The problem in omnetpp-5.4.1 installation.
I have successfully done the entire process of downloading OMNeT++. While writing OMNeT++ to enter into the IDE I am getting this error:
An error has occurred. See the log file
/home/abc/MySoftwares/omnetpp-5.4.1/samples/.metadata/.log.
Use OMNeT++ 5.5.1. Recent versions of debian updated java to version 11 which is not compatible with the Eclipse version in omnet 5.4.1.

Since an unexpected power loss a while back (my computer just went off) I'm getting this pesky warning from Android Studio at launch:
/!\ External file changes sync may be slow
File watcher failed repeatedly and has been disabled
I understand the message, but I have no idea what I should do about it. Apart from that warning I have not experienced system instability. Running on Ubuntu 20.04.
If you go to Help - Collect Logs and Diagnostic Data you'll get a zip file containing (among others) idea.log, which should contain the error.
Probably you'll find this: /lib/x86_64-linux-gnu/libc.so.6: version GLIBC_2.33' not found` which indicates some component is compiled against a libc version newer than what is in Ubuntu 20.04.
If this is the error you get there's not much you can do except upgrading Ubuntu to a newer version.
I was following the installation manual for presto.
But when I lanched the presto server from the command line I got this error:
$ bin/launcher run
Unrecognized VM option 'ExitOnOutOfMemoryError'
Did you mean 'OnOutOfMemoryError=<value>'?
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Per #kavehmb's answer on another question, as of June 2019 the way to work around this issue is:
brew tap adoptopenjdk/openjdk
brew cask install adoptopenjdk8
I suspected the java version was wrong and checked it. I had Java 1.8.0_65-b17.
The documentation for the installation did not mention anything about needed java version. It was hard to find out the needed Java version for the newest Presto version (v0.208)
I updated to the currently newest Java8 version using brew (on Mac).
brew cask install java8
After successful upgrading of Java I had version 1.8.0_181-b13.
Then prestodb could start.
I'm trying to do IBM Bluemix essential course.
As per the course instructions, I installed Eclipse (I initially got latest Eclipse version Neon instead of Mars but tried both Mars and Neon as of now for installing NodeEclipse .17, 1.0.1 or 1.0.2 or Enide.p2f file using both File import and Eclipse marketplace for installing Enide.p2f Node eclipse plugin in Eclipse).
One of the instruction (after installing IBM Bluemix plugin for eclipse) says, I need to install "Enide.p2f Eclipse NodeJS plugin" https://marketplace.eclipse.org/content/enidep2f-eclipse-nodejs-ide
I tried Eclipse Marketplace to install this. Searched "node eclipse" and selected the top listing entry for "Nodeeclipse 1.0.2 Nodeeclipse Core & Node.js (nodeeclipse-1)" or even "Enide.p2f for Nodeeclipse 1.0.1" version and clicked installed.
A couple of times, if failed during the resolution process to list the plugin components and Eclipse error log showed that the update site / repository server was not available.
Another method was to install the .p2f file directly File > Import > Install > Install from a file and selected the downloaded .p2f file which I got from here: https://raw.github.com/Nodeclipse/eclipse-node-ide/master/ENodeIDE.p2f
or
http://marketplace.eclipse.org/content/enide-eclipse-nodejs-ide/click
Using the import > install via file method, I'm getting "Unhandled event loop exception" error message as per Eclipse Error logs and it didn't install anything.
Using the market place method, I'm getting the following error mesg (per the screen shot):
For Nodeeclipse 1.0.1

it shows the Enide.p2f .17, 1.0.1 or 1.0.2 (Whichever you select from the list) to install the plugin:

With Eclipse Mars, I'm getting the same behavior. More info on this can be found here as well: https://www.ibm.com/developerworks/community/forums/html/topic?id=76a96fa4-1086-41a7-94a6-4326f79dfacb&ps=#repliesPg=0
Did anybody else face this similar issue and what should i do to resolve it.
"https://marketplace.eclipse.org/content/enidep2f-eclipse-nodejs-ide"looks like an update site so I tried the Help->Install New Software... I then entered the address as a new update site but it failed as well...
I am not sure if it is the right place to ask this question. I have been trying to install clearcase client 8015 on a new machine with RHEL5u8 image. Tried googling a lot but could not resolve the issue as per suggestions on other forums.
It gets installed successfully. (As per the prompt)
listing of the views is done properly. (cleartool lsview)
When I do cleartool mount -all,
cleartool: Error: The MVFS file system is not installed or not loaded,
or the 'viewroot' is not mounted or is inaccessible: not a ClearCase
object.
logging in as root then starting clearcase, executing "/opt/rational/clearcase/etc/clearcase start"
OUTPUT:-
ClearCase is stopped Starting ClearCase ClearCase daemons: albd_server
FATAL: Error inserting mvfs
(/lib/modules/2.6.18-308.4.1.0.1.el5/kernel/fs/mvfs/mvfs.ko): Unknown

---- Please review /var/log/messages for information on the problem.
---- You may need to rebuild your kernel, rebuild your mvfs module,
---- and reboot your system. Information on how to do this can be found in

I have followed all the steps in /var/adm/rational/clearcase/mvfs/mvfs_src/README.txt but still cannot achieve anything.
Uninstallation also fails as:-

Cannot proceed with installation, cannot uninstall either to try another version of clearcase, tried googling for the version mismatch of IBM installation manager but could not find anything addressing the issue properly for Linux.
Any suggestions on how to proceed? I am new to clearcase tool.
Usually, when I see only snapshot views are supported, and MVFS (for dynamic views) hasn't installed properly, I uninstall everything and try the all process from the start again.
In your case, that means installing or downgrading the IBM IM Installation Manager to the right version (similar to this issue).
It can be an IM update issue, as seen in this technote.
Further to #VonC's comment re: incompatible IM install,
review the following doc: MVFS not loading after kernel upgrade or is missing after installation on Linux.
I encountered a similar problem after an incompatible kernel path / ClearCase version. In my case, the error was similar to what is documented here in the post MVFS not installed - RHEL6 and I had to edit the kernel source to the same as the patch and rebuild. Then things stared up fine.
Review also the link How to manually restore a pre-built MVFS on Linux.
If the corresponding kerenl level is not provided it will not start and you will have to patch and make your own.
I used to run a few Windows applications via Wine 1.4.0 (installed through homebrew) on OSX Mountain Lion and after I updated to 1.4.1 (again via homebrew), I get the following error whenever trying to run any windows application:
wine: failed to initialize: dlopen(/usr/local/Cellar/wine/1.4.1/lib/wine/ntdll.dll.so, 258): image not found
Any ideas about how to fix it?
That's clearly an installer/packaging/homebrew problem, has nothing to do with wine itself.
