I've installed ensime according to the README.md file, however, I get errors in the inferior-ensime-server buffer with the following:

Also none of the type identification works for me, I get 'NA' if I get anything at all. C-c t causes emacs to lock up.
I'm running:
Ubuntu 10.04 (64bit version)
emacs 23.1.50.1
ensime from git (as of 3 May 2010)
scala is version 2.8.0.RC1
java is 1.6.0_20 (from sun)
here is a copy of the log: http://dl.dropbox.com/u/5309017/ensime.log
Thanks!

"scala.tools.nsc.MissingRequirementError: object scala not found" usually means that the standard Scala libarary cannot be found. Have a look at the inferior ensime server buffer, and it should print the classpath that's being used. Here's an excerpt from mine:
INFO: [Classpath = /usr/lib/jvm/java-6-openjdk/jre/lib/resources.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/rt.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/jsse.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/jce.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/charsets.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/rhino.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/ext/dnsns.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/ext/pulse-java.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/ext/sunjce_provider.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/ext/sunpkcs11.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/ext/localedata.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/ext/gnome-java-bridge.jar:/home/aemon/src/misc/ensime/lib/jnotify/jnotify-0.93.jar:/home/aemon/src/misc/ensime/lib/scala/scala-library.jar:/home/aemon/src/misc/ensime/lib/scala/scala-compiler.jar]
Notice the scala-library.jar, second from the end. You probably have to modify your .ensime file so that the :classpath field points to the library jar.

I want to setup a private tangle on my own virtual machine with Ubuntu 18.04, 4GB RAM and 20GB memory.
I have follow this instructions: https://docs.iota.org/docs/compass/0.1/how-to-guides/set-up-a-private-tangle. Every command works fine until reach this one: bazel run //docker:layers_calculator.
It shows an error as follows:
Starting local Bazel server and connecting to it...

How can I solve this problem? what I have missed?
read carefully the message given after running bazel installer:
Make sure you have "/home/yourusername/bin" in your path. You can also activate bash completion by adding the following line to your :
source /home/yourusername/.bazel/bin/bazel-complete.bash
You can check with: "bazel info" or "bazel version"
Unfortunately, there are further errors:
https://github.com/iotaledger/compass/issues/142
I have solve this issue by using this commands:
Step 3: Set up your environment
If you ran the Bazel installer with the --user flag as above, the Bazel executable is installed in your $HOME/bin directory. It’s a good idea to add this directory to your default paths, as follows:
export PATH="$PATH:$HOME/bin"
You can also add this command to your ~/.bashrc or ~/.zshrc file to make it permanent.

I'm facing a strange behavior whenever I invoke an error in boot-cljs-repl. The repl (actually the entire emacs) hangs for about 15 seconds and after that I see the following error message below the mode-line:
error in process filter: Lisp nesting exceedsmax-lisp-eval-depth'`
An error would e.g be calling (some-nonexisting-function) from the REPL.
Additionally I get an error message inside the REPL itself. Sorry, for posting the whole thing here - I wouldn't know right now which parts are important:
box.webgl> (some-nonexisting-function)

recently CIDER was changed to automatically supply it's own cider-nrepl and clj-refactor middleware when starting lein, so you can (should) remove these from your ~/.lein/profifiles.clj file if you have them. This will clear up this warning. (remember to update to the latest cider emacs package.
WARNING: CIDER's version (0.12.0-snapshot) does not match
cider-nrepl's version (not installed). Things will break!
This is a problem and hopefully fixing it clears up your other problems. If not, at least solving this is a prerequisite to debugging it properly.
I cd'd into a directory containing two Scala classes.
C:\Kevin\Workspace\>dir
09/08/2013 09:13 PM 331 Max.scala
09/08/2013 09:13 PM 459 Test.scala
2 File(s) 790 bytes
2 Dir(s) 72,008,863,744 bytes free
Then, I opened up REPL:
C:\Kevin\Workspace\>scala
Welcome to Scala version 2.10.2 (Java HotSpot(TM) 64-Bit Server VM, Java 1.7.0_51).
Type in expressions to have them evaluated.
Type :help for more information.
scala> import java.lang.Runtime
import java.lang.Runtime
scala> val runtime = Runtime.getRuntime
runtime: Runtime = java.lang.Runtime#55dae09c
Then (with this post's help) I tried to compile my *.scala files via scalac as an argument to Runtime#exec, but it failed.
scala> runtime.exec("scalac Max.scala Test.scala")
java.io.IOException: Cannot run program "scalac": CreateProcess error=2, The system cannot find the file specifie

at .<init>(<console>:12)
at .<clinit>(<console>)
How can I do the above in Scala?
I think this is not so much a Scala thing as it is a Windows thing, which I infer from your first code block.
On my Mac, I find this:
scala> Runtime.getRuntime.exec("scalac")
res2: Process = java.lang.UNIXProcess#24c63dac
On Windows, try providing the fully qualified path to scalac. If that doesn't work, consider using ProcessBuilder instead.
The SML file: "test.sml"
(* here is a comment *)
val x = 123;
I've installed SMLNJ 110.76 from here: http://www.smlnj.org/dist/working/110.76/, Emacs 24.3.1 from here: http://ftp.gnu.org/gnu/emacs/windows/emacs-24.3-bin-i386.zip, and SML Mode for Emacs through the Emacs GUI.
The Emacs stack trace is this:
test.sml:1.2 Error: illegal token
test.sml:1.3 Error: illegal token
test.sml:1.5 Error: illegal token
test.sml:1.7 Error: illegal token
test.sml:1.9 Error: illegal token
and so on, ending with:
uncaught exception Compile [Compile: "syntax error"]
raised at: ../compiler/Parse/main/smlfile.sml:15.24-15.46
../compiler/TopLevel/interact/evalloop.sml:44.55
../compiler/TopLevel/interact/evalloop.sml:296.17-296.20
I also tried the same program via Sublime Text 3 with the SML and sublimeREPL packages as laid out here: http://developerinmotion.wordpress.com/2013/02/07/sublime-text-2-and-sml/. But I'm getting the same problem: a long list of illegal token syntax errors followed by:
C:\Program Files (x86)\SMLNJ\\bin\.run\run.x86-win32.exe: Fatal error -- Uncaught exception Compile with "syntax error" raised at ../compiler/Parse/main/smlfile.sml:15.24-15.46
What's the problem? Have I installed SMLNJ incorrectly?
I put your two lines in a file (test.sml) and opened in a standard SML REPL. It compiles normally:
- use "test.sml";
[opening test.sml]
val x = 123 : int
val it = () : unit
It seems that you have problems with setting your tools.
This problem may result from creating .sml file using UTF-8 character encoding. pls use ANSI instead.
I use the sublime open the ensime project, the ensime server started normal.
After using it for a short time, the following errors occured.
