Need help in building openjdk on ubuntu 11.10

[Kelly O'Hair]

The makefiles are not prepared for building on Linux 3.0 kernels yet.

Try applying this patch:

diff --git a/make/linux/Makefile b/make/linux/Makefile
--- a/make/linux/Makefile
+++ b/make/linux/Makefile
@@ -230,7 +230,7 @@
 # Solaris 2.5.1, 2.6).
 # Disable this check by setting DISABLE_HOTSPOT_OS_VERSION_CHECK=ok.
 
-SUPPORTED_OS_VERSION = 2.4% 2.5% 2.6% 2.7%
+SUPPORTED_OS_VERSION = 2.4% 2.5% 2.6% 2.7% 3.0%
 OS_VERSION := $(shell uname -r)
 EMPTY_IF_NOT_SUPPORTED = $(filter $(SUPPORTED_OS_VERSION),$(OS_VERSION))
 


However, I can't be sure that is the only change needed.
