Just switched from KDE (which, incidentally, failed about daily) to Gnome. Two problems:
1. the default directory ‘MyEclipse 10’ doesn’t work because of the embedded blank. May have solved that by changing the dirname and refs to it in .ini and by adding a symbolic link ‘MyEclipse 10’ -> ‘MyEclipse10’ but then
2. IDE starts up and works fine until the window is (I think) deactivated. After that it becomes completely unresponsive. I think it is consuming messages, because Gnome doesn’t say it has stalled. But it won’t close, won’t repaint.
Nothing in the log to indicate a problem.
In case it is relevant, had to delete the lock file and had a double use problem while trying to fix this, but the IDE still starts fine: just won’t come back.

hamiljf,

The change in desktop shouldn’t have any effect on the file sytem and the embedded space shouldn’t make any difference, so I’m not sure what has gone wrong there. I installed and ran MyEclipse 10 on Ubuntu 11.10 fine, at the default location. If possible, could you try to unistall (or just delete the installed directory; you may also need to delete the directory pointed to by the .pulse2.locator file in your home directory, as well as deleting that file itself). Then run the installer again. The default location should be fine but you can change it, if you wish.

Make sure you have java installed before running the installer, or point to the JDK directory with the -vm argument on the installer.

Please let us know if that works for you.

I sorted it out as follows…
– removed the directories
– reinstalled
– created a symbolic link ME10 -> ‘MyEclipse 10’
– changed the execution command directory to point to ME10/myeclipse
and it seems to be running fine again
Would be a good idea to allow setting the install directory during installation to let the user remove blanks from the directory name, if necessary.

hamiljf,

As I say, the spaces should be fine. I have installed many versions of MyEclipse on Ubuntu in such directories.

The installer does allow you to change the install location. There are two parts to the install location, one directory is for the Common files (most of the files) and the other is for the specific release and edition of MyEclipse that you are installing. If the common files are already installed, the installer won’t let you change that (they will be in the location pointed to by the .pulse.locator file in your home directory, appended by /Common), but will allow you to change the location for the specific release and edition files.

You can install multiple releases together (which will all use the same Common location for most of the files), and install multiple instances of the same release (the installer will offer the choice to install another instance, if it detects it has already been installed). So you can experiment, if you want, without affecting your current install.

I’m curious as to why you think the installer doesn’t allow you to make changes to the location.

I thought I’d fixed this by doing what I thought was a clean re-install from scratch. But it doesn’t seem to have gone away. Present state is that I have 10.0 re-installed (from a saved copy of the download script) and a symbolic link to the ‘MyEclipse 10’ directory that is used only in the command line of a startup icon (to avoid problems with embedded blanks). Been running happily for a couple of days and suddenly in the middle of doing some source edits the IDE stalled: window would resize but not close and not repaint. After a while (several minutes) a JVM failure popup appeared and I got a screenshot and it is (hopefully) attached.
Can go round deleting hidden stuff and re-installing if it will help.

hamiljf,

Here is a link to an FAQ entry about how to do a clean install. Inside that FAQ is a link to another FAQ about a manual uninstall, if necessary.

I notice that you have installed the 64 bit version of MyEclipse. This is fine but I just wanted to note that with the 64 bit version, the recommended memory settings are:

-Xmx768m
-XX:MaxPermSize=384m

which can be set in the myeclipse.ini file.

As I’ve mentioned before, the embedded space should not cause a problem and has not caused a problem for me on either the earlier version of Ubuntu or the current version of Ubuntu, over many installations. I suggest a completely new install after getting rid of all installation directories and the .pulse2.locator file.

Again, you can alter the location of the installation during install, if you think the embedded space causes a problem on your system.

Thanks for this guidance. Failed again and this time (after quite a wait) produced messages about (you guessed it) space and also waiting for class loader. I’m now running with the larger space parameters and will post here only if it goes wrong again.
And btw, thanks again: you guys are quick and very helpful. You are really worth the licence fee.

hamiljf,

Thanks for the kind words; they are really appreciated. I’ll look for a further update from you on this.
