Please provide any additional information below.
Hi, running ScalaLab perfectly on work Windows machine. Would love to get up 
and running on the Mac but can't get the code to compile. Is it a Java version 
thing?

Original issue reported on code.google.com by dlee...@googlemail.com on 17 Aug 2012 at 6:17

GoogleCodeExporter commented 9 years ago 
ScalaLab210 and ScalaLab292 require JDK 7, so you should install a JDK 7 
compliant on Mac. ScalaLab282 perhaps can run with Java version 1.6.0_33.

With the above explanation this should probably be in 'resolved' status. 
However (on OS X 10.8.4 and JDK 7.11):

$ ./RunScalaLabLinux64.sh 
fullJarPath = jar:file:/Users/asko/Sources/ScalaLab2102June12/ScalaLab210.jar
scalalabJarName = = ScalaLab210.jar
jarFilePath= = ScalaLab210.jar
GlobalValues.scalalabLibPath = lib/
Exception trying to read scalalabUserPaths.txt
$

Should I have a file named scalalabUserPaths.txt ?

By manually creating an empty file scalalabUserPaths.txt the command proceeds. 
And exits. I was expecting a GUI of some sort to pop up. Thanks for help.

face the same problem under Mac. Any solution yet? Thanks a lot.

I also have the same issues on a Mac

Mac OSX 10.7.5
Java 1.7.0_40

Here's what happens:

$ ./RunScalaLabLinux64.sh
Full Path of the main ScalaLab .jar file  = 
jar:file:/Users/primary/Desktop/Programming/ScalaLab/ScalaLab211.jar
scalalabJarName = = ScalaLab211.jar
Trying to load NR library [NROps.so] ...
Current Path = /Users/primary/Desktop/Programming/ScalaLab
$

it proceeds...then exits.

Any ideas?

Also, I try this on my Raspberry Pi running Java 1.8 SE Beta and get

"$ ./RunScalaLabLinux32.sh
Java HotSpot(TM) Client VM warning: INFO: os::commit_memory(0x68c00000, 
419430400, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 419430400 bytes for committing 
reserved memory.
# An error report file with more information is saved as:
# /home/pi/hs_err_pid3174.log"

anyone successfully get ScalaLab to run on either their Mac or Raspberry Pi? I 
really want to explore this program

Solved:

I used ScalaLab292July30.zip and ran ./RunScalaLab.sh

it launched on my Mac with no issues. Finally!

ScalaLab211June23 works, but ScalaLab211M5Oct22 and ScalaLab211Nov04 do not run 
on my Mac System.

The new ScalaLabAllFeb26.zip should now work on Mac OS X,
since I avoid to load missing native libraries.

It works?
