[gridengine users] issue on build GE2011.11

[Ron Chen]

Is it possible that you have more than 1 JRE or JDK installed on your system? Otherwise the compilance level should match.

It's very likely that you have JDK 7 on your system, or some class files were compiled by JDK 7, or else it should not give you that error.

Java 1.5 is major.minor 49

Java 1.6 is major.minor 50

Java 1.7 is major.minor 51

Again, you can google search for this java.lang.UnsupportedClassVersionError exception, and almost always people solve it by using the correct compilance level of JDK and JRE.

Hi Ron,
Thanks for your quick feedback, however I am running this on Ubuntu 10.04 (as mentioned in my email).

Looking and your suggestion, but if I understood you correctly seems like my versions are ok?

root at server:/opt/grid# java -version
java version "1.6.0_30"
Java(TM) SE Runtime Environment (build 1.6.0_30-b12)
Java HotSpot(TM) 64-Bit Server VM (build 20.5-b03, mixed mode)

root at server:/opt/grid# javac -version
javac 1.6.0_30


Thanks
Laurence

Can you check the generated config.log in the 3rdparty/qmake/WIN32_X86 directory? Usually, the last few lines of the config.log file tells you why the compilation fails.
