[Laszlo-dev] Wiki Subversion Build Instructions/build problems

[P T Withington]

Thanks for this, Lou.

It seems that _something_ I have done to the build system has resulted in us requiring JDK 1.6.  Not sure what.  Perhaps Ant 1.7 requires it, or perhaps some of the updated .jars require it.  I don't think this is too much of a problem since Sun has declared 1.5 at "end of life" as of last November; but perhaps I am wrong?

I have a Leopard (10.5.8) here which is up-to-date on all it's software updates.  I can see that JDK 1.6 is "available" it is just not the default java that you get.  I had to open /Applications/Utilities/Java Preferences and drag Java SE 6 to the top of both lists in order to make my command-line java default to 1.6 [Have I told you how much I love the Java version number scheme?]  I think that is the more orthodox way to get Leopard to run JDK 1.6; but if you need to leave you default java alone, setting your JAVA_HOME for just your OpenLaszlo builds as you did is a reasonable alternative.

As to not being able to build the docs, it looks like you need to allocate more memory to java.  I run with:

export JAVA_OPTS="-Xmx768m"

on my machine, although I can't say I have built the docs lately.
