file is not included in the JavaCV download.
Check out http://www.shervinemami.info/faceRecognition.html under the heading
"How to use the offline cmd-based FaceRec system:"
You find the all10.txt file in his zip facerecExample_ORL.zip and the faces needed in the zip
Cambridge_FaceDB.zip
Create a data folder where FaceRecognition.java is.
Put the .txt files in that folder as well as the Cambridge_FaceDB folder:
samples/
FaceRecognition.java
data/
all10.txt
Cambridge_FaceDB/
I got a very strange error. This what I've done:
I create a project (with Netbeans) which include datanucleuse-core-3.0.0-release.jar. The project can be built successfully. It also ran smoothly when I tried to run it with Netbeans or running 'java -jar <.jar bundle>' in dist folder via command prompt.
The problem is, when I copy that dist folder into another location and tried to run it again with command prompt, it gave these errors:
Exception in thread "main" Error reading manifest file

Anybody got clue ?
I am really sorry for everyone, especially for datanucleus members in StackOverflow.
Apparently the problem is me, not the netbeans, datanucleus API, nor anyone.
As you can see from "jar:file:/E:/!new/BTJ/NCRServer/lib/datanucleus-core-3.0.0-release.jar!/plugin.xml", I put the "dist" folder from Netbeans in "E:/!new" folder. I don't know why but the "!new" folder seems to cause the extra exclamation mark(!) in "release.jar!".
I move the dist folder into D:/ and it worked !!
So, if anyone ever experience this problem (precedence a folder's name with exclamation mark and accidentally put a project with datanucleus-core-3.0.0-release.jar inside it), that's the solution.
Thank you.
we are using PDFlib for personalizing PDFs.
The pdflib.jar library and the libpdf_java.so file are both in the folder:
/home/user/my/custom/library/path/
I start the server with this argument:
java -Djava.library.path=/home/user/my/custom/library/path/
like it is mentioned in the pdflib tutorial
After deploying on my jBoss5 Server i got this error message:
ERROR [STDERR] Cannot load the PDFlib shared library/DLL for Java.
Make sure to properly install the native PDFlib library. For your
information, the current value of java.library.path is:
/home/user/my/custom/library/path/
So, the path ist correct (i tried it with and without the / at the end)
If I put the jar and the lib in my /usr/lib folder, everything works fine, but not with my custom folders.
I use it on a linux 64bit, if that matters!
The custom folder and the files got chmod 755 - so this shouldn't be the problem
Looking forward to your hints!
I have tried ensime/sbt on mac os. First, I open the .scala file in project folder create from using sbt in command-line, then I ran ensime and it still work fine, but whenever I run ensime-sbt (c-c c-v s), I got

Error during sbt execution: java.io.IOException: No such file or directory
Process sbt exited abnormally with code 1
I tried using sbt from command-line and everything works from there (compile/run/console). I'm using sbt 0.10.1 and latest binary ensime on emacs24 (2011/07/24) on mac os.
Any idea that I'm doing it wrong ?
I had this and after applying strace I found the issue. The ensime-sbt.el function searches up from the cwd looking for ./project/build.properties. On finding this dir/file it assumes this is the root directory.
So just create this file and this issue should disappear. Would be nice if ensime created this file by default seeing as it's a required file for the sbt function to work.
I got the same error. This situation seems to be that sbt tried but failed to create ".sbt" and ".ivy" dir at the user's home directory. Maybe, the reason is that OS user doesn't have permission to write at the user's home directory.
It's something related with permission, maybe.
I checked the Locks.scala https://github.com/harrah/xsbt/blob/0.10/launch/Locks.scala source, and guessed "file.getParentFile.mkdirs()" did no work because of permission denial.
I encountered the same problem yesterday, and got it run a minute ago, by adding sudo:
"sudo emacs xxx.scala"
you can change sbt.ivy.home and ivy.home property. So, to augment Joachim's first solution, you would set both system properties:
like this:
java -Dsbt.ivy.home=/tmp/.ivy2/ -Divy.home=/tmp/.ivy2/ -jar dirname $0/sbt-launch.jar "$#"
hope to resolve you problem
This error also occurs when the files in the home directory that sbt tries to access are not owned by the user that tries to run it. run a chmod 777 on the directoris in the home master and the issue will be solved.
