Max heap 512m [message #1067677]

I am trying to compile a program with a large header file, and so I tried to change the values in the eclipse.ini file. It will allow me to change all of the values except for the max heap size. That is stuck at 512 MB. If I make it any bigger, eclipse fails to start with "Failed to start the Java VM".Does anybody know a fix for this?

Thanks.

What did you exactly change in the eclipse.ini file? In principle, you should replace the line "-Xmx384m" with "-Xmx1024m".

I only changed the numbers. Everything else is "out of the box". The settings shown below cause the error. If I change it back to -Xmx512m it works fine.

-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20130521-0416
-product
org.eclipse.epp.package.cpp.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
1024M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
1024m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Xms256m
-Xmx1024m

You should not increase the XXMaxPermSize.
