What steps will reproduce the problem? 1. Download the .zip 2. unpack & navigate to the folder 3. run ./RunScalaLabLinux64.sh

What is the expected output? What do you see instead? Unsupported major.minor version 51.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:631) at java.lang.ClassLoader.defineClass(ClassLoader.java:615) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) at java.net.URLClassLoader.defineClass(URLClassLoader.java:283) at java.net.URLClassLoader.access$000(URLClassLoader.java:58) at java.net.URLClassLoader$1.run(URLClassLoader.java:197) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247)

What version of the product are you using? On what operating system? Mac OS X v10.6.8 Java version 1.6.0_33

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?

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!

Hi,

I am using Mac OS X 10.9 Mavericks.

martin@~/Desktop/ScalaLab211M5Oct22$ java -version java version "1.7.0_12-ea" Java(TM) SE Runtime Environment (build 1.7.0_12-ea-b08) Java HotSpot(TM) 64-Bit Server VM (build 24.0-b28, mixed mode) martin@~/Desktop/ScalaLab211M5Oct22$ ./RunScalaLabLinux64.sh Full Path of the main ScalaLab .jar file = jar:file:/Users/martin/Desktop/ScalaLab211M5Oct22/ScalaLab211.jar scalalabJarName = = ScalaLab211.jar Trying to load NR library [NROps.so] ... Current Path = /Users/martin/Desktop/ScalaLab211M5Oct22

... but ScalaLab does not start

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?
